Good Evening,

The issue I am getting is I am unable to get a display from my GPU. Had my PC in at a specialist after spending a couple of weeks trying to get it working but it ended up not being worthwhile. He suggested buying a "gaming" motherboard or a new GPU as a solution so I went with a new motherboard which didn't help at all.

My PC is an AMD build with fairly new Ryzen hardware rocking an RX 570 (Brand new part). I know the GPU is working as the specialist had it inside an Intel build while troubleshooting.

Upon boot with the GPU inserted correctly I get no display at all. If I connect a HDMI to the motherboard I can go into the BIOS and find it doesn't pick up my GPU when inserted. The GPU seems to work fine from the outside (Lights flash fans spin)

What I have done:

- Reset CMOS via the battery
- Reseated each individual stick of ram
- Used DDU to uninstall old Ryzen drivers
- Completely reset windows
- Used the second PCIE port
- Disabled on-board graphics (resulted in no display)
- Purchased a new motherboard
- Updated BIOS
- Possibly other things I can't think of

As a side note the GPU worked the first night I installed it. When I turned the PC on the next morning it didn't work ( I never changed anything). I was able to get it working by force disabling my onboard graphics on my old motherboard but again it didn't boot upon next boot.

My PC components are:
Ryzen 2400g
2x4GB 2400mHz Ram
Asus B450-F ROG Strix
Asus ROG Strix RX 570 4GB
Aerocool RAVE 800W PSU (PSU apparently works with NVIDIA GPU)

A big thanks to anyone who can help in advance

That psu looks suspect to me. Check with a higher quality model (seasonic corsair, evga) at your pc specialists place. It should have at least 450watts on single rail.

I'm not too well educated on PSU's, how under powered do you think the unit is? Online says the unit has a 12v rail?

Thanks for the info, but can I just ask one more question? I haven't picked out a PSU before as that one came in a case, so how much wattage do you think I'll need? I did a quick check on PC part picker and it says 250W but I don't really trust that figure.
