For the past few weeks I have been seeking an answer to my delema: what the hell is wrong with my computer? Whenever I play a game (xcom:enemy unknow or civ 5) my screen goes black and the system restarts. Im assuming that it is a gpu overheat but the issue is that my temp doesn't go above 72 C. In an attempt to keep it running I have even taken the side off of the case and pointed a fan at it but still it crashes.
it can be three point of failure. a bad stick of ram that has a bad bit. the power supply under hard load is not holding the system up. the mb has a volatge reg issue that not holding the mb on under load or heat. if you have another power supply or can poick up a spare i would try the power supply first.
