GPU hardware problem

SO i have a GPU that sort of works.

Problem

I have 2 cards and one works perfectly fine in any pci-e slot

Next card this does not work on is own. Card fires up like its meant to by the sounds of it powers up fan spins gets warm etc and would of thought would boot but no output signal coming from card.

Next I put card in with no problems and the 2nd card that's got problems. System boots up, and detects the 2nd card in bios. How can i get these cards working together or working separate so i can use in other machine

Need dummy plugs?

Nope cos am not that far yet read what i actually said.

Card will not give any output signal if on its own. So am trying to figure out the problem first, as that is the fault and it does not work paired up.

It shows in bios as been their but not working. And card does not work on its own. So I need to find out why its not working or something I can do to fix and get working.

I want to help you but your lack of punctuation makes it impossible to understand what you're saying.

Please revise your post and put in periods after each complete thought.

Insert commas where you would pause if you were speaking.

SOunds a lot like a 5870 I have. System will not boot or post with problem 5870 in primary PCI-E slot or by itself. I can install it along side another card though. It does not having working display output. Fan is stuck at 100%. It is however detected and driver installs fine. It also mines fine as well, but voltage is possibly locked to something close to stock volts (920MHz at 1v = unheard of? Probably locked to something higher).

If your card still mines along another card, don't do anything and keep mining. If it doesn't...

Run the card with another card that works. Use gpu-z to read out the broken gpu. If it's still recognized, you can try to flash a new bios onto that card with lower core values and maybe lower ram and see if it boots up again. An incorrectly set bios can be a reason for non-booting card.

If you want to flash the card, you will first need to read out the bios with gpu-z, save it and load the bios info with a program to change its values (forgot the name now), then save the new bios and flash it onto the gpu with Ati Winflash. I would use the original bios of the gpu, or worst case find another bios of the same card on the internet, download it and flash your gpu. All of this may help, ruin your card, or it may not help with reviving that gpu. If you have nothing to lose and know how it's done, it's worth a try.

Apart from this, the gpu is broken and can't be repaired easily. You could try to remove all plastic and put it in an oven for 30 minutes. Final straw. Read about 'baking gpus' in this case.

Make sure no pins or capacitors are broken or burned at the back of the card, even removing a gpu can cause stressed capacitors to fall off.

If none of all this works sell the gpu as spare-parts/defect on ebay.

Thank you for the advise here I will keep trying and see where I can get with it. So far I had no joy. I have also had the card re flowed in a shop however made no difference still doing what it was,

Regarding post to bios, Have not tried this yet once I get card back from hardware shop ill have a look at doing this but having the card fully tested as might of missed something on it.

Other than that can only wait and see when card is returned later today. Will post updates when I get card back and more testing done.

Just a thought, I had something simalar, Turned out to be a bad Video output port. With the bad card in, Does it still boot up in the background, Noises and normal "bleeps" and lights? Try the different hdmi/dvi/component ports, Avoiding adaptors where possible.

Thank you for all the hard help and support here. Have had no join what so ever with the card. I have also come to an agreement with the person who sold me it and is happy for me to be refunded.

It would of been nice to get this card in full working order however no output of signal what so ever on it.
