So my Sapphire Radeon HD 7970 GHz Edition Vapor-X isn't showing up on my cpu at all. Ive looked in device manager. I have tried plugging in my monitor to the graphics card, not the mobo, but its just a black screen. i also have it connected to the power supply and I have made sure that it is perfectly in the mobo. I have no idea why it is not working and i am desperite. I just spend 1.5k on this computer and i cant get the graphics card to work D:
