Computer makes a sound when I stand up from my chair?

[Papa Hogan]

The only things that come to mind as possibilities are that I have a webcam connected and that there's an Eco Light Sensor on the monitor. It's been doing it once in awhile for quite some time now. I'm using windows 7, if that matters.

Can anyone help me figure out how to turn off the notification that I've gotten up?

Turn the computer off before you stand up.
Problem solved.

Unplug the sensor and make sure that it is the problem.

NSA. Those guys rock! I'm glad we got such hackers working for us.

I'll try unplugging the camera and see if it goes away. It's really weird that I could set a sound to it that says "Goodbye!" when I stand up. Any idea which setting it would be so I could do that?

HAL?

(edit): I checked and found that the Eco sensor in the monitor has been off. I've saved 0.0 trees it tells me. That leaves the camera. The light on it hasn't been on, nor has it been used much lately. How do I find out which alert sound is being played?
