@aeva It's working now, so not needed, but one other cause of bluetooth problems can be usb flash drives. USB 3 flash drives can to emit interference at around 2.4GHz, which will mess with bluetooth, most proprietary wireless dongles and some wifi networks.
My favorite though is that the cushions in office chairs can make an electrostatic discharge when you start or stop sitting on them that can cause monitors to flicker. The ESD Association published a paper on it. :)
