Very strange issue. If I plug my 23inch Mac Cinema Display with DVI plug into the Graphics Card, the computer will not boot. Does not even get to the point where I can enter BIOS.

However when I plug in a VGA monitor it boots without problem. Once booted and up and running, I can unplug the VGA monitor and plug in the DVI monitor and it runs fine. However if I then restart the computer it will only reboot if I pull out the DVI and revert to the VGA monitor. Any suggestions?

I have tried 3 different graphics cards, all of which I know work in other machines. Same result for all. Could it be an EDID problem and if so how can I resolve that?

Sytem comprises:
Intel i7 3820 s2011
MSI X79A GD65 8D
4 X 8GB CORSAIR VENGEANCE CMZ32GX3M4A1600C9
NVIDIA GeForce 7600 GS
BIOS V1.4
1TB SATA 2 DRIVES
CORSAIR GS600 PSU

All and any thoughts appreciated!

Thanks, but i have had a good poke around in the BIOS and can find nowhere to configure anything to do with graphics.
