I have a GTX 770, it isn't listed in device manager, only my integrated card. I physically checked and it is secure. Also I plug my monitor from my main board into my graphics card (both dvi) and screen goes black/blank. Monitor works fine when connected to mainboard slot. Not sure if these are 2 problems or what. Please help.
