Marduath and I were talking today and decided that the Windows XP default "bong" noise when something bad happens needed to be changed. So we picked out a new sound, and now my machine makes that sound instead (see attached file).
Here is how you can do it to!
Using Classic view
1. START -> Control Panel -> Sounds and Audio Devices
2. Click on the Sounds Tab
3. In the "Program Events" window scroll down until you see "Critical Stop"
4. click Browse
5. copy the sound file into the window and select it, click ok.
