Static Noise from Speakers

Hi All,

I didn't change a thing in my computer for 2 years now and one morning when i turned on my speakers I started to hear this annoying static sound, even when nothing was playing. I disconnected the speakers and connected earphones and they too emitted the annoying static sound. Then I noticed that the static has some sort of a "pattern to it".
I disabled the network adapter and the static is gone.
However as soon as I enable it the static returns.
I tried to replace the ethernet cable, but it didn't solve the problem.
It's not the speakers because headphones emit the same noise and I don't think it's the onboard sound as well because when the network adapter is disabled it works fine.

Would be glad to hear your ideas for a solution.

yes this worked for me thanks a lot... i woke up this morning with the same problem... i just turned down my CD Player Volume. I don't know how this may effect me later though. All i know is that noise is gone!!!!
