I have a problem with mouse. It is unstable, sometimes work slowly, sometimes very inacuratly, sometemis it worrk more or less okay. It is a wirles mouse. I tried to updated drivers, I cant it says they are alredy updated. I cleaned mouse. I tried in on other computer, there it works OK. I buy new mouse, problem persis on this computer. I chaned setting (pointers speed, accuracy, and other seetting, nothing) helps. I unninstaled mous drivers complety. I try all possible USB ports. Same thing. Some times it work relativly okay for periods of time and then not. Sometimes coursor moves on its own even if mouse is still. Does anyboy have idea what eles can I try?
