As stated above, When I power on my 15: Macbook Pro Early 2011 (A1286), it does the chime and Apple logo a loading sign appears and disappears like normal, when that is finished it goes into a white screen and stays there...forever.

Extra detail: When the Apple logo appears, it has a strange yellow highlight, not normal. I have attempted every Macbook short cut available.

• Safe boot wil not boot.
• I've reseted PRAM.
• The hold D for hardware diagnostics does not run.
• Recovery mode will not boot.

I've unistalled HDD for a disk check up on a different macbook and everything was squeky clean. No problems. and booted as normal.

I've tried to boot my mac with my HDD in a adapter and still same problem. Apple logo and loading sign appears and disappears then white screen.

I've tried booting it with only one ram and alternating slots and ram, no dice.
