I need some help please . I have noticed for the last 2 months that my mouse is acting strange lagging and some times just going all over the place . I have a logitech laser mouse I have the same problem with a regular mouse as well ( a cheep o from wallmart ) . What could be causing this ? I DL and even installed software and still this mouse issue is killing me ! Any thing I can do to fix this ? That is without having to reinstall Win OS . Thank you for your time and help in this matter .
