Something nearby is throwing RFI or EMI or both into your power supply. Moving to different outlets didn't help, so whatever it is sounds industrial, throwing junk into both sides of your supply. I'd get a transformer balanced 55-0-55 AC supply; whatever is corrupting your power will be stopped by that. Not cheap, but it works. Traditional noise filters would be a waste of time and money.
