Hello, Just a slight problem I've got that I thought someone here may be kind enough to assist me with; I've bought a G450 quad PCI, with the objective of course being to hook up 4 screens to one card. However, when I install it in my NF4 motherboard, it simply doesn't get past the POST screen. The motherboard has 2 PCI-e x16 slots, for SLI purposes, so it would seem like a good idea to disable the PCI-e slots. The only option I can find in the bios is to select PCI as the initial display device, but that doesn't fix the problem. I wouldn't have thought the card would be incompatible with the motherboard, but then I'm no expert. Any advice appreciated. Thank you.
