You're receiver is rated at 100W. Your speakers can't take this nominal power from you receiver, overheat, impedance goes way down and you receiver shuts down. You would have fried all your speakers long ago if it didn't. Get speakers rated at at least 100W nominal, 150 to be on the safe side and you will be smiling ear to ear.
