Chosen Solution
My macbook pro will start up fine( most of the time), but randomly my screen will go complete purple or green, sometimes with stripes, and then goes black. The computer is still on, but it’s completely unresponsive. It’s also very hot. One time the screen went straight black, and just beeped, without a pattern, until I did a forced shut-down. I also know that this started happening within the past week, before that I noticed my computer would turn on while sleeping in my backpack and overheat and be non-responsive with a black screen. what could be wrong with it??
Sounds like your problems are heat related so let’s go after that first. Take the screws out of the bottom cover, boot up and check to see if the fans are running. Next shut it down. Look closely around the end of the heat sink where it is crimped shut. You are looking for an dry oily stain on the logic board indicating the heat sink has leaked. Next lets change out the thermal paste: MacBook Pro 13" Unibody Mid 2010 Heat Sink Replacement Lets us know your findings.
I found a solution,! At least for my MacBook Pro (15-inch, Early 2011) Visit and install the software developed by gfxCardStatus. Is free and open-source. Here is the link: https://gfx.io/
