It literally takes ALOT to kill a CPU, they dont just go bad. Have you tested your DC Jack instead of the power supply? I work at a repair shop and frequently experience a bad DC jack or the I/O chip of the motherboard going bad. It could even be you tack switch that powers on your MOBO, If you have a multimeter you can test various parts of the MOBO after watching a few youtube videos to be sure the MOBO is in fact dead.
