Stuck in penumbra demo

[Linux.Blue]

I have windows also, but I am not liking it very much at all. My graphic card fried, so I replaced it. Both linux and windows detected it right away without any sort of problem. With linux I had to reconfigure in XFdrake, but still, it worked.
I reinstalled windows, because that's just what you do with windows, and it won't detect.
I tried the installation disc, get an error; I tried "add new hardware', nothing. I see in display, (in device manager or whatever), 'standard VGA card'
tried to uninstall it, and use the disc, but it just doesn't work.
If I can get this to work under linux, I'd be happy. I don't need windows for anything anymore; except maybe this demo, if linux fails to load it.
