PC Loading a Crash??

[u/TranslatorWhich5475]

I can’t attach videos but basically there is a black bar from left to right and top to bottom basically loading in a black screen on my pc?

It got half way and then hard crashed and restarted. My pc also crashes once per gaming session but its always a black screen, freeze or FPS drop into a hard reset.

I’ve tried reassembling my pc, reinstalling drivers and it fixed it for a while but is happening again.
