Is it the whole system that is hanging, or just the GUI? You can check
this the next time it hangs by hitting ctrl+alt+F1 (any key from F1 to
F6 should work, but for ease of communication and all...). If you get to
a text terminal then your computer is not freezing, rather the GUI is
locking up. Once it is determined which is actually happening, we can
focus on the right area.

Another thing you can try is re-enabling the 'zap X' key combo so that
if it turns out the GUI is all that is freezing, you can just kill the
GUI w/o restarting the whole computer. The key combination is hard-bound
to "Ctrl+alt+Backspace", so if you need this key combination for
something else, don't follow the directions below. otherwise... To do
this:
     1. Go to: System > Preferences > Keyboard | Layouts Tab > Layout
        Options
     2. Click the arrow next to "Key sequence to kill the X server" and
        click the checkbox next to "Control + Alt + Backspace". Be aware
        that from now on, if you press that key combination, your GUI
        will shut down, and you will return to the login screen.

Can you give a brief overview of what you went over with your tech
support person? This might help shed some light on what's working, and
what isn't.

Hope that helps!
