It's more than likely the motherboard needs replacement.

    See if there are any led lights turned on the mother board when power is applied to it. You may be able to check the power going to the mother board from the power supply by pluggin it in half way and taking a meter and checking for voltage being careful to touch the probe on one electrical post at a time.

No it is not neccassary to use a E-machine power supply if your previous one has become faulty. You can use any one as long as it has the required power rating.

Actually no, the power does continually comes in but, when stopped, the PS is in a state that could be assimilated to stand-by - only a small side circuit is continually operational.
