Question PC restarting by itself while gaming

My pc has been restarting for a couple of months now and I always suspected that my psu was the problem but despite replacing it yesterday along side my cpu it still continues to have issues. When it restarts theres no bsod, it just simply shutdowns -> black screen -> restarts back to normal. I've tried many things, my bios is updated to the latest version, used ddu and got latest graphics drivers, got all the latest chipset drivers, rechecked my psu coords multiple times. I've done many stress tests so it can't be the temps, cpu at 100% load is at around 65-70 while my gpu is at 80-85. Nothing is overclocked at the moment. My pc was previously connected to an extended cord but I have connected it to the outlet directly now. I'm using all the cables provided by the new psu. Crystaldiskinfo says my ssd is in good condition. There still a couple of things I could try like overclocking/undervolting, reinstalling windows, I saw someone suggest trying older versions of my graphics drivers and using wushowhide so windows doesnt interfere. I have a small suspicion its either my gpu or motherboard since it only happens while gaming. I would greatly appeciate some help or advice.

A system that reboots when taxed would usually indicate one of two issues;
1| Your system is overheating, i.e, thermal protection taking effect
2| Your PSU is incapable of powering the system when taxed

BIOS version for your motherboard? Try and use DDU to remove all GPU drivers, then manually reinstall with the latest GPU drivers sourced from AMD's support site, in an elevated command, i.e, Right click installer>Run as Administrator.

Nothing is overclocked at the moment.
Your ram is also at stock speeds? D.O.C.P disabled?

See if aiming a fan at the VRM area helps.

Bios version: 7C02v3H
Yep ram is at stock speeds, xmp and anything like that is disabled.
I'll try and do the ddu and running the installer as administrator right now.
