Why would this happen,
Building new system (number of the same built and no problems – there is always the first time), everything was in place, Powered ON and speaker wire inside the care melted producing a lot of smoke around the system and inside the case. Checked again motherboard manual for front panel connectors and all according to the manual. Same system using same Motherboard and case built and no problems. Has anyone experienced this in the past (WHY does it happen). Thank you !

Duff speaker (short-circuited)?

Does everything else work with the speaker disconnected?

a load placed on it greater than it's capacity ie wrong connection? etc.

Yes - possibly the 12 volt supply with a direct short to earth. Speaker wire is pretty thin stuff.

Was the wire coiled?

Wire was Coiled, and there was a wire to be placed onto a case (but this is the same thing with other cases). Never happened before. Could it be that the speakers coil was short circuted.
State at the moment is NOTHING WORKS other than CPU fan. Suggestins ??

Not enough power from a sound card to melt insulation, even with a short circuit. More likely the leads are in contact with a PSU output. If nothing else now works, the PSU fuse has blown.

I you coil wires you are making a basic transformer that will produce heat! It's safe to loop wiring back and fourth, and use a tie-strap but if in a coil it will overheat and eventually burst into flames.

Look at the bars on an electric fire, wire coiled round a bar, heats up and does the job it was intended to do.

Same applies to any appliance, [IE:vacuum cleaner] or extension lead that is coiled in storage, always fully unwind before using. j.

are you talking about the system speaker? or normal speakers?
