So, I am trying to figure out why my motherboard isn't reading my GPU. I have gone into the BIOs and switched to the PCI Express on the Northbridge. Everything I have done has failed. I switched out Hmdi cords at first then I booted the computer without the card installed and it booted to the BIOs. Now everytime I try to use the card it won't load anything on the moniter. I have two different cards. I have the GTX 650 ti boost and GTX 670 FTW. Tried both and both have the same outcome. I am using a ASrock mini itx board with 16g RAM. I also have no OS installed.
