Mouse stutter/freezes for a split second.

Hello there I need help with my mouse.
The problem is whenever im doing some thing on desktop the mouse just stutters for a split second. Once it even disconnected and reconnected after 5 seconds. After that I changed the USB port it was plugged into. I changed it from 2.0 to 3.0 (not that it did much) but I did it incase the port was broken. After I changed the port the "stutter" still appears.
It started happening a couple of days ago 2-4. I might have gotten a virus because one day it was normal the other day its broken.
Today I reinstalled windows 8.1 and downloaded new drivers for the mouse. Yet no luck.
Now the strange thing is. I dont think I have experienced this in any games. I play Counter Strike Global Offensive and no stutter there.

Okay. So I went into CSGO and just kept shooting. After a couple of mins the mouse "stuttered" BUT. I think its the mouse disconnecting rather than " freezing" Because while it was stuck. I couldnt use my left mouse or any other button on the mouse. So the problem is that it dissconnects for a couple of seconds and then reconnects...

 

UPDATE: Tested on my old Razor Deathadder and it works perfectly. The problem was with Sensei. /Close
