Yes Wheel mouse, old Scroll mouse with rolling ball and not the laser mouse. –  Harish Kurup Jul 25 '10 at 15:45

If no,change the mouse because,it is most probably wheel mouse who is culprit, because the sensors of your wheel mouse's scrolling are out of order.

but when i use browser, and when the scroll bar appears(like in case of Google search, or Youtube..) the scroll bar run's on it's own.. going up and down... with out any event by mouse.. might be a case of Virus(Wild guess ) i think.. I will Try as you said and Let You know... –  Harish Kurup Jul 25 '10 at 16:30
    
yeah! the Mouse was out of order.. need to change... thank you @Mr-Right –  Harish Kurup Jul 27 '10 at 5:43

As you did a reinstall...

It must be your mouse or the hardware in the computer, to identify which one disconnect the mouse.

  • If it still occurs, it is the hardware in your computer, you might need a new mainboard.

    You can try to disconnect other hardware to see if those might be causing it.

  • If it is gone, it is your mouse. You can try inspecting the sensors or just buy a new mouse.

Although unlikely, I would recommend checking your keyboard too...
