Yes the screw is there and screwed on hand tight with the metal clip touching the bronze dot on the mother. Any other ideas?

You see the bronze clip at the top of the motherboard is it touching the frame when the motherboard is attached in? If not bend it slightly so it is be careful it's easy broke!
