Hello, I've recently replaced my gtx 660 with an R9 290 and my motherboard is stuck when trying to boot up. I have unistalled all nVidia drivers and registries. My computer will load if the HDMI is put into the mobo. The driver CD that came with the card will not work unless the card is plugged into the system and detected. Specs -> http://pcpartpicker.com/p/6Q96qs . Any help would be greatly appreciated!
Update: The card lights up and the fans spin when plugged into the PCIE slot. And yes, the power is connected.
