I just got this card this week. As the title states, the first time I turn the computer on each day, it will start flickering after about 10 mins, and then freeze, forcing a hard reboot. Once I do this, the computer runs fine. I've tried upgrading to the latest hotfix drivers, as well as downgrading to the previous stable drivers. No luck.
Windows 10 64bit
i5-3350P @ 3.10GHz
xfx r9 390 8GB vram
dxdiag actually lists the "approx total memory: 12243MB" in the display tab, which is wierd.
Can I get some help, or should I just try to get the card replaced?
