Issue with mouse cursor 'jittery'

[olly29]

Hey guys, as the title says I am having an issue with my mouse cursor feeling inaccurate/jittery. I notice this a lot as I play a lot of PC games and any small effect I notice quite a bit.
I have recently upgraded all my PC parts except for my GPU and the problem still persists (I had the issue before I upgraded).
I have tested numerous mice on my computer and they all experience the same jittery effect but when I try them on a different PC it does not so I have concluded that it can't be the mice. I have also tested mouse pads etc etc.
The only 2 parts which have not changed is my GPU and my 60hz monitor. Is it worth disabling my GPU and enabling my onboard graphics card to see if I can identify an issue with my nvidia GPU? If so how do I go about this?

This is my current setup, running windows 10 home:

Mobo: Asus Z270G Gaming Motherboard

RAM: 16gb Crosair Vengeance 2400mhz

PSU: Seasonic X-650

CPU: intel core i7-7700

GPU: Nvidia GTX 970

This is driving me crazy, hopefully I can get it sorted soon. Thanks guys!

Do you happen to have any other sort of pointing device connected to your PC? All mouse-style inputs get summed together to move the mouse pointer and if any one of them is 'jittery' then you get jitter.

Nope, just one mouse and keyboard. The jitter feeling is as if the DPI of the mouse is very inconsistent, it feels very weird with my mouse muscle memory. Sometimes I'll over compensate or undercompensate my cursor location.

I've had issues with jittery optical LED/laser mice and in all cases, the problem was simply dust either in front of the lens or between the lens and sensor. Since your mice work fine on a different PC though, that seems unlikely. I'd still check device manager to see how many pointing devices you have installed just in case.
