This is really weird to me so let me explain.

Here's my new computer system.

Here's my problem.

I do a lot of work and browsing on the computer with no other source of noise present. When scrolling up or down on a webpage, there is a slight but very high pitched noise than comes from inside the tower as soon as you stop scrolling.

I thought it was my monitor at first as it sounds like when you turn the brightness on high. Unplugged the monitor and still had the sound.

So with the monitor off, I could use the scroll button on the mouse and make the noise. It's a usb cordless so I unplugged that and used the oem mouse. No luck.

So I'm figuring maybe the video card is having troubling running 1440x900 so I downgrade the resolution and switch to less colors. No luck.

Here's where it gets interesting. Vista has three power modes. Energy star, Power Saver and Performance. I was using Energy star. So I switched to Performance and the noise got louder and stays in sync with the blinking orange light on the front of the computer and is there regardless of what the computer is doing. I switch to power saver and the noise is gone.

Power saver mode is useless to me. Everything runs slow. In the other two modes, the noise drives me nuts.

Is there something I'm missing here?

Thanks in advance for any help.
