Annoying problem "sound and freeze"

[jonathan_tijuana]

Every once in a while the sound that tells you that you plugged something (usb,firewire..) plays and the computer freeze, but the think is that i never plugged anything i just have mouse in the usb and i just formatted hd.
anyone has a idea of what is going on?
