My gpu seems to have died... I get artifacts and lines on screen during cmos/bios and crashes just as the loading screen for windows comes on before it reaches login page.
Is it likely that my psu is the root of the issue? Its a be quiet dark power 600w but quite old I'd imagine from around 2012/13 maybe
I did however overclock the gpu but set it back to stock around 5-6 months before it died

I'm just wondering because if I buy a new gpu and it kills that one too Il be annoyed haha

My cpu has no integrated gfx and I don't have a spare/old gpu around to test

When loading cmos/bios all other stuff is white but vram voltage is yellow :(
