I have just finished building my computer. The computer isnt booting up. I have tried pressing the power button. When I plug the computer in, the ledon the motherboard lights up, but if I press the power button, nothing happens.
when I turn on the computer, the fans, and the lights turn on for half a second, then the whole computer turns off. After that I cant even get the fans to spin if I press the power button unless I turn the power supply off, then wait till the led on the mother board turns off. Then when I turn the power supply on, I can turn the lights and the fans on for half a second. All the lights and fans turn on exert for the power and hhd leds. Help!
