Speakers - can hear feeedback

hi there

i have got a set of standard usb speakers that plug into the on board sound card.

When iam using my wireless usb mouse or the computer is busy working away i can hear feedback through them.

i have also tried some other speakers but same result. i am using windows 7 , many thanks

USB into the sound card? Are you sure these are USB speakers?

The sound card will generally have a 3.5mm stereo jack socket. Do you plug into that, or do they plug into a USB socket?

That's likely to be due to poorly shielded components inside your PC. I had the same problem till I upgraded my motherboard (there's still noise, but it's much less noticible).

I was thinking of getting the Audio Xonar Essence soundcard, which has a very good signal-to-noise ratio and EMI shielding. Might be worth considering:

If you have a separate (not onboard) soundcard, you may be able to add some EMI shielding yourself:

Oh, and have you gone into the sound card settings and muted any sources/lines that you aren't using? The noise on my PC was terrible when I had everything un-muted.
