Tighten all the Hots, Neutrals and Ground returns from all branch circuits in your breaker box. Be sure the ground bond strap in the box is tight too.

Do this with each branch circuit breaker OFF obviously.

If there are no ground wire returns, then you may have poor or corroded box to conduit (or BX) connections in your circuits. Maybe a open neutral in a circuit, which then relies on a poor ground return thru the conduit/BX causing the problem(s). Standard 3-lamp outlet testers can detect this.

Just some thoughts…
