I recently built a new rig with the below spec
The machine works okay until you run a high demanding game (Warzone, Cold War and Apex tested so far)
It will sit on the main menu of these games for a few seconds before the PC restarts
I have managed to run a less demanding game for over an hour (Company of Heroes 2 and Rome 2 Total WAR) without any issues
I ran a lot of CPU and GPU stress tests such as Heavy Load, Furmark, Cinebench and 3dmark - which have brought up zero issues
PC Spec -
Ryzen 7 5800x
Asus Prime x570-P
Corsair CMK8GX4M1D3000C16 Vengeance LPX 8GB RAM
Nvidia RTX 2070
Crucial M.2 drive 1TB
EVGA 600w
Any help would be greatly appreciated, thanks
