note: I looked at three bugchecks each showed memory corruption.
you might want to update your BIOS, reboot and run memtest86 to confirm your memory works as expected.
----------
I kind of expect your problem to be related to your use of the razer overlay driver
C:\Windows\system32\drivers\rzpmgrk.sys Thu Apr 17 12:36:12 2014
but I can not confirm it with a mini memory dump. The driver did have a problem where it would corrupt memory in certain cases but it is hard to tell without debugging.
so fix some of the other issues below and see if your problem still exists.
you could also remove the razer overlay manager if you don't use it.

Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC
