I have a b660m mortar and a i5-12600k with ddr5 5600mhz ram running at 4800mhz. I also have a 2070 super and 750w power supply that works. When I stress test everything with aida64 I have no issues but sometimes when I am playing games like cyberpunk or elden ring my pc completely restarts without warning. I have reseated the ram, cpu, gpu and cleaned everything as I did that. I have reinstalled windows and all graphics drivers. At this point I’m totally lost and just want a functioning pc. Does anyone have any idea what the problem could be?
