I have sapphire r9 280x vaporx gpu. Default 1070, 1550 clock and memory speed. I didn't touch voltage and overclocked 1150, 1600 after 5- 6 try, I am getting wierd screens. I turned clock speeds to defaults, reinstall ati drivers. Now my gpu and cpu at default but still getting these screens while playing games or wathcing videos. It appears randomly not everytime. You can see these screens below.
Some times screen totaly turns green, blue or black.
Anyway how can I fix these problems ? Thank you ...
