Upgraded the whole machine,new Phenon quad core 3.4 ghz 4 gig ram,Geforce 9400 1gig graphics card new hard disk with clean instal from my winxp pro disk,ere come to think tiz a new desktop case as well so tiz really a new machine rather than a upgrade,only kit from old machine was the graphics card.
Possibly the first time I have tried to access microsoft website on this machine.
Lots of stuff about the prob on the web,reading and trying to understand,could be summat to do with my settings.
My XP disk is pretty long in the tooth,that's why I had to download SP2 then SP 3
