    Having followed the instructions in "DVD/CD suddenly stops working
    (GMA-4082N)" I can now see my DVD/CD as normal. Now when I insert any DVD or
    CD, blank or otherwise, my PC now blue screens with the message
    "APC_Index_Mismatch". Searching the web reveals its a kernel error, which is
    Any help appreciated.

    I did a google search on "troubleshooting apc_index_mismatch vista" (no
    quotes) and got a lot of hits. The following seems to me to be a good one
    (it applies to Win2K, but the condition is the same in Vista). I just copied

    Error Message:
    STOP: 0x00000001 (parameter, parameter, parameter, parameter)

    This is a Windows 2000 Executive character-mode STOP message. It indicates a
    mismatch of thread and asynchronous procedure call (APC) indexes. The most
    common reason to see this message is if a file system has a mismatched number
    of KeEnterCriticalRegion compared to KeLeaveCriticalRegion.

    User Action:
    If this is the first time you have booted after installing new hardware,
    remove the hardware and boot again. Check the Microsoft Hardware
    Compatibility List to verify that the hardware and its drivers are compatible
    with Windows 2000. For information about the hardware, contact the supplier.
    If you are installing Windows 2000 for the first time, check the Windows 2000
    system requirements, including the amount of RAM and disk space required to
    load the operating system. Also, check the Hardware Compatibility List to
    verify that the system can run Windows 2000. If Windows 2000 is loaded and no
    new hardware has been installed, reboot with recovery options set to create a
    dump file. If the message continues to appear, select the Last Known Good
    option when you reboot. If there is no Last Known Good configuration, try
    using the Emergency Repair Disk. If you do not have an Emergency Repair Disk,
    contact your technical support group.


    Another poster on a site explained that he solved this error by removing
    some RAM that tested bad using a memory tester (Vista has a built-in mem
    tester). Another site had a post by a person who solved this error condition
    by removing 2 GB of 4 GB of RAM he had installed. Apparently, his
    motherboard and BIOS didn't support 4 GB of RAM. Anyway, to get more
    information, if this isn't sufficient, try using google and search on the
    criteria as indicated above.

    Let us know how this turns out for you.

    Thank you for your reply. I read the same MSDN page on Win 2000 and tried
    the suggestions with the exception of the emergency repair disk. I also
    tested the RAM (no problems found) but I'm afraid the problem remains.
    Further suggestions most welcome.

    I can't provide more or better information than that which can be found on
    the Internet. Perhaps someone else?

    try a system restore first
    if the problem continues go to the drive manager and uninstall the DVD
    drive, then restart. try to find a driver or firmware update for your
    DVD drive.

    if the issue continues try running a chkdsk /r (it is better if you run
    it fron the recovery console (using you windows recovery CD))
    reinstall windows if the issue continues

    Thank you motarola2.

    I've found no Microsoft information enabling me to deal with this issue, so
    I've formatted the drive and re-installed. I haven't had to do that since
    Windows 98!
    It's all working normally now, for the moment.
    The most positive thing I can say on the subject is, "C'mon Vista SP1!!".
