Problem

Hello everyone! So I’ve built my second PC and have come across numerous problems including all my games crashing at random intervals and then going to desktop with no error, sending the audio into a loop and then going to the desktop with no error message, I also received a few bsods during initial setup but they seemed to have subsided for now. I also noticed that when in game my cpu usage was pretty low but my gpu usage was stuck at 99% I have no idea if that has anything to do with it but I just thought it might help. 
 

What I’ve Done 

Replaced GPU, PSU, and RAM

Reinstalled Windows (x5)

Ran SFC, CHKDSK, 
Updated all drivers including BIOS

Updated windows

Have you ran DDU (Display Driver Unistaller) and re-done the GPU drivers?

 

Do you know what the error codes were when you got the BSODs?

 

GPU at 99% during load is fine, just means the GPU is being utilised  fully.

So you're only getting crashes/BSoD's during gaming?  Or is it under any load?  Have you been monitoring temps aswell as usage?

Yes I am only getting crashes during gaming, benchmarks will go for a few hours before crashing. Monitoring temps during Adia64 gave me temps in the mid 70s. The computer works fine during normal use like web surfing and video watching as far as I can tell.

So yes I did run ddu and reinstall graphics drivers and it didn’t seem to help. I can’t really recall what the bsods were but I remember irql not less than or equal to, reference by pointer, and kernel security check failure.
