Dell Studio 1737 Audio Doesn't Work

     Forum,
  Okay, so I cannot get any form of sound to come from my laptop what so ever. I have updated all drivers, all drivers are "working properly" and there is no sound from speakers nor my 3.5mm jacks. I've disabled and enabled my audio devices MULTIPLE times, and uninstalled them and reinstalled them MULTIPLE times. I'm very VERY frustrated at this point. Could it possibly be that the speakers themselves can be shot, or a simple re inst. of OS?

I am running win 7 Ultimate x64.                PLEASE gimme the answer. I'm dying to know it.

Thanks, Carey.
