Sapphire RX 480s not booting up (no display output) on my mining rig

my gpu is unable to start. Fans dont turn on but the sapphire led lights work fine as well as the cpu heatsink fan.

I took an old gpu, plugged it in and it works like a charm, so i thought the 480 was faulty but that is not the problem cos it worked fine on a normal computer (i checked myself).

please help cos iv literally tried every thing i could think off :(

mining specs:

Mobo: MSI 970a-g43

Ram: 4 gigs ddr3

Gpu: sapphire rx480 (3 nos)

PSU: cooler master 700 watts

cpu: amd sempron 145

Ps: this is a mining rig. thats y the specs are a little weird :p

  1. update the BIOS of the motherboard to version A.6:
    https://www.msi.com/Motherboard/support/970A-G43.html#down-bios

    use m-flash integrated in the BIOS and an USB flash drive with the extracted BIOS file on it. Don´t flash in windows!

  2. A rx 480 graphics card is a decent card to play games with.

    As you said it`s a mining rig.

    With a sempron 145 cpu it would choke the RX 480 card when gaming I dare say.
    Good job your not using it to play games on then eh !
