Hi Pauline, Try this: 1. Go to the start menu. 2. Arrow to "run" and press enter. 3. type in the following exactly as I write in below: Defrag c: /r And press the enter key. Now just leave this running for as long as it takes which could be anything from 1 hour to 4 or 5 hours depending on how bad the hard drive is fragmented. When it finishes it will say so and to exit out of the black coloured screen which by the way is called a "command prompt screen" just type in the word, exit and press the enter key. Good luck, Paul. -- I am using the free version of SPAMfighter. We are a community of 5.9 million users fighting spam. SPAMfighter has removed 52 of my spam emails to date.
