A few things you can try.
First unplug the power from the box and the monitor or flat screen, With switch mode power supplys there can be floating voltages.
The ground yourself to discharge static to a water pipe or GND on a electrical device. If you have a wrist strap even better.
Then reseat all cards in system, generally I have seen this problem with the Video card not making proper contact. Also unplug the memory modules ans reseat them. If this fails to work I would suggest to default the Bios, there should be a round battery inside the PC and generally there is a BIOS reset jumper near it, apply this with the power unplugged.
If this does not work I would then suggest to disconect the hard disk (S) from both power and PC, as well as the cd rom and floppy disk drives and all external devices except keyboard and mouse.
If this fails then disconnect the power cable going to the mother board and there is a secondary cable on newer machines. The apply power to the power supply only. Discoonect and reconnect to motherboard and reaply power, try to power up.
If all above fails I have seen where a power switch is stuck or the reset button is stuck you could try disconnecting these headers make sure you know where to reconnect them.
I doubt its power supply as you are getting power up, there is a safty system in the supplies that will not allow them to power up unless there is a voltage back from the mother board.
Are you getting any post beeps when you power up ??
It never gets farenough to post. All that happens is the pwr supfan spins,leds flash and supply shuts down.I will try reseating the boards as well as isolating the supply.
