Having had problems with the computer, I decided to reinstall XP Home over the top of the original installation, thinking that all existing files etc would still be OK. I have done this several times before over the years with little or no problems. This time being the exception. After a deal of a struggle I got XP back on, all the existing programs show as being there but accessing them is the problem. Like AVG it is installed on the HDD but where is it, I can't reinstall it without deleting it first.
It is similar with other programs.
Can't find the Modem either, and haven't been given any driver disk for it.
Any advice will be gratefully received.
Otherwise it looks like a full format and start from scratch again.
