Thanks for your replies guys. The problem is it won't even register, I plug the monitor into the card and there's nothing, the motherboard lets out a series of panicked beeps and I just get a blank screen.
It sounds like it could be the jumper settings allright, I'll give it a go!
As I said, the card slots in perfectly and Voodoo's are renowned for their ease of installation.
Flying in a glass flightdeck is a lot easier then his!!
