'morning everyone ... thanks so much for all the advice and suggestions re our tower/hard drive. We're currently in the process of mulling all this over, and will speak to our little computer mechanic man when we get back from hols. As far as backing up all our Word documents, etc ... er, um, well I think that's a lost cause - and that we might well lose a whole bunch of stuff, but our computer man is very reliable and good and he will definitely do his best for us. I think that, given the age of the tower itself, we will just bite the bullet and get a whole new one, including a new hard-drive. We've got all the disks for re-installation, so that won't be a problem.
Thanks again everyone for all your help,
Have a great Thursday ... Chox.
