Have you tried rebooting your computer? Could be some sort of memory leak or something

Are your steam ports open? Also turn of any running programs like AIM, MSN, Limewire, Utorrent and so on.

Xfire is also a big memory user (it eats up 40 FPS on my 8800GT)

Overheat maybe?

Use a utility like speedfan to check your temperatures, especially if you have to wait a while before your pc is stable after a crash.

The pc itself has the issue? Do you see a blue screen before the restart or is it just a straight restart?

maybe you don't have enough memory?

Overheating, perhaps?
