Installing drivers for the RX480 results in the signal to the monitor dropping and the screen goes black. Windows is still working in the background, managed to shut the machine down. Trying to boot into windows with the RX480 and drivers installed leads to no signal being detected from monitor.
Without drivers - works fine, booting into safe mode I can also see the RX480 is detected, integrated graphics are not being used.
I tried out the graphics card first with my old machine and I couldn't resolve the problem, hoped that maybe the problem would go away with a new rig, new hard drive, new mobo, everything - no luck, tried uninstalling and reinstalling drivers several times.
