Solved: bleeding Audio problem

[NEMO7]

Have Cambridge SoundWorks stereo speakers connected to the computer (desktop/WindowsXP/PentiumIV) and even though volume is turned down or off, there is music/sound/radio station? bleeding through from somewhere. It seems SoundWorks acts like an antenna and is picking up ambient radio waves. The only way I it stops is when I power off completely at night. Is there any way to block the noise/interference? Thanks.

Are these sheilded speakers specifically designed for computer systems?

Thanks for replying. In response to your question: Yes, the speakers are specifically designed for computers.

Problem solved. After calling Cambridge Sound Works, the tech informed me that ambient sound waves are being picked up by the sound system on the computer. So what's new!? I knew that much. Solution: reorient the base unit. Actually, I tried various positions, and since the unit was next to radiant heat base board (metal) which was acting as a conductor, I interposed a barrier between the two and that worked fine.
