i have a peg II g4 radeon 7500 agp speaker logitech z340 thanks for answers
the effect you describe has nothing to do with the dissortion problem (which was mostly noticable on peg1: music/sound was dissorted while moving windows for example).
The problem you have sounds more like a "very cheap case" with bad or no shielding.
You can do a few things to improve this: move speakers more away from your case, use better cables (also internaly, e.g. for the cdrom <-> board connection). Alternatively you also could completly shutdown unnneeded "inputs" inside the PegasosMixer, so you have less disturbing factors.
If I understand correctly, you can hear noise when loudspeakers are at a very high volume. I think your problem is a classic universal: General processing in your motherboard generates noise, which somehow filters out to your loudspeakers. You can actually "hear" any computer working with a simple domestic radio, depending on its physical position, and the frequency you are listening to.
