99% sure your GPU is on it's way out. Have another card to try? Friend who has a card you can try?
TINY chance it's the PSU, but I think you would be having other problems as well.
Get better quality tools, and don't over-tighten like a gorilla. I've done over 10,000 joycons/consoles/controllers. I've went through about 4 tri-wing screwdrivers and maybe 10 phillips head.
Runs amazing on ryujinx. Already 10 hours in, no crashes, no sound issues, no texture issues. 5950x & 3090, 4k resolution, 60fps 99% of the time, save for a tiny stutter when doors open. Looks amazing on my 77" OLED.
Chris Pratt is eh, so many better people could have voiced mario. I love IASIP, but I don't want to hear "huffing paint" Charlie as Luigi. Another one where they could have gotten someone better with voice acting.
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
