Odd shut down problem

[Morg]

Doom shuts my pc down after a few seconds (like the power has been pulled). It's odd in that the pc can run all stress tests and not collapse (max temp 70). I've tried fallout 4 and it runs without problem. Is this just a doom problem or is the something else to check?

Quick bump in case anyone ever needs it. It was a driver conflict between nvidia and realtek audio. Only install the nvidia drivers you need.
