So I just took all the screws off the back, kept them in order, put my memory in, and then put the cover back on. All screws went in perfectly EXCEPT ONE. It sticks out a bit no matter what I do. I've removed the cover twice and tried it again -- nothing. It's making me nuts, it's going to be something I will feel every single day. And if I keep dinking with it, I know I'll strip the screw.
