note: remove the web access control driver, it that does not remove the problem you will want to remove as many optional drivers as you can or learn to use the windows driver verifier.exe tool to do so basic tracking of the drivers and force a bugcheck when one makes a mistake.
(you should update as many drivers as you can first, but I think the indicated driver has a bug and should be updated or removed -- see below)
-------------
I just looked at your bugchecks I would think you have a device driver issue not a hardware issue.
I would start by removing
mwac.sys Tue Mar 04 13:47:13 2014 (Malwarebytes Web Access Control)
and see if your problem goes away.
you should also update Rt64win7.sys Wed Dec 26 09:17:50 2012 (realtek ethernet driver)
and athrx.sys Thu Jun 14 01:23:09 2012 (Atheros wlan driver, this driver depends on the updated chipset drivers for your USB ports)
