Been building my new computer and it has been a while since I have built one. Having an issue that hopefully someone can help me with. I press the power button and all the fans start and run for about 3 seconds and then all the fans stop. After about 3 seconds, everything starts up again and then stops after 3 seconds. It continues until I shut the power supply off. All the lights are lit up even when the fans are not on. I checked all the connections and everything is secured. The motherboard lights up but it just can't stay running.
Any ideas?
