I am able to run the computer fine when it's not installed through my mobo, but when i install my graphics my monitor displays nothing. I've plugged my hdmi into both my motherboard and graphics card so I know thats not an issue. I have a 650 watt supply so its not lack of power. The card does light up when I install it, and the fans spin up but then slow down and stop I think. Ive plugged the graphics into both slots on my motherboard and yes my motherboard has both the 24 power in and the other 8 slot i think on the top left of the board.
