A system run-down: the temperature control circuit (CPU / GPU / EC / SB / IO), heat
B trigger a momentary power failure: over-current circuit (capacitor, MOS tube, IC), beginning with the burn-in method is lower than the rated voltage.
C components caused by the power-down due Weld: from signal to start (power management IC, inductor, capacitor)
D PWM Power IC: voltage with the oscilloscope waveform suspicious, to see whether over voltage or under voltage.
