Overheated Macbook pro
Hello,
My 13-inch Macbook Pro, Mid 2010 overheated when incredibly hot watching a movie a few days ago. The screen froze and horizontal lines appeared. I switched off the laptop and left it to cool down. Since then it has gone though a series of stages. Initially the screen would appear with a kernel trap , type 14 with the word "panic" (image attached). Now it is starting up normally, I sent a report to Apple and am writing this post on it. However, it has since frozen again when not especially hot. I am writing to ask for recommendations of what to do next.
I was considering a hardware test to try (this is proving tricky because of the model - holding D and then option-D were unsuccessful at startup) and isolate the problem and replace any damaged parts, as well as cleaning out the fan inside. Or perhaps backing up my laptop (doing this anyway) and restarting OS X (currently running El Capitan 10.11.6) Does the community have any thoughts on this matter? Just looking to prolong the life of a well-loved machine.
MacBook Pro 13", OS X 10.11
