  • I have an Acer Extensa 5420 and after installing updates my cd/dvd rom is not working.  In the device manager it says code 39 and that drivers are missing or corrupted.  Can anyone help please.

  • Hi,

     

    Please take the following steps to troubleshoot the problem.

     

    Step 1: If you have installed any CD/DVD-burning software, please temporarily remove them from "Control Panel"-> "Programs and Features".

     

    Step 2: Modify the Registry

    ====================

    1. Click the Start Button, type regedit in the "Start Search" text box and then press ENTER.

     

    2. Navigate to the following key:

     

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

     

    3. Right click the {4D36E965-E325-11CE-BFC1-08002BE10318} entry, choose "Export", select Desktop in the Save in box and type backup in File Name. Click Save.

     

    Please Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.

     

    4. Highlight this key ({4D36E965-E325-11CE-BFC1-08002BE10318}), on the right pane, and then check if Upperfilters and Lowerfilters value are present. If so, please right click on the values and select "Delete" to remove them.

     

    5. Restart the computer

     

    Step 3: Remove the DVD-ROM drive

    ===========================

    1. Click the Start Button, type devmgmt.msc in the “Start Search” box and press Enter.

    2. Expand "DVD/CD-ROM drives".

    3. Right click the DVD-ROM drive, and click "Uninstall".

     

    Then, please restart the computer. Does the DVD-ROM work properly now?

     

    Hope it helps.

  • I have similar problem. My Dell Inspiron 1525 laptop o/s vista home does not recognise my DVD-ROM drive. This has happened three times. The first two times modifying the registry as per step 2 above solved the problem (i.e deleting upper and lower filters).

    However this time that action failed to solve the problem. There were no filters to delete!

     

    I have tried option 3 above (removing the DVD-ROM drive) but the problem persists. What else to do???
