I updated to a rx6950xt gpu from my old 1080ti turbo in January. It was working flawlessly until the beginning of this month where I will consistently get random game crashes and often crashing my whole system. When it does crash the system it’s not a normal bsod, but one where it appears to glitch on the screen(so I’m unable to get the error code for the bsod)and doesn’t shut down until I do it manually.I originally had a EVGA 850 psu but upgraded to a Corsair 1000 assuming it might be a psu issue, but it didn’t help. It’s too late to return the gpu and now I’m wishing I had just went with the 4070ti. I’ve updated my drivers for it and I wasn’t having any of these issues with the old gpu. I’ve also reseated RAM and gpu as well as checking cable connections. Any ideas? Do you think this is a hardware, software, or BIOS setting issues
