I'm having a problem. I can't figure out how to disable my on-board video adapter. so when I place my video card into the pci slot, i can see bios and the windows xp professional logo, but when it starts to load the desktop, the screen is black. also, the only way i'm able to use my on-board video adapter is to remove the new video card from the pci slot. it wasn't so much of a problem, because i've been able to use the newer video card before. but that was before I had to reformat. But now I really need to be able to use it because recently my screen has started to compress itself to half the monitor's size. does anyone have any suggestions?
