I have the same mobo in my other computer, but not the same video card in it.
It might by the chipset of the board that is causing problems. The Via MVP3 did not have the best AGP support, so that could be the problem. Where there any drivers for any other video card installed on the computer before the Radeon, because than it might be a driver problem. Win2k, like was said before, does not really work with the Radeon at all.
I think it is the motherboard and Win2k/drivers. You said you are running the latest BIOS version, right? Install the latest Via 4in1 drivers as well, they helped in my other computer.
