Hi in this report, I have encountered a number of issues regarding my PC build.
As of now, only 1/6 CPU fan is working, I have no monitor output, RGB lights are working on the Graphics cards. Could the motherboard be dead?

Here is my PC Build:
CPU: Ryzen 1800x @3.8Ghz 8 Cores, 16 Threads
CPU Cooler: Arctic Freezer Cooler 360 All-In-One
GPU1: GTX 1080Ti Strix 11GB (SLI)
GPU2: GTX 1080Ti Strix 11GB (SLI)
Sli Bridge: ASROCK SLI Bridge 60mm
Motherboard: ASRock X370 Taichi
RAM: Corsair Vengeance LPX 3000Mhz 32GB RAM (2x16GB)
Monitor: Acer Z35P 35'' 3440x1440 100Hz
Case: Corsair 750D Airflow Edition
PSU: Corsair HX1000i
Extension Lead: 14-Way
Also, Links are at the bottom to understand more of the components and equipment.

27/12/2017-03/01/2018: PC functioning as expected, when cousin was playing Assassins Creed Origins comfortably. After the transportation of the PC to a new location, the PC does not seem to be functioning as expected.

I decided to unload all the boxes setting up my device for use again.
Test 1: First boot-up, windows was running but no CPU fan were functioning.

Test 2: On 04/01/2018, I had access to the motherboard through the monitor, the CPU fan was not functioning at all.

As of Today (05/01/2018 11:00AM), the monitor is not displaying anything, potentially due to the graphics card?
The CPU Cooler is only running one fan, all other five are not functioning.
There is no output to the monitor, however, there was output yesterday. (04/01)
The RGB lights are working on both graphics cards.
All other Case fans are working.
All wires are connected to their allocated component.

Here are some questions:
Is it possible that the 1000w Power supply sharing the power with four other devices through the Extension cable cause a power surge? and the components are damaged through this?
Is it possible that the components were damaged through transmit, I did have the PC case (all components inside) on the back seat, the car did go over a number of bumps and potholes in the road.
Could the motherboard be completely damaged?

CPU Cooler:
GPU1 & 2:
SLI Bridge:
Extension Lead:

Thank you for reading this post, hopefully I can get this PC working again!

I would say, re-seat your components, such as RAM and graphics cards. And I don't like the idea of using extensions from the power supply. Try to use the system with just one graphics card also. Car rides have been known to jar the connections made by the components.

I would like to understand also what you mean by extension cables on the power supply though...
