Hi, I am having a strange problem. My PC mouse goes dead for a few seconds and then starts working. I have a Logitech G9X laser mouse which started having this problem and after a few days went completely dead. I then connected my old Logitech MX518 optical mouse which was fine for a day but later started developing the same problem. What may be the cause of the above problem? My PC is running fine expect for the above problem.
