How do you disable Intel(R) G33/G31 Express Chipset Family video card?
There is no need to disable the on board video card. Simply shutdown your PC, unplug it from the wall, open the case, and install the video card as the manual instructs. You will need to close your case, plug your computer in and start it up. Once your windows has loaded, insert the disk that came with the video card, at about halfway during the installation the screen may loose its signal, simply unplug the monitor cable from the motherboard and plug it into the newly installed video card.
