As has been discussed, it's good to clarify this.  Based on what you
say elsewhere, I think what you mean is that the graphical interface
is not responding to keyboard or mouse events.

Again, by "froze up" you probably mean that the graphical interface was
unresponsive.  There are other things one needs to do to know for sure
that the kernel has crashed.  Often, X will crash, giving a user at the
console the impression that the machine has "crashed," when in fact
the kernel and most other things are still working fine--that's one of
the benefits of unix.  Secret keystroke:  ctrl-alt-backspace will attempt
to kill the X server.  Often, it will succeed, dumping you back at your
login prompt.  If it does not, it's good to attempt to ping the machine
from another place on the network (assuming you are networked).
If you can ping it, you can often use telnet/ssh to access the machine,
then kill X/restart the machine/stop offending process (netscape?) etc.
A last resort option, still much preferred to pressing the reset button,
is the magic sys request key (a separate topic--anyone?).

I'll emphasize that what others are saying about checking logs, using
dmesg, etc. is very important for understanding the cause.

Hope these few suggestions give you some options next time.
