What_does_this_button_do is right in that it could be config on your OS.
It could also be as simple as dust in your drive. You can get CD-ROM cleaners in computer shops. They remove dust and particle build up on the laser lens.
Or you could try what I did once, open the CD tray, and blow ( with a dry mouth ! ) into the drive area a couple of times. Worked for me once
It could easily be a drive conflict on your OS though, Can you still see the D drive ( if thats your cd-rom mapping ) in Windows Explorer ?
Good luck
