UNABLE TO DETECT CD/DVD ROM

HL-DT-ST DVDRAM GSA-T20L ATA Device for HP PavilioN, Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) I just got a COMPAQ laptop for about 3 month now and it just developed a problem. I could not detect CD/DVD. It diplayed the following message:

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"

Hi, the error code that you have is a known issue from Microsoft that needs a registry tweaks. Error code means "Your registry might be corrupted (code 19)."
You can click on this link for your reference http://support.microsoft.com/kb/929461/en-us

To resolve this problem, remove the affected filter drivers. To do this, follow these steps:1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or confirmation, type your password, or click Continue.
2. Locate, and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters, and then click Delete.
4. Click Yes to confirm the removal of the UpperFilters registry entry.
5. In the right pane, right-click LowerFilters, and then click Delete.
6. Click Yes to confirm the removal of the LowerFilters registry entry.
7. Exit Registry Editor, and then restart the computer.

This will surely help you resolve your issue. Good Luck!!!

Thanks
