So a friend of mine is trying to install an Audigy soundcard in his pc, but everytime he installs it the display won't come up. It won't even post. Now I'm working on it, having the same problem, and am at a loss for what to do next. I don't know a lot about the pc, I think it's got a an Asus mobo, probably about 2 years old, a duron 800, and he's got a pci ati 128 video card (which i think is part of the problem). But the board has an older agp slot so none of my spare cards will fit. Any suggestions?
