PC mouse being floaty, input lag, problems

[germinatingx]

The problem I'm facing is my mouse being floaty/ slight microlags and input lags in my wireless mouse. I've never faced this problem before and its been a recent development. It's extremely annoying to play competitive fps games with this issue. I've tried cleaning my entire PC, deleting stuff for space etc. I recently switched to the razer viper ultimate which is a wireless mouse, from the razer viper(wired) mouse. My mouse is currently plugged into the USB 3.2 port on my motherboard. It causes slight input lag and micro lags at times. The PC is running smoothly and can handle most games with no problem. This mouse works completely fine with every other device, including my laptop (asus zephyrus g14), concluding that it isn't a mouse problem. I'm quite lost as I've looked everywhere and tried every solution, however, nothing seems to work. The input lag exists no matter how many mice I switch through and its quite annoying. The USB 2.0 ports make the mouse completely unusable with major delay and floating. This problem is only occurring with my mouse. My keyboard seems to be working perfectly fine(On a USB 2.0 port). My PC seems to be working perfectly fine with all games, including graphically demanding games, FPS seems consistent with mouse delay being the only problem My PC Specifications are as follows -

Hey, did you find the solution? I've found out that the power cables and usb cables inside the case on desktop have affect on the mouse movement.  but on my laptop I've yet to find what causing it, I have old Asus G753JT that I still play and use and the mouse input lag there always changing, even at my work place and in my home. so it's something very very specific to the laptop, something inside, I've been thinking it could be the Harddisk which needs EMI protection like we usually on laptops which I don't think I have. and because you say you have new laptop so it can't be because I had my laptop repaired 2 times, one time it because the gpu needed to be replace so it support Gsync and the second time was 1 fan stopped working. I am sure it can't be the motherboard replace because I didn't notice that at the time.
