I have an AMD R9 200 Series video card on my PC. I was having problems with the computer not waking up when I came back to it. It was traced to a defective video card which was replaced. It was still having q problem until I manually uninstalled the video driver and then installed the latest one again. The problem then disappeared. Now I have upgraded to Windows 10 and the problem is back. I have tried manually uninstalling the driver and updating it with the latest recommended driver downloaded from AMD but the problem persists. Anyone having the same problem or a suggested solution?
