Windows 7 Computer not recognizing CR-Rom drive

May 16, 2012 at 08:33:01
Specs: Windows 7
This morning I put a CD in the CD-Rom drive, nothing happened. The computer is not recognizing the drive. I looked in Device Manager, and there is a exclamation in yellow triangle by the drive. Under Proprieties for the drive there is this ,"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)". The drive was working fine last night. I tried to update the drivers but was advised they were current. Not sure what to do now, thanks for any advice on this matter.

Sounds like a filter driver problem. Microsoft recommends running the hardware and devices troubleshooter.

If that dosen't work you may want to do it manually.

Click Start
Start button
, and then click All Programs.
Click Accessories, and then click Run.
Type regedit, and then click OK.
User Access Control permission
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
In the navigation pane, locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
In the right pane, click UpperFilters.

Note You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 8.
On the Edit menu, click Delete.
When you are prompted to confirm the deletion, click Yes.
In the right pane, click LowerFilters.

Note If you do not see the LowerFilters registry entry, unfortunately this content cannot help you any further. Go to the "Next Steps" section for information about how you can find more solutions or more help on the Microsoft Web site.
On the Edit menu, click Delete.
When you are prompted to confirm the deletion, click Yes.
Exit Registry Editor.
Restart the computer.
