Windows 10: Computer Random shuts down while gaming

    Computer Randomly shuts down while gaming

    I am at a loss on this issue I'm having. I can't tell if this is software or hardware.

    About two weeks ago, my home built rig randomly started doing two things it's never done before.

    Firstly, while playing various games, it just completely powers down. There's no warning or anything. On some of those shut downs, it even tries to power back on but then dies again. I have to then unplug the power cable and push the power on button to get it to boot up again.

    The second symptom (I don't know if they're related) is, I will be running locked 60 FPS and my frames will drop to 0 for one or two seconds and then they go straight back up to 60.

    When this first started happening I did a bunch of testing, looked at temperatures and what not.

    All of my temps for my CPU average around 50 C. On occasion they get up to 60. I don't think it's my CPU. I also did a few tests for my CPU and it appears there's no drop in voltage. My graphics card does get a little hot, high 70s but I don't know if GPU overheating would cause random crashes.

    The next thing I thought was....failing PSU? So I just replaced my 4 year old PSU and....I still get frame drops BUT I have not had a random shut down now.

    I did a full driver update as well, cleaned up any potential viruses (nothing found) and ran disk checks. All good.

    So now I'm more confused Maybe the two symptoms are unrelated? Or maybe my old PSU was failing and the random frame drops caused a drop in voltage to the main board?

    Any help would be greatly appreciated!
