i suddenly have no sound! help!

[c wood]

I have always had sound on my Dell Dimension XPS running Windows XP Pro,
SP2.
A couple of days ago, all sound ceased!
I can't hear sound in browser videos ... not in CDs played on the CD drive
.... not the Windows sounds. I've tried several repairs and a system restore
to last week, but no change. I am also getting an error when I try to
synchronize my clock. Are the problems related?
HELP!!
Has the sound card died? Has something been switched off or de-selected???
HELP!

In addition ...
I have tried a driver update and gotten the dreaded BSOD!! - three times.

Open the control panel to System, hardware, device manager and delete the
sound card entries. Assuming you have the Dell resource CD, reinstall the
audio driver following the instructions on the resource CD.

I doubt that the clock problem is related to the sound problem. Please post
the exact error message you get.

Check to see if by chance you hit the mute button - you may have one at the
top of the keyboard - or click on the volume icon and see if you've clicked
on the mute function.

Also, check that you do not have a head set or microphone jack plugged in
thus causing mute.

Finally, have you checked the volume control and if you have external
speakers that they are not unplugged from each other or the power supply.

Good luck.
