  1. I would appreciate it if someone 'in the know' could take a looka t the minidump files and give me some ideas about what I can look at next. I have followed the instructions about RAM cleaning, swapping slots etc. and could do with some more pointers. Appreciated..

    Hello and welcome to Techspot.

    3 minidumps crash at ntoskrnl.exe. This is Windows bootup kernel. They have a bugcheck of 9C.

    1 minidump crashes at sysaudio.sys. This is Windows System Audio WDM Filter driver. It has a bugcheck of 9C.


    This is a hardware issue: an unrecoverable hardware error has occurred. The parameters have different meanings depending on what type of CPU you have but, while diagnostic, rarely lead to a clear solution. Most commonly it results from overheating, from failed hardware (RAM, CPU, hardware bus, power supply, etc.), or from pushing hardware beyond its capabilities (e.g., overclocking a CPU).

    Regards Howard :wave: :wave:

    Sorry Pentium IV.

    Does that mean there is nothing I can do but buy new hardware? What part of my set up has failed? Do I replace the processor or the motherboard or the RAM?? Thanks for your help..

    Unfortunately I have no way of telling which hardware is faulty.

    It really is a case of diagnosing this yourself.

    Make sure nothing is overclocked.

    Start by checking your system temps.

    Then check your mobo for bulging, or leaking capacitors. See HERE for firther info.

    Check that your ram is comaptible with your mobo. Try running with just one stick of ram.

    Check that your psu is powerful enough for your system.

    Disconnect anything not required to run your system.

    Go HERE and follow the instructions for testing your ram/hard drive/page file.

    Regards Howard :)

    According to the debug report, it is L1 cache memory of the CPU. RMA the CPU.

    BugCheck 9C, {0, 8054da70, cc0000ff, 20040189}

    NOTE: This is a hardware error. This error was reported by the CPU
    via Interrupt 18. This analysis will provide more information about
    the specific error. Please contact the manufacturer for additional
    information about this error and troubleshooting assistance.

    This error is documented in the following publication:

    VAL - MCi_STATUS register is valid
    Indicates that the information contained within the IA32_MCi_STATUS
    register is valid. When this flag is set, the processor follows the
    rules given for the OVER flag in the IA32_MCi_STATUS register when
    overwriting previously valid entries. The processor sets the VAL
    flag and software is responsible for clearing it.

    OVER - Error Overflow
    Indicates that a machine check error occurred while the results of a
    previous error were still in the error-reporting register bank (that
    is, the VAL bit was already set in the IA32_MCi_STATUS register).
    the processor sets the OVER flag and software is responsible for
    clearing it. Enabled errors are written over disabled errors, and
    uncorrected errors are written over corrected errors. Uncorrected
    errors are not written over previous valid uncorrected errors.

    MISCV - IA32_MCi_MISC Register Valid
    Indicates that the IA32_MCi_MISC register contains additional
    information regarding the error. When clear, this flag indicates
    that the IA32_MCi_MISC register is either not implemented or does
    not contain additional information regarding the error.

    ADDRV - IA32_MCi_ADDR register valid
    Indicates that the IA32_MCi_ADDR register contains the address where
    the error occurred.

    How in the hell did you decode that info? :)
    Could you help me decode machine checks I got recently?
    Problem is I don't have dump since the machine only does cold boot, I am not sure if turning dump on would help. I can however post info from system event log although I am not sure how to interpret it correctly.
    Would you be so kind to look at it?
