help me with mouse:<

ok i have an mx518, never had any problems but recently it does some weird stuff. For example, i hear a weird noise (usb removal noise) and it stops working and i have to reconnect it from the back and force the wire into the mouse more. Sometimes it shoots by itself before it stops working :x Tried with and without software but still same prob, any suggestions not contaning reformat or /kill irl would be much appreciated. :<

Yours faithfully, Kamz
