Doing some reading right now about desktop computers it mentions that the power supplies monitor the qulity of DC voltages it supplies to the rest of the PC. If this voltage drops below an acceptable level, the power supply unit lowers the voltage to the motherboard. If so, the computer simply resets itself and begins computing again when the voltage returns to a suitable level. Is that saying it is rebooting, or is it saying it is putting the process or computer on hold until it gets the level to the proper voltage? And it is also saying that the voltages are +12, +5, -5, and -12. Are they no longer using 3.3V?
