I installed my voodoo in a motherboard (m810 pcchips) with a AMD Duron 800 Mhz, it worked fine in Windows but when i run any game ( 3d ) it hangs.... ???
The Voodoo3's tend to run very hot and my hand if there is insufficient case cooling.
Install the 1.05.00 drivers (IMO the best ones) and put a fan on the video card or improve your case cooling. Maybe that will solve your problem
