Here Quick and narrated failures to solve the problem

computer malfunction that appears confusing, puzzling. And the components of the Windows operating system is relatively intricate, computer accident of a failure, for the mean user, you ambition to pinpoint the reasons for its failure is about impossible. So it is that if we encounter when the computer failure, completely helpless out? This is not so, the computer-generated however there are many reasons for failure, but if we look carefully, conscientiously amount up, we can still have some computer failures of the law and treatment reaches. In this pamphlet, we will some of the most common and most typical computer fault diagnosis, conservation means to show you, via it, you'll find - ways to solve computer failure on your side, easy, but efficient!


one motherboard motherboard

opener makeup of the whole computer, the computer plays a vital character. If the motherboard breakdown will affect the go of the whole PC computer system. Here, we take a see at the motherboard in the way of which the maximum common mistakes.

a common fault: shoe no display no display

computer boots, the first entity to check is a BIOS. Motherboard BIOS, the hardware store momentous data, when the motherboard BIOS is part of the more vulnerable, easily damaged, once damaged it will cause the system can not run, the recurrence of such failures are generally due to the motherboard BIOS damage caused by CIH virus (of course not rule out the motherboard itself, cause a system failure can not run..) General BIOS hard drive after the virus destroyed the data will be lost, so we can find the hard disk the data is intact to resolve if the BIOS is damaged, if the hard disk data intact, so there are three reasons why the phenomenon of power no display:

1. because the motherboard or expansion card expansion slot problems, leading to plug in expansion card, such as sound cards, etc. without the display board is not answering.

2. motherboard jumper settings in the CMOS in the CPU frequency does not, it may lead to not show fault, which, as long as the clear CMOS to be addressed. Clear CMOS jumper on the motherboard usually near the lithium battery, the default place is generally 1,2 short, fair short of his conversion to jump a few seconds for the 2,3 to solve the problem, the old motherboard for the past can not be found should the user to the jumper, just remove the battery, enter the CMOS settings to be displayed after the boot off, will go up also reached the CMOS battery expel purposes.

3. motherboard does not recognize the memory, memory corruption or memory does not match the boot no display can lead to failure. More selective in some older motherboards memory, once the plug in the motherboard does not recognize the memory, the motherboard will not begin, and even some motherboards do not give you anybody fault tips (tweet). Of course sometimes in order to expand the memory to amend system rendition, the results of different plug brands, types of memory can also cause such a failure occurs, so maintenance should disburse more attention.


for the failure of the motherboard BIOS is damaged, we can plug in the ISA card to see whether the display (If prompted, can prompt steps below.), if not the boot screen, you can own Automatic Updates BIOS to do a floppy disk, reload the BIOS, but some motherboard BIOS is damaged, the floppy drive did not work this time, try using hot method to solve (I have tried, at the peak of the BIOS the same at the same level of motherboards can be successful writer..) However, in addition need to use the same BIOS hot asset, some components may cause damage to the motherboard, so a authentic method is to write code using the BIOS update file to write device inside the BIOS (this service can find a safer computer vendjust aboutlution).

Troubleshooting II: CMOS settings can not be saved
such failures are generally due to insufficient battery voltage caused by the motherboard, which can be replaced, but some board battery replacement also can not solve the problem, at this time There are two possibilities:

1. motherboard circuit problems, which are looking for vocational service;

2. motherboard CMOS jumper problem, sometimes because of the error will bound on the motherboard CMOS line is set to remove the adoption, or set to an outer power cell, production the CMOS data can not be saved.

Fault Three: In Windows, install the motherboard driver CD-ROM drive read the disk after a crash or slow down the phenomenon

in some no-name motherboard sometimes such a phenomenon, motherboard drivers programs Bahrain, can not restart the computer into the Windows 98 desktop, normal mode, and the driver beneath Windows 98 can not be uninstalled. If this occurs, it is suggested to re-find the latest drivers installed, the problem can be solved generally, if it is not, can only re-install the system.

Troubleshooting four: Install the Windows or start Windows when the mouse is not available

recurrence of such failures in the software causes the error is generally caused by the CMOS settings. Power treatment settings in the CMOS has a modem use IRQ field projects, and his options are 3,4,5 ......, NA, generally it is the default option is 3, set it to 3 other than items can be disturbed.

five common faults: frequent microcomputer breaks, during the CMOS settings ambition arise the phenomenon of decease

Dead phenomenon happened in CMOS, usually the motherboard or CPU have problems, should the press law can not troubleshooting, it can only replace the motherboard or CPU.

such failures usually occur because of a problem with the motherboard or the motherboard designs Cache heat caused by bad, I had found in the 815EP motherboard is not good enough for the motherboard heat caused by the failure phenomenon. Touch the CPU after the crash around the motherboard components, found that the temperature is very hot. After replacing the high-power flare, crash failures can be resolved. Cache problem for the failure, we can enter the CMOS setup, the Cache can fix the problem after the ban, of course, Cache forbid would surely be an clash upon the speed.

Troubleshooting Six: board COM port or parallel port, IDE port failure

the recurrence of such failures are generally due to causes related hardware peppery plug the user, the user can use this time instead of multi-function card But in lieu must be deterred before the COM port on the motherboard comes with the parallel port (some motherboards with IDE ports to be banned for appropriate use.)
graphics
a common fault: boot no display

such failures are generally due to poor contact with the motherboard or graphics slot motherboard causing problems. Fjust aboutme integrated graphics motherboard, main memory if the shared memory, you need to pay attention to the location of memory, usually in the first memory slot should be inserted in memory. Causes the graphics card no display power failure, power is generally given after a long, two short beeps (AWARD BIOS for the card is concerned).

Fault Two: Show Huaping, blind to the handwriting

such failures are generally due to high-resolution monitor or video card does not support caused. Huaping startup mode can be switched to safe mode, and then again in Windows 98 into the display settings, select the state in 16 colors Restart in normal mode Windows 98 system, delete the graphics drivers, restart the computer. Or not to enter safe mode, in a pure DOS environment, edit
SYSTEM.INI file, display.drv = pnpdrver to display.drv = vga.drv, the Save and exit, then drive in Windows to update the
program.

three common fault: color display is not normal, such failures are generally the following reasons:
1. graphics card and monitor signal line is bad
2. display their own fault
3. In Some software to run when the color is not normal, usually common in older machines, there is a check in the BIOS, the color of the option to open it to
4. Graphics damage;
5. display is magnetized Such phenomenon is generally due to magnetic objects can be caused by too close, magnetized may also cause the display appears deflection phenomenon.

Fault IV: Death

the recurrence of such failures are generally more common in non-compatible motherboards and graphics cards or motherboards and graphics cards bad; graphics card is not compatible with other expansion cards can also cause crashes.

five common faults: the screen pattern of erratic noise or

such failures are generally due to problems with memory or graphics cards caused by poor contact with the motherboard. Finger position to be clean or replace the graphics card was
card.

six common faults: lost

graphics driver graphics driver to load and escape automatically after a phase of detriment of driver, such failures are generally of meager quality due to video card or graphics card and motherboard do not compatible, making the graphics card temperature is too high, causing the system to run unstable or freezes, then only replace the graphics card.

counting, there is a level of special circumstances, the before graphics driver to load, but the graphics drivers loaded into Windows when the crash occurred. To change to other types of cards in loading its driver, insert the old card to be addressed. Should such a failure can not be decided, then the registry failure to restore the registry or reinstall the operating system can be. A common fault

sound: sound dumb. There are common causes of this failure:

1. Default output driver is Click the sound icon base right corner of the screen (small microphone), appear to adjust the volume slider under the

2. soundcard conflict with other cards. PnP card solution is used to adjust system resources so that all cards without disturbing each other. Sometimes, open the

3. After installing the Direct X sound card is not audible. That this sound card with Direct X compatibility is not nice, need to update the driver.

4. one channel silent. Check the sound card to the audio speaker cable is disconnected.

two common faults: excessive noise from the sound card. There are common causes of this failure:

1. Card is not correct. Manufacturing precision is not high enough because the chassis, sound card manufacturer or installed outside the damper caused by bad sound card can not be closely integrated with the motherboard expansion slots, can be seen visually on the card This phenomenon in the ISA card or PCI card has, are common problems. Pliers generally available improvement.

2. Active Speaker Speaker input connected to the sound card output. For the spirited speaker, should be connected to sound card Line out side, it has not been
output signal amplifier on the card, the noise is much smaller. There is only one output card is the Speaker or Line out jumpers on the card depends on the decision, the plant default is often Speaker, so the jumper to disconnect the sound card.

3. Windows comes with a bad driver. Sound card driver is installed, you should select the list box. If you have installed the Windows driver that comes with the optional Installation. Then insert the disk or CD-ROM with sound card, load the driver provided by the manufacturer.

Fault Three: Sound can not I once had a sound card under Windows 98 using the original driver disk to install the driver setup does not stuff how, and had to replace the use of Creative SB16 driver, everything is normal. Then upgrade to Windows Me, not normal and back with Windows 2000 (full edition) comes with just the normal sound card drivers.

2.'s most vexing problems than the Windows 9X Plug and Play device under test has chosen to given a free hand to help you install the driver, the driver side is not used, then, each time you delete out reloading will repeat this, and can not use the Here I reveal a mysterious detached trick: Go to Win9xinfother directory, the *. inf file on the sound card, delete all and restart manually after installation, this was one hundred percentage effective, have saved countless lives ... ... of course, sound card, change up table can accomplish the same purpose.

3. does not support the PnP sound card installed (also applies to not use the PnP install the PnP sound card): Go to Windows search for new hardware?

Troubleshooting four: Play CD silent


1. completely silent. With Windows 98's Using a 4-pin CD-ROM audio cable to connect the analog audio output and CD-in on the card can be, this line will purchase CD-ROM contained.

2. there is only an aisle sound. Optical output marking generally about two lines, the navel two lines to floor. Because the audio marking line 4 line color is generally assorted, can be found from the color of the line correspond to the interface. If only one interface or sound card and audio cable for every interface does not match the wiring had to change the order of the audio line, usually only one of two lines of the change can be.

five common faults: PCI sound card appears sonic boomPCI graphics card
generally because technology reasoned along hanging Bus Master PCI bus hard disk peruse and write, mouse actions and other operations apt distend the backdrop rumpus
reason. Solution: Turn off the Bus Master PCI card features into AGP graphics card, sound card for the PCI slot.

six common faults: not the normal recording

first check if there is nought erroneous with the loudspeaker jack into the other, and second, double-click the little speaker, select list see if the settings are correct. Then in the If the

seven common faults: Can not Play Wav's, Midi Wav Music

can no melodrama melody phenomenon namely rare, often deserving to One can disable; can not play MIDI files may have the following 3 possible:

1. Early ISA sound card 16-bit mode may be due to 32-bit mode is not compatible with the MIDI playback is not caused by the normal, by installing Software wave table
way should resolve

2. Today, most of the renowned PCI sound card with wavetable synthesis technology, if the MIDI playback is not part of it is likely because you do not load the appropriate sound wave table library.

3. Windows volume control in the MIDI channel is set to silent mode.

eight common faults: PCI sound card to use in the WIN98

Some users do not usually reflected in the sound card driver installation process anything is customary, not apparatus conflicts happen, merely the following is not in WIN98 loudly, or cause other problems. This phenomenon routinely occurs in the PCI sound card, please check the installation process your PCI sound card inserted in the treatise which PCI slot. Thermal attentions as some friends, favor to stay away from the sound card plugged into the AGP slot, approach the ISA slot namely several PCI slots. The problem often arises here, because there is a Windows98 Bug: sometimes merely correctly identified and inserted in the PCI-1 PCI-2 sound card two slots. ATX motherboard in the two next to AGP is the PCI-1 PCI and PCI-2 (the inverse in some ATX motherboard, near to the ISA is the PCI-1), so whether you do not have the PCI sound card installed in the correct slot, the problem would be built.
memory


computer memory is one of the most important parts, and its role in mistrust, then the memory what are the most common faults it?

a common fault: no display

boot memories because the recurrence of such failures are generally due to memory with the motherboard memories slot is bad cause, as long as smear his finger back and ahead with the eraser location to solve the problem (Do not use liquor and other cleaning), there is memory corruption or a problem with the motherboard memory slot can also cause such a failure.
memory causes the boot no display failure, the host speaker beep usually for a long time (for the Award Bios is concerned).

Troubleshooting II: Windows Registry damage often for no reason, reminded for a user to regain

such as memory failures are generally caused by poor quality, it is difficult to repair, replace only one way .

3 common faults: Windows constantly automatically enter secure mode

such failures are generally due to the motherboard is not compatible with the memory or memory caused by poor quality, common in high-frequency memory for Some do not assist this frequency of memory on the motherboard, you can attempt to dwindle the memory within the CMOS settings to discern whether the read speed to solve the problem, should not, it can only replace the memory.

Fault IV: promiscuous crashes

such failures are generally due to the adoption of several different memory chips, due to the memory of different speeds to produce a time feud resulting in death
machine, which can reduce the memory speed CMOS settings to be resolved within, otherwise, the only way to use the same type of memory. Another feasibility is that memory is not compatible with the motherboard, these phenomena generally rare, the other is also possible that poor contact with the motherboard memory computer random crashes caused. 01

five common faults: memories to amplify system resources, but decreased after the

such phenomena are generally not compatible with the motherboard and memory caused the high frequency of memory commonly found in memory fknow next to nothing ofme does not support this frequency of memory on the motherboard, such a failure when you try to COMS memory speed will be set too low point try.

six common faults: some software often runs out of memory prompts

This phenomenon is usually due to inadequate system disk space left, you can cancel some useless files, leaving some space that is can be generally maintained by
300M or so.

Fault Seven: Install Windows to boot from the hard drive to detect disk space, memory

prompted such failures are generally due to the user in the config.sys file, add the emm386.exe file, at the peak of it masked problems can be solved. CD-ROM drive is

computer hardware components in one of the shortest life. In fact, many scrap the drive there is still much of value, just click on it a little maintenance. This often do not have any mysterious knowledge of radio, do not need anything too intricate to use the repair tools and materials. Just look carefully and with reference to the implementation of the following symptoms of some troubleshooting, I believe you can restore the old drive or the old

common fault I: drive is always working hard disk light flashes

This is an illusion, it is not. Because of the hard disk light flashes and the hard disk drive with an IDE interface connected, the disc also control the hard work the results of light. Drive element can be connected to a unattached IDE interface.

Fault Two: In the Windows environment to manipulate on the CD-ROM to display ROM to a certain extent. Most CD-ROM connected to IDE hard drive interface does not support
Windows 32-bit disk access, the Windows generated an interior error crash. After entering Windows, the check box is closed, the confirm, then restart Windows, in Windows, and then access the CD-ROM will not work into error.

Fault Three: drive can not properly read the disk, displayed on the screen: FALL?

In this case, the virus should be detected by antivirus software on the machine to check anti-virus, the virus can not find the file if the editor to open C under the basis directory of the CONFIG.SYS if they put up light drivers and drivers are broken, and processing, but also with a txt editing software View . If the above two treads do not find problems, removable drive maintenance.

Troubleshooting four: drive to use when prompted to read and write errors or diskless

this phenomenon mostly in the changer If we can not area aboard the operation of the drive caused the failure. aboard the drive always the operations will must wait for the record light is like the bit ahead the operation. in the DVD player ought be the period to naught when When plucks disk, so you can lest the upon error.

five common faults: when playing VCD videos cease or broken screen phenomenon

check the AUTOEXEC.BAT file br>
six common failures: CD-ROM in the read data, read and sometimes not, and the longer the time to read the disk drive

not read the disk hardware failure focused on the laser brain gathering,Fitness Diary moved to fitness sites, and can be divided into two kinds: one is caused by using long laser tube of the antique
; the other is the photocell lens surface is polluted or dirty and displacement of the laser tube distortion. So the power to adjust the laser tube , the need for optical tube and lens cleaning laser tube.

photoelectric tubes and focusing lens cleaning method is: Disconnect the laser head assembly, a smooth cable, remember the direction of the laser opened head assembly. then see hooded jacket laser focusing lens, remove the jacket will find that focusing lens from the four fine copper wire connected to the focus, tracing the coil, the optical tube assembly is installed in the lens holes in the bottom. with a nice wire mantled in a small amount of distilled water and clean cotton stick (not with an alcohol wipe the surface of optical lens tube and focus), and to see whether the level of the lens on the laser tube is suspended, it shall be adjusted suitably. At this point, cleaning completed.

to adjust the laser head power. in the side of the laser head assembly has a across like a small screw potentiometer. the use of color and write the initial position, generally the first clockwise 5 ° ~ 10 ° , not re-installed test machine counter-clockwise 5 ° ~ 10 °, until a smooth read the disk. attention must not swivel too much, so much power and burned photocell.

seven common faults: power can not be detected to drive or test failure

This may be due to steer the data line connector is lax, marred or the hard disk steer data cable jumper settings error caused by such problems encountered when
waiting, we should first Check the drive data cable connector is loose, and if found not plugged in, it will be re-plugged, plug firm. If this does not resolve the failure, then we can hosts put on a new data line to try. this time If the fault still exists, we need to check the jumper settings CD-ROM, and if there is an error, change it to.
mouse mouse
failure analysis and maintenance is relatively simple, most of the fault for the interface or button bad, broken, dirty mechanical positioning system. a few failures for the internal components or circuit Weld mouse, which are found in certain low-quality products, especially in the light-emitting diode, IC circuit damage to the bulk.

A common failure: can not find the mouse

1. mouse completely damaged and need replacement mouse.
2. mouse chained to the host reg code port or PS / 2 spoken exposure bad, take a good line after cautious , restart you can.
3. motherboard serial or PS / 2 ports from getting damaged, this situation is rare, if this is the circumstance, had to replace a motherboard or a serial port on the multi-purpose card.
4. mouse line is bad, this is the most common. bad points more in the mouse inside the wire and circuit board connections. fault by the time not dissimilar PS / 2 joints, the common is not laborious to repair. usually is due to relatively short lines, or contrast the mouse lines are messy and lead to the reasons for pulling coerce, the solution is to open the mouse, and then use a soldering iron to solder weld. there is a location that is bad inside the mouse cable is due to the time caused by the aging caused by long, this failure is often difficult to find, replace the mouse is the fastest solution.

two common faults: the mouse can be shown, but can not move the mouse flexibility

ebb, not as dictatorial pointer, but slow, incorrect positioning, or simply could not move. This is chiefly due to mechanical positioning the mouse scrolling axis in the collection of transmission failure caused by excessive clay, resulting in Scroll is not amenable. converge on maintenance within the mouse Y axis X axis and the transmission machinery. The solution is to open the lock piece rubber ball, roller ball mouse unloaded, with a clean napkin dipped in neutral cleaner cleaning of the rubber ball, the friction shaft can be cleaned with alcohol. The best place in the Axis drop a few drops of sewing machine oil, but it must be careful not to flow to the friction surface and the seam on the grid encoder. will remove all the clay After the flexibility of the mouse ever resume.

three common faults: the mouse button failure

1. the mouse button without movement, this may be because the mouse buttons and circuit board from the micro switch Click the switch too distant away or after a period of reduced competence to use the bounce. open the mouse, the mouse buttons below the temperate thickness of glue a piece of plastic film, the thickness is determined according to actual needs, can be used after treatment.

2. the mouse button is not the normal pop-up, this may be because when the key alternate in the bottom of the bowl-shaped micro-fracture caused by exposure to movie, especially the long-term use of plastic is easily broken reed. If a three-button mouse, Then you can remove the middle of that one key to the emergency. If it is good quality original brand-name mouse, you can solder, the open mini alternate, carefully clean the contacts, some of the grease, the flasks can be used.
Keyboard
keyboard in use, failure declarations are varied, the reasons are multi-faceted. There is bad failure, mechanical failure has its own keys, as well as logic circuit fault, Weld, artificial welding, sealing off holes and metal oxide and other failures. repair the fault phenomena according to the analysis of different decrees, find out the cause of the malfunction, make the appropriate repairs.

a common fault: some of the keys on the keyboard, such as space bar, Enter key does not work, sometimes, adjustment shall be entered many times before - one or two characters, and some
keys, such as the cursor key is pressed is no longer together, continuously moving the cursor on the screen, this other characters can not be entered when the keyboard is required to press repeatedly to bounce
.

this failure as a keyboard How long will the new keyboard, the keyboard's card key failure is also sometimes occur. there keyboard card key phenomenon caused by the following two reasons: one reason is that column keycap insert the following position offset, making the keycap is pressed stuck with the key body shell is not caused by a card key bounce, this occurred because the keyboard or use a new keyboard soon. Another key reason is that long-term use, the return spring elasticity becomes poor, shrapnel and press the pry friction becomes larger, can not make key bounce caused by card key, because this occurred in the long-term use of the keyboard. When the keyboard appears when the card key fault can be apportioned under the keycap, and then press the lever press. If the press projectile is not up or fatigue, is caused by the second, otherwise the first causes. If the keycap and the key causes the body shell stuck in the and put a gasket between the key body, the gasket can be slightly harder some of the plastic (such as discarded diskette jacket) made of, its size is equal to or slightly larger than the key to body size, and press the lever in the open position by a the free corridor of ammonium square hole shot, to set in at pole, plug keycap; with the keycap and the key pad to stop the body stuck, you can repair problems button; if the spring fatigue, shrapnel resistance to change caused a large card key to failure, then the body can be special key to open, a little traction return spring to restore bounce; remove the shrapnel will be key to the restoration. by removing the shrapnel and reduce the resistance by rod bounce, so failure keys have been restored.

Fault Two: Some characters can not enter.

if I were you one key character can not enter, it may be the key failure or joints Weld. check , according to the method described above, open the key
disk, weighed with a multimeter resistance outline of the on-off status of contacts. If the key does not forever turn on when pressed, then button reed fatigue or bad, in need of repair or replacement; if key is pressed off normal contacts, that may be due to chilly solder mutual, sealing off holes or gold scrap due to oxidation can be measured forward the printing line, paragraph by paragraph, to find fault re-welding; Ruoyin oxidized metal aperture failure oxide floor can be cleaned and re-weld; if caused by the metal cavity entirely off circuit, it can lead to join annexed soldering.

three common faults: if it were not for in the same column number, but also the keys are not in the same line can not enter.

line or lines may be lines elsewhere in the column circuit, or logic door circuits may be malfunctioning. 100MHz when used to detect high-frequency oscilloscope to find fault device Weld point, and then repair.

four common faults: keyboard input is inconsistent with the character screen.

such failure may be due to the phenomenon of short circuit caused the board, and its performance is based on the key are shown as the same as the other characters, this time can be measured multimeter or oscilloscope to determine the point of failure after repair.

five common faults: Press a key to produce a string of multiple characters , or when the character key bounce.

This phenomenon is caused by a logic circumference failure. premier elect a col of characters, if the enter key of a row without a col, may generate a digit of other characters phenomena; if a column with the Enter key, the persona will have a gambol into the system and can not be the last phenomenon, check the logic circuit chip with an oscilloscope to detect fault with the prototype after the replacement of the chip of the fashionable chips, troubleshooting.
Modem
a common fault: 56K of Modem not up to 56K. This problem can be from the following considerations:

1. 56Kmodem actual maximum speed can only reach 53K know next to nothing of, to consider various effects, 56Kmodem speed is generally between 45-53K.
2. Modem telephone line to a colossal extent affected the displacement rate, if the phone line quality is not good, line voltage instability, 56K Modem
to last fewer than the 56K; other use of the Internet enhancement will also affect Internet speed.
3. not installed the correct driver.
4. and the ISP uses different protocol, only your Modem and your ISP approval is the same, Modem will meet the criterion 56K.
exclude the above reasons, your 56K Modem is still much faster than 53K, this is your Modem hardware problems can be considered a replacement or repair
.

Troubleshooting II: Modem disconnects often, the problem may have dripped the following reasons:

1. Phone line quality is not good;
2. If the data terminus prepared (DTR) signal is ineffective chronic for more than Modem default settings, it will lead to dropped calls;
3. If your call has a
break;
4. In addition, Modem their quality and compatibility problems between different Modem Modem is caused by a common cause of dropped phones.

three common faults: Modem no dial Music

time when the Internet late at night when the dial tone in order not to influence others slumber, through the suitable AT bid to change: You can use the ATM0 set Modem no dial tone, and ATM1 set to the connection from dial-up Modem When a dial tone. For the choice of the volume you can change the following directions, ATL0 (low volume), ATL1 (low volume), ATL2 (in volume), ATL3 (high volume).

four common faults: fax rate 14400

Modem reach the maximum fax rate is 14400, and send a fax rate of only 9600. This is because most of the fax machine to mail and receive rates are
is 9600, and only use the rate is 14400 or 33600 fax, Modem fax speed will reach 14400.

five common faults: Modem can not dial or connect

if I were you installed correctly on your Modem, communication will be not work properly. The following lists the authentication process of the communication Modem with Windows installed an incompatible driver files, may cause COM ports and the Modem is not working properly, it should first check if the correct Windows98 loaded file.

1. Testing existing communication file
(1) the System catalogue and SERIAL.VXD COMM.DRV Windows95 floppy disk or CD-ROM file with the original file to compare, check documents collared
is the same size and appointment.
(2) confirm the System.ini document in the following lines: [boot] Comm.drv = Comm.drv [386enh] device =* vcd
(3) in the ; Control Panel embodying it. In addition, there is no System.ini in
* VCD associated with the file. These files are built in at the VMM32.VXD.

2.
test the modem's configuration in the ; Control Panel your modem does not appear in the list of installed modems
, click the type, try to use Conflict in the exclusion list, remove all the modem entries.

3. Check that the modem is in a state of
can use the modem and click

4.
check the correctness of the port in the If not, please select the correct port, and then click

5. confirm the serial I / O address and IRQ settings are correct
in Click the Set in the Change Settings
Note: If the mouse on COM1 or other equipment, please do not use the modem on COM3. Usually COM1 and COM3 ports use the same variety of
IRQ, and in most computers can not be used. COM2 and COM4 have the same problem. If feasible, change the COM3 and IRQ settings
COM4 wharf, so they no longer clash. Also, some graphics card and COM4 port addresses conflict, the conflict if found, use the other ports, or replace your graphics adapter.

6.
test port settings in

7.
test the modem baud rate in the
Note: If you call the main system to set the baud rate in the original can not communicate, then reduce the baud rate can sometimes resolve the problem.

in the bureau printer, ink jet printer is then used in a more general one device. Inkjet printers due to the use, maintenance, unfit operation and other elements will often be some failures, how to address the concerns of the user. Here we put in the journal work and treatment of common faults summed up, we want to help.

a common fault: printing ink scarce, illegible handwriting processing, most of the fault is due to the long-term untouched printers or other reasons, resulting in the ink delivery system disorders or nozzle clogging.

exclusion: If the nozzle clogging is not very mighty, then the implementation of the printer instantly to the cleaning operation. If no achieve after repeated washing, you can obtain the cartridge (one for non-printer cartridge nozzle, the nozzle need to obtain, but the need to cautiously), put the nozzle in lukewarm water soak for a while, note that the circuit boards have to not some are soggy in water, or else, dyed with digestive periodical to take away the water droplets, and then washed several nozzles installed on it.

Fault Two: Replace the new ammunition, the printer in the boot plate on the to do Replacement ink cartridges, the printer panel on the new cartridge. As to replace the publish cartridge, printer ink will dictate the ink distribution system, and this process can not be turned off, so the printer can not detect the re-install the cartridges. In addition, some printer ink capacity of the dimension is the use of electronic counters inside the printer to the calculate (primarily in the use of color ink on the statistics), when the counter reaches a certain amount, to determine the printer ink tired. In the ink cartridge replacement process, the printer will carry out its internal reset the electronic counter, thus confirming the installation of a new cartridge.

Solution: Turn on the power, the print head moves to the cartridge replacement position. After installing the cartridge, so that charge printer ink, ink filling process is finished, troubleshooting.

Troubleshooting III: Treatment of head

soft soft plug plug plug manner that for various reasons on the viscosity of the ink in the nozzle due to the damage bigger fault. General use elemental ink cartridges can be restored after repeated washing, but this is direction too wasted ink. The easiest course is to use your hands to the head of vacant cartridge cleaning. Before cleaning with an blank cartridge, first using a prod as the cartridge out of the residual ink, the cleaner the better, then multiplication the cleaning solution (obtainable aftermarket). Filling cleaning fluid should be carried out in a clean surroundings, will increase a good cleaning fluid cartridge according to the normal operation of the printer on the machine, and constantly cleaning the printer button at its cleaning. Use of the residual ink cartridge cleaning fluid mixed with light colors for printing the test, then put on a good cartridge for normal use.

Troubleshooting four: Clean the pump nozzle in the printer troubleshooting

something wrong with the printer is more wash pump nozzle, and it is one of the cardinal factors causing plug. Cleaning the printer on the printer nozzle pump nozzle protection plays a crucial role. After the car back to the bit nozzles to clean the pump nozzle from the nozzle to the languid pumping of treatment on the nozzle seal protection. Install a new cartridge in the printer or the nozzles are disconnected, the machine's suction pump to the bottom nozzle for exhaust through it, the higher the precision of this work mouths as possible. However, in substantial use, its performance and air tightness due to time, the dust and ink residues in the mouth of the coagulum increases. If the user is not on its regular inspection or cleaning, it will keep your print head out of some failure.

conservation of this part of the method: Remove the printer's altitude cover away car, using a needle wash them inhaling pure water, in particular, embedded within the pores of the jaws to fully clean the gasket. In this wish to caution users to clean the parts, do not use ethanol or methanol to clean them, this will cause this component liquefied in the mosaic of the porous gasket deformation. The other thing to say is that inkjet printers should be kept away from the heat and dust of the work environment, only a good working environment to ensure long-term regular use of the machine.

5 common faults: normal and printing ink line detection precision was significantly aggravate manipulation

inkjet printer in use due to use of the frequency and time and print accuracy become worse. Inkjet print head is also a life. General use from the beginning of a new nozzle to the end of life, could not see any fault if more smoothly, that is, the measure of cartridge life of 20-40 months. If your printer has been in use for a long time, and now the printing precision variation, you can use the method of replacement cartridges to try, if for a few cartridges, print output results are the same, then you will this printer's nozzle to be replaced the. If there is a change after the replacement ink cartridges, ink cartridges that you may have used poor quality non-original ink.

If the printer is new, the printed results can not satisfy you, often the print line is not clear, text skew graphics, text, graphics appearance the boundaries blurred, print out the ink control synchronization accuracy, this means you can buy cartridges to be false or non-original ink cartridges used in products, should be its instant replacement.

Troubleshooting six: walking car treatment

dislocation meet inkjet printer is a wading trail car alloy of bronze abrasive from the two sets of circular iron shaft with a accuracy composition of sliding completed . While walking there is a small car designed and installed to supplement the shaft lubricating oil Felt, but the environment we live in the dust everywhere, a long time, due to air oxidation, dust the surface of the destruction of the axis of the aging oil failure, then if it continues to use the printer, will be due to copper sleeve axis and the increased friction caused by car peregrination dislocation, can not be used until the collision caused the front.

solution is: Once this failure should immediately turn off the printer, did not return to place his hands back into the car parking spaces. To find a small chip of absorb or felt,PULSERA TRANSPARENTE CON FRANCIA, full of oil submerged on the sewing machine oil, tweezers grip rub back and forth on the spindle. It is best to remove the spindle, the cleaned oil, so the best.

encounter another automobile because of damage caused by the device. Car parking spaces above the printer have a photoelectric sensor, which is available to print to the printer board reset signal the importance of car components. If this component is too large or damaged due to dust, the printer can not find the car back to the signal due to buffet the front, which led to not use the general out of the failure to replace the device.
display
Display in a long time, a variety of small problems will follow. Experts trust that, to solve these little problems is actually very simple, with a couple of eyes can see the fault lies.

a common fault: just getting on the computer screen of machine shake so badly, and sometimes even the icons and text are not clear, but after twelve minutes and then will return to normal.

this phenomenon occurred in watery weather, damp inside the monitor's sake. To solve this problem, use damp sand in the edible packaging to string attach with cotton thread, and then open the back cover of the monitor will hang in the damp sand near the end of the tube nape tube near the tube socket. Thus, even in wet climate, it will not appear above the

Troubleshooting II: computer boots, the display is only listened and not seen the painting, dingy. To wait several minutes to appear on the screen.
seat tube leakage is due to be replaced sockets. Open the back cover to see the end of the tube a small circuit board, sockets to solder on the circuit board
. Carefully remove this circuit board, and then welded pipe under the seat, to the electronics store to buy back a seat the same tube, tube socket weld and then returned to the circuit board. Then install the board not to rush back to first find a small piece of sandpaper, very carefully, after the end of the tube protruding pin wipe clean with sandpaper. In particular, pay attention to pin on the oxide layer, if not clean lustered soon relapse. The board back together and you're done.

three common faults: display screen, there will always be staying clutter interference or lines, and the speaker also has needless noise.

This phenomenon is mostly caused by poor power supply interference. If you too slothful to get comprised, you can replace a new power supply. If you have enough hands to
power, you can also try to replace the power within their own filter capacitor, which often can be effective; if the result is not apparent, you can switch
to be replaced.

four common faults: display Huaping.

graphics on this issue is caused by more. If it is new for the graphics card, the card may be of poor quality or antagonistic, then there is by far installed the correct driver. If the old card and added memory, then there may be new graphics and additional to the original model parameters vary due to memory.

five common faults: display a black screen.

graphics card if it is damaged or broken monitors and other causes no signal sent to the display, the display will stop flashing lights did not receive prompt signal. If the resolution is set too high, more than the maximum resolution the display will appear dark, severe havoc of the monitor, but now the display has a protective function, when the resolution exceeds the set value is automatically protected. In addition, conflicts can also cause black hardware.


display jitter causes



monitor refresh rate is set too low

set when the monitor refresh rate below 75Hz, the screen often there will be jitter, flicker,24-hour conservation usage of cervical, the refresh rate properly heaved, such as the set above 85Hz, the screen jitter phenomenon generally not occur again.

power adapter from the monitor, and chassis work too close to

power transformer will cause greater electromagnetic interference, causing screen jitter. The power transformer on the chassis and the monitor away from the place where the problem can be solved.

bad power supply or power supply has been aging

numerous no-name computer components used in power supply work, the substances used are quite poor, could accessible guide to poor or the computer's power supply capability can not reserve up the circuit, When the system is engaged, the display screen will appear in particular the phenomenon of jitter. Begin to age the computer when the power supply, are likely to cause the same problem.

monitor speakers placed too close to

enough away from the speaker's attractive field effect will mediate with the normal operation of the monitall but that the display screen generated string of color, such as jitter and magnetic interference.

virus trouble

some computer viruses will disunite the display, such as: the character upside down, quake the screen, graphics, flip display. Screen jitter everywhere online script, is ample to make you push in after the first huge as an ox.



wrong graphics card graphics card re-inserted after the failure obtain precluded.

WIN95/98 system caused

after the write store as is for this reason that in the Control Panel - System - Performance - File System - Troubleshooting disable all drives in the write-cache, let the problem to be solved.

power supply percolate capacitor damage

open the case, if you see the power filter capacitor (on the board that heads the largest capacitance) at the top of muster, then it shows bad capacitor, the screen jitter caused by power failure. After the change of capacitance, you can solve the problem.
a common fault recorder
: Installation can not start the computer after burner

First off the computer power supply, check the IDE cable to open the case cover is fully inserted, and to ensure that the access PIN-1 Pin position is properly connected. If the writer shared with other IDE devices one IDE cable, ensure that two devices can not be set to SL

Troubleshooting II: successful use of analog recording, the actual recording but failed

recorder catered by the
are identical, that is, problems and recorder laser power and disc read-write head matches and so on. In outlook of this, that write speed machine, it is recommended 2X the following;
2. to replace another brand of vacant disc to burn operation. There's another reason why this phenomenon is the phenomenon of laser power attenuation caused by read-write head, and if you use the same mark of disc burning, the first time were normal, it is likely related to power loss and the head can be sent to the relevant vendor maintenance.

Fault Three: Can not copy the game CD

some large commercial software or game software, in the creation process, the protection of the CD disc to do so during the process of copying CD-ROM in, there will not be copied, resulting in the burning process the error occurred, or not work after copying to happen.

Fault IV: Burning the CD music can not play properly

not all of the audio equipment can be properly read CD-R discs, most can not read normal CD drive CD-RW disc's contents, so it is best not to use the CD burner to burn music. In addition, you also need to note that burn music CD, CD-DA must obey with the file format.

five common faults: the process of burning software to burn the disc, sometimes Usually in the burning process, data needs to be burned off by the IDE hard disk interface by
sent to the host, and then transmitted via the IDE interface to the recorder in the cache (BufferMemory), the last writer in the store in
BufferMemory data for recording message onto CD-R or CD-RW discs, these operations must be consecutive, must not interrupt, if any one part of a problem, will not work cause the recorder to write data, and a buffer due out in error, and then to disc scrapped. The solution is, before the burning need to close some memory-resident procedures, such as turn off CD automatic insert notification, disable antivirus software, Window task management and task scheduler and the screen saver and more.

Troubleshooting Six: CD burning process, they would often flame burn failed

improve the success rate of the need to maintain a simple system environment, ie turn off the background resident program, it is best to prepare one for the recording system Dedicated hard drive, specifically related to software installation and burning. In the burning process, the better the data stored on the hard drive first, made into The burning process in order to ensure smooth data convey, you need to arrange out debris often hard to avoid not work because the file transmit, the error interruption caused by the burning, you can execute . In addition, in the burning process, do not run other programs, even the mouse and keyboard is not going to touch lightly. Best not to burn the use of computer and other computer networking, in the burning process, if the system administrator to send messages to the machine, will affect the burn effect, In addition, the LAN, do not use resource sharing, if the burning process,n real estate tax urban land use tax study notes, other users to read the local hard disk, can cause interruptions or failure of the recording. In addition, the recorder should note that the heat exhaustion problem, good heat exhaustion will give a stable burner work environment, if for a continuous recorder, burner heat is too high, you can turn off the computer, such as the temperature continues to decrease at a later burning. Built-in recorder for the best in the chassis with surplus cooling fan. External recording privileged attention to dust, moisture, so as to avoid laser to read and write is not normal.

seven common faults: use EasyCDPro recording the directory name in Chinese is not recognized in the use of EasyCDPro burn

Chinese file label, they can select the option in the file name Romeo, can support up to 128 bit file
name, that is 64 characters in the file name of the. In addition, WinonCD, Nero, DirectCD2.x so the Chinese can be a good support long file names,
