Quick update. I dont know why i did it, but i installed chrome and everything worked and it works a lost faster. All good for me. 
On the plus side it proves that it is capable of connecting to the internet & downloading

On the negative side it shows that there is something wrong with the IE setup. Internet Explorer is intimately connected with the inner workings of Windoze so I would strongly recommend that you don't let it connect to the internet until you have fixed it. Definitely don't use it for internet banking or eBay purchases.
I haven't got the patience to nurse sick Microsoft systems any more so I would wipe it & stick Linux on it but if you don't want to do that then at least listen to the bods who DO still have a lingering attachment to Redmond. Rebuild it (ie wipe it and re-install Windows).
Rebuild it
Afraid to say changing the battery didnt work. Still get nothing or warning comes up "cant find or cant open file"
Anymore ideas welcome.
Whilst the useless student is still localish to you, ask him to rebuild it. If the CMOS battery is shafted, I guess its old, probably not worth the effort to replace that battery.
its got nothing to do with date.. first you need to log in with admin rights.. re-build it.. then you will correct date-time whatever
