Windows 10 Blue Screen "Unexpected Kernal Mode Trap" RRS feed

  • Question

  • I recently updated a Windows 7 PC to Windows 10; Dell Inspiron 5521. After the update I am experiencing a blue screen error each time I connect a USB device to one of the USB ports. This is occurring with multiple devices, e.g. thumb drive, e-reader, etc., but not with each and every such device. The same USB devices which are now causing the blue screen worked without error prior to the update and continue to work without issue on other Window 7 machines.

    To date, I have uninstalled and reinstalled each of the USB drivers. I also re-flashed the system BIOS with the most current version. All other system drivers are up-to-date. Unfortunately, there has been no change in the blue screen error. I continue to receive the following error: "Unexpected Kernal Mode Trap."

    Any suggestions as to what may be causing this?

  • Bugcheck 7F is UNEXPECTED_KERNEL_MODE_TRAP

    One of the things that this can be seen with is malfunctioning RAM, mismatched RAM or RAM not on the QVL.

    To evaluate the BSOD please post logs for troubleshooting.

    Using administrative command prompt copy and paste this whole command.

    Make sure the default language is English so that the logs can be scanned and read.

    Choose the applicable link for the operating system:
    https://www.tenforums.com/tutorials/3813-language-add-remove-change-windows-10-a.html
    https://www.eightforums.com/threads/language-add-or-remove-in-windows-8.5849/
    https://www.sevenforums.com/tutorials/87317-display-language-change.html

    The command will automatically collect the computer files and place them on the desktop.

    Then use 7zip to organize the files and one drive, drop box, or google drive to place share links into the thread for troubleshooting.

    https://support.office.com/en-us/article/Share-OneDrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07

    This command will automatically collect these files:  msinfo32, mini dumps, drivers, hosts, install, uninstall, services, startup, event viewer files, etc.

    Open administrative command prompt and copy and paste the whole command:

    copy %SystemRoot%\minidump\*.dmp "%USERPROFILE%\Desktop\"&dxdiag /t %Temp%\dxdiag.txt&copy %Temp%\dxdiag.txt "%USERPROFILE%\Desktop\SFdebugFiles\"&type %SystemRoot%\System32\drivers\etc\hosts >> "%USERPROFILE%\Desktop\hosts.txt"&systeminfo > "%USERPROFILE%\Desktop\systeminfo.txt"&driverquery /v > "%USERPROFILE%\Desktop\drivers.txt" &msinfo32 /nfo "%USERPROFILE%\Desktop\msinfo32.nfo"&wevtutil qe System /f:text > "%USERPROFILE%\Desktop\eventlog.txt"&reg export HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall "%USERPROFILE%\Desktop\uninstall.txt"&reg export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components" "%USERPROFILE%\Desktop\installed.txt"&net start > "%USERPROFILE%\Desktop\services.txt"&REM wmic startup list full /format:htable >"%USERPROFILE%\Desktop\startup.html"&wmic STARTUP GET Caption, Command, User >"%USERPROFILE%\Desktop\startup.txt"

    There are two files for you to find manually:

    a) C:\Windows\MEMORY.DMP

    Use file explorer > this PC > local C: drive > right upper corner search enter the above to find results.

    b) dxdiag:  

    In the left lower corner search type:  dxdiag > When the DirectX Diagnostic Tool opens click on the next page button so that each tab is opened > click on save all information > save to desktop > post one drive or drop box share link into the thread

  • If you have updated all divers especially USB drivers and chip drivers to the latest build from manufacturer website, you need to contact Dell after sale support for help.

    https://www.dell.com/support/home/sg/en/sgdhs1/product-support/product/inspiron-15r-5521/drivers

    Disable third-party security software, only use Windows Defender for test.

  • As requested, I have up-loaded the log files to a folder on OneDrive. The link is:

    https://1drv.ms/u/s!AtnXFDB3rc4qgg7bkqABLh1uvJtC?e=DAzJXR

    All of the log files are contained in a single 7zip file named "Troubleshooting Logs - Unexpected Kernel Mode Trap."

    Please let me know if you require any further information.

  • I ran the command line a second time as requested and uploaded a second zip file named

       02 - Troubleshooting Logs - Unexpected Kernel Mode Trap.

    The original zip file has been renamed to

       01 - Troubleshooting Logs - Unexpected Kernel Mode Trap.

    I included in the second zip file a text file named "Command Line" which contains a copy of the command line used along with the output generated by it so that you can verify that the correct command line was used.

    Note that the command line output states the following.

           16 file(s) copied.
       The system cannot find the path specified.
            0 file(s) copied.

    I believe this was the case in the initial run as well.

    Both zip files are in the same OneDrive folder as before, so simply use the link provided previously to access each.

  • The issue is now resolved.

    I removed each of the programs one at a time in the hopes of identifying if one or the other was causing the Blue Screen error. I decided to remove the Symantec program first. After removing the program and restarting the computer I connected one of the two USB devices that was causing Windows 10 to crash. No such error occurred and the device connected without issue. The same was true when connecting the second USB device.

    After removing the Symantec software I then uninstalled and reloaded the Acronis application. Again, both USB devices connected without issue. I have yet to reinstall the Symantec application. I will do so after obtaining the latest version.

    As an aside, when I first updated Windows 7 to Windows 10 the computer was loaded with Office 2013. After the upgrade none of the Office applications would load properly. I was instructed by the Microsoft Help Desk to uninstall Office and reinstall it as was instructed with the Symantec and Acronis software. This corrected the issue with Office. I mention this because I would expect such issues with 3rd party software such as Symantec and Acronis but I was surprised that is was an issue with a Microsoft product such as Office.

    Thank you for your assistance in resolving this issue. It is greatly appreciated.

    Cheers!
