i have an amd 3870k with the stick cooler on it, and 2 weeks ago while playing battlefield 3 my pc shut off. I thought it was a issue with the game itself and re installed it, however the problem still persisted. And the same thing happened in arma 3. i stress tested my pc amd all the temps were fine except my cpu which got to 83 degrees Celsius then shutting off. My issue besides that is i haven't done anything to my cpu or heatsink and i have added 2 case fans to my pc.
my power supply is a cosair tx650 so i dont think its a power supply issue.
