Newly Assembled Rig Not Starting

OK,I assembled my computer today and when I push the power button the two front cabinet fans and the power supply fan move and light up for a second and then turn off. Nothing else happens,the system does not even gets to BIOS. Also to note that the cpu heatsink fan and rear chasis fan don't move at all. The start and reset button on motherboard are lit up so that means motherboard is getting power. I've tried removing RAM and inserting it in different slots. So should I assume my processor is defunct? I've checked that I've connected the 24-pin motherboard cable and 8 pin processor cable.
My configuration is- i5-3570k with Cooler Master 212 EVO heatsink
Corsair Vengeance 2x4GB RAM
Asus Maximus V Gene Motherboard
Corsair GS600 PSU

Any of the debug leds are glowing?
Try pressing mem ok if your motherboard has it.

None of the leds are glowing,only the things which I mentioned above. I'm going to take apart and assemble again. I did not use the mounting screws for the mobo,gonna use them this time. Will report back.

Try pressing 'start' button on mobo and see what happens.

Buddy crosscheck golden non insulating screws behind motherboard. I mean it should cover whole motherboard. If any motherboard part is touching cabinet from back then it will short within few seconds. I already faced such type of situations 2-3 times. It is the only workaround.

It was giving the same result.

That was the problem. I figured it out last night and now my PC is up and running. Thanks for the help.

Can you explain what you mean by this? I'm curious..

As far as I understand that if you don't install the standoffs at the proper place and a part of motherboard touches the case or the standoff touches the motherboard where it is not supposed to then the motherboard shorts and the system does not boot up. I also did not know this until yesterday. I searched for my problem on Google and found this thing. Very interesting....

Motherboard touching cabinet = short-circuit = motherboard isn't getting the given 12V = no POST.
