I recently bought a XFX Radeon R7770 Black Edition card and it will not work properly. If i hook a HDMI to it from my monitor it will give it signal. The fans also spin on the card. The main problem is i cannot run games! If i open up a game it is says im missing shader or DirectX. Also in device manager it will not show up as a device. Lastly i have been told to install drivers but it honestly gets errors everytime. I have cleaned my drivers and re-installed CCC. Still it will not install. Please anybody very knowledgeable help!
