I'm not sure what video driver I had, but I had just updated it today from the most recent from ATI's site.

As for exchanging parts, the Duron isn't mine, it's a friends I tested it on, and the Dual MP is my schools that I've got for the summer.  I do, however, have a duron 850 with a GF2 GTS and a Voodoo3 3000 in it, but I still don't think it's the video card...

Any way, I installed 2000 on my computer, and it works...sort of...  It will get to the loading screen, then just before the bar hits the end, it locks up.  However, I can get out of it by CTRL, ALT, DEL, so atleast I've gotten somwhere...
