There is a free program at http://www.pcmag.com/article/0,2997,s%253D1478%2526a%253D10165,00.asp called EndItAll that will do this for you and is highly recommended...the pcmag link is to version 2 and is more complicated to configure for a newbie than Version 1 listed below)
EnditAll Version 1
And also choose NONE for a screensaver until Scandisk and Defrag have been run successfully.
