Hear how to "work the computer" why?

When to move for example a mouse, or put the files on Boxing archiver, then there is a crackling in the speakers, or whether it leads, is unclear. But, if you restart the computer, then going into BIOS, no sounds, no, and to download the audio driver in the system too, no outsiders, no sounds. Read on Habrahabr advised to turn off PC BEEP turned off, but the situation has not changed, still "the sound of the computer" is. Anyone with these have faced?
PS Line-In is also turned off, tried 2 different driver

Check the same thing with headphones. If the problem is just in the speakers, then the wire going to the speakers works as an antenna and pick up hum, and then the amplifier built into the speakers amplifies it.

In this case, it is solved by replacing the wires on the shielded. Sometimes it is enough simply to put it differently, away from the system unit.

put the filters on the wires going to the speaker. changed conder on the boards. but will not fundamentally.
between the beeper and mikroshemka audio codec the relationship is about the same as between St. Petersburg and Khabarovsk.
option 2: just shitty circuitry in the Mat.Board. try to put a good USB-zvukovuhu on 2метровом USB cable with a filter on the ends.

Because it is cheap, simple and not too high-quality sound card.
Soldered it to the Mat Board, and constantly catches lay.
Buy high quality sound card or put up with the situation.

I have been there + just constant noise. Helped external sound card, now complete silence. About individual internal can not say, because the connector is, and place no free.

And I have right out of the system unit high frequency barely audible squeak happens when you move the mouse. Maybe someone knows what's the problem?
