Start And Shutdown Computer Automatically Several Times Per Day?

What I need to do is turn on a Windows 7 computer every hour for about five minutes and then turn it off again automatically; while the computer is on I have to run a macro. The cycle described before has to be repeated 24 hours, so, the computer is automatically turned on, it automatically runs the macro and when the macro ends, it goes off again 24 times per day. When I say �turn off� I mean, either turn off the computer or send it to a low energy consumption state like hibernation or sleep� Basically I know how to automatically turn off the computer and turn it on once per day using the BIOS setup, but I don�t know how to do this several times in a day automatically and then call the macro every time�
