You can download EVEREST to see if the system is overheating. If the fans work, then the chances are that it's something else. Are you getting any error messages at all? If so; to get a better idea of what is going on, I would advise that you "disable" automatic restart so that a BSOD will appear on error... instead of a sudden restart. The BSOD should point you in the right direction by identifying a certain file, most likely a driver.

 

Well i got everst and everything seems to be normal, what leads me to belive it might be a driver. I also turned off the auto-restart .My roomate told me to install the game World Of Warcraft to test if it was still crashing. Now it crashes right when the game loads up.
