Usually the BAD_POOL_HEADER BSODs are caused by some malfunctioning driver, but no driver is found to be failing there. Moreover, some of the BSODs are saying that those are caused by memory corruption.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If memtest does not show any error, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Let us know the results, with the subsequent crash dumps, if any.

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 internal pool links must be walked to figure out a possible cause of
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: fffffa800260d000, The pool entry we were looking for within the page.
Arg3: fffffa800260d600, The next pool entry.

ran memtest about 8 cycles and did not have any errors

ran driver verification for 24 hours with no BSOD's
(in one of the steps it says to check all drivers that are not from microsoft, however all my drivers on that list was from microsoft corporation)

do i need to run the driver verification longer until i get a BSOD?

It means that Driver Verifier was not properly applied. Try it one more time.

Driver verifier catches the display driver as failing.
Code:
BugCheck A, {0, 2, 0, fffff80002a96a55}
