I'd try changing Primary Graphics from IGFX to PCI-E and disabling Gfx Low Power Mode. Not familiar with the other settings unfortunately but hopefully someone else will chime in. If Windows can't see the card, that implies that the card isn't properly recognized by the board at all so power might indeed be the issue. If so, a server PSU + breakout board and cables is around 50$ and might be the cheapest option besides some Molex->PCI-E cables (those 6-pin connectors on the board are PCI-E, right?).
should work fine to embed pics but might be restricted for new users, not sure.
