Dell Dimension 3100 Audio Driver Problem

earlier midnight, my pc "died" and i was forced to reinstall a clean version of windows xp. unfortunatley i misplaced by windows xp sp2 disc and the only option i was left with was a sp1 disk from years back. i reinstalled windows installed video card/chipset/video files/network, and everything was going fine until i restarted my pc to finish installing the sigmatek files for my pc. Thats when i got an error message stating "your version does not support this audio file" (something along those lines). I tried restarting, reinstalling the file, but no dice. Does anyone have any suggestions?
The only thing i could think of was maybe the sp1 os isnt compatible with the audio file (http://support.dell.com/support/downloads/download.aspx?c=us&cs=19&l=en&s=dhs&releaseid=R114282&SystemID=DIM_PNT_P4_3100&servicetag=&os=WW1&osl=en&deviceid=8907&devlib=0&typecnt=0&vercnt=2&catid=-1&impid=-1&formatcnt=1&libid=3&fileid=150155)
^that being the one i downloaded and tried installing. Any help/advice would be good.

some pc info: dell dimension 3100
os: microsoft xp professional version 2002 (sp1)

thanks in advance for any advice or tips that can help me solve my problem. the beeping noise i get instead does get annoying after the 50th beep..
