    At completely random times (or so I think so) I get the BSOD with the KERNEL_SECURITY_CHECK_FAILURE.
    I have updated all my drivers, updated windows, reinstalled all my drivers, but still no luck.
    When I use the Driver Verifier Manager to find unsigned drivers I find two files: atikmdag.sys and atikmpag.sys I do not know how to fix that.

    I don't know what to do.

    These files are part of the AMD graphics driver package. I think it would be best to completely uninstall the graphics drivers and then reinstall them using the latest driver package from AMD. Use Display Driver Uninstaller to completely remove everything, then get the latest drivers here.
