    Just bought a GByte GA-P41-ES3G and fitted CPU Intel 430 LGA 775.
    CPU fan only spins a few seconds then stops. Nothing on the screen, no
    bios display. The PSU is a bog-standard 20 pin plus the extra 4 pin
    plug nr the CPU. Should I invest in a 24-pin PSU, would it make any
    difference? Do people use a 24 pin PSU AND the 4 pin 12V plug?

  2. Its difficult to figure out what you are doing.
    However, my guess is that you are using a 20 pin psu for a
    24 pin mb with the additional 4 pin cpu power plug.
    Yes, you have to use all of those.
    That cpu is capable of drawing 30 amps.
    Combine that with the north and south bridges
    and you will need at least a 500 watt psu.
    If you have a vid card, add another few hundred watts.
    If you overclock, add another few hundred watts.

    Make sure, that the four pin you're plugging into the ATX12V
    power plug on the motherboard, has two yellow wires and
    two black wires. The two yellow wires are +12V and that
    is used by Vcore to power the processor.

    There is another four pin thing you can plug in by accident,
    and it has four wires of different colors. You don't want
    that one.

    The 20 pin should work fine, to power a 24 pin equipped motherboard.
    The latch on the connector, goes on the same side as the latch
    fitting on the motherboard. Pin 1 of the connector, goes to
    pin 1 on the motherboard. The "shapes" of the nylon shell, help
    guide a correct fitting.

    Probably not an issue for your motherboard, but included for
    future reference. The latches are to be lined up.)

    It sounds to me, like the power supply is being overloaded,
    by something you're doing to it. That's why I'm suggesting
    verifying the connections. Maybe it's not your fault,
    and it is a bad, brand new power supply. But it doesn't
    hurt to check the wiring.
