Well, tonight I noticed my pb was running a little slow. Checked the RAM and it only showed 512 (ordered 2 512 sticks). Thought ok, I'll just check and see if one of the sticks had come loose. I pull the cover off and pull the sticks out and put them back in, turn it on, and it still only shows 512. Well, switched the sticks (put the one on top to the bottom and vise versa). Started it back up and still no difference. So....now I've come to the conclusion that it's a bad slot. I bought this new in Feb when the new ones came out, don't have apple care. What are my options?
