So i bought some pretty good quality RAM and i'm trying to install and test them. Trouble is, i can't seem to get the screws to budge. Not one of the ten on the underside of my machine. It's crazy. I'm turning them anticlockwise, and they're so tight they're stripping my screwdrivers. Far worse, is if this messes up the screws themselves. Any advise will be greatly appreciated!
