    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:
    1. 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?
    2. 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.
    3. Could the motherboard be completely damaged?

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

    1. You may need to remove the links that show where you bought your PC hardware .

    2. Read the T&Cs .

    These are links from the manufacturers, not the suppliers I purchased them from.
