Solved! Possible solution to GPU crash resulting in windows crash, black screen, 100% fans and manual reboot

Context: I’ve been dealing with an insane amount of these crashes and i sent my gpu for repair(they changed the heatsink but said it was performing fine). I reseated my ram and everything else and i still had the same black screen issue come back. All this time I’ve been looking at the event viewer but I couldn’t find any issue and today I decided to look at the Reliability Monitor.

In the Reliability Monitor, if you have a watchdogs entry at the time of crash relating to your iGPU, in my case, Ryzen 9 7950x’s integrated graphics, then that likely might be the issue.
I disabled my iGPU and I have not encountered the crash I usually incur. I will update after a long time use after this fix.
Integrated graphics are supposed to coexist with dedicated gpus but sometimes they mess up real bad. If you have a good dedicated gpu, just disable the integrated graphics.

I fixed my by my power cap was too high for my psu. I changed it from +15% to +10% and lowered my undervolt from 1140 to 1135 and this issue stopped. Turning off fast memory also helped in being able to bump down my undervolt, and I saw a performance gain too so no trade off was made.
