I am massively disappointed having bought a decent gaming rig with your R9 390 card. I have the up to date drivers (currently 15.7.1) I'm using windows 7 -64. I have a new intel i5 -firstname.lastname@example.orgGhz, 16 GB ram.
I have trawled forums to get these games to work ( I know Rome 2 is generally buggy so I tried the Witcher 3) I can't have more than 10 minutes play before a complete crash to black screen. Audio still plays, but I have to CTRL-ALT-DEL my way out, if I restart the game, within minutes it blue screens my computer.
I have tried turning on and off settings in graphics options, lower resolutions, and still nothing works. This really sucks. It's my first AMD card... massive let down. Please help.
