I got a gtx 970 founders, ryzen 5 1400, and an msi b350m gaming pro motherboard. When I put them all together I don't get a post. The screen stays black but all the fans spin. But when I plug any of my other gpu's in every thing works fine. The main problem is the gtx 970 works In my old rig. Just plugged it in to test it. I'm so confused plz help.
