MacBook Pro Keeps Rebooting

    Yesterday, my MacBook Pro started acting up.

    For no apparent reason, it sort of pixilated -- though technically that's not what it did, but it looked almost the same -- and froze up. Twice, I forced it to power down by holding the power button off.

    Then today, it did the visual thing but rebooted.

    Then the apple came on, and it got about 3/4 of the way through the check and rebooted. It's looped.

    I tried to get it into safe mode, but it refuses.

    Thanks. But this doesn't work for me.

    This MacBook Pro does not have a removable battery, and as I said in my OP, it won't boot all the way up. It does nothing but reboot.

    A Late 2011, 15-inch MBPro, will likely be troubled by graphics issues.
    A failed graphics chip can exhibit a number of symptoms, one of them being unexpected reboots.
    Apple will replace the logic board to fix your MBPro free of charge. - check this page for details

    Good point above by @CoastalOR and @DeltaMac.

    You can still try to reset the SMC --

    Had anything else changed or been changed recently? One other option would be that you could try to put it into recovery mode and restore the operating system.

    I finally gave up and sent it to Apple, who had me send it in. I just got it back, with a new logic board. It seems to be working well again.

    Thank you.
