I haven't tried System Restore as yet as I was hoping it might be a simple task, but it is probably a better solution. Out of interest I downloaded SP3 on Wednesday and my comp has been acting strangely, freezing, slowing down, ending programs. I have been looking at some of the problems others have had with SP3, this morning, but did not see the problem that I currently have, which is why I posted. I also tried to uninstall SP3 and it came up with a list of other programs which it said may not work if I continued, so I stopped. I shall now do a System Restore and let you know. Thanks.
