But the issues come when I try and install any AMD Sapphire Nitro RX 480 drivers onto the system, then it comes up with errors like video_source not found and other error codes. I've build my AMD computer system, all hardware works inside the computer even the GPU it self works. Recently I've been trying to get this Sapphire Nitro RX 480 4GB GPU card working but will not work! I think I may know the problem but not sure on how to solve it.
