Question: MacBook cannot boot up, even in any recovery mode
MacBook prollate 15 late 2011.
I was using the laptop while charging and the laptop suddenly automatically shutdown. After open it back, the startup apple screen and login screen appears pixilated and the login field has purple color. After login the screen went from pixilated to normal Grey screen. After that it just stuck at there.
Booting into recovery mode also stuck at Grey screen, also Internet recovery mode, also with USB installer.
Please help and thanks very much before hand
