I've a problem - My PC reboots itself randomly during games. Not all games though, only some - ie Dawn of War II, Fear 2, Portal & Company of Heroes all run fine, no problems; whereas Starcraft 2, Half Life 2, Alien Swarm, Crysis, AVP, and bizarrely winamps visualiser, all cause the machine to reboot, at differing times - Most last for a minimum of 5 minutes before the reboot, some will run for half an hour or more before rebooting.
Really at a loss.
