    Windows 7 BSOD Stop 0xC2 - ntoskrnl.exe

    The above crash typically indicates a device driver conflict, but yours does not indicate which driver and blames a Windows process. It could still be an underlying driver, but it may also be Windows corruption. Additionally, your other crash blames audiodg.exe.
    • See Fix: Audiodg.exe High CPU Usage for the audiodg.exe issue.

    • If you are overclocking any hardware, please stop.

    • Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log.
      For any drives that do not give the message:
      Windows has checked the file system and found no problems
      run disk check again as above. In other words, if it says:
      Windows has made corrections to the file system
      after running the disk check, run the disk check again.

    • Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

    • An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
      a. Backup your system and user files
      b. Create a system restore point
      c. If you do not have a Windows 7 DVD, Create a system repair disc
      d. In Windows 7:
      • Click the Start Menu
      • Type verifier in Search programs and files (do not hit enter)
      • Right click verifier and click Run as administrator
      • Put a tick in Create custom settings (for code developers) and click next
      • Put a tick in Select individual settings from a full list and click next
      • Set up the individual settings as in the image and click next
        Attachment 209661
      • Put a tick in Select driver names from a list
      • Put a tick next to all non-Microsoft drivers.
      • Click Finish.
      • Restart your computer.


      If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.

      Thanks to zigzag3143 for contributing to the Verifier steps.
      If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
      The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.

      When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
      verifier /reset
      -> Restart your computer.
