"Verify that the power supply needs replacement. The most obvious clue is that the system will do absolutely nothing when you hit the power button. If there is no sound and no monitor activity of any kind, the power supply has probably died. While this can also be caused by a faulty switch, it is usually the result of a burned-out power supply. To verify it is not the motherboard giving the problems, take a paper clip and insert it into the green and black terminals of the power supply plug after it is removed from the motherboard of the computer. Press the power button on the computer, if the fan spins inside the power supply, the motherboard is the problem. If the fan does not spin the power supply is dead. Another obvious clue is smoke or an odor of burning electronics, which will often (but not always) be noticed in a system that does absolutely nothing when you try to start it up."
