    My homebuild computer was running fine until Saturday evening when I shut down the computer and went to bed. When I woke up the next morning, the keyboard, mouse, fans, and internal lights were all on (even though I had shut the computer down all the way) and the computer would no longer turn on.

    Parts list:
    ASUS ROG Crosshair V Formula Z
    AMD FX-4350
    PNY GTX 970
    16 GB RAM
    128 GB SSD
    3 TB HDD

    Whenever it was started up, the motherboard LED display shows an error code 99 which is a "Super IO Initialization." I removed the graphics card to try to see if it was the problem and it did not fix it.

    Most recently, I bought the following:
    ASUS 970 ProGaming/Aura
    New Power Supply

    to see if that would fix the problem, unfortunately, it still doesn't post and it still doesn't have anything show up on screen. Anyways, I did get it to POST once, but it gave me a "fan error" since I missed one of the wires.

    Any help or direction would be appreciated, thank you!

    Hey Astieman! I am sorry to hear that your computer does not post.

    Considering that your USB ports appear to be outputting power, I think the motherboard is fine.

    Did your start experiencing these issues after you installed the new hardware, or is it unrelated?
