Macbook pro 2011

MacBook Pro "Core i7" 2.0 15" Early 2011

 

I'am using my macbook pro 2011 with Sierra and few days ago I was facing problem to use it.

Everytime loading image looks with glitchs, some strange lines. After a lot of research, I see some cases like this associated with the GPU (AMD Radeon HD 6490M), and after loading screen, still facing only the blank/gray screen and the cooling faster.


I tried recovery mode (CMD + R), internet recover, verbose, and safe mode...The only mode working is single user mode.


As I old/classic model, can't find official places for support, and I'm living in south america.

 

I don't want to waste this laptop, I'm trying anyway to change my radeon GPU to Internal GPU, but recovery mode isn't work, still blank screen.

 

Thanks in advanced any help!!
