My speakers appear to be picking up a radio signal or something, when I turn the volume all the way down I'll get a radio channel. When the volume's up, the sound is fainter, but still there. It doesn't happen when I turn the speakers off.

Anything I can do to stop it?

Do they still do it when they're not plugged into the computer?

Most likely the radio signal is being picked up on one or both of the wires (mains and /or audio connection), and could probably be eliminated with use of snap-over ferrite beads like this:

Radio Shack type stores sell them (depending on your country of residence).

If it's the internal circuitry of the speaker amplifier picking up the radio, it's more difficult to deal with.
