    Hi Jarlotee & Welcome to the forums ^_^

    I have analysed your dump files and below has been provided an analysis of the same for informative purposes :-

    SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
    This means a hard coded breakpoint or assertion was hit, but this system was booted /NODEBUG. This is not supposed to happen as developers should never have hardcoded breakpoints in retail code, but ...
    Code:
    4: kd> .cxr 0xffffd000213adfa0;r
    rax=0000000000000000 rbx=fffff801d96ed2a0 rcx=0000000000000000

    Last set context:
    rax=0000000000000000 rbx=fffff801d96ed2a0 rcx=0000000000000000

    Code:
    DEFAULT_BUCKET_ID:  NULL_DEREFERENCE
    As we can see from the above dump analysis, the driver "BCKD.sys" is moving a NULL byte pointer from RCX Register to R9B register or we can say that it is trying to dereference (Check Default Bucket ID) NULL value which is not allowed.


    DPC_WATCHDOG_VIOLATION (133)
    The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL or above.
    Code:
    5: kd> .bugcheck
    Bugcheck code 00000133
    Arguments 00000000`00000001 00000000`00001e00 00000000`00000000 00000000`00000000
    The driver was running for 7680 ticks without response which caused the DPC to crash the system.
    Code:
    5: kd> knL

    0e ffffd000`211c8288 00000000`00000000 0xffffe000`aee2ac38
    We can see from the above stack that the Avast Driver acquired a lock on a resource and then an interrupt was called in but it did not respond which caused the bugcheck.

    Kindly follow the below steps -

    1. Please remove K9 Parental Web Filter.
    2. If the crashes still continue, kindly remove Avast using this **TOOL**.
    3. Kindly update Intel WatchDog Timer. See if you find it here (Probably a part of the Chipset Software) - Motherboard - SABERTOOTH X79 - ASUS



    Let me know how it goes ^_^
