Hmmm... They all seem to be linking up to the graphics chip (specifically the NVIDIA GT 650M). I would take a look at this and have Apple fix it. At the bottom it says that if you've purchased the computer in the last 4 years then you should be covered by the extended warranty. If you are still considered out of warranty, I would go to the Apple Store and complain specifically to a manager. If the product is known to be defective, then they should cover it.
Another thing you can do is use a software called "gpu-switch" by 0xbb on GitHub. I know someone who's used this before and it worked for him just fine.
