Hi guys, i just bought a Retail 3D Prophet II MX (GMX), from Hercules/Guillemot, to replace my old but trusty Creative Labs TNT2 Ultra Card. Problem is that i can only use the GMX on the Standard VGA drivers. If i install the Guillemot Drivers, or the 6.18 Detonator drivers, windows hungs without even showing a pixel. I stripped all the components from my motherboard leaving it just with the GMX. Any idea please! Do i have to change motherboard???
