the driver in the stack was \SystemRoot\system32\drivers\bckd.sys
\SystemRoot\system32\drivers\bckd.sys
this belongs to K9 parental web filter
the stack back trace was corrupted so you don't know if the corruption was cause by this driver or another driver corrupting its kernel memory.
you might consider: assume it was the k9 software and remove or update it or
start cmd.exe as an admin, then run
verifier.exe /standard /all
reboot and wait for the next bugcheck. windows will check for memory corruption by drivers and bugcheck the system at the time of corruption and name the driver in the memory dump.
note: use
verifier.exe /reset
to turn off verifier functions after you are done testing (or your system will run slowly)...
