    What updates are you talking about?
    Does it also happen in another, even temporarily created, user account?

    Did the computer ship with Lion or was it upgraded to Lion? If it shipped with Lion and 10.6 was brute forced onto the system, the hardware may be incompatible with the software and the fix would be to reinstall Lion using Internet Recovery. Otherwise, see if any of the information here is applicable to your issue.
