In reference to the stack overflow problem the link below does not address the VXD possible problem, but might help expanding the "stack space". http://support.microsoft.com/support/kb/articles/Q149/0/83.asp 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".
