  • Question

  • Hi there,

    I keep getting Blue screen 1a every day. The error messages are all very similar as showing below. Can anybody explain what is causing the error, and the solution if at all possible?? I uploaded recent dump files to skydrive.

    Thanks in advance.

  • Hi,

     

    I would like to suggest you test the issue in Safe Mode, Clean Boot and Device Clean Boot to narrow down the possible hardware and software causes.

     

    Device Clean Boot

    =============

    Please unplug all unnecessary devices to test your computer's performance. In this situation, your system will only have the basic hardware devices and it should be more stable.

     

    If it is inconvenient to unplug the devices, we can disable them in Device Manager. Please refer to the following steps:

     

    1. Click "Start", type "DEVMGMT.MSC" in the Search textbox and press Enter. Please click “Allow” if the User Account Control window is prompted.

    2. Expand "Sound, video and game controllers".

    3. Right click on your Sound Card, select "Properties"

    4. Click "Driver" tab, click Disable (Disable the selected device). Click OK

    5. Please use the same method to disable other hardware such as: Modem, network card, CD-R drive. Please note some devices such as video adapter are not available to be disabled.

     

    Then, restart your computer. Does it still crash now?

     

    If the system is stable, we can re-enable the devices one by one to narrow down the root cause.

     

    Troubleshooting the BSOD issue can be time-consuming, you may also contact Microsoft Customer Service and Support (CSS) via telephone so that a dedicated Support Professional can assist with your request. To troubleshoot this kind of kernel crash issue, we need to debug the crashed system dump. Unfortunately, debugging is beyond what we can do in the forum. Please be advised that contacting phone support will be a charged call.

     

    To obtain the phone numbers for specific technology request please take a look at the web site listed below:

  • This is sort of an interesting error, 1a refers to
     
    # for hex 0x1a / decimal 26 :
      MEMORY_MANAGEMENT                                  bugcodes.h
     
    and the process is listed as the .Net Runtime Optimization Service,
    mscorsvw.exe. I'd recommend testing the memory to see if there are any
    problems with a tool such as Memtest86,
     
     
    If this tool finds errors, then you may need to replace one or more of
    the DIMMs in your system. Since you are receiving this error once per
    day, is the process name,
     
    PROCESS_NAME:  mscorsvw.exe
     
    listed by the debugger always the same?

  • Hi Mike,

    Thanks for the reply. I uploaded 4 dump files and if you check them you will find out different process names. I had tried windows memory diagnostic tool & memtest86 but none of them found any error. I even replaced the motherboard and reinstalled the system but I still got this 1a every day. It's really annoying.

  • Interesting,
     
    Have you tried verifying the protected OS files? This may help if there
    is corruption in the kernel executable (ntkrnlmp.exe) or one of its
    dependencies. This is done by executing
     
    sfc /scannow
     
    from an administrative command prompt. Also, are all of the device
    drivers and firmware up to the latest versions?
     
    Some of the drivers may be available through Microsoft Update. I would
    recommend getting BIOS and chipset drivers from the computer
    manufacturer or motherboard manufacturer, where other drivers can
    usually be obtained from their respective vendors. It is possible to
    determine from the Components node of the msinfo32 utility the vendors
    and devices that you probably want to look for updates for.

  • Hello !

    I have the same problem.

    My computer work since a few year and i try to resolved this error.

    I join two logs: SFC and COMPUTER.

    SFC log download link.

    My Computer log download link.


    After few day than my computer stay on, i'have turn it off for since night.
    The tomorrow, the computer restart 3x without show the boot screen.
    When the window loaded i'have the blue screen like the top message of S.R.
    The computer was very slow !.
    In the panel configuration, my graphic card got a warning icon.
    My printer is to be undetectable.
    Mouse and keyboard disconnected.
    Internet on lan very slow too.
    I'do a defrag, chkdsk, launch a antimalware and antivirus scans, ...
    I'm scary, my i7 work like a 486dx !
    And when it start, it restart automaticly 2x/4x before show the bios post.

    Microsoft Windows memory tests = Not error.
    Memtest = Not error.
    I'have updated my drivers.
    I'have rewrite the lasted bios.
    All temp is good.
    Removed all drives, graphic card, bios and mem are cleared, remove the static energy, unplug front card reader, ...
    I'have change the position of all memorys in bank channel.
    Nothing to do !

    Now, the performance had come back but the problem is already present !.
    I'have already the blue screen who appeare with a random time delay on windows.
    ( Signal ON but black screen on primary screen and BSOD message on the secondary screen).

    When i do a Reset, it turn OFF and restart 2x / 4x before show the bios post.
    My motherboard got 3 leds (tests before the bios screen); my computer reboot when the VGA_LED turn ON.
    I have a unknow lost packets with Google Chrome too, strange no !?.



    Memory manager can be due in the CPU...
    I will think remove and resock my CPU, maybe that a flat pin connector have a problem ?.
    I will change all hard drive.

    After all that, if the bug come back, i change my graphic card !!!.
