Hello,

Just built another Bitcoin mining rig and got one problem, one our of the three GPU's is not detected in the system.

I have connected 2 6970's and 1 7950, it's the 7950 that's not detected. Everything else works fine, is there maybe some fix for this?

Sorry for such a late reply.

I did try what ingtar said but now the problem is this, there is no video output of the card connected ( only the 7950 is connected through a 1x to 16x riser ).
I can connect to the computer through TeamViewer but the screen is all blurry and you can't really make any sense of it.

I've had this issue before, and I know that I have to click on an pop-up where I'm supposed to choose if I want to install the new drivers or not, and after clicking OK i need to restart the computer, but now as I don't get any video output and can't see anything in TeamViewer I'm simply unable to click that button and then send the request to restart the computer.

Any suggestions on how to solve this? Previously when having this issue the video always came up when connecting a screen to the video card, this did not happen this time.

Thanks in advance!
