Hello everyone,
I have an early 2011 MBP 15" (10.10) and just a week or so ago, I encountered this lovely problem. So upon booting up the system, the loading screen goes up to a third and the screen goes white. I cannot start up safe mode and the recovery does not work either.
So I tried to use an USB with the OS X installer and I encounter the very same problem: it goes up to a third and simply turns white. I tried booting up a linux distro, but I cannot boot it up (quite early some error messages, might be an indicator for hardware issues).
I ran fsck, which reports me that the HDD is okay. I even unplugged the HDD and tried to boot from USB, which does not work either. I took out the RAM and checked them all, nothing wrong there.
I included a youtube video (http://youtu.be/mchMnbs1elE) of the verbose mode of booting up the computer and it seems to me that issue is the graphics card ("dsmos has arrived"). I heard that the AMD graphics chips in the 2011 series is faulty, but I do not get the typical stripes or anything. I wish I could just test the hardware components. I really don't know what else I could do. Maybe you have an idea? Maybe it is something else? I know that apple will want to have a lot of money to repair the computer...
Any help is greatly appreciated!
