I do not how to make the .wav file used at startup random.
However, if you would like to change the .wav file, go to:
Start > Control Panel > Sounds, Speach, Audio > Sounds and Audio Devices > Sounds tab
Under "Program Events" you can assign a sound to pretty much any Windows event.
Maybe you could create a program that will choose this .wav file randomly, sell it to Apple, and then that would insure that Microsoft would include this feature in their next version of Windows!
There are some pinball sounds included with Windows. If you want to use them, after selecting a Program Event, browse to C:\Program Files\Windows NT\Pinball. You can even preview the sounds. I have had a lot of fun with those.
