Cant power new built computer when cpu is powered on?

i just recieved a brand new computer parts from this computer olympics (mobo, cpu, case, power supply, ram, etc.) and i put it together and for some reason i can power the mobo on and get the fans spinning only when the socket 775 cpu's little 4 pin power cable isnt in. not the cpu fan power but the cable from the power supply to the mobo for the cpu. do u think the cpu is bad? now it looks like after keeping it runing for 5 minutes, there is no power going to the board. they gave this exact parts to be used together in a computer competition so i would imagine the power supply is strong enough. its got to be the motherboard or power supply? what to do u guys think?

1. could be, also, are you sure your power supply is strong enough to supply your system?
2. i have a new gygabyte board that did the same. and it was because something was not connected right.
3. might not be connected right or the Power supply is not good (enough).
4. Are you plugging the 4-pin connector in the right way? It will easily go on incorrectly and it's hard to tell, that screwed me up for awhile.
5. What model Intel CPU is it and what model motherboard is it? Have you connected the power switch correctly. Just because the board gets power when you press the button doesn't mean it's in the right place. I connected the power button wrong once and the pc would always go on but would not post properly. Put the switch in right and all was well. Try that otherwise the board might be dead, there is a possibility that something might be wrong with the powersupply.
