The bomb error. Those are for a number of reasons. What does it say? I remember I had one of those messages on my Performa 550 last year I couldnt figure out what to do. I finally found out I had to restart with the shift key down (To disable extensions) and then get rid of a bad extension. What kind of Mac are you using? What OS? Usually restarting takes care of bomb messages but I dont know which one you have. Of course reinstalling the Apple System Profiler will probably get it working fine again.
Hope this helps
