Watch the POST screens at start up to verify the BIOS is actually configuring your CD drive. Should be identified by model in those screens.

Thanks, but when I go into the Bios to configure it, the CDROM shows up by name.
What I plan to do is to completely reload th Windows 7 OS to see if that fixes it. It found the CDROM when I initially loaded the OS. Any other Ideas?

You are NOT understanding what I am saying. The BIOS screens and the POST screens are not the same thing. When you first start up your computer, long before Windows starts you should see some text on the screen. That is the POST screens. If the drives are not shown in the POST screens properly then they are not going to be seen in Windows.

While the fact a drive is listed in the BIOS drive configuration area is usually an indicator it will be configured at boot time but not always the case.

If the drive in question is the same drive you use to install Window 7 then two things are apparent. First, the drive is being configured properly by the BIOS, second, that it is not only a CD rom but actually at the very least also a DVD rom. More likely a CD/DVD combination burner drive. It is a matter of terminology. CDrom indicates the drive is ONLY capable of READING CDs.

Now, is the optical (CD) drive an IDE/ATA or a SATA type?

Did the drive in question previously work OK in Windows 7?

Do you have more than ONE optical drive installed?
