I have read the points you suggested, thanks for your help, I know the Windows 8 is activated, downloaded the trouble shooter which identified a driver problem, used IE to start the computer generally use firefox, and am still frustrated because no mail is downloading on the tile, but is on my login account. so ready to remove the tile and work with the login
after reading all I had to do to try to fix the problem, I decided to leave it, too complicated for me to bother, and today 2 weeks after it first stopped its back working,
