Hi. I am a newbie in electronic. I have a Compaq Evo PC, which has that long power supply unit with the standard 20 pins connector to the motherboard and the other 4 pins connector.
Recently, it developed an electronic fault whereby it powers on in an instant then it goes off.
I took it out and opened it, tried to discharge the main electrolytic capacitor first and it didnt indicate any high voltage, so i assumed it could be the capacitors which are faulty, changed them some new ones and still the problem was the same. it powers on in an instant, then switches off, any assistance please
