Electronic devices, including computers, that become unable to /cold/
boot (and need a reset some seconds or minutes after power-up) usually
suffer from dry or leaked capacitors, either in the PSU or - I've seen
that more often - the voltage regulator on the main board. Dry
capacitors often look innocuous, unlike leaked ones that show brownish
stains (electrolytes) on the cap or underneath.
