The Add/Remove Hardware sound keeps going off on one of my user's computers. He also says the Safely Remove Hardware icon shows up in the system tray suddenly. His computer completely freezes when this happens. The whole thing only lasts about 5 seconds.
It's random and I have not seen it happen. He only has his mouse and keyboard plugged into the computer. I moved them both to different USB ports. Same thing. I gave him a new mouse and a new keyboard. Same thing.
He's on a Dell Optiplex 740 with Windows XP. Does anyone know what causes this and how I can stop it? Please let me knowif more information is needed.
