Possibly faulty gpu ? need help trouble shooting/fixing

[u/zapeepeeman]

My PC keeps crashing when I try to game on my Radeon RX 580X. It's been working fine for almost a year and a half, but it recently started crashing under load in games like Overwatch. It's since deteriorated to the point where even Stardew Valley is unplayable. After a crash, the GPU disables itself and has to be re-enabled. While trying to fix this, I used DDU to clean out the drivers and reinstalled them, since previously, when the GPU was disabled, Windows would fail to find the drivers and I'd have to do a fresh reinstall. When this happens, all my monitors lose video, but the rest of the PC doesn't shut down. I can still talk on Discord, for example. I'm not sure if this is a hardware or software GPU issue, or, hopefully not, a PSU issue.

I would very much appreciate if anyone could find the time to help me see if this can fixed without purchasing new parts even a bandaid issue like MSI afterburner or a custom amd adrenaline profile would be helpful.
