New built comp won't start!!

I recently bought a
Cougar Solution case
Asus P8Z77-V LX Motherboard
Intel i5 Processor 1i5-3750K
Ultra X4 Modular 750 Watt ATX Power Supply
GeForce GTX560Ti (EVEA)

I plugged the motherboard in with the power supply and the processor, but when I try to start it up nothing happens the fans dom't move the screen is blank. My friends who knows a little about comp booted it to where the power fan spins for 2 secs then stops and the Intel fan just budges but nothing else.
My back is against a wall and I son't know what to do. Please help.
