I understood that sometimes the voltage from a fatigued (?),
overheated (?) PS may fail the mobo's bootup requirements (which can
be stricter re: voltage variations than running requirements) so
sometimes a PS has to cool down before the PC will reboot. So
particularly, sometimes a PC failing to reboot promptly is a symptom
of the PS not max healthy.
