computer will not recognize CD Rom

[alkscd]

My Gateway laptop model ML3109 computer will not recognize CD Rom. Operating system Vista home basic. The machine is fairly new 6 months old, used very little by my wife. The drivers are all up dated. In the device manger the CD has a yellow marking. I uninstalled. restarted the mechine still no good. Please Help!

Had the CD-ROM worked prior to this, or is this a new one you've installed?

Yes it's alway been working. I don't use it much. But I always see it.

Please look at the details in device manager and post exactly what it says as to why it's not working.

It says,

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available.

Thank you,
I fixed the problem. I used the following procedures.
RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

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.

I wasn't sure if that procedure would work with Vista - looks like it does. Thanks for posting the resolution.
