PC keeps crashing when I try to play most games and I can't figure out why

All the errors seem memory related. It will also crash to a black screen but it always restarts before I can get a good look at the error message.

I've reinstalled windows, I've tested both the RAM and all the Hard drives separately, I've tried "sfc /scannow" and "Windows Memory Diagnostic" but none of them have found any issue. I've run every test google has suggested but I can't remember which ones. None of them fixed my issue or gave me any indication that something is wrong.
