No Sound

Hello,


I have a Dell Dimension 1100 Desk Top. I can not get any sound from my computer. I checked all volume and sound settings and all are enabled, speakers connected properly and turned on, valume is at max. It appears somehow, the sound drivers have been removed from my computer (if that makes any sense). When i bought the computer it did not come with operating system CD or drivers CD. I have already tried retoring the system to an earlier state when the sound was working but that doesn't work either. Any help or advice would be greatly appreciated.

Thank you
