Subject pretty much explains whats happening. I havent installed any new hardware. This started about a week ago. The high pitch noise is pretty faint, but changes as I surf the web. I can say when I hit any menu on the screen that either contracts or expands, the pitch changes tone.
I have the onboard sound disabled, no sound card installed, and I'm using the Creative Labs Sound Blaster Arena USB headset.
