Solution
something modified data in memory and corrupted it.
it can be a driver that continued to use memory after it gave it back to the system, or wrote beyond its memory space into some other memory causing corruption.

these are hard to find. Noramally you would run memtest86 to confirm your system memory is working as expected.

if that is ok, then you would have to start cmd.exe as an admin, and run
verifier.exe /standard /all
this will force windows to look for device driver programming errors. reboot and run your system until you get a bugcheck. With luck the bugcheck will name the bad driver.

use verifier.exe /reset
to turn of the checking when you are done.
the driver name may show up if you use whocrashed.exe or...

the driver name may show up if you use whocrashed.exe or bluescreenview otherwise you would have to copy the memory .dmp file to a server and post a link and have someone look with a windows debugger.

you might even have to change your memory dump type to a kernel memory dump. It would depend on the nature of the corruption.
