I've got a Logitech Gaming-Grade MX518 optical mouse, and it keeps dying on me at random times. It usually only dies while playing games. Ive updated the mouse and video drivers and this hasnt solved anything. Sometimes it will die over and over again sometimes it will only happen once in an hour span. All ive had to do is unplug and plug it right back in but still this can be quite the annoyance when playing a game. Any help or suggestions would be greatly appreciated thanks.
