Audio Interference

I keep getting the most annoying interference via my speakers. It started some time ago for no particular reason. whenever I scroll the screen, move the mouse or type anything I get this faint but audible 'roaring/humming' sound it also occurs when on a website there are animated graphics My system uses WinXP, onboard sound via the Asrock dual-SATA2 mobo I have an LCD display, Logitech wireless keyboard and mouse and BT Voyager wireless modem (connected via ethernet). I've updated all the drivers that my system uses but have not updated the BIOS as I can't see why I should need too. I've tried moving the speakers, the k/bd/mouse transmitter and switching off the Voyager.

Sounds a bit like lack of filtering on one of the power supply lines (5v or 12v).
For a trial I think I would beg or borrow a cheap audio card to plug in and try instead of the on-board audio. Otherwise it's a MB job, very expensive ! Good luck.

Thanks for the reply. But I've a feeling it's to do with my speakers. I've just tried my headphones using the same port and the noise goes away. Looks like a new set of speakers required I guess.

Mains powered speakers? Move the leads around.

Tried that. Anyway I was trying to find an excuse to upgrade my speakers :)
