BSOD on seemingly random occasions: BAD_POOL_HEADER 0x00000019

Up until tonight I've managed to crash out with the BAD_POOL_HEADER message fairly infrequently, it started happening a few weeks ago and at that point it was uncommon. Now it has happened twice in one night so far so I'm out looking for some assistance. The first instance tonight was while playing Minecraft, the second instance was in the middle of playing Battlefield 4.

This is my first time posting for help on these forums so if I need to include more information please let me know.

I've run the SF Diagnostic tool and attached the resulting .zip to this post.

BAD_POOL_HEADER (19)
The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.

the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arguments:
Arg1: 0000000000000020, a pool block header size is corrupt.
Arg2: fffffa8017b96100, The pool entry we were looking for within the page.
Arg3: fffffa8017b96120, The next pool entry.
