Make sure all connections for the speakers are tight. Try moving the mouse and or speakers away from each other. It's definatly an interfearence problem.

To joe_aqs:

Thank you. I will try what you suggested when I am back home.....but, the PC set is a new one....
Do you think I should ask the store?

It wouldn't hurt to ask the store. Chances are they won't be much help. If you can isolate the problem and approach them with it, it would be better. Also, be careful where you have you speakers placed. Are they sitting on top of your monitor? ..or anywhere other than on a table or desk?

right click on my computer go to properties and then go to device manager see if there are any yellow circles with black exclamation points also see what model soundcard you have in here

This applys to my problem:

2. make sure that the mouse cable, the monitor cable, and the speaker wires are not twisted around each other or even laying beside one another.

So, you should get the points :-)

BTW, is this means the PC set is not so good?

Cheers.

User1,
No, it does not mean that it is no good.  All electronic devices throw off electromagnetic interference.  You can get shielded cables, but these cost more, that's why you get unshielded cables when you get basic components.  Actually, I've never seen shielded mouse cables, but you can get shielded speaked cables.

Do you mean that you have unwrapped the cables and now you don't have the noise anymore?  If this is the case and your problem is solved, you can accept my above comment as the answer.  Just look in the bar by the comment for the 'Accept this comment as answer' button.

Thanks

To magarity :

Yes, after moving the mouse cable to other place the noice dissapeared.
I just wanted you to answer my "BTW" question before I grading you (and adjusted points from 60 to 70).
Thank you. One of your comment will become an excellent answer in a second.

To all experts helped me here:

Thank you very much indeed for your helps.

See you in EE.
