ok, my pc keeps crashing during games, usually after a couple of minutes. i have the latest drivers and i even got the graphics card i had replaced. (i had two months of no problems before all of this) I replaced the motherboard just before all of this started happening and ive tried two different motherboards since. So the motherboard, graphics card and its drivers are all not the problem. Which leads me to suspect that the processor could be overheating and cutting out to stop it from being damaged. is this a possibility, since i had to take the processor out etc. maybe the thermopaste stuff is not making a good enough connection between the processor and the heatsink. What do you think?
