Computer Closes Programs

[duffguy]

So one day im on my office computer and do the regular thing ( browse on Firefox or play a game or two ) and i turn it off. The next morning i try to play some World of Warcraft and in about 10 min in the game i get a Critical error message for World of Warcraft. So i decide to go on Firefox and look up the error and about 10 min later i get that windows error that says Firefox encountered a serious problem and the SEND or DON'T SEND option. I restart my computer and try it again and i get the same error. This also goes for any of my games or browsers i try to use which close with a error message in 10 min or my computer just restarts. I tried Disk Defragment, i tried using windows system restore, and my firewall nor my AVG detect a virus. Please help me with this problem.

System Specs:
Windows XP Home Edition
ATI 9550 256mb AGP
MSI (7060) Motherboard

I also tried using different Anti-Virus programs also spyware programs like Ad-Aware

sounds like the registry is corrupt or the system is overheating when playing games. And what the heck are you doing playing games at WORK!

I doubt it is a virus. Work computers are not designed for gaming. Gaming is very taxing - especially something like WOW.
