Question This one is weird! Please help crashing problems!

Oct 19, 2019
Okay, so I'm just gonna go out and say this is my first PC build ever so please take that into account!
The problem I've been having is that Since I built my computer it has had a problem with restarting randomly. I'll log on and it will immediately restart and keep restarting every 2-5 mins untill I boot up a game.

When it restarts There is no blue screen. No error codes. It's like if I unplugged it and plugged it back in.

y computer for some reason or another will not restart if I am running a game like valorant. So I've resorted to having valorant running in the background whenever I'm using my computer.

This is still bearable because I love valorant, but I would like to play other games and for some reason my computer doesn't restart only when Val is running.

MB: MPGz390 gaming plus
Ram: Corsair vengeance PRO 16x2
Processor: I7
PSU: 750W
GPU: 1660Ti
I have already replaced the ram and switched spots.
Ive checked for overheating and everything is running cool.

Like I said this is my first ever build. So I'm at a loss for what to do. And everytime I try to look up my issue it's the opposite (computer crashes when playing).
