This is why I always buy AppleCare. Unfortunately, I have had many issues like this with my MacBook Pros. I've been through 5, ranging from 2009-2013 and of those 5, 3 were replacements. Each machine went through thousands of dollars in repairs before Apple finally replaced them. All were either logic board issues or a careless and sloppy Genius install.
Same with my iPhone. I have had 3 models (4, 5, 5s), and the 5 was the most problematic one I have seen yet. I had 15 replacements before Apple offered to replace it with a 5s if I traded them my phone and paid the subsidy price.
The only one device I have had almost no issues with are iPads. I have had 3 models of the iPad (1st Gen, 2, and mini 1st Gen). Of those 3, only 1 was replaced (the iPad 2). It was replaced 2 times due to screen issues (original had horrible light bleed, the other had a defective LCD panel where I could see this one green dot that was about an inch in diameter), otherwise the others were fine.
Point being, I've been in your shoes. I have come to realize, they are electronics, and they have issues. If you are in the US or Canada, call AppleCare and ask to speak with customer relations. Tell them your case, and ask if they could replace your logic board. Usually, since you are only 2 months outside of warranty, they should have no issue covering the defect but your milage may vary.
