Those lines that are under the screw are traces. They have copper in them for the PCB circuitry. There is a chance that you damaged them, and next to the bottom right corner of the screw it looks like we can see copper. It's very possible this board is messed up. It looks like there is something between the backplate and the motherboard which caused the plate to not be flush to the motherboard.
It's the screw between the backplate and the motherboard... it was linked to the backplate using a plastic cover and popped out when I forced it too much.
The silver component beneath the frame seems to be the CPU socket holder for an Intel processor. This is how it appears in my situation...
James, thank you for your kind words! I'm really new to this project. Do you see the traces as being cut? = yellow arrow. Are those two red arrows similar to what would happen if the parallel traces touched? What would occur if I power it on and they become cut or touching? Should I use regular black 3M electrical tape? Do I need to clean the area before applying it? If yes, what should I use for cleaning? Thank you again! Alan
