Description of problem:
Once the system is up and running for a short while, what ever application that
is running will just close.  After that, when every one tries to start another
applicaiton, it begins to load, but before it actually opens up as a running
applicaiton, the window just closes and disappears.  At this point, one has to
reboot the computer and it will work for a short period of time and then the
same thing happens again.
