Why is my MacBook Freezing up?
At random times my mid 2012 13 inch MacBook Pro will freeze up, with 5 sets of dual horizontal lines about an inch and half wide showing. If I'm plugged in and unplug, the computer shuts down immediately. If I'm running on battery power, I have to close the top and it takes about ten to twelve seconds for it to shut down. It makes a static-y clicking/popping sound for that ten seconds, then shuts off. I can then restart.
This happens at apparently random times. I'm not hitting the track pad or any specific key, and it has happened while I'm not even touching the unit. I have a photo of the screen if that might help anyone diagnose the issue. It is starting to happen more often now. Any ideas?
