Media audio controller problems

Hi, I just formated my computer and I cant update my sound card, I have a soundmax 3d soundcard integrated in the motherboard, which is an Intel 865 PERL 800HMZ. My processor is a pentium 4 and I am using windows XP home edition. Every time I go to device manager and try to update the driver manually (there is a yellow ? next to the media audio controller)an error window pops saying: No driver found, please reboot your system and try again. I have been trying to fix this probloem for hours, any help would eb greatly appreciatd =)
