Office Enterprise 2007 Product Key Win7 not bootin

Hi there,Buy Office Professional Plus 2010,Windows 7 Key BA strikes Q&A how your flight is affected -Times Online.html,
I possess a Sony Viao SB19GG (the Raid 0 SSD model).
It has Win7 Skilled on it.
It is new i.e. 3 days previous. I ran Win7 updates initally and all was great. Yesterday I up to date through the updates and it appears now the Viao is not going to boot. Basically,Office Enterprise 2007 Product Key, the Win7 logo display comes up and hangs.
When I boot into safe mode with networking it'll boot up. I then restart the pc and it boots straight in.
What may be the achievable cause and therefore are there any instruments I could run to locate the issue whatsoever?

System restore from Protected Mode.
Install Windows Updates 1 by a single to see if there is 1 which is borking the program.

Will a system restore delete my data installed because the previous restore?
