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).
Windows 10 64bit,
Intel i5-3350P @3.10GHz
XFX r9 390 8gb vram (although dxdiag lists "approx total memory: 12243MB")
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.
