Macbook dead

[wareagle2334]

I need some help!

I have a Late 2011 MacBook Pro.

The other day I turned it on, plugged it into my 2nd monitor and it got to the password screen.

The 2nd monitor then turned orange and the MacBook had these green lines appear. I tried to reboot.

In regular boot it gets about 1/4 of the way and freezes.

I have tried to reset the PRAM and all that.

I have tried to boot in recovery mode and safe mode. It gets about 3/4 way and the screen turns grey.

I have tried internet recovery. It lets me choose my wifi. Goes through the stages and then turns grey.

I also tried to boot up with a boot disk I made. I can see the hard drive. Two hard drives are showing up and the install disk.

Neither hard drive will boot. The install disk takes it back to the loading screen and then it turns grey.

If the 2011 MBP is a 15" or 17" you may be looking at a dGPU problem ("Radeongate").

Force 2011 MacBook Pro 8,2 with failed AMD GPU to ALWAYS use Intel integrated GPU (EFI variable fix)

If you don't have time to read my story (which also describes some interesting technical approaches) just scroll down this thread until a "100% WORKING SOLUTION" text Discrete AMD GPU of my 2011 MacBook Pro 8,2 has finally failed because of the reasons mentioned here (...

What Coastal said.
Do you know what "RadeonGate" is?
If not, you'd better start researching about it.
Because I reckon that's "the problem" you have.

Final thought:
Unless the "easy fix" works for you (permanently disabling the internal discrete GPU), it's not worth fixing.
Time to look for something new.
There are some very nice prices right now on the MacBook Pro 16" ...
