MY COMPUTER WONT TURN ON  

the light on the motherboard comes on and the lan light blinks. the power button is connected to the right pins but nothing happens when i hit the switch. would it be the motherboard or power supply or??

Nothing happens, or you don't notice anything happening? If NOTHING really happens, well then, maybe you should make sure your PSU and mobo are properly connected, then make sure both are not defective, shouldn't you?
