My guess is that the PCI card itself, or the device driver for it, don't properly support 64-bit hardware addresses. With more than 4 GiB of RAM (actually, even with just 4 GiB, but more RAM means it's much more likely), peripheral cards (like your video card) may appear at a hardware address above 4 GiB. That means the high half of the 64-bit hardware address word will start being used. If the card or the driver is improperly handling the high half (ignoring it, zeroing it, etc), then weird things like that could easily happen. When the card appears below 4 GiB (say, because you have less RAM), then mishandling the high half of the 64-bit word that way won't matter. Check for a BIOS update for your main board. Check for a BIOS update for the video card. Check for a driver update for the video card. Try moving the card to a different slot. It might also be bad memory module or a bad memory slot. Try moving modules/sizes around into different slots to see if the problem moves with it. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
