Last month I upgraded the RAM in my early 2011 MBP from 4gb to 8gb using Crucial memory. No issues whatsoever, but I figured more might be better to help my machine run a little bit faster. I returned the 8gb and upgraded to 16gb. After installation I ran tests to ensure the memory was working properly and everything passed. The machine runs just fine. However, when I close the lid and the machine goes to sleep, it does not wake up when opening the lid. I have to press and hold the power button and the screen will turn on however it is fogged over (for lack of a better description) and there are a row of tic tacs that fill in at the bottom (see pic). Once all the dots fill in nothing happens. I need to once again press and hold the power button and manually reboot the machine. This does not happen if I leave the lid open and the machine falls asleep on its own. What is causing this and how can I fix it? Thank you!
