I have bought a used XFX RX 580 4GB GPU. The card looks good generally but problem is when i start PC i can see some strange green screen as in screenshots below. Also same problem is come when OS is loaded without drivers as you can see on screenshot. When I install latest AMD drivers all looks normal, temp is good i have tested card with all benchmarks and no problems at all,, but the problem with the green screen while booting the computer is still there until Windows loads the drivers. Any idea why green screen is there while PC is booting and what can be problem?
