I just built a new pc, but I am having trouble with my motherboard detecting my graphics card. My mobo says that the pcie slot it is in is not occupied and my monitor shows nothing when I power on the system. However, the fan and led on the card start when I turn on the system so I assume power isn't an issue. I tried a different card in the same slot and my motherboard said the slot was occupied and the monitor showed the bios screen. I am at a loss. Is the gpu damaged somehow?
