I recently bought two 7950's from the MM and I had issues with the first one but the second one arrived and works perfectly no issues at all. When setting them up in crossfire it works smoothly until I boot into a game or test software and I get these glitches? (see pictures below) and I'm just wondering whether there's anything I can do?

Make sure that your crossfire bridge is connected properly, could even try swapping the bridge for another one.

Make sure that you have enough power to both gpu's these cards use a maximum of 220W each.

Make sure they are both at stock no overclocks.

then see how it does :)

Only have one connector unfortunately but I've made sure its securely connected. And running a 1000w superflower psu :) As far as I know they're both running at stock clock.

Running at 925MHz clock and 1250MHz Memory clock. And temps are between 28-32c for both cards.
 
What motherboard and what make and model psu do you have? Have you got the latest bios for your motherboard, especially if it's a Gigabyte board.

Running an Asrock Z68 Extreme4 mobo and updated the BIOS about a week or so ago. And running a 1000W Superflower PSU
 
ok I'd remove the good card, and put back in the one you had issues with on it's own.
Then monitor using gpu-z, It seems the memory/core is either overheating or possibly faulty on that card.

Having the faulty one in all it gives me is an "out of range" error, had that since the card first arrived and still can't fix it :(

The other card works perfectly, had no issues at all (so far) running that solo.

Yeah your problem is the 1st card is corrupting the image when the cf is active.
Sounds like you need to investigate or get a refund on the 1st card.
As you aren't getting a monitor output from it.

I think I'll have to try for a refund, I've tried every option I can to make the first card work but still had issues with it.

Thanks for your suggestions :)
