Try disconnecting the bleeper. I get the same thing through my onboard sound system. It was annoying enough that I spent $ on a sound card even though the onboard sound had all the features I needed.Comment

Re: buzzing noise from MOBO
Are your speakers close to the tower, or does it have a integraded speaker (to play music and stuff i mean,) if so, it might be that the speakers are turned all the way up, so you are hearing the noise through the sound card on your motherboard.

My Dimension 3000 does that, but it's barely audible. I think it's normal though.Comment

Re: buzzing noise from MOBO
Mouse is usually on +5vsb in standby and on +5v during op by way of a switching IC.
Some may use +5vsb only. (Not sure.)
- USB or PS/2 doesn't matter.
That's done so mouse or hot-keys can wake system.
May be +5vsb or +5v problems in power supply.
Flyback transformer for +5vsb could probably make that noise.Mann-Made Global Warming.
