Does anyone have any ideas?

Here i have a screenshot: http://i44.tinypic.com/j0k395.png

Hey thanks for the reply, i found that topic when i was searching earlier, it didn't seem to help.
The 11.11 drivers simply made my miners crash on startup.

After swapping out some hardware, the only likely cause to me seems the motherboard.

Anyone any ideas?

Hello

I've been breaking my head over this problem for the last 24 hours and I've tried almost everything in my arsenal.
Therefore i'd like to ask the opinion of this board as i can't think of any other measures.

I have a rig with the following:
- AMD FX8120 cpu
- 3 * AMD 6950 GPU's
- 1 * AMD 6570 GPU
- WD blue HDD
- CM silent power 1000 w PSU
- Gigabyte ga-990fxa-ud5
- Win 7pro OS

The problem is that when i start GUIminer i don't get shares, the cards load up and start under a load.
From the console i can see clear errors saying: verification failed, check hardware!

The following is a piece of the log:

I've tried the cards in another pc where they mine flawlessly.
I've reinstalled software and even the whole pc.
The cards are not overclocked, cooling is adequate.
The cards placed separately in the rig are also unsuccessfully.
The cards work as thy should when benchmarking.

Thanks in advance for all usefull comments!
