A while back I purchased a 3d prophet II titanium card and installed it. Well, it seems to work fine except that when I go to device manager and look at display adapters, NVIDIA GEFORCE2 DDR has the yellow circle with the ! in it, and if I click properties it says, "This Device Cannot Start (Code 10)". I have updated the drivers, reinstalled the software, and nothing fixes it. I also could not install the 3d tweak software because it said something about it not being compatible with something. Does this sound like a Windows XP compatibility problem or motherboard problem? Thanks for the help.
