Hi all

WHAT IVE DONE / TRIED

Installed everything from scratch.

I have read and done all steps in :
http://www.tomshardware.com/forum/261145-31-perform-ste...

PSU works on another system
Can't test the RAM, but that's irrelevant as nothing happens even when it's taken out of the system.
I do not have access to a similar board with a LGA 1155 socket, so I can't individually test either of them.
I connected the Power Switch from another system to see if the switch on my case was faulty, but it also didn't work.

PROBLEM / INDICATIONS
Standby LED on MOBO lights up
Other diagnostics LED's on board don't light up
Besides a slight twitch (not even a 1/4 turn) in the video card fan when pressing the power button, nothing happens. There is no sound, no movement, no noise, nada.

Note that I started with everything inside (including RAM, video card, SSD). Have been working one step back everytime removing a single item at a time until I was left with nothing but the MOBO, CPU and PSU.


HARDWARE:
Asus Sabertooth Z77
3570k i5
Corsair TX650 (tested and working)
Corsair Vengeance

As much as I hate to say it, it is time to get in contact with Asus to start the RMA process - pretty sure it's a faulty mobo you got there.

The one thing you haven't said that you have done is to build the computer outside the case, also try resetting the CMOS memory.
