For a couple of months I've had a problem with my screen scrolling or jumping by itself when I've been using Outlook Express, Word, Excel or when I've been web browsing.
I've tried just about every program to scan for spyware, malware and viruses but they all keep coming up clean so I don't think there is any infection.
I've also uninstalled and reinstalled Microsoft Office and checked all the connections to my PC for the monitor, mouse, keyboard etc with no obvious problems being found.
The problem occurs whether or not I'm connected to the web. Other applications seem to be free from the problem.
Can anyone help please?
