EVGA GTX 950 SC+ (works but for parts - please read!!!)

I had this for a while, and it still seems to work. I boots and does all the normal things a graphic card is supposed to. HOWEVER, I am unable to load Windows driver on it. It will only load a generic driver (which does very little in terms of changing configurations and/or resolutions). SO I am selling this for parts. Perhaps you can figure this out. Please ask if any question before buying. Thanks.
