Motherboard not accepting my Asus radeon 580 8gb

Hey, this is my new build and I've run into a problem. My motherboard and CPU go into boot but because it's not accepting my gpu so can't do anything on it. I think it is to do with my gpu as there is a small red light (I think they're the indicators) which doesn't go off, indicating a problem with gpu (OR as the mobo says, vga). I know it isn't the gpu as it is brand new and only arrived today

I dont know what to do from here and I'm getting really frustrated so any help will be amazing.

Specs:
Ryzen 5 2600
Gigabyte AB350-Gaming 3
16gb (2x 8) ddr4 ram
Asus radeon rx 580 OC version
500W power supply

    Model and brand? because maybe the PSU can't handle the rx580, or the MB (pcie slot) has problem.

    Do you try the gpu in the 2nd pcie slot? or try other GPU?
  2. you need a bios update most likely to run Ryzen 2600 on a b350 chipset board. it does not natively support that CPU without a BIOS update. that is probably why you aren't getting a display. also make sure that your monitor is plugged into the GPU and not the MB
  3. is everything lighting up and fans spinning?

    The gpu is Asus radeon dual series radeon rx 580 8gb OC edition
    The mobo is a Gigabyte gaming AB350-Gaming 3

    I've tried the gpu in both pci slots and neither have worked.
  5. What PSU did you have? Model ? sorry, not the Rx580.

    How do I go about updating the bios if i cant get a display? This may be a stupid question but i don't know
  7. BIOS is the first thing which stands out to me as well. I don't know if AMD still offer the boot kit for these situations but you could check: https://www.amd.com/en/support/kb/faq/pa-100

    For a BIOS update you need a compatible CPU. The motherboard manual should have some instructions, if not check the other tabs for a downloadable manual: https://www.gigabyte.com/us/Motherboard/GA-AB350-Gaming-3-rev-1x#support-dl-bios
