Ok, I've now been able to determine (via fiddling in the BIOS) that the IGD was disabled before, and hence not being seen in Windows. The problem therefore is that I can't seem to have the integrated graphics AND my PCIE card enabled at the same time? I was really after this for the extra DVI output so I'm a little disappointed. Any suggestions? Selecting anything other than pure "IGD" for the primary boot device seems to prevent the integrated graphics from being seen in Windows, even if I choose PEG/IGD as the option.
Any help hugely appreciated.
