Hi, I have a Gateway DX4860-UB33P computer and I just bought an EVGA GeForce GTX 660 SuperClocked 2GB. When I put the graphics card into my computer, I get no visual whatsoever. When I plug my HDMI cable into the motherboard, I still get no visual. There is no PCIe option in my BIOS to set the GPU to show a visual first. How can I fix this?
