Hi Rob,

I would suggest you to try performing an operating system reinstall and take the computer to factory state by using the below link:

http://dell.to/1iaXWvk for windows 7 operating system only

http://dell.to/1a3ZA0P for Windows 8 operating system only using Dell Backup and recovery.

If still the issue persists then you may use the below link and check warranty status:

If the computer is in warranty do send me the system service tag via private message. I will check and see what can be done.

If the computer is out of warranty you may contact the out of warranty repairs team on 18002884410 (U.S only). They can help you further.

I had this no sound problem constantly previously

What I did to fix the problem is:

Complete shut down your computer for 5 to 15 mins

Hope this help.

If you've rescued back your sound problem, I suggest you to shut down Windows update auto check becoz this is the program that I found that is not always shut down properly
