I too had a similar, 'mystery' problem which I finally discovered was a Black & Decker powerpac charger which was generating noise on one leg of our house wiring. I hadn't used that' B&D drill in years and a fellow who helps me with jobs around the house must have found it unplugged and plugged it in again.
Nothing springs to mind. I'll wonder around the house and look at each socket just in case the kids have done something I'm unaware of.
I'll report back.
