DZ68ZV not recognizing Radeon HD7950

[Bde_W1]

hey all,

last week Ive bought some parts (dz68zv board and i5 3570) to upgrade my PC, however, now I am facing some problems.

my setup:

corsair CX600 PSU

i5 3570

DZ68ZV

Club 3d Radeon 7950 royalqueen

when I try to start my PC it first will show me the Intel screen (where I am able to choose for the bios mode etc)

after this (when my motherboard shows 00 = hand-off to OS) I get a black screen and a "0_" in the right lower corner of my screen

I also tried starting my PC using a "weaker older" graphics card, the Radeon 5450.

with this card I was able to install windows and run the updates etc on the PC, as well as the amd drivers.

when swapping the graphics cards (since I really want to use my gaming one) the post boot screen shows the "0_" again

what I've tried:

- different pci x16 slots, 1 shows the bios that it's a x8 card, the other will recognize it as a x16 (it also recognizes it's an AMD card)

- different bios settings on the graphics card (both original and club3d boost)

- the bios of the dz68zv is up to date

- installing drivers for the graphics card

- the intel screen shows a 5A in the corner when the gaming card is in the pci slot

extra:

I am sure that both the graphics card and the PSU work, I took them from my older Q6600 setup where they always have been functioning great.

can someone help me out?

after having tried all kinds of tricks, I just booted the pc with both cards, installed drivers for the 7950.

it still gives the "0/" screen at first, but as soon as windows starts loading, it works perfectly fine with only the 7950 connected
