    That does not sound like a kernel issue, although it could possibly be.

    Next time it freezes - while it is still frozen - press the caps lock key. Does the Caps lock led toggle ?

    Maybe the logs have some clues.

    After it returns from being frozen (do this as soon as possible after the freeze) , open a terminal and

    tail -n 150 /var/log/syslog | pastebinit
    tail -n 150 /var/log/Xorg.0.log | pastebinit
    Post back both URLs display on the command line back into your next post.

    During the freezes, what is your CPU usage ? Disk IO usage ?

    You can check with top and iotop. You may have to install iotop.

    sudo apt-get install iotop
    Keep them running in a terminal while using the PC.

    Kind regards

    Thank you for your help. I ended up solving this by upgrading to Ubuntu 13.04.
