Try this. Go to a PC repair store and ask them to check your 580 in one of their PCs to see if it's defective. Usually they will do something simple like this for free because it only takes a minute.
Everyone around me is closed since it’s sunday but will do

The only other slot you have is pcie 3 is it full size if so then that's the correct slot?
There’s cables from the mother board blocking it from going all the way in , and me not being a technician I’m unaware what the cables are for

OK a pc shop might be your best bet, could you take a picture with the side panel off? Out of interest what country do you live in?

The top pci is the one my old GPU was one and the one i have been testing with this one , the one underneath the “pci express 3.0” the blue cables and the ones all the way at the bottom right are blocking the card from going in and I’m from the UK

There's some misinformation here.

First, there's no such thing as a UEFI-only graphics card. If it's UEFI compatible, it's because it has a UEFI GOP image added to the VBIOS. Which is essentially tacked on to the end of the Legacy image. Making it what's known as a Hybrid VBIOS(as in both Legacy and UEFI, 2-in-1). Which means you can use a motherboard's UEFI GOP features(fast boot, secure boot, etc.) with the card installed as the primary GPU.

Second, regarding that reddit post, that's just as much about GPT vs. MBR, as it is UEFI vs. Legacy. What I'm getting at there is, as far as using UEFI GOP features, you need to have your OS on a GPT partitioned disk. Since UEFI only supports GPT. But you don't need to use any UEFI GOP features(as in have them enabled) with a GPT partitioned disk. And you don't need a graphics card the is UEFI compatible, unless you want to use any UEFI GOP features. Meaning, you can run a Legacy-only card on a UEFI system. You just need to disable UEFI GOP features. And not even all of them really. Just secure boot. Other UEFI GOP features will not work correctly(like causing a black screen during boot, instead of seeing the Windows boot screen, with fast boot enabled). But the only thing keeping a computer from booting with a Legacy-only card will be secure boot. And UEFI or Legacy mode has nothing to do with Windows recognizing/detecting the card once booted. That can only be caused by something else entirely(what that is, is the question).

Bottom line: This has nothing to do with a UEFI-only graphics card. Since there is no such thing. And there's no real need to use Legacy mode to boot with a Legacy-only graphics card. You just can't use UEFI mode, with secure boot enabled, with a Legacy-only graphics card. And there's no reason whatsoever to use Legacy mode to boot with/use a UEFI compatible graphics card(unless you need to use Legacy mode because the OS is on an MBR partitioned disk).

It's a sapphire it requires uefi, go Google it, something specific to sapphire rx series cards, I've had the same issue myself as have countless others and the issue has been confirmed by sapphire. Edited as it didn't make sense typed up on my mobile lol

First: put the original GPU back into the PC. Then, use DDU to completely remove the old driver from your PC.

Then: shut it down and swap the cards to the new Sapphire GPU.
Restart and see if you get any display. (do not use the onboard graphics at all)
Install the new drivers if you get a picture with the new GPU.

The slots are definitely in.?When i change init to peg it automatically changes it back to auto after saving and exit , the only other slot i have is a pci express 3.0 slot and no other machine

I am concerned about the wording here.... to get power, this card needs two sources ... the PCI slot + the PCIE 8 and 6 pin cable. You have said multiple times it's in the slot but not mentioned the cable(s). I hope this is a semantic thing but you card

This pic is from TPUs review of the Sapphire Nitro Plus 580 Limited Edition



This card gets its power from:

PCI Slot = 75 watts
6 pin cable = 75 watts
9 pin cable - 150 watts

That card drew 240 watts in TPUs testing

No doubt there's 580s out there with just an 8 pin and I hope it's just semantics that when you say "the slots are definitely in" you mean the PCI Slot is in AND the PCI-E plugs on the power cables are in those pictured socket(s)

it was shown in one of his pics it had both cables connected and it will run off just 6 pin, guess 8 pin is for oc etc, I know, I have the same card 4GB version. But yes info is sketchy unfortunately.

don't know if you fixed it or not, but turn off the onboard gpu in bios, and wait for it to boot all the way to windows load screen, it might because the gpu is working as a secondary gpu as in a crossfire config, it wont show bios screen but will show windows once it has booted fully to windows.
I have crossfire and using hdmi from one card will not show bios.
even if there different types of gpu, mgpu (2 gpu's of any type) will make it a secondary card.
