Have you confirmed that the Radeon card works in another PC? Validated that it isn't faulty?
Does the HD7570 require external power?
Some HP motherboards can be very finicky in regards to discreet GPUs be detected.
Have you checked for any more recent BIOS versions? Could just need and update to detect the card.
Barring all of that you might try another known good PSU.

Make sure the power supply is enough. The card isn't power-hungry but, assuming you mean 5800 SFF, these came with a 240W PSU. It's marginal and possibly not enough.
I can't find any information about a TFF 5800, only SFF, but if it exists the PSU might be even less watts.

Edit: on second thought there is another even more probable cause: these computers are only capable of delivering just a few watts through the PCI-E slot, usually something around 20-30W. If the card doesn't have an external power connector this might well be your problem since it needs around 60W. Have a look at the computer's manual, they do mention the max watts a card can draw.

The problem is I don't have any other low profile gpu to test it with the rp5800 at the moment. I'll try to hook up the hd7570 to my main pc later.

Oh, and this fellow got some similar Radeon hd card to work with the rp5800 semmingly with no problem https://youtu.be/Wl0Ahf3yDok

This has a TPM, you need to set up the security section and other items to allow GPU in the security white list sections.

RP5800 was a POS system for cashier use.

Thanks, but how do I do that?? 😳 I don't think there's such an option in the BIOS, unless it's in some hidden advanced settings menu that I don't know how to access.

Explore rest of the bios settings. Most of it in security and last tab menu has some as well. I have many HP computers but not the POS machine in my herd.

Cheers,

The "similar" card is a 6350 which is a 19W card, if i'm not mistaken yours is 60W. So not that similar.

Did you check the manual? I did, it says that it supports max 25W from the pci-e slot. Now i know that practically cards that draw a lot more than 25 often work (or "work until the board gives up"), but a 60w card is very likely not to. Just keep this in mind as a possibilty.

Well yeah, but shouldn't it at least get detected in WinXP?

All I got is this:

(cont.)

try to disable the slot security for the pci-e 16x (or maybe all slots), makes sense if it has TPM.

That doesn't work either 😒

https://www.techpowerup.com/gpu-specs/radeon-hd-7570.c393, the video card has a TDP of 60w, maybe the motherboard can't supply that power trough the pci-e slot. Try with a less 'power hungry' video card.

PCI-e slot 12V pins is designed to be driven up to 75W. Yeah there could be a power limit somewhere, try something different.

Cheers,

Aye, thanks for your suggestions guys. I think I still have a pci s3 virge somewhere (my very first gpu from my very first PC!), I'll stick it in the RP5800 and see if that works (there's a regular pci slot in there too). If not, guess I'll ditch the RP5800 and build a different system around the HD 7570. Although I do find the SFF HP kinda awesome, with all the folding bays and the built in speaker and what not. Oh well...

UPDATE: The virge works, so either the Radeon is busted, or it's not getting enough juice as some of you suggested.

UPDATE 2: I hooked up the Radeon to another PC, this one had a 500w PSU - no go.

Good news.

See if you can borrow another low end PCIe video card? I stick full height video card in those SFF case and this works for testing.

Cheers,

OK, final update I guess: I bought a GeForce GT 530, stuck it in the PR5800 and so far it works without a hitch. I tried to return the HD7570, but the seller is a bell end 😒

Still, even though it ended up costing me like 30% more than initially planned due to the whole GPU debacle, I'm pretty excited about the build, will use it to play NFSU and NFSU2 in the near future 😁
