Thank you GX1_Man for your comments - there is no vital data on the laptop,
i can start afresh, the original hard disk was damaged and a replacement obtained from ebay, this has been checked in situ with Scandisk and seemed ok, i cant access the net (via this machine) to download any drivers etc.
Although i changed the hard disk myself i am obviously not a techie and if this is a major hardware problem then perhaps i have a 'junker' !
