    The latest attached DMP file is of the CRITICAL_OBJECT_TERMINATION (f4) bug check.

    This indicates that a process or thread crucial to system operation has unexpectedly exited or been terminated.

    We have little to no information other than this, so detective work will be necessary.


    1. Uninstall DeepFreeze.

    ^^ Samsung printer driver dated from 2005 which is way too old to work with Windows 7. Check for a W7 driver for your printer - Download Center: Download Software, Firmware, Drivers & Manuals | Samsung

    If not available, uninstall the printer software and disconnect the printer.

    4. If you're still crashing after all of the above, please enable Driver Verifier:

    Driver Verifier:

    What is Driver Verifier?

    Driver Verifier is included in Windows 8, 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, Windows 2000, Windows XP, and Windows Server 2003 to promote stability and reliability; you can use this tool to troubleshoot driver issues. Windows kernel-mode components can cause system corruption or system failures as a result of an improperly written driver, such as an earlier version of a Windows Driver Model (WDM) driver.

    Essentially, if there's a 3rd party driver believed to be at issue, enabling Driver Verifier will help flush out the rogue driver if it detects a violation.

    Before enabling Driver Verifier, it is recommended to create a System Restore Point:

    Vista - START | type rstrui - create a restore point
    Windows 7 - START | type create | select "Create a Restore Point"
    Windows 8 - Restore Point - Create in Windows 8

    How to enable Driver Verifier:

    Start > type "verifier" without the quotes > Select the following options -

    1. Select - "Create custom settings (for code developers)"
    2. Select - "Select individual settings from a full list"
    3. Check the following boxes -
    - Special Pool
    - Pool Tracking
    - Force IRQL Checking
    - Deadlock Detection
    - Security Checks (Windows 7 & 8)
    - DDI compliance checking (Windows 8)
    - Miscellaneous Checks
    4. Select - "Select driver names from a list"
    5. Click on the "Provider" tab. This will sort all of the drivers by the provider.
    6. Check EVERY box that is NOT provided by Microsoft / Microsoft Corporation.
    7. Click on Finish.
    8. Restart.

    Important information regarding Driver Verifier:

    - If Driver Verifier finds a violation, the system will BSOD.

    - After enabling Driver Verifier and restarting the system, depending on the culprit, if for example the driver is on start-up, you may not be able to get back into normal Windows because Driver Verifier will flag it, and as stated above, that will cause / force a BSOD.

    If this happens, do not panic, do the following:

    - Boot into Safe Mode by repeatedly tapping the F8 key during boot-up.

    - Once in Safe Mode - Start > Search > type "cmd" without the quotes.

    - To turn off Driver Verifier, type in cmd "verifier /reset" without the quotes.
    ・ Restart and boot into normal Windows.

    If your OS became corrupt or you cannot boot into Windows after disabling verifier via Safe Mode:

    - Boot into Safe Mode by repeatedly tapping the F8 key during boot-up.

    - Once in Safe Mode - Start > type "system restore" without the quotes.

    - Choose the restore point you created earlier.

    How long should I keep Driver Verifier enabled for?

    It varies, many experts and analysts have different recommendations. Personally, I recommend keeping it enabled for at least 24 hours. If you don't BSOD by then, disable Driver Verifier.

    My system BSOD'd, where can I find the crash dumps?

    They will be located in %systemroot%\Minidump

    Any other questions can most likely be answered by this article:

    Re: BSOD on win7 x64 when some one else trying to connect to my router's network

    Thank you Patrick for your time and help, that means much for me

    as for the CRITICAL_OBJECT_TERMINATION (f4) BSOD I had this several times by now after I noticed a high CPU usage from a process called "audiodiag.exe" and after BSOD rebooting it's happens that the audio is not working until re-installing my audio driver!.

    So I think it's an audio driver error, and unfortunately there is no updated driver released for now.

    Would you please take a look at the DRIVER_CORRUPTED_EXPOOL which gives me 0x000000c5 error and it's the main annoying problem and lets save CRITICAL_OBJECT_TERMINATION (f4) forward by now until the main stress goes out.

    Thanks again a I appreciate it.

    Re: BSOD on win7 x64 when some one else trying to connect to my router's network

    My pleasure!

    Rather than analyzing the 0xC5, I am going to hold off on that, and the best thing to do right now is to enable Verifier as I recommended as that will give us a good amount of info.

    Also, be sure to work your way through steps 1-3 first!

    Red face Re: BSOD on win7 x64 when some one else trying to connect to my router's network

    Hello Patrick
    sorry for the late reply I had to finish some company work.

    any way I've just uninstalled Deep freeze and Ultra iso.
    And tested other computers on work's network to connect and there is no BSOD on my laptop! ,
    so I tried to browse "Network" from the left explorer tree on my laptop which is my first time I can get access to other computers from my laptop without a BSOD error (you can tell that "Network" button was a -critical keep out- area for me
    and nothing shows up as an error !!

    Thank you very very much for your help, I will try today to access my home network when I get there and get my other laptop log in and see if BSOD problem still exists and I'll let you know if the problem solved as I hope.
    Thanks again my friend you are such a great help.

    Re: BSOD on win7 x64 when some one else trying to connect to my router's network

    Hello again Patrick,
    Good news:
    the problem is fully solved I did a passive testing last night and every thing was just fine.
    Thank you Patrick you are a life saver !, so what causes this error the UltraIso or DeepFreeze?
    as for the UltraIso I can go along without it, but not the DeepFreeze because this is the main work laptop I use it for programming and DeepFreeze is a good choice for me rather than using Virtual machines, so do you suggest installing a newer version of DeepFreeze ?!

    and BTW the audio problem happened every time I rebooted and the process called "audiodg.exe" located in System32 folder,
    I'll try to update my sound driver and see what happened, and report it here..

    Best regards,

    Re: BSOD on win7 x64 when some one else trying to connect to my router's network

    Glad to hear, it was very like DeepFreeze. Try a newer version and see if it stops, but if the crashes come back, you'll unfortunately need to find an alternative. Anyway, marked as solved! Please let me know if a new version of DeepFreeze works, though.


    Mazen and jcgriff2 say thanks for this.
