It's probably not shutting down, but restarting.  Look at this site for possible explanations and resolution: http://aumha.org/win5/a/shtdwnxp.php

Also check the power on/off button to see if it is stuck in one position.  You can switch the connection with the reset button to test this.

You need to replace the fan - it's sounds broken.  It's probably a 3-wired one, and you need one of the same size as the original so that you can install it in the same location.  If you have an AMD cpu, this has to be done or you will burn up the cpu, but Intel cpus need it too.
