hey ok so i've been haveing this problem for a while where my computer will just randomly shut off. It started and only happened once while i was playing Call of Duty 2. I had been playing that game for almost 3 months with no problems till then. Then it spread to the computer just shutting down randomly when doing nothing. I checked the temps and everything was ok but the GPU was up to 70 degrees C, is this to hot? The GPU is a Nvidia GT 120. If it is to hot is this why my system will shut down?
