I've just bought a Sapphire Radeon HD 7850 2GB to replace my GT 730 with. I bought it from a seller with perfect feedback on ebay so I thought it would be fine.

Received the card, it was well packaged and in an anti-static bag - so far so good. Installed the card attached power cable, etc and powered up PC - no signal to PC - message is 'DVI No signal' - you get the idea. Card is defniately getting power as the fans were spinning. So I've done a bit of research and have found that this seems quite a common problem. I've tried the recommendations such as making sure MB boots to legacy BIOS, upgrading BIOS, trying other PCIe slots - I even tried another MB that I have spare and no change. This interesting thing ti note is that when I go into the BIOS I can check the hardware that's installed - it has the PCIe slot that the card is in as 'empty'.

My spec is:
MSI Z97 PC Mate
Aerocool 550W Modular
i7 4770
12GB RAM

The other MB was an ASUS H81M-C.

So I came to the conclusion that the card is faulty and have put in a claim - needless to say that the seller is unhappy and claims that I've damaged it as it was working when it left him.

I'm really looking to see if:
1 there might be a fix that I've not tried
2 you guys think that I'm right and the card is basically goosed.

Thank you so, so much for taking the time to read this and help me.

Test the card in another system with a good power supply that can run the card, if it does not work there, bad card.

Another issue is that you have a poor quality power supply that may not work with a 7850. Make sure the other test system has a good quality PSU. You may also need to test a better power supply before calling the card bad. Without trying with a good power supply you can't call the card bad.
