The problem is that you applied power with reversed polarity....
Your power supply is toast, at the very least. It's possible the whole PC is reduced to a paperweight.
Rather than identifying wires by their color, it's a far better idea to refer to them by their function (+12v constant, +12v switched or ground).
Oh yeah. QUIT CROSSPOSTING!
