I have this Microsoft USB mouse which is unstable with pointer and is flickering a lot. For example, when I open Firefox or other browser or any other text editor, the vertical scrollbar on the right hand side goes from bottom to top and forces it to stay on top. Same happens with any other app which has vertical scrollbar and due to this unstability mouse pointer forces me to stay at the top. Mouse pointer also moves randomly without touching it. I checked to see if it's due to some process and removed svchost.exe which was taking more load, removing it from task manager temporarily resolves issue but it keeps on persisting.
Is it issue of USB port or mouse has reached it's end of life cycle ?
