Computer in infinite boot loop

[rivena]

Hey everyone! This is my first post here so please be gentle

My computer is currently stuck in an infinite bootloop. I have tried removing every possible component, but it still isn't working. It powers up, seems to work fine for 2-4 seconds (Monitor says "No signal" when connected to motherboard during boot) but after this 2-4 seconds, the computer will shut down and reset itself. Every light shuts down from the motherboard.

So my hardware is this:
CPU Intel i7 3770k
Motherboard ASRock Z77 Extreme4
GPU Nvidia Geforce GTX 660 Ti

Any suggestions how to proceed? I have no idea what could be the problem

Typically when a system wont post it is because of a RAM issue. How many sticks of RAM do you have? One may have failed. I would try each stick by themselves in each DIMM and see if it will boot.
