NEED DRIVER: The Device Manager is telling me that the driver for the Compaq SC-140S CD is missing or corrupted, and I can't find one anywhere. As a result, I can't use any CDs. This problem arose when I installed Windows XP. I don't really know what the Interface type is - - the CD ROM is built into the Compaq Presario 7360. Please help. Thank you.

It'is a Windows XP thing, losing drives when installing/un-installing burning software… or just a Windows XP thing where you get error messages.

If the drive(s) are still listed in the Device Manager, delete all listed, then carefully follow this fix:

"Upper/Lower Filters:

a. Click on Start --> Run --> and type in 'regedt32' followed by the enter key
b. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or clicking the "+" next to it.)
c. Expand the "SYSTEM" Key
d. Expand the "CurrentControlSet" Key
e. Expand the "Control" Key
f. Expand the "Class" Key
g. Look for a key containing the following string of letter and numbers:
{4D36E965-E325-11CE-BFC1-08002BE10318}
h. Highlight this key by left clicking once on it
i. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these delete them by right clicking on them and choosing "delete"
j. Exit the registry by clicking on the "X" in the top right hand corner of the screen.

reboot and now your drive(s) should work fine.
