Open GL conflict with Myth III

When playing Myth 3, the game loads, then goes very, very slow. After this, the game stops, and we get the following error:

MYTH3 caused an invalid page fault in
module <unknown> at 0000:00000001.

After this, the computer reverts to windows 98, but in a reduced pixel format (640 x 800), and the colour of the screen reverts to a very pale colour. Also., the taskbar disappears.

This is only happening after loading openGL to the system, and additionally, open gl seems to be causing conflict with other parts of the system. I have reloaded drivers for the nvidia TNT card, but to no avail.


any assistance would be very much appreciated, im a bit of a novice to this thing!
