Black screen after installing old GPU again.
I have installed a GTX 680 (pc) in my mac pro 3.1
I then installed a PCIe ssd into the 2nd slot.
I then put the old radeon 2600 back into slot 3.
It was alll working great. I could swap via both DVI ports on both cards and got a picture. In order to test the GTx 680 I then removed the old radeon GPU and it still worked fine. Was working on installing win 7.
But in order to install win 7 via bootcamp I put the radeon card back in so I could choose a partition to boot from if need be.
Now I don't get a picture from either. Initially I plugged the DVI into the back of the radeon and all i got was a grey screen with a flashing folder and a question mark inside it.
I the changed the DVI lead to go into the GTX 680 to see if that helped but it was just a blavk screen.
Any ideas? Pretty sure it was working fine yesterday but today it is behaving bad :o(
