One of my PCs has an integrated Intel GMA3100 video card (G33 chipset). But I also have a dedicated PCI x16 card in there and am not using the GMA3100. I've read somewhere that the GMA3100 automatically disables itself when you install a PCI x16 card onto the motherboard. Windows (Vista) device manager does not display it under "Display Adapters" anymore. However, when I scan system specs using Lavalys Everest, it tells me that GMA3100 is enabled. Is this just an error by Everest, or is there a way to manually disable GMA3100?
