I'm having a problem, I bought a evga gtx 970, everything was fine till few days later when I try playing bo3 it loads it up but once i was on the loading screen, turns off and restarts. So I maybe taught the gpu was the problem, I take out the 970 out and put my old gtx 570 to see what happens, it runs the game for about an hour then shuts off and restarts. Checked the temps of both gpu and they're fine. As soon as my computer needs the gpu it turns off. I have an atx 850w power supply. Maybe nothing but I can load up bo3 on the lowest resolution with the lowest quality and it runs.
