    Both errors are 0x0000007E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
    A system thread generated an exception which the error handler did not catch. There are numerous individual causes for this problem, including hardware incompatibility, a faulty device driver or system service, or some software issues. Check Event Viewer (EventVwr.msc) for additional information specifically yeallow triangles and Red Xs.

    They only cited OS driver dxgnns1.sys but in the dumps there is list VIDMM_SEGMENT which is a Microsoft DX bsod and usually caused by the vid card and DX conflicts. What DX version do you have installed?

    Overclocking will cause DX bsod's. Are you oc'ing the vid card?

    Uninstall direct X and reinstall it.

    Latest version of your video card drivers installed? If not I suggest doing the following...

    1. Download Driver Cleaner Pro or Driver Sweeper (both have free versions; make sure the version will work with your OS) to your desktop screen and install.

    2. Download the latest diver(s) for your video card but don't install them.

    3. Uninstall your video card drivers and reboot your PC into Safe Mode. Run Driver Cleaner Pro or Driver Sweeper. If it doesn't find any video card drivers that is quite okay.

    4. Reboot and install new video card drivers.


    Also, open the Run box and type dxdiag and click OK
    If it asks you if you want to check for signed drivers, let it check
    Click on the System tab and at the bottom it should tell you which version you have

    The error is 0xA and these are caused by either hardware or drivers attempting to address a higher IRQ Level than they are designed for resulting in system crashes.

    Unfortunantly it only cited a Windows OS driver as the cause and OS drivers are usually too general to be of much help.

    However, in the PROCESS_NAME section of the minidump the steam executible was noted (steam.exe). I am not saying this is your issue but you have mentioned a number of your issues occur while gaming plus another piece of information that there is registry issues comes into play.

    I am not familiar with Steam at all. Is there a way to disable or uninstall and then reinstall without too much hassle?
