I have an optical mouse. Apparently is from Weibo but in the mouse definition it doesn't specify the model. I bought it one or two months ago and it was perfectly fine, without any problems.
Now sometimes it is moving the cursor on its own, with no specific direction. It just starts moving randomly and shaking a lot, sometimes it stops. When I move the mouse the cursor stops, I have to lift the mouse and put it on the table again in order to start moving again.
Even in games, sometimes I control a plane in War Thunder and the crosshair just "teletransports" itself to another part of the screen. And not only in games, but also when I do others things like searching things on Google.
I have a mousepad, it has many colors such as white, black and red. Do these colors affect the mouse? It seems that the mouse becomes even more unpredictable when I move it on the mousepad. I put the mouse on wooden table and I experienced the same thing, although with less frequency.
What can I do?
My computer is a HP NOTEBOOK G62 with Windows 7.
