CD drives missing under Windows XP SP3. UpperFilter/LowerFilter registry fix no good
I'm working on a friend's computer trying to restore it after a massive spyware infection. I have just restored the operating system, patched it, and installed all hardware drivers. No CD burning software of any kind has been installed yet, nor was a specific CD-ROM driver installed. Following a reboot from Windows Update, my CD drives (both of them) have vanished from My Computer. They show in Device Manager with Error 39 complaining that it can't load the driver for the device.
I've tried deleting them and rebooting to cause redetection, but that didn't work. I also tried the popular UpperFilter and LowerFilter registry fix that seems to solve this problem for many others. However, when I navigate to HKEY_LOCAL_MACHINE\SYSTEM\ CurrentCon trolSet\Co ntro l\Class\{4D36E965-E325-11C E-BFC1-080 02BE10318} I see no UpperFilter or LowerFilter entry at all.
I'd appreciate any further thoughts. Thanks!

find newer drivers...first uninstall drivers and then reinstall drivers...from Dell
oops...if it's a dell that is...for some reason i thought it was a dell..

It's not a Dell unfortunately. It's sort of a Franken-computer, cobbled together from various manufacturers. The key point is that it definitely was working when I initially started the rebuild. Unfortunately I'm not sure at what point it lost the drives. I noticed it after the Windows Update reboot, but it could've happened sooner after installing the drivers for some other device.

Possibly a chipset issue. Who manufactured the motherboard? Go to their support site and download the chipset drivers for your motherboard.

This is a K7 AMD processor with a SiS741 chipset. I just tried redownloading the IDE drivers for this chipset and reinstalled, but the drives are still vacant. I'll try doing the repair/reinstall of the OS tonight to see if that brings them back. In the meantime, if anyone else has any other ideas, they would be appreciated.
Thanks again!
Thanks again!

Thanks for comment anctech, at least I know I'm not insane. It sounds like this is a known issue, but one for which Microsoft doesn't have a solution at this time. The restore of the operating system mentioned above solved the problem, but now I also know not to install SP3 at this time. Thanks to you both.

Wish there was a less drastic solution to this problem, but that's not either of your faults. Thanks for the suggestions, which appear to be all Microsoft has to offer right now. :-)
