Motherboard not detecting graphics card

I was just wondering if anyone may be able to shed some light on why this is happening (I'm suspecting its the graphics card at fault).

First off here is my system specs:

Everything is running nicely without any problems, but I wanted to add a second graphics card so I found a second hand one of the card I already had installed meaning there shouldn't be any problems SLIing them.

I got the card today and it all looks fine, I placed it into the correct PCI-e slot (the board states they should be placed into the 1st slot and 4th slot (the third large slot) ) I attached the SLI bridge.

I booted the system but it never detected the card, so I went into the Bios and it hadn't found the card. I took the card out and placed it back into the slot, again it wasn't found.

I took out my working card and placed the new card into that first slot, the card had power with the green lights on the side next to the 8 pin and 6 pin connectors and the fans would start.

It booted into windows as I had my speakers on and heard the windows start up sound, but there was no picture.

Placing my working card back in and the system boots fine and displays a picture.

Any ideas as to why this may be? otherwise I'm going to have to try and send the card back to the guy I got it from on eBay (hoping he will play ball and give me a refund and not having to get eBay involved)

Cheers in advance for any help.
 
Add in your system specs, might help.

If you've got onboard graphics then can you get to bios with just the new card in and see if it's recognised?
 
Damn sorry here are my system specs.

It doesn't have on board graphics

have you recently updated the bios on the mobo? I have an asus mobo that I have to keep below a certain bios revision or the same thing happens, not sure why.
 
I updated it to version 7 when I got the motherboard before I had installed my graphics card. It didn't affect that card, so by that logic this new card should work as well :S
 
It does sound like a faulty card considering that it is identical to your existing one. I think this rules out it being an issue with any of your existing hardware. Double check that the monitor cable is connected firmly. Are you able to test it with a different cable? also if possible can you test the other outputs? hdmi? vga? and do you get anything out from that?
 
Does sound more like the card if they are identical.
Mine does strange things depending on the bios switch of the video card. When I had 2 6950's they unlocked fine but when on the 6970 bios with a later revision mobo bios they would not display. switch them back to stock bios they were fine, swich back to earlier mobo bios and they would work over clocked on 6970 setting. Now with a 290x no matter which bios is selected they won't work with any newer bios.
 
I tried booting with different cables DVI and HDMI but the same problem. I have now sent the card back to the seller and a waiting refund, as it seems to be a faulty card (maybe from him taking it out of his machine).

Thanks for the help.
 
It could have been a VBIOS version on the GPU your motherboard didn't like on the graphics card, only way you would have found out is if you could boot the card into windows to find the VBIOS version it was running compared to the working card. Sometimes you have to take the card to another PC and try it and if it boots fine update the VBIOS to the same one that is known to work for you on the main system.

But it could have been just a faulty card too, but who knows now .. to late to check.
