- I will make a list of what you should do

- 1- Unplug the power cord from the wall outlet.( i'm assuming this is a desktop pc)
Disconnect the Monitor from graphics Adapter.
2- open the case ( touch the chasis for a while to disipate any electrostatic charge in your body)
3- disconnect every devices except the motherboard from the Power Supply( colored wires - red, yellow, 2 black, pulling the connector form de device end.( Memorize their places)
Make sure the Power button is properly connected to the power pin headers on the board( use the motherboard manual if possible)
Take the cards( if any) in the slots out( be carefully, try to keep your fingers far from the electronic parts ( read about ESD)).
don't touch the RAM.

4- connect the power cord to ac outlet.
5- turn on the pc
Do the Cpu and Power supply fans works ( or at least the power supply fan) ?
if the answer is no, try to test the power supply with another motherboard. and you will see which one is defective.
If the answer is yes:
- Turn the pc off.
- Insert one card( if any).
- Turn the pc on, works ? no ( the card is defective).
- turn the pc off.
do the same with other cards one by one.
- Connect the hard drive.
- Turn the pc on, works ? no ( hard drive defective) yes ( turn the pc off)
- Connect the CD drive
- Turn the pc on, (and repit the steps adding devices in that way till you find the defective one) Always turn the pc off before connecting anything.

Maybe i'm forgeting something, if you have any question i'll be glad to help.

Good luck
