Since you have not received any responses so far, I'll try to give some 
suggestions. If you use headphones directly plugged into your CD and DVD 
drives while playing music and the music play back is good, the issue is 
apparently not hardware related. I would look for a program that is 
using a high amount of resources and, thereby slowing down the 
processing of the input from the CD and DVD players. You can find that 
by using the Windows Task Manager (control-alternate-delete) and looking 
at the Processes tab. By clicking on CPU you can list the processes by 
the amount of CPU usage and see if anything does not seem appropriate. 
If anything does show up, you can then decide how you might want to 
control it.

I hope this helps. If not, hopefully others can further assist you.

Played music discs in both drives and both played at very slow speed.  Replaced both drives, but result the same, and also replaced the Power Supply.  Would appreciate any advice to cure this problem.  Colin Joyce.
