    Unexpected Kernel Mode trap


    Just recently I've been getting blue screen crashes at apparently random intervals, all due to the same cause, according to NirSoft's BlueScreenView, which reports Unexpected_Kernel_Mode_Trap caused by address ntoskrnl.exe+70740. How do I troubleshoot this, because I have absolutely no idea. I tried to upload the minidump but apparently dmp files are not allowed?

    Sorry - I realise I should have enclosed a zipped minidump, which I now do.

    The dmp(s) point to ntkrnlmp.exe or ntoskrnl.exe as the probable cause. We know this is not the case, as these are core OS files, and will definitely not cause a BSOD. They are just the default files the debuggers blame when they can't see a better cause. We need to enable driver verifier to help pinpoint the faulting driver..

    - Go to Start and type in "verifier" (without the quotes) and press Enter
    - Select "Create custom settings (for code developers)" and click "Next"
    - Select "Select individual settings from a full list" and click "Next"
    - Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
    - Select "Select driver names from a list" and click "Next"
    Then select all drivers NOT provided by Microsoft and click "Next"
    - Select "Finish" on the next page.

    Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

    Code:

    These drivers are out of date and need to be updated, or uninstall the associated program.

    Thanks for the reply, but just a question: I've read elsewhere on the forum that people have got into trouble using driver verifier. Is this safe to do?

    Just another quick question with regard to the out of date drivers you referenced in your original reply. How do I update the nVidia ethernet driver? I can't find it anywhere on the nVidia site and my nVidia graphic card driver is up to date (I assume these two are connected?)

    Tews:

    I followed your instructions to enable the verifier and after that there has been a BSOD. But my Windows is 8 Developer and I do not know where and how to find the log with the results. Could you guide me? tks
