We didn't even put a floppy drive in this machine in an attempt to avoid just that problem. I even removed the Dawn of War CD from the drive, in case the computer was trying to boot from it for some reason.

I had a similar problem a few months ago when the machine tried to boot from my mp3 player for some reason, but it wasn't hooked up last night. I thought at first it might be trying to boot from my camera, but clearly that was not the problem.
