Alright, so I always understood ram installation on macs to be fairly simple and straightforward. I read up on the instructions, watched the youtube videos, and made sure to get recommendations on what kind of ram to get (crucial 2gb). I took out the original ram that came with the macbook pro and put in the new ram. I screwed everything back in and then attempted to turn on the laptop. I heard the usual startup sounds but the monitor screen was empty and black and remained that way. I waited awhile (10 minutes or so) to see if anything would change, and nothing happened. I went back and took out the new ram, and put in the old one and tried to restart, and again, nothing but black screen. I tried taking out the old ram and putting it into a different slot and then the same thing for the new ram. Nothing. I'm trying really hard not to freak out (I have a lot of my stuff backed up on an external) but seriously, I have no idea what I did wrong and what's wrong with my macbook pro... and yeah. I am freaking out. Help? Edit: Edit to add that I am no longer under Apple warranty and the last time I had to deal with the people at the Genius Bar, I wanted to kill myself. Or kill them. If this is something I can't fix myself, could I also get some possible recommendations for people who fix these sorts of problems aside from the people at Apple?
