    I just installed a new power supply in my computer today because the old one was too loud. Randomly today the computer just shut off. When I try to turn it back on the fans just move for like a 1/4 spin the computer does not power on.

    So what do you think it is?

    Have you tried reinstalling the old power supply to see if it works again?

    Power Supply's bad.

    Happened to me before, (Although it was a old power supple that did that), and after I got a new one, It worked fine.

    No not yet I guess I should do that. If it is the new power supply I will be mad that it was doa.

    Its a Corsair tx750w if anyone is interested.

    Unplug everything from the power supply except the main motherboard power and a single hard drive. See if the hard drive spins up and everything.

    What's the wattage on the PSU?

    EDIT: Just saw you put the model. Alright, 750 watt should be more than enough for almost any setup. Do what I previously noted and let me know what happens.

    I'd rather see it be a problem with the power supply than with the actual computer.

    There is nothing wrong with the computer. A power supply will spin up and supply power to components whether or not it's hooked up to a computer. I've actually made an iPod charger using a optical drive motor being powered by a computer power supply.

    Do whats been suggested, unplug everything except power to the motherboard. You might have too much inside the unit for the power supply to handle. The new one you put in is it the same wattage as the other one?

    No the new one is 750 watts while the old one is 500 watts.

    Glad to say it was just a loose connection on the mobo. 12 volt rail was the culprit.
