I have a Micro ATX computer with an Aopen MX46 mother board running an Intel Chip of unknown speed in a 478 socket.
When you turn the computer on with everything properly connected the power light blinks and the power supply seems to shut down. Checking the power supply with it disconnected from the motherboard, all the voltages are ok. With all peripherals removed and drives disconnected when the power switch is pressed the power on light blinks and the power supply shuts down. With the four wire, +12v connector removed the power stays on but obviously nothing else happens.
This seems to indicate a short in the motherboard or is it possible the cpu could be the problem?
