I have tried clicking start then all programmes then accessories then system tools then system restore and all that pops up is a blank box with system restore at the top. I have used system restore on this computer before but now it seems to have disappeared! Also when I click start then help and support nothing happens at all! I am having probems with my e-mails and that is why I wanted to system restore. My computer is a Packard Bell running windows xp media centre. It was bought new at Christmas. Any ideas please?
