[SOLVED] Installed a new GPU, but now getting random black screens?

[SmoothieHotdog]

Just got this GPU installed yesterday, runs fine until I run more intensive stuff, like games, then i get black screens. It doesen't happen immediately, sometimes it takes a few minutes to happen but sometimes hours.

ASUS ROG STRIX B550A
AMD RYZEN 7 3800X
GIGABYTE 3080 OC Vision Rev 2.0
Corsair Vengance RGB Pro 16x2 3000 mHz
EVGA SuperNOVA 850 P2, 80+ PLATINUM 850W

Methods I tried:
Reinstalling GPU
Reinstalling graphics driver
Changing PSU wire

If you get black screens and never recover, it could be a cooling issue.

Depending on how demanding a game is, the load on your card will vary, and so will the speed at which you'll be reaching 80C+ temperatures. Ideally you don't want your components to go above 70C if you want them to last. 80C is way too high, and your GPU should never go above that. If it does, then at a certain point your GPU can't keep up and games crash, which is what you might be experiencing here.

My card barely uses its integrated fans by default. Even when it reached critical temps the fans never worked at full speed. I had to go into the Radeon Software app to manually change how hard I want the fans to work at given temperatures, and I haven't gone above 55C since despite playing games that overheated my card above 80C to the point of crashing before. I'm aware your card runs off NVIDIA software, and I don't have first-hand experience tuning fans with their software, but:

If you're using a water cooler, monitor your components' temps nonetheless, see what they look like when you play. What are your performance metrics at the time of those black screens? Stuff like that should help point to the problem.
