If you're able to get into Windows - please provide this info: http://windows7forums.com/blue-screen-death-bsod/38837-how-ask-help-bsod-problem.html

If not, then please hit F8 just before the Windows Splash Screen shows up
then scroll down to the "Disable automatic restart on system failure" and select it by pressing Enter.
then boot again and see what the screen says.
Here's the information that we need from it (the stuff annotated in RED):


There are 2 common reasons for failure to install a Service Pack:
- outdated drivers
- malware

Please update ALL drivers from the manufacturer's website
Then scan for malware with a couple of these free scans: Free Online AntiMalware Resources
