Question Pc crashes and fans get loud

[Summie]

Hello,
About a month ago this issue first started and has been occurring more frequently. When playing games, sometimes my monitor will go all black, and my GPU fans will get extremely loud. I'm still able to hear audio but if I'm in a discord call people wont hear me and the only way to fix it is to reboot. So far I've monitored my temps and nothing has been out of the ordinary, and I've also ran some stress tests which didn't cause a crash. At this point it's occurring a few times a night and I'm not really sure how to go forward with figuring out the problem.

Specs:
CPU - Intel Core i9-23900KF
GPU - NVIDIA GeForce RTX 2080 10GB
RAM - Corsair Dominator 32GB (16GB x 2) DDR5 5600MHz
PSU - 1000 Watt NZXT C1000 80 PLUS Gold
MOBO - ASUS PRIME Z690-P

I measured my GPU hotspot when it last crashed and it runs about 20C higher than the GPU temp but it was only about 95C when it happened so I'm not sure if that was the cause.

Two things Is the GPU dust free? If you blow it out don't let the fans spin!

Open the side panel and leave off and just as a test put a box fan blowing into the PC.

Than use computer like usual, do all of your regular habits. Go play those games that crash the system.

Later we will know if it's still crashing while gaming or the fan keeps it from crashing or not.

No crash = heat problem

Still crashing than we dig deeper.
