    It could be a RAM usage....That is a lot of resource heavy applications to be running at the same time with only 3GB of RAM....I'd upgrade it.

    I was having freeze ups on my laptop which I "fixed" by removing a mounted SMB share, that I really didn't need.

    When you reboot after a freezup, checking the /var/log/kern.log can be very useful.

    Anyway, my laptop stop freezing at the moment (2 days without issues). But, i'm paranoic saving everything all the time, quite annoying.
    I have been running 12.04 with kernel 3.5 for a couple of days with no freezes.You can install the 3.5 mainline kernel over the top of the ubuntu 12.04 kernel without reinstalling(always wise to have a backup regardless).

    Follow the instructions here

    If things don't work you can go back to the previous kernel by holding shift at the grub menu and choose previous version from there.

    The freezes could be a sandy bridge issue(i am using asus p8p67pro board)

    Re: Ubuntu 12.04 completely freeze

    After some tests, i can tell you one thing:

    The problem is related with virtualbox. I can tell you this because i didn't need to open virtualbox in a couple of weeks (i need top open it for some specific jobs). i didn't exèriment any freeze those days.

    But, a couple of days ago i opened virtualbox again (some work to do) and voila! the freezes appear again.

    Maybe it really is a RAM problem, in which case i will buy some more.

    Thanks to every of you guys.
