When it occurs post as much of the information on the blue stop screen (bsod) as possible.
It may be able to point us to the fix.
But actually, the best thing to do is to use your Windows System Restore to reset your system state to a previous working condition as it was before you downloaded the program that made it crash.
go to start/programs/accessories/system tools/Windows System Restore
Pick a date in bold from before you loaded the driver that has caused the crash.
Follow directions on-screen
If you have done any Windows Updates or updated your AV program since that date you will have to redownload the updates.
That should cure the problem if your system was running properly before the crash.
After your system boots properly I suggest you reboot and do the following web-based scan using Internet Explorer only:
Windows One Care Free Scan
Go to Windows Live Onecare Free Scan
It will say "Get a free PC safety scan"http://safety.live.com/site/en-us/default.htm
Make sure you click "Full Service Scan"
in the middle of the page and not the "Try It Now Free" on the right side.
Allow it to download an Active X component.
Choose "Complete Scan" in the window that opens
Do not click on anything else that offers you a free trial or to sign up if you live in the US.
Allow it to scan - it may take quite, maybe two hours or so depending on how big your hard drive is and how fragmented your registry and drive are.
