    You can replace the ic, rewire the bread board, change the program, etc.

    Exactly. If "nothing works" - use "divide by two" approach. First check against software error by using other, proven to work, test code. Like LED flasher example. Other option would be - to load your code into proper development board like LaunchPad.

    Assuming no hardware defect (or breadboard wiring error), the most common cause for a reset loop is the watchdog timer. If you don't kick it at regular intervals, or disable it, it will reset the MSP.
    Other common causes are stack overflow (especially defining more local variables than the MSP has ram), eternal recursions, and, and, and...

    You should provide more details than "my undisclosed software on my secret hardware causes a reset (when I do something I don't tell you)"

    The breadboard has a very high capacitance, your Restart/NMI pin will be triggered by neighbor switched outputs or circuits.
