    It was working fine yesterday. Now, it's trying to boot (the grey screen with the apple logo) but there's a progress bar at the bottom which takes 10 minutes to fill up. After 10 minutes, the computer just shuts off and if I try turning it on, it does the same thing.

    Tried to boot into ubuntu using an SD card but it does the same thing. I then went into internet recover and repaired the disk. still the same thing.

    I have the same model MBP and haven't had any such issue, it actually runs rather nice with Yosemite.

    The only problem is perhaps a interrupted install that may have affected your boot partition etc. The last few downloaded updates I had let them do their thing and with a bit of patience (the Core 2 Duo is "old" by computing standards).

    Have you tried booting from your original OS X install DVD? Worst case scenario is to fully nuke the drive and restore from a retail install DVD (Snow Leopard) and then download and install Yosemite. I hope you back up often... :confused:

    I've been having the same issue since upgrading to Yosemite, have "fixed" it twice but had the issue happen again today.

    I've kept a note of the steps I've taken to gain access again. I don't think this can be deemed as a fix though:

    1- Reset NVRAM (Cmd/Option/P/R at boot)
    2- Select Boot (Option) with ethernet cable.
    3- Boot Yosemite installer via USB

    -- GREY SCREEN for 15+ mins -- Turned MBP off

    4- Boot from Installer (C) with no power cable plugged in

    -- After 60 seconds got redirected to login even though USB drive was making noise --

    5- Enter credentials and logged in

    I'm starting to think that this might be linked to applications trying to open on load. Will post any updates if I get any.
