I'm getting either a crash to desktop on startup with '0x887A0007:DXGI_ERROR_DEVICE_RESET' or a black screen and a hang with the fans on max. Only happens when DX12 is enabled. Tried swapping in a a 290x that I had installed until recently and it works with DX12 enabled.
I've done the clean driver install dance. Used DDU, ran 'sfc /SCANNOW' and DISM /Online /Cleanup-Image /RestoreHealth.
I tried disabling the antivirus and getting rid of the system tray clutter.
I verified the system is stable with Prime95, Kombustor and Memtest86.
I updated to the latest motherboard BIOS.
16GB Corsair Vengeance RAM (4x4, purchased as a kit)
Asus Z97 Pro WiFi ac Motherboard (Bios 5303)
PowerColor Red Dragon Vega 56 (upgraded from Asus DCUIIOC 290x)
EVGA SuperNOVA 1200 watt Power Supply
I'm on a clean install of Adrenalin 19.2.1.
