BSOD keeps appearing during startup

[Jal926]

I need help, last night i have trouble on my usb drivers, and i assumed if i install windows update, it wll solve the problem. During the installation, i stopped it for i will sleep. The morning after, i opened my laptop, but during the startup (Starting windows) blue screen will appear. And then it will restart and, same events occur. Please, i need help. I dont want to harm my files.

Blue screen shows:
A problem has been detected and windows has been shut down to prevent damage on your computer.
PROCESS_INITIALIZATION_FAILED
If this is the first time you've ssen this stop error screen,
Restart your computer. If this screen appears again follow these steps.
(and so on)
Technical information:
*** STOP: 0x0000006B (0x0000000000000000, 0x0000000000000000, 0x0000000000000000)

I've tried tapping F8, and start using safe mode but blue screen just keeps appearing.
And for your info, i don't have any discs for "repair" menu.

I'm using Sony Vaio, E series, VPCEG38FG
windows 7 home premium 64bit
Intel core i5-2450M processor 2.50 Ghz with turbo boost up to 3.10ghz
Menory 4gb / hard disk drive 500 GB.

Thanks!
