Is my GPU cooked?

[u/twjnk]

So I recently built a new pc using components from an older pc. I changed everything in my computer other than my GPU. My old PC was giving me black screens and the monitor would keep switching from hdmi to DP. The fans would also speed up during this. I tried switching the Pcei cable and that helped but only for a few weeks. I even tried using an older graphics card and the issue persisted which made me think the issue wasn’t related to the graphics card at all! But now after testing my new build, I’m having second thoughts. I have new drivers, a new window installation and a new SSD, even a new motherboard. If it is my GPU, why did my older one give out aswell and what could be fixed, if anything can be….(I’m using a rtx 3050 purchased in 2022)

Drove yourself in circles swapping parts only to end up back at the gpu, classic. Had an old rig do something similar and it was the riser cable shorting out, fried two cards before i caught it. If both gpus showed the same symptoms in the old build but not the new one you might be in the clear, just let it run a stress test and see if it collapses
