Hi, I have tried every solution i could find, none of which worked..mabye you guys can help. So my macbook pro just won't start up. This happend 2 days ago and ever since If i power it on normally - it gets to the apple logo and about half full loading bar and freezes. If i power on in safe mode OR recovery mode with cmd+R - i see the apple logo and bar for about 30 seconds and then blank white screen.. the fans are either working hard or quiet. I have tried just about everything: Reseting PRAM and SMC, FSCK, I've tried booting from an external usb drive -booting with option key - but when i choose the external drive, the same thing with safe mode happens - apple logo and then white screen. I have no way of reinstalling the OS... In the past few days, while it was still working, the mac did unexpectedly restart once in a while(i never saw it happening but i had to log in and saw the error). Anyway, if anyone has an idea of what might be the problem, Please, reply its a macbook pro early 2011, with added 8+8 GB RAM, and an SSD. I can upload pictures if you guys need or even videos of the problem. Thanks!
