The first thing to do is to look up which code it is. Does it show the code on the screen?

On a somewhat related note (no pun intended :lol: ), mine did a funny chime thing when the hard drive was failing. It would play the first two notes of the upward arpegio, followed by a normal chime and usual startup (if I happened to have a boot disk available ). I might try mixing together a mockup of it if needed...

Also, check your keyboard's working! If the power button's pressed (or damaged) then it can cause a chime of death, and might also explain the initial freeze (i.e. it got interrupted by the interrupt switch :lol: ).
