Any ideas how to troubleshoot STOP 0x1000007e ?

  1. I am getting daily (sometimes 2 or 3 times daily) random reboots on my
    system and it is getting really frustrating.

    The DumpSave report each time says something like:

    I used DUMPCHK.EXE to expand the minidump file produced but can't work out
    how to stop the problem. I have reproduced the output below.

    The things I have tried so far are:

    * Looked up the STOP code on MSKB and there are two entries both related to
    resuming from hibernation. I do not use hibernation so that can't be the

    * The output below suggests that the sound system may be involved in the
    problem as KMIXER, DRMKAUD, SPLITTER and DMUSIC are all part of the MS
    Kernel for the audio system. I have uninstalled all my audio drivers and
    reinstalled from scratch - they are Audigy ZS2 Platinum Pro drivers. I also
    have a Hauppauge TV tuner installed which has audio drivers. Finally I have
    SoundTaxi which converts ausdio files (but uses some driver technology to do
    its job).

    * Unlocker is part of a utility that allows files in use to be unlocked when
    required (it is a user action so no automated unlocking of files). I have
    uninstalled this and left it off my system for a while but it didn't make
    any difference so I have now reinstalled it as i find it very useful.

    * I have uninstalled and reinstalled all my motherboard and graphics card

    * I have removed a second USB disc drive (mentioned in another thread) and
    that has removed the probelms with drive page errors appearing in my system

    * I have run stress tests on my system which worked flawlessly for hours at
    a time (I used nVidia's system stability test and while it was running I
    used 4 different AV packages to play DVDs, Video and multiple audio files,
    surfed the internet, scanned, printed images etc)

    * I have run DOS based utilites to test memory and other onboard hardwear -
    no problems were shown up.

    Note apart from the SaveDump entry and other entires during recovery from
    the STOP condition there are no other errors appearing my system logs. All
    my hardware/software seems to work normally and 95% of the time I can do
    anything I want with the system without problems.

    Any help would be really appreciated

    Your mini dump analysis shows you have a bad component... but sometimes this is caused by an infestation. Just about any component can be the cause.
    We usually check memory first, then replace all drivers. Since this is difficult and time consuming, keep a running list of everything you try and every component you test.
    Where are you getting your drivers? Try another source... such as the manufacturer of the component.
    Sometimes it is helpful to go back to an earlier driver from the same source, or try a different source. Some driver sources can be found with a Google search.
    Sometimes it is necessary to download the drivers to a site where you can find them, then remove or disable the existing driver.
    Install the new drives in SAFE MODE if it will do that.
    Usually this is a driver problem or a defective video graphics, sound, or modem card, or a memory failure. But can sometimes be the electrical interference of a bad cpu fan or power supply. It can also be a defective hard drive at times. Thus, you can have a long period of detection... as you obviously already know.
    The first thing I would do, if it will stay on, is run MemTest86 for four hours or 7 passes... on each module, one at a time.
    Then change out the video graphic card, then the sound card, one at a time...

    Do you get the problem when you remove the sound card altogether?
    I am sure other people on this forum will have good suggestions.

    Thanks - I ran memtest+ from a floppy (latest version) overnight and it didn't generate any errors at all. I know Memtest isn't perfect so I also tried MS's own memory tester.

    All the drivers on the system come from the manufacturer's web sites for those components except for the mobo and graphics. For those I downloaded directly from Nvidia's website (since they are where the graphics drivers come from anyway).

    It seems purley random when the errors are generated - they can be everything from 1 to 2 hours after the last one to a day or two, they can be when the system has been left alone doing nothing or when it is doing a lot of work.

    There just isn't any pattern. It really doesn't help that Microsoft are absolutely terrible at documenting errors.

    I have just uninstalled SoundTaxi and Unlocker from my system and the drivers are no longer present in Device Manager and yet I have also got another restart with the following dump:

    I'll try ripping out the sound card and using onboard sound instead, and also rip out the TV card.

    Attach the most recent minidump. Both those crashes look to be the same.

    I suspect you will eventually find it, and it will be a hardware problem...
    The next time it occurs, pull the case cover to see if you detect the odor of hot metal or feel any board that has a temperature.
