What is trouble of computer restart always after an openning of a program

First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

If you want help, you really need to provide more info. Does this happen with only one program or all? How old is your system? What version of Windows does it run? What program causes it?
