It beeped a few times and than just a black screen, I then pressed the power button again and it booted up normally. I checked and it does infact recognize the ram I put in and looks good on that front. Is it possible that I maybe updated a few things on my computer before I powered this off (which I hardely ever do) and it is just telling me that? I am running Lion on a Early 2011 Base 15'' Model Thanks Guys! ---------- PNY ram by the way ---------- Anyone?
