NO audio, no dvd rw, no webcam, etc,

[Guest]

The next day after I defragmented for the first time ever, the computer did
not have any sound or audio, is like it doesn't have dvd rw, or speakers or
webcam and of course can't use any music programs or anything that has to do
with audio.

PLEASE HELP!!!!!!!!!!!!!!

Go to Start/Run, and type DEVMGMT.MSC , highlight all the sound devices,
Action menu, "Uninstall", then restart Windows, to find the device drivers
again automatically.
