When you boot up your system it goes through POST, then the external drivers are loaded, during that process the Discreet GPU can come up in a failed stated so your system isn’t able to show an image either internally or externally. To over come this we need to disable the Discreet GPU so the the intergraded graphics engine within the CPU is only used. It won’t get there on its own.
The easies way is to restart the system in Safe mode so the drivers don’t load. You may need to reset your SMC as it can get locked. Then install this app [https://gfx.io|gfxCardStatus] it will allow you to disable the Discreet GPU.
If you have a second system you can also use target disk mode between the two and then delete the Discreet GPU driver. That last way is to alter the systems firmware [http://dosdude1.com/gpudisable/|DOS-DUDE - Disable MacBook Pro Dedicated GPU]

If you really need the better GPU you’ll want to look at replacing your systems logic board with a much better one! The issue you are facing is only a problem with the AMD GPU Apple used. In the 2012 modes Apple jumped to the NVIDEA GPU which does not fail from overheating like the AMD as its a newer design that can handle heavy work flows without overheating!

I’ve swapped out over a dozen 2011 models to 2012 logic boards. There is a small modification needed to the LVDS cable otherwise is a direct drop in!
