no post Can I be sure PowerColor RX 470 works with old HP Pavilion if I use different PSU?

[GnatDaGnat]

I am in the middle of troubleshooting a PC I built that used to be working, then after using it to troubleshoot another rig it has stopped POSTing upon rebuilding. I wanted to test the graphics card (PowerColor RX 470 4GB) in a different system, and the only one I have access to is this old HP Pavilion tower with a PEGATRON 2AB6 motherboard containing an i5-2400, and a PSU that definitely won't power the GPU. I used the PSU (I know it's functional) that goes with my custom built rig to power the HP instead of the one it came with, stuck my 470 in the PCIe 2.0 x16 slot on the PEGATRON mobo and the system did not POST, same as my build has been doing. I know the display and display cable work.

 

Should the graphics card definitely be compatible here - meaning it's (at least one of) the culprits preventing my own system from POSTing? Or is there a chance it's not a problem and the reason the HP doesn't POST is simple incompatibility?

 

As far as I am aware this shows that the card is dead, but I am looking for confirmation from potentially much more experienced and knowledgeable people here on this forum. If you know of any reason for the RX 470 not to work in the HP given sufficient power, please let me know! Thanks very much in advance.

EDIT: Apparently should specify the HP is HP Pavilion p6780t CTO Desktop PC

Have you tried updating the BIOS of your HP Pavilion, alot of board from the 2000 series wont run a modern GPU without a BIOS update.

This is a p6780t, that's not 2000 series, right? Lol

I can try that anyway though, I downloaded a file from the HP website though it's listed that it's from Dec 2011, I don't know if that is going to be the proper update, do you?

 

Thanks

EDIT: Just saw some Amazon reviewer for a 750Ti saying his p6780t couldn't run the card due to lack of a recent enough BIOS update; this gives me doubts with the RX 470 being even newer than a 750Ti. That being said, it's a comparison between AMD and Nvidia GPU's, could be there's no reason to draw any conclusions about the 470 from that.

2000 Series meaning processor model.

Modern AMD and nvidia cards often require an updated UEFI BIOS to actually get past POST.

 

If your last BIOS update is from 2011 it might not be enough sadly, but doesnt hurt to try.

Ah, of course. Well as far as I can gather there's no way to get such an updated BIOS on this board. Do you have any suggestions? Is there such a thing as custom firmware I can set up and put on there? (Long shot ik...) Thx.

Highly unlikely, while BIOS mods do exist there are uncommon and motherboards and even more so for OEM boards, especially ones that are not gaming systems.  It might be best to skip over troubleshooting the GPU and tackle the rest of the system, if all other components pass than I would assume the GPU.

That makes sense, thanks again for your help
