ok, well i've tried 2 pretty new mouses and both work fine, untill 14 mins or so, then all of a sudden the mouse will turn itself off and the only way to get it to work again is if i take the mouse out of the computer and plug it back in, and even then it sometimes wont work ....i dont want to keep doing this, how do i fix this problem so the mouse will work for as long as i have the pc on
