The smaller one doesn't plug into anything and the L shaped one is a lock to keep the card from coming out. If your PCI slot doesnt have that, I would assume it isn't compatible. Do you know if the slot is 2.0/3.0 and if it is 16x?
It is a pcie 16x slot, and at the end of it is a thing that goes straight and then in a 40 degree angle
it is only some kind of thing to protect the pcie gold contact, that 2 part sit next to the pcie slot itself, and that thing can support the graphics card weight so the graphics card doesnt broke or bend because of it weight that heavy
