I have a crashed Dell 8400 computer that had windoze XP and I changed the operating system to Windoze 2000 Pro. Dell doesn't provide windoze 2000 Pro drivers for that video card. I went to ATI's website and found the catalyst 6.2 drivers for the x800 card and downloaded them and installed them. The video worked but I got an .netframework error and downloaded that fix. Once all of that was done now the ATI card works. It only took a day of downloading all the video files and seeing they didnt work before going to the ATI website. Next time I will not rely on Dell.
