I had just installed a game in winXP and after installation I noted I could not get the cd to eject when I pressed the button. When I looked at My Computer, the drive icons for the cd-rom drive and the dvd drive were missing. I used System Restore first and restored back from two days ago. It said the restore was successful. Yet my two drives are still missing. Doing some research at the MS Knowledge Base, I found two articles about missing drives that entailed some regedit to remove lower and upper filters in a certain key entry. I did that but it was of no help. When I look at device manager, there is no yellow exclamation point anywhere, and there is no text indicating CD-ROM or DVD. If I attempt to add a new device, I don't have any option to choose a cd-rom drive and it doesn't see it on its own during a scan. Greatly appreciate any help.
