Ram which is the easiest thing to install has always been a fucking pain for me, and been the hardest thing to remove put back.... end up needing to push it in hard, once broke the white plasticky tabs on the board, but with a big hard wham in, it stayed and worked... Usually I end up having to use quite a bit of force, unfortunately it takes me a good 30 mins of fiddling with my new stuff which cost money getting sweaty hands before resorting to the last resort...
