Sound card not working

I have jsut installed Win XP pro, and I cannot get the
sound card to work. When I remove the device form device
manager, and restart the computer, XP will detect new
hardware, but cannot identify it. I can install it
manually, but it doesn't produce any sound. My sound card
is a SB PCI 128 card, and the drivers sould be built into
windows. I have tried downloading the updated drivers
from the creative website, but when I try to execute the
file, all I get is a popup that says "information" with
an OK button -- no text. I have also tried following all
the directions in the troubleshooter utility, but it only
says that it cannot solve the problem! Hopefully someone
here can help.
