I've recently been building an new computer. Everything worked fine until I put in my graphics card(GeForce 8800 GTS). Then no display appeared. When I took it out everything was fine. Somebody told me it's because my intergrated chipset is still functioning. Is this it? If so, how do I disable it. I looked around in the BIOS and it gives me an option to select the PCI-E card but no option to disable the onboard one. My motherboard is a DG965WH, by the way.
