Re: Need Serious Help
It's possible that the stand off came loose instead of the mounting screw. you can remove all the other screws and see if the board comes out, from the bottom side you should see the stand off.
The screw is stripped. you can gently try pulling up on the board while turning the screw loose and see of the threads catch, possibly stick a wedge between the board and the screw and try turning the screw while wedging up. use something out of plastic like your drivers license or a credit card. Using something metallic will scratch and damage the board, especially if you slip while attempting to use upward pressure while turning the screw
