    Hi all,

    I have Aspire 7720 with Windows 7 (Upgraded from Vista). The computer is not recognizing my DVD/CD Drive while in windows (DVD/CD drive doesn't show in Device Manager but it blinks and works for a couple of seconds during bootup but doesn't boot from CD).

    What I already tried:
    - Registry fix (remove Upperfilter and Lowerfilter)
    - Ran registry scan/fix program
    - Ran Microsoft Fixit
    - Opened laptop and removed and then reattached DVD/CD drive

    What I found out:
    - Computer boots faster and doesn't heat that much if DVD/CD drive is not connected

    PS: This is the original CD/DVD drive that came with the laptop. I don't know the brand or model number of my DVD/CD drive since it doesn't show up in device manager. Also there are no DVD/CD drivers on Aspire website.

    Any suggestion is appreciated.
    Thanks

    Start Registry Editor (Regedt32.exe).
    Locate the UpperFilters value under the following key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

    On the Edit menu, click Delete, and then click OK.
    Locate the LowerFilters value under the same key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

    On the Edit menu, click Delete, and then click OK.
    Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value,
    if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software.
    If the problem recurs, consult with the software vendor for assistance.

    Restart pc,en
