You may have a speaker connected that the amplifier cannot drive. Your receiver is compatible with speakers with 6-8ohm rating, however, even though your speakers may be operating within that range they may also have low sensitivity.
With the receiver turned off, disconnect the power cord for a few minutes, reconnect and then power it back on. And while you're behind the unit, that would be the convenient moment to inspect your speaker terminals...check for cracks, evidence of arcing and any stray pieces of strand wire that can touch the chassis or other terminals. If any of those conditions exist then that can a root cause of the problem and will have to be repaired.
You must also ensure that all of the chassis vents are not blocked and the unit does not have another device on top of it that also generates heat as well. In any event, keep it cool.
After that, enter into your speaker setup menu and adjust your crossover to a higher point for whichever speaker you had the failure. This will help control the overload condition, if in fact, it is being caused by your amplifier ability to drive your current speakers.
If after all of the above is performed and the condition still exists, try speakers with compatible ohm rating but higher sensitivity.
