Cd-rom And Cd-r Drives Bizarre Behavior

All of a sudden both my CD-ROM and CD-RW drives are acting strangely. They are both acting the same, so it seems a Windows problem (XP Home). When i put in a CD of any type after a restart, it works fine. The next CD I put in shows up in Explorer labelled exactly like the first one, and if it has an autoplay function, it calls up the same menu as the first one. I've tried numerous CDs of several types and the same thing appens.
Example, a game CD starts the game like always. Eject the CD, put in a program install CD and the game menu comes up. Of course, if I try to play the game with the wrong CD, it says my files are corrupt or missing. Another example, one game will autoplay its start menu (if it's the first one after restart), but when I go through the game setup menu, it tells me to put the correct CD in the drive (and it is in there already).
I've tried several solutions to no avail including uninstall and reinstall the drives--System Restore won't let me restore because the last point was on a Windows Update
