If the computer is off and only the built-in speaker woofer is on, it's open input noise if the computer is on, it could be cable noise

Either the signal source, bad wires, or power supply of the amplifier can be easily eliminated.

Power supply. Look at the filters. Maybe the electrolytes have dried out or are of poor quality.

It is the interference i.e. electromagnetic interference or maybe the defects in your amplifier power supply, bad filters or in the signal wires, but it can all be fixed.

This transformer is close to the amplifier and its magnetic field gives off this buzzing.
