What would cause the power to kick off after about two seconds on my computer tower?

I’ve got a Compaq desktop computer, when I turn it on (the power button on the tower) the green light comes on, the fan starts up, then it cuts off. Could it be a problem in the “Motherboard”? I replaced the power supply because there was no power at all, now the power comes on for about two seconds. Any ideas?

    it sounds like it could be your motherboard. is it a stock compaq motherboard? If it is its probably what failed, you could probably get it replaced but depending on what you use you pc for you may be better off building a brand new one from scratch. just go to your local computer hardware store or micro-center or whatever you have, they’ll help you with every step!

    power supply………nm

    Also try dusting the thing out. If not the mother board might have shorted on account of being grimey seen it happen about a dozen times
