dude, expansion cards NEED THOSE SCREWS TO WORK!
You can't just support a card entirely on the pci-x x16 socket! get some screws for the case and that will fix your problem, it needs all of those pins, it can't just run on a whole half of a socket.
imagine if someone got a scalpel and cut away half of the nerves that connect your spinal cord to your brain  nobody would work that well like that either, the pci-e x16 socket is like a spinal cord to the graphics card.
the reason why its doing it is because the pci socket has 2 rows of pins and when the gfx card is pulling down on the PCB board of the gfx card it only allows contact to one side of these pins which are located inside of the pci socket, most likely the bottom row of pins aren't getting sufficient contact inorder for it to work properly.
when you have the screws mounting the graphcs card higher up to the chassis, it makes a perfect contact surface with BOTH rows of pins that are located inside of the pci socket, in essence taking the huge strain off of the pci socket.
failure to do this in a situation like for example where your computer is falling off of the table WILL result in the graphics card ripping the entire pci-e socket off of the motherboard once it lands on the floor, as the entire weight of the graphics card is exerted upon the pci-e slot on the motherboard, rendering it useless without replacing the motherboard.

Anyone skilled in computer boot up process?
