Original Title: I am having problems with my dvd/cd-rom drive.
It says windows cannot start this hardware device because its configurations information (in the registry) is incomplete or damaged (code 19). Does anyone know how I can fix this? I have a Dell XPS running Windows7 with the standard CD-ROM drive with Blu-ray.

Code 19 means there is a driver conflict such as two devices trying to use the same resources.
Having too many CD/DVD programs can cause strange issues, especially if they load parts of them-
selves at StartUp as they will compete for resources. This does not mean this issue was caused by
those however it is a possibility depending on which and how many you have installed.
Stage 1 : Please do all the below even if you have done some before as it is often the total
process which solves the issue.
Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab -
click Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL -
REBOOT this will refresh the default driver stack. Even if drive is not shown continue
Then work your way through these - remember the drive could be bad, could have a loose
cable or slight corrosion on the contacts (usually for a laptop) and other issues.
Another possibility is that the cables are loose. Remove ALL power, then check cables in both
ends. Remove and replace, do not just snug. For laptops you can often clean the power and
data contacts with a pencil eraser.
Some DVD drives do not use the Windows default drivers so check with the System maker and
device maker to see if there is firmware or drivers for you drive if needed.
Stage 2 : You could have drive issues as the CD/DVD is actually 4 drives in 1 case ( CD & DVD
burn and CD and DVD read). So it is not unusual for 1 or 2 parts to not function while the others
do so properly.
Did you complete the troubleshooter for the drive that still does not work? There are some
registry entries that the troubleshooter does not fix and those "might" be the cause.
Check with your System Maker and Device maker for both possible firmware updates and the
correct Registry entries for your drive.
These are the keys I think are the ones in question - for the CD/DVD drive sub-keys of course
as there will other sub-keys in these keys. Be sure to ask for specific keys involved as well as
