I have recently purchased an ASUS GT640 graphics card for my CM6730.
The card works well, however the pc will not boot unless the cable is plugged into integrated graphics on boot.
It can then be changed over to the card, but I have to do this every time.

I have tried to change primary display to PCIe but there is no display on anything when it is configured that way.

Should I update my BIOS?
