sometimes I have found that the little tab on the card does not go into the slot on the bottom of the case, I have had to bend it out a bit with pliers so when it is installed it will go into this slot. And then you can screw it into place. Kinda hard to explain but look at your case where the pci slots are and you will see a slot on each pci. Hope this helps.....sm
