Why is my MBP randomly shutting down after installing Lion?

    Quite frankly, Lion is a complete mess. I downloaded it and installed it over a Snow Leopard system that was working flawlessly and had never given me any problems.

    But after installing Lion all sort annoyances started to emerge, the biggest one has to be the tendency of my MBP to just shut down randomly, for no apparent reason whatsoever. To illustrate, here is what happens:

    1- Say I am using any application, Fireworks, Chrome, Espresso, etc.
    2- Out of nowhere, my screen goes black and the led light in the MBP turns off.
    3- But the computer remains "on" but I can't wake it up or anything.
    4- I have to force shut down the computer by holding the power button and then turn it on again.

    My MBP had never done anything like that before installing Lion. My specs are:

    MBP 15" i5 2.53Hz
    4GB of Ram
    500GB HD

    At work I use it with a secondary display, using both screens. At home i use it in clamshell mode. In both instances I use it with a separate Apple keyboard and mouse.

    Any help is appreciated.

    the lion nvidia drivers are flawed. it causes the system to freeze, crash, panic, lockup. especially with a external monitor.

    you can wait for the new drivers in 10.7.2, or run on intel only for a while, or remove some ~/library files every time you connected an external display or install the nvidia cud a drivers (this is rumored, i don't know about this last one) to work around this issue.

    problem is mainly present in 2010 mbp's with the nv330m

    I'm glad this isn't just me then. I'm having a similar issue. The only differences are I have a MBP 13" (2010 model), and it only just started recently doing it this week. It seems to do it just randomly too, but has only happened three times right now.

    check in system preferences if you have restart if computer freezes clicked.

    Nope. It's not clicked. It's been doing it randomly.
