Background noise in Headphones

[OblivionMage]

I hear a background noise when using my (Zalman surround sound) headphones. It can change if I move the mouse, or switch application windows, but is always there. To lessen its effect I turn the 'wave' setting on my computer to full and then volume to only 1 or 2 so that it usually overrules the noise, but it is still audible :/

It has nothing to do with sound settings, I have changed all of my settings on my normal audio settings and SoundMAX settings, to no effect (Obviously without mic, etc...). I have unplugged cables / removed them from the back of my computer to no effect, and if I plug my headphones into the front jack of my computer I get the exact same thing.

Any other ideas? I have sort of moved around the cables in my computer (that could be interferring) but to no effect so far. I have heard that it could be a lack of rubber stoppers between mobo and case, cd audio cable from cd/dvd drive to mobo, PSU cables / unit itself, or faulty sound card.

I am trying to get a new sound card to solve the problem, but any ideas / others with this problem? :/

I've had the same problems with my speakers for my computer. Whenever I seem to move the mouse(when I'm playing WoW) I get a really drawn out, annoying buzzing noise. I've taken to unplugging my speakers :P
Anyone have some suggestions for us?

Buy new ones? get a soft Q-tip, and rub the outer and part of the inner input jacks with rubbing alcohol
