I purchased a new Gigabyte GA-K8NPRO-SLI motherboard with new components to build a new system. The only part that I am reusing is my video card and that is pretty much new as well. The video card is a Radeon 9250 PCI 256MB. The problem is that when I have the video card installed the system wont post. I put in an even older video card (Vodoo 3dfx) and the system booted up with no problem. I installed the Radeon video card on a separate system and it worked fine. Any ideas? I am completely stumped.
