Question My Computer keep turning off randomly

[sikorumbe]

Hi Guys,
My computer keep shut down randomly and it really annoys me. I have a pretty decent setup and recently i just bought a new power supply. The shut down happened quite random, sometimes 2 consecutive shutdown within short period of time (10 mins) but sometimes it happened on longer duration (half-day period). On a lucky day, the shutdown never happened.

Here's my specs:
CPU: Intel Core i7 4930K
RAM: 32GB DDR3 Corsair
VGA: GTX 780 Ti Asus
MB: Asus Rampage IV Black Edition
PSU: Seasonic 850 Focus Gold
SSD: Samsung SSD 850 EVO 500GB and 2 other physical Western Digital HDD

I'm using NZXT for my CPUter cooling system and here's my average temperature based on the monitoring software:

Please help this poor soul in finding what's wrong with my PC.

Thank you guys.

Power down, unplug, open the case.

Double check that all cables, cards, RAM, jumpers, etc. are all fully and firmly in place.

Visually inspect with a bright flashlight and by feel. Connectors and cards should not be tilted or at an angle.

Also, if the system is full of dust and debris - clean first.

Hi
Thanxs for the reply.
But the problem still persist.

I took a photo of my CPU, i think it's pretty clean and all the cable + memory seems tightly placed.
