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 :-
[HR][/HR]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:

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.

[HR][/HR]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`0000[B][COLOR=#0000FF]1e00[/COLOR][/B] 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

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 ^_^
