No sound after XP reinstall, tried everything, please help

Thanks in advance for reading my post!

I had to reinstall Windows XP Professional on my Dell Precision Workstation 370. Everything is fine expect I have no sound. I have uninstalled and reinstalled the SoundMax Intergrated Audio updated drivers many times. I have check to make sure intergrated sound is enabled in bios. I have updated bios. I have scanned my computers for errors and they were fixed, I checked to make sure nothing was muted, and a few other things I can't remember. I do have an exclamation point next to Multimedia Audio Controller under Other Devices in Device Manager, btu I cant seem to get rid of it.

Any suggestions!
Thanks!

Did you also install your chipset drivers?

Be sure that the soundmax drivers you are installing are from this link below, and not directly from soundmax.

Yes, I installed the chipset drivers. I have also tried installing the sound rivers 1) off the dell resource CD 2) from the dell website and 3) directly from Sound MAX, none of the above work.
