Hmmmm............
Are you using the drivers that came on CD ROM with the card or the latest drivers from the Creative website? Does it flash a blue screen on the reboot? Just to make sure, did you turn off the onboard soundcard?
When I installed my Audigy with a XP operating system I disabled the onboard sound in the BIOS, turned the computer on with the card installed, and then once in Windows it found the new hardware and started the hardware wizard. At this point I installed the drivers CD ROM and Windows automatically pulled the correct drivers. All the drivers and patches off the Creative site did not work for me and I got botched sound. Only the ones on the CD ROM disk worked properly. I do get a blue screen on bootup sometimes and just hit the reset button and it boots up normally like it never happened. Hope this helps and gives you some ideas.
