This has been an ongoing issue since the computer was new. It is now about 7 yrs old. It did it at our old house, and our current house. The problem is, my speakers intermittently pick up radio broadcasts. Usually happens at night, but has happened during the day as well. This happens even if the computer is turned off. If I turn the speakers off, or unplug them, it no longer does it, but it will still do it even if the volume is all the way down. Any thoughts, or am I the owner of a possessed computer?
