My daughter has a Dell Inspiron 530. She was in the process of removing programs she no longer needed/wanted and somehow managed to delete the or at least disable her Audio sound driver. I am far from being computer competent enough to see if it is still there but not able to locate. The driver disks are missing in action as well. This is a Windows XP system. Is there somewhere online I can go to download this missing driver or maybe restore the one that the computer shows no sign of?
