In reference to the stack overflow problem the link below does not
address the VXD possible problem, but might help expanding the "stack
space".

In reference to the heating problem, I don't have a definite answer but
a "try" would be a single power source for your computer. In other words
if you are connected via a surge protector or APC along with other
peripherals, unplug the computer power chord and plug directly into a
wall power source. This may give a better power source to see if the
problem persists. Again just a "try".
