I just got a voodoo 3 3000 off the f/s f/t board, and i put it in today. My computer was booting fine wuntil it got to the scrren with the windows 2000 logo and the computer locked up. The heatsink on the card is really hot, and I added another small heatsink and fan on top of that to try to cool it more, but it still gets so hot. When I put my old video card back in, the system booted up fine. Why is it locking up?
