My Computer Not Recognizing CD-Drives

[havax]

Just recently I haven't gotten my computer to recognize any of the CD's I am putting into either drive (a DVD R/RW drive or my CD-RW drive). Not only does nothing happen when I put in any CD (I have tried many), but also when I open up My Computer I don't see any drives listed under "Devices with Removable Storage" besides my 3 1/2 Floppy (A drive.

What can I do to make my drives work again? I did build my computer, but everything has been working smoothly until this.

Please help, thanks!

A few things you have to share with us.

What transpired "just recently" when your optical drives stopped being normal?

Are your CD drives recognized in the BIOS?

Are they recognized during the POST messages?

Are they showing up in Device Manager?

How are they physically hooked up?

When they were okay, what drive letters were they?
