Getting error bad_pool_header on bootup Plz help (win8.1)

OK so every time I bootup I get this error Bad_pool_ header with the big sad face, then it says gathering information then restarts. This happens twice then brings me to the automatic repair screen saying would you like to restore?  This is all I know about the specificity on the error itself. 

So this it what I've tried (in no particular order) all without success: Restarting, Automatic repair, Refreshing, System restore, Removing all external peripherals and restarting, Running Hardware troubleshooter, Disabling antivirus, Booting win8 dvd and running system repair, Booting safemode and disabling all non-microsoft startups and services, Booting safemode and disabling all startups and services, Booting diagnostic repair via msconfig, and probably more that I can't remember (its been a couple hours)

I would really like to solve this issue without having to wipe the system so any help would be appreciated.

Systems specs available upon request 


Fantastic, thanks for the Kernel-Dump!


This indicates that a pool header is corrupt.

Pool page [ ffffc00000800000 ] is __inVALID.

It looks as if there's a driver causing corruption within the paged pool.

^^ It appears the driver causing said corruption is avgldx64.sys which is the AVG AVI Loader driver.


Remove and replace AVG with Windows 8's built-in Windows Defender for temporary troubleshooting purposes:
