Question about Computers & Internet
For testing purposes, move the main speaker as close to the PC as you can. Roll the excess cable up into a tight circle. You are creating a "choke" and should help with the symptoms that you are having. If it sounds like the problem is diminishing, make note how the coil lays (flat or upright). Then turn it the other way, and note if it reduces the sound or not. If you get a noticeable improvement, then Radio Frequency Interference is being coupled via the input leads.
On the power lead, do the same thing. Move the speaking close to the power outlet, and roll the power cord into a tight circle. You should be able to hear a reduction in the noise. Make note of the position (flat, upright), and switch to the other position.
Whether it be the input lead, or the power lead, whichever one had the greatest effect is where a noise filter needs to go. Some electronic retailers (Radio Shack for example) sell filters that are designed to have the cord wrapped around and through. These are very effective. You will probably find that this type of filter will be needed on both the input as well as the power cord to the speaker system.
Another method of reducing the noise is to shield the cables. While they are coiled up in tight circles, try wrapping a small piece of aluminum foil around the circle. You should notice a drastic improvement if the signal is being coupled through the cables. Try the foil on both coils. If there is an improvement, then you might be able to use copper or aluminum braid as a shield. This method is expensive though, the braid is a bit pricy. To use it, you would feed the cable (one cable per braid) through the middle of the braid, and then ground the braid to the metal chassis of the computer. If noise is *still* getting in, then it is likely being coupled off the power line. A good quality AC noise filter designed for this purpose would be in order here. A local electronics shop may also be able to add on an inline noise filter to the power cable just before it connects to the speaker itself.
Post back your results, I enjoy noise issues, and have become pretty good at identifying source, and mitigating their effects.

My first thought is that it's the nearby radio station, and there's little you can do about it without trying heavy shielded speaker wires. This blog talks about different situations, and some may work- I've never tried it:
If you use shorter speaker wires, that might also help, but would cut into the stereo separation, but shielded or shorter are the most likely solutions I see.
Good luck, and hope this helps.

Hi! Have you tried using a different speaker? Try it for the current speaker may be prone to statics. Try using a different speaker and see how it goes. Hope this helps and thank you for using FixYa!
