Strange buzzing and squealing

[Sproutzy]

Hi,

My speakers keep making strange noises and it's really bugging me! It kind of changes between low buzzing and squealing noises, usually when doing CPU intensive tasks such as running Prime95 or playing a game, it also buzzes when I scroll on a web browser! It's not the speakers as the same noises occur through headphones.

Please help as this is most frustrating!

Heard of this before, if I remember correctly it's down to poor grounding.

As to fixing it, damned if I know how, sorry.
