  1. I just bought new mobo, p4 and psu. when i installed everything and tried to boot nothing happened. both the psu fan and the cpu fan started but nothing else. the monitor wouldn't even reconize that the computer was on. Ive double checked all the connections and they are fine.

    the only thing that concerns me is the psu connector is 24 pins and the mobo is 20 pin but i was told it would hook up fine just wont use the four extra pins.

    I have no idea what to do now any suggestions

    is the 4pin atx12v line connected to the motherboard.? you should go over the motherboard's manual for installation and make sure there wasn't a spot you messed up or forgot.

    the 4 extra pins are removable and i thought they could be connected to the other atx 4 pin connector but they do not fit and there is no where else on the mobo for it to connect.
