Hello everyone, 5 days ago i bought a new system with R9 390 Sapphire gpu. The problem is that i cannot install AMD Catalyst/AMD Display. When it reach, in the installer, the AMD Display, black screen and total freeze of my pc.I had at first Win 7, but this morning i installed Win 8, but the problem remains. In the Device Manager it shows me in Display adapters : Microsoft Basic Display Adapter. I even try to update through him but the same problem, in the middle of instaling poof, black screen and freeze. My PSU is a good one, Gold 80+ 750W so i dont think it from it , anyone have an idea, please, before i go crazy. Thank you.
