I am noticing RANDOM problems with my PC. When I play World of Warcraft, It will half of the time Crash saying that there is a missing file. Sometimes, other random programs will crash(MSN, Firefox, anything else) will also crash. Now I am using Norton 2007, and I also scanned on Housecall, and they both said that my PC is all good. I also use Spybot, Adaware, CCleaner to grab EVERYTHING else.

What could be the problem? Any other ideas on what to do?The exact error messages would be necessary to advise. Has it always been this way? If not, what has changed?

You could check your RAM with the free DOWNLOAD at www.memtest86.com

Then check the hard drive with the free diagnostics from the appropriate hard drive maker's site.The error messages im getting is the so and so program is non responsind and has to be closed, do u want to send Microsoft the error data so we can help u,

its been like this for a little while now, maybe a few months
The specific error messages are very important including the missing file. What if you UNINSTALL and reinstall the game?

How long has this Windows INSTALLATION been loaded? What version? What service pack?
