So after taking out my CMOS battery and resetting my pc, it does work now. However I have no video output, i hear a beep, all fans start spinning, Leds light up and then... no screen at all. Used it with a DVI adapter and nothing either. I have a VGA cable on my monitor, and a GTX460 GPU.
And yes i put the card in the slot correctly, also i connected the 6/pin PC-I connectors.
