just bought XFX RX480, installed it and installed a fresh new 16.8.3 update driver after using DDU to remove any old files.
the system recognize the card and everything is great until i load games.
- For example, Deus Ex Mankind divided
the menu is up and when i start the game - BOOM the screen goes to sleep as if i turned it off.
The computer still runnin' and sometimes there is still a sound from the game.
the problem applies to all of my games such as the witcher 3 and the division.
also when i run 3dmark tests.
