Two videos which illustrate the problem with my Dell XPS 8700 Desktop Computer. The videos may take a minute or two to download.

The first video shows the templates page when you open Microsoft Word. Upon opening the programme the scroll bar on the right hand side of the screen, runs down the screen to the bottom until the last row of templates is reached. At this point it is not possible manually move the scroll bar up the screen in order to access the first row of templates.

The second video shows a similar problem with Microsoft Outlook. Upon opening the programme the messages scroll bar runs down the screen to the bottom until it reaches the earliest post. Again it is not possible to access the latest post manually. The only way to fix this problem is to power down and restart the computer. This problem may be temperature related. When I had central heating on in the house it seemed to happen about every 2 hrs. Now it happens about every 6 hrs. In this mode the computer is unusable as every programme is affected like this.
