Hi to everyone. I have a problem and I need some advice. I have a Dell Inspiron 1545 with Windows 7 Home Premium. It refuses to start. It goes as far as the "Starting Windows" page, and that's it. The coloured Windows logo only half forms then it goes to a start up repair page that doesn't work either. In fact nothing works. Not even startup repair software. I'll even un-install then re-install, but I can't get hold of a installation disk. Wrong type of product key. Desperate. Neilo.
