So I have a strange situation. I have a HP 6200 desktop (its got an integrated Intel 82579LM NIC) running windows 10 pro with nothing but Plex installed and a couple of shares for transferring files to and from. 

About every 2 weeks (although its starting to get a bit more frequent) this machine will kill DHCP on the Ubitquiti Edge router.  Now I know it is this machine as while this machine is in fault condition even a reboot of the router will not restore DHCP, as soon as I unplug this machine, reboot the router, DHCP works fine. 

Strangely enough when inspecting the logs on the PC, event viewer events all stop being recorded when the issue starts, then only come back after a reboot, PC is unresponsive until a reboot.

I have checked every log possible, both on the PC and router and nothing, I have assigned a static IP address instead of DHCP, just cause I could... every and all updates I can find have been applied, and my googling has revealed much...

My first plan is to rebuild the PC from a fresh W10 build, as I did find one web site that said there was an issues when upgrading from windows 7 to W10 on these machines , however as this is already a fresh W10 install I'm thinking that should not apply, but one never knows.

So while I will embark on the rebuild, any ideas or suggestions would be appreciated, as should this issue persist after the rebuild....
