On one computer where I work we were having this problem, and disabling malwarebytes fixed it. Not sure what that was about, but it was a good straw grasp. What kind of network cards? I've only seen this problem with realtek devices. After installing a broadcom NIC in my HTPC the issue stopped, although shortly thereafter the problem stopped on both of my HPs also.
Are your system interrupts hogging all the processing power like mine was?
