Windows 10: 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 *Sad 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!

PC Randomly Shuts Down While Gaming

So basically my PC works fine after wiping out the hard drive previously. I even have the LATEST drivers installed for my NVIDIA GeoForce graphics card. Unfortunately that is until I start gaming. Any game I play begins to work like a charm. But only for
about 10-15 minutes before SHUTTING DOWN MY PC. I'm highly annoyed because this has just been one thing after another. Yes I use the WINDOWS 10 operation system. If anyone at all has a solution I would greatly appreciate the assistance. I suspect it could
be the McAfee software interfering but I'm not entirely sure. I really just wish to have my PC absolutely functional once again.

I would seriously appreciate any assistance you can give me to solve my issue.

Thank you.
