So I am pretty certain I'm having a PC side issue which is causing my pings to spike once per minute. I have talked with my isp and other technicians for long enough now to have eliminated all of the expected hardware / modem / isp network issues. They've changed the fittings on the modem/router (it's a combination one) and checked all the numbers, got the signal under control because it was getting overpowered at first, scanned for the wireless channel with the least noise and set the router to permanently use the channel as opposed to auto-scanning every minute (not that I could see this affecting the wired connection anyways).
If I ping my router constantly (or any website, or run a tracert etc.) I will see a large spike in latency (up to 4000ms) once per 60 seconds, this only occurs when running my standard win7 boot from my SSD, if I run windows from another hard drive or from this SSD but in safe mode with networking the spikes do not occur at all. Other devices such as tablets and my phone do not experience the spikes on the same network.
Network drivers are updated, I have run malwarebytes, ccleaner, adwcleaner, roguekiller, combofix and removed everything they found. I have tried disabling windows firewall (I re-enabled when it did not solve the issue), I have tried a couple of network tcp optimization tools. Nothing has solved the issue yet, I have already asked on various networking forums and no one can figure it out.
I have tried closing all processes that I can minus the vital system ones which cannot be closed and the ping spikes still occur unless in safe mode with networking.
Any ideas about something in the registry or otherwise that could cause this?
