Custom built computer not booting up

[AdityaDewani]

So my pc was working completely fine. But from some time, it turned itself off automatically. And most of the times, i am not even able to boot it up. When i press the power button, it makes a click noise, one of the CPU cooling fans rotate, and its off again. No display, no lights, nothing! I even changed my thermal paste but no luck. My configuration is -

1) Asus maximus 6 extreme MoBo
2) Nvidia gtx 780
3) 2*8Gb Gskill ripjawsX 1600Mhz
4) Swiftech H220 Liquid Cpu cooler
5) Seasonic x850 gold power supply (850 watts)

If anyone knows how to solve this issue or know what part is causing it, Please tell me. Thank you!

So i checked all of it, my pc started booting up normally, and then i left it on for an hour or so and thrn it switched off automatically.

What about the power plans? Check whether it was set to turn off after 1 hour?

No it wasnt. And now ive hit it 5-6 times from the top just to get to the bios. And as i get to the bios, it turns off. And what if i hear liquid flowing through the pipes of the cpu cooler? And what if the cpu contact plate of the cooler is blackened? Is the cooler a problem?

What CPU and what GHz it is now at?

Its Intel Core i7 4770K and its at 3.5 GHz. But i saw that my Copper plate of the cpu cooler was burned when i was replacing the thermal paste. Is that the problem?

Might be. Check the temperature of the CPU right before the system goes off..!!
Also, you might do one thing, check with the stock cooler whether the system shuts down or not.

Plug out and plug in all the power cables perfectly. Do this for RAM sticks too.

Okay. Thank You!

Install the two sticks in #1 and #3 OR #2 and #4 slots.

Sort of sounds like overheating or a PSU that may be going bad, what are temps on the GPU, might run core temp when on and monitor CPU temps, are all standoffs securely attached, possibility of a short...

The sticks are installed in 2 and 4 slots and i've been using my pc for like 1 and a half days and it turns off 9/10 times. The CPU reaches about 41 degrees and it reached 49 when i was paying BF4 on Ultra settings.
