Windows 7 won't recognize the HD 7770 that I just installed(and updated the drivers) over my integrated graphics. When I plug in my display adapter to it nothing will show up on the screen. I had to update the drivers through a flash drive because I don't have an optical drive(thought the info might be pertinent). I went into my bios and I can't find any setting to disable the onboard graphics. I have an Asrock A88x BTC+ motherboard. Can anybody help me. I'd be happy to share more information where it is needed.
