XFX RX 580 8GB Screen Flickering and Message "Default Radeon WattMan settings has been restored due to unexpected system failure"

Question asked by daste on Aug 30, 2020

Hi, I recently got an XFX RX 580 8GB version, and every time I play games, the screen becomes black, and most of the time the monitor says "No Signal", and after restarting AMD Software says "Default Radeon WattMan Settings has been restored due to unexpected system failure."

tho the CPU fans are still spinning, but sometimes when it black screens, it comes back without it needing to restart but the graphics are messed up. There are some pink/white cubes, i caught one of them on camera, but there are many more. What do I do? 

Btw I bought it as used, and it doesn't have a warranty.
