Can't uninstall or reinstall...

I just got my "Dream Machine" up and running with the
best I couldn't afford but did any way. I used XP Pro for
an OS and wanted to finally update my sound and video
drivers after setting up all my preferences, e-mail and
users. Video drivers went good but I get an "error number
0x80040201 An event was unable to invoke any of the
subscribers" when I try to unistall my Audigy 2 drivers
and software with ADD/REMOVE Programs. Even if I autoplay
the installation disk I can't reinstall the software or
remove it. And my eax control panel won't come up,
instead it says no sound blaster detected. Yet the sound
card is working and showing up in Device Manager with the
proper drivers. I'm stumped. Is this what XP Pro is all
about?? Headaches? I know ... I'm the headache... another
backyard computer mechanic... Help if you can... Thanks
for your time
