I ran a Windows Memory Diagnostic test overnight - no problems were found. I've updated all my drivers.

Hello there!

Seems like the crashes maybe related to Network drivers since the stacks are pointing to X64_0x1a_41287_NETIO!NsiEnumerateObjectsAllParametersEx+6df I would recommend to reinstall NIC drivers.

(Driver    c:\windows\system32\drivers\netr28x.sys (, 606.00 KB (620,544 bytes), 10/06/2009 21:35))

(Driver    c:\windows\system32\drivers\athrx.sys (, 2.66 MB (2,791,424 bytes), 18/08/2012 13:55))
Uninstall Asus Utilities since it's notorious for BSOD
