cool, in the non paged pool text file is the one of interest:

System pool information

Wfpn Nonp 9478631 (4157) 0 ( 0) 9478631 6066320960 ( 2660480) 639
NDNB Nonp 9477697 (4055) 0 ( 0) 9477697 758216800 ( 324400) 80
from this we see that the driver allocates driver memory but has never returned any.
now lookup the pooltag Wfpn and NDMB

My guess there is a error condition in your network driver that causes the other drivers to not free its memory resources.
I would update my network drivers, if that fails i would turn off the microsoft driver
using:
start cmd.exe with admin rights (windows key+x then A)
sc.exe config NDU start= disabled (this will config the service no to start on next boot)
reboot and see if your memory leak problem continues.
and we find the WFPN =netio.sys - WFP NBL info container

e22w8x64.sys Wed Mar 20 14:24:01 2013 looks like a killer network card driver
I think MSI will have the updatedriver for your machine
