Can you verify that the kernel is alive? Can you login from another machine 
using ssh? Does the machine respond to a ping?

If you use GDM/Gnome, ctrl-alt-bs is disabled, IIRC.

I would guess this is an X issue. And typically due to a bug in graphics 
drivers. What video hardware do you have? What drivers do you use?

When it happens again, I would take a look at /var/log/Xorg.0.log (if you can 
ssh from a remote machine) or /var/log/Xorg.0.log.old (if you cannot and have 
rebooted into runlevel 5 again). If X got hung, something there should give 
you a clue what happened. If you post the log here, maybe we can help more.

HTH, :-)
