DPC Latency

Pulling my hair out trying to fix this. This is what it is like

I have used LatencyMon and got this result.

It does seem to be tcpip.sys, which is my Lan right ? i have tried a few drivers but nothing seems to fix it. Anyone any ideas ?

youtube link broken
under drivers tab are they all microsoft?

are you online gaming, that would explain tcpip.sys problem

edit : close down unnecessary apps ie chrome etc rerun test

looks like you're running panda antivirus etc, try uninstalling that

One thing that stands out to me is that you don't actually have your sound drivers installed. Why i say this is that in your "Device Manager" pic shows just a "High definition audio device" rather than Realtek device.

Might not be relevant but just thought i would point this out.

I notice it more when im listening to music or watching a video/movie. I will remove panda and see what happens. Thanks.

I will try that, thanks.

Ok, i uninstalled Panda, installed audio driver. I am still getting the Latency but it's something different this time, though I think it is related to tcpip.sys

I turned everything off and ran it again. It did take a lot longer for it to trigger, but still getting it. From everything I have researched, it seems to be a driver problem. I have the most updated driver for my Lan, going to try and look for an old driver see if that does anything. I have looked but cant see to find any old drivers for realtek.

This seems to have improved it! it's still spiking but not nearly as bad. Will continue to monitor it though. Thanks.

Spoke too soon dammit!

Have reinstalled windows and left everything on default with nothing installed, will see what happens when i run Latencymon now.
