I am trying to determine why the fan will all of the sudden start running and sometimes it will not stop until I manually shut down the computer.

Which fan is it (graphics card, CPU, Special case fan)? Also do you know what temperature your various components are running at (If you do not have a utility to read the temps download Everst Home or SpeedFan from the Freeware Replacements for Common Commercial Apps section) ?

If the fan has a three wire connection then is should be temperature controlled, if it's a two wire connection it could be do to a loose connection.

Your computer may be running too hot. Have you cleaned inside the case recently?

Even if a fan is temperature-controlled it should never stop - it should just spin slower, typically at 1/2 to 1/3 of its max speed. Any fan that does not start spinning when power is turned on is faulty and should be replaced. This should happen within a couple of seconds when powered. If it takes longer than this then that is a sign that the fan is binding and needs replacement.
