It seems to only occur when the processor/some component of the computer is not working. If I'm playing a game or a video or something then there is no sound. The second I stop what I'm doing then it starts back up again.
1. No bluetooth, can't be that.
2. It's not a buzzing sound that only occurs when I scroll or click.
3. I tried setting Powermizer to Low or Medium and that fixed nothing.
4. Turn off power management for USB and nothing happened.
5. Got my graphics card replacement and that didn't fix anything either.
Now I'm thinking its the coils people are talking about but why would they only vibrate when my computer is idle? It might be the processor as well.
Oh and one more interesting thing. There is no buzzing sound when windows is starting up and for the first 30 seconds or so I'm at my desktop. Then the sound beings. Also very important: no sound when I'm in safe mode. It must be some component that isn't active when in safe mode. Any ideas?
Seems just like mine. When it's not doing anything it starts. Here is one example: Scaning with Ad-Aware SE for spyware...scan complete and it's not doing anything else, the buzzing starts.
Changing the voltage of the CPU with the Centrino Hardware Control changes the sound of the buzz and sometimes completly stops it.
