|It sounds like you are using a wireless mouse. When you first have trouble with them, try replacing the batteries in the mouse. The wireless dongle should be (like a wired mouse) plugged into a rear USB port directly on the motherboard, not on any hub, expansion card, or many front ports. Sometimes front USB ports are not directly connected to the motherboard, but go through an internal hub that is part of a front multi-port expansion product. This hub might be the problem and may be overloaded or not good. You should use rear ports whenever possible, especially on devices you are rarely going to unplug and save the front ports for portable drives and devices you normally or periodically remove.|
