I built a new pc today which includes a ryzen 7 1700, Vega 64, msi gaming plus x370, 16gb of ram, and an 850 watt psu. I've set it all up and when I boot it with the Vega 64 I get a black screen. The card turns on and the fan starts moving but nothing ever comes on screen. I put my gtx 1060 in and it starts up. I've never built a pc that didn't have onboard video so I'm not sure how to put the drivers on if that's what's causing it to do nothing.
