Panasonic SA-HT640 acting weird

Our Panasonic Receiver, which also provides us with DVD, AM/FM, and AUX for Sound Surround has been acting weird. We've had it about 5 years now. While watching TV using the AUX function enabling the sound surround, the unit flips over to what sounds like DVD disc function without any input from us. Also there is this weird "Whirring" noise that is constant. If the receiver is bad are my 4 component speakers no longer usable?
