Hi all, I've got a weird one.

Just got this r9 390 this week. When i turn my computer on for the first time in a day, it will work fine for ~10 mins before i get some screen flickering and then it freezes and I have to hard reboot. Once I do this, the computer runs just fine. I've tried the latest drivers (16.2.1 hotfix) as well as the previous stable drivers (15.12).

System specs:

Windows 10 64bit,

Intel i5-3350P @3.10GHz

XFX r9 390 8gb vram (although dxdiag lists "approx total memory: 12243MB")

8GB ram

Sharp 1080p tv via HDMI


Is this card toast? I'm pretty close to getting on the horn to newegg or xfx for a replacement.
