New Desktop Randomly Restarts (Custom Build)

[evale]

My desktop will restart without any noticeable reasons for each. Has restarted right after boot and 3 hours into running. Started happening multiple times a day.
I do not get a blue screen. I dont get a sound or alert. It simply shuts off and restarts within 3 seconds. I have looked through dozens of forums and similar experiences to try to find a solution. Without the ability to start swapping out pieces to see if its a hardware issue, I wanted to get another opinion encase im missing something.

1) I have checked the temps several times. Nothing is overheating.
2) Was happening before I installed the GPU.
3) Ran a stress test on RAM using Prime95 (passed)

Have done some small things here and there. I would like any advice. Anything to avoid having to replace my hardware. At this point, I assume that it is probably my PSU failing for whatever reason. I have only had it 2 years and never come close to maxing it out.

While trying to play PUBG I noticed a pattern. I would start up the game, and before it was done loading to the menu, the desktop would restart, it did this twice before it actually let me play the game, and then restarted again the next time I went to load the game.

I'm not 100% clear from your post, but is it only doing it on pubg or is it completely random also?

It is completely random, but for some reason it was also restarting 3/4 times I tried to load a semi intensive game

It definitely does sound like a psu issue, if it was happening only during pubg i was gonna say i had the same problem with all steam games, ended up having to do a clean install of windows and it fixed my problem. What you are describing does sound like a psu issue though, your psu has a pretty good warranty i would call evga and start the rma process. I'm assuming you dont have a spare psu laying around that you could swap it out with, or you would have already tried that.

Yeah, I dont have a spare at the moment. And since this was a new build, I did a fresh OS install from a flashdrive. Ill try buying a new PSU, if the problems persist, ill try to return it and maybe take in the whole thing to a nearby store to get it troubleshoot

 

[Paul NZ]

Did you assemble it? If you did, did you put the standoffs in before the mobo?

 

[evale]

Yeah. I placed in the mobo to figure out the where they went and then put them in.
