    Computer randomly crashing (ntoskrnl.exe, atikmdag.sys, dxgmms1.sys)


    Hello.

    I am getting really tired of my computer crashing constantly. The main concerns are: ntoskrnl.exe, atikmdag.sys and dxgmms1.sys. I have fresh installed four times, updated all of my drivers and DirectX, too. Nothing helped.

    I have send my PC back to it's manufacturer 2 times, and they said it was fine. I have also run Windows Memory Diagnostics without any errors.

    It happens randomly, even though what I am doing on my computer (work, games, surfing the interwebs etc.)

    System specifications
    AMD Phenom X6 II 1090T
    AMD Radeon HD 6970
    8GB DDR3 RAM (I don't know the frequency)
    Windows 7 64-bit

    What should I do?

    Dumps attached,
    Oliver.

    In this order,

    Update your windows.


    Run SFC /SCANNOW Command - System File Checker you may need to run it 2-3 times to "fix" everything.


    Run RAM - Test with Memtest86+
    Leave it to run overnight.
