My son received a Club HD 7950 has a prize but unfortunately it doesn't seem to be working. Everything powers up including fans on 7950 but monitor just says no signal, tried DVI and HDMI.

Spec - Asrock H61m-itx, i5 2500k and PSU is silverstone 450w that's included with SG05. I have a 7970 on the same PSU in my rig and have no problems

I'm just wondering if there are any comparability problems with the motherboard or if anyone has any ideas?
 
Does the PC boot without a display or doesn't it boot?
I had a problem when I put 2 7950 on my X79 board that it didn't boot and actually came up with an error code on the board display. Turns out I had to change the PCI EROM from "EFI" to "Legacy".

Would it be possible for you to test the card in your PC?
 
Not tried a different PSU but same PSU was powering a GTX 560TI without issue, don't think the bios as ever been updated in the two years he's had it. We have 3 x PC's built using the SG05 - 450w case + PSU in our house and while they're great cases you literally have to strip everything out to fit the card in first, takes a while :(

The PC boots and accesses the hard drive like normal but screen is blank / black and eventually the monitor says no signal and turns off.

Also tried plugging monitor in to motherboard and get same result while 7950 is in, but when I take 7950 out I get a picture through motherboard to monitor connection.

Could very well be the Bios, I have had two Motherbords that had the same issue and needed a BIOS update for it to work.
 
Turns out all that was needed was a Bios update and it's working fine.

Thanks shankly used your link :)
 
It was a motherboard bios update, I assume the board was released before the card, so it needed an update to play ball.

This..
I have had two z68 boards the had out-dated Bios for the 7000 series GPU
I not 100% sure if this happens with Nvidia cards also though.

If you look at your Motherboard downlods page under BIOS 9/10 you see an update with something like GPU compatibility in the changelog.
