I havn't BSOD'd in a long long time but many things can cause that. What OS are you using? How much RAM? How many apps open at once? You might have been using to many apps at once with low system memory, that will do it every time. If your using Windows ME then well, just that alone is your problem.

If it repeats itself, keep note of what you had running at the time. Odds are it's nothing to worry about unless like I said it happens repeatedly.

There are several known viruses that cause this to happen. Are your virus signatures up-to-date? Are you running a firewall?

Never known a virus to cause it under WinMe/98/95.

Various things can cause system instability and random shutdowns. A few that come to mind are faulty power supply, trojans, too many temp files. Here's a little "basic maintenance checklist" that should be done regularly. It might help fix the problem you're having:

-- Delete all temp files (c:\windows\temp\*.tmp, or on XP C:\Documents and Settings\username\Local Settings\Temp)

-- Delete temporary internet files (c:\windows\temporary internet files\*.*, or on XP C:\Documents and Settings\username\Local Settings\Temporary Internet Files)

-- If you use I.E., click on Tools, Internet Options, Delete Files, select "delete all off-line content", click OK

-- Click on Start, Programs, Accessories, Systems Tools, Disk Cleanup

-- Download AdAware, check for updates, run it and remove whatever it finds

-- Download Diskeeper and defrag

-- Download, update and turn on SpywareBlaster and SpywareGuard.
