I have an early-2011 MacBook Pro. Several weeks ago swapped out the hard drive for a SSD and added 16GB of RAM (purchased from Crucial), both of which are supposed to be compatible w/ my model. Since then, it has seemed to work fine. Today I was surfing the web, reading an article w/ an embedded video. All of the sudden the video stopped working, as if I had lost my internet connection. I checked the Wifi drop-down, and it looked really strange. It had all this text I have never seen before about "AirportTurnOffKey," etc., and no Wifi network was checked off. Then when I looked back at my browser tabs, they were acting bizarre (as seen in video). I closed out of everything and then noticed my computer's menu bar was blinking. I force shutdown, restarted, and now it seems to be running fine. The fan is running. I ran an Avast virus scan, which turned up nothing.
