Except what you described has absolutely nothing to do with ESD. You did not discharge 10s of 1000s of volts of static electricity from your body through a component mounted on the motherboard. You spilled a liquid that shorted out two or more electrical contacts with a maximum of just 12 volts. Big difference. And actually, odds are it was probably closer to 5V. And it was probably your power supply sensing the short (and resulting excess current) that caused the PSU to shutdown, not your motherboard.
