My MBP will not boot
MacBook Pro Mid/Late 2007, 2.2 Ghz, 6 GB RAM, 1 TB internal HD
MA895LL A1226
OSX El Capitan 10.11.4
I'm experiencing a problem where I cannot boot anymore. The symptoms are not always the same, I get 2 different scenarios:
- Sometimes I'll try to power on and the screen remains black, and the start-up chimes go every few seconds, as if it's continuously restarting itself.
- Sometimes I get varying degrees of progress, the Apple logo shows. Progress indicator gets about half way and then the graphics go berserk and the system freezes.
- Other times, the screen would be garbled with horizontal or vertical lines right from the start.
I've tried SMC resetting, NVRAM reset, booting into safe-mode, booting into recovery, booting to single-user mode. I also tried removing the RAM, re-seating them, trying one stick at a time in each slot but nothing works.
The only success I've had is booting into Target Disk Mode, which allows me to backup and run disk utility. Also ran Disk Warrior to rebuild the directory.
The laptop stays at work, never moves.
I've attached some pictures
