this problem can also be caused by a power supply that has a weak standby current. the mains voltage may have dropped a bit due to high demand in the hood, and the standby current that was already weak drops to a level that the mother board cannot recognize. the standby current is always supplied to the mother board even when it is off, when you press the power button it lowers the voltage on the standby pin to ground signelling the power supplie to power up the main power. to many pci cards in a system that use the standby voltage eg. wake on lan nics and some video cards, ps2 mice and keyboards, can drop the voltage to much and stop a pc from powering down or up.
try and get a power supplie that has a larger standby current/
