I just built my first gaming rig and am working out the kinks. The graphics card I installed was a AMD Radeon HD 7950. Everything in the computer works but its like the graphics card isn't even there. The fans spin, and the monitor is connected to it via HDMI graphics card. I am utterly confused as to how the computer can display everything through the graphics card but not recognize that the graphics card is even there! Please help!
