I turned my Vista off yesterday evening and today I turned my Notebbok on and now my Vista doesn't start any longer. The Bootscreen with the progressbar is shown correctly and now the Welcome page should follow, but only a black scrren with my mouse pointer is shown. I didn't install any updates or modified something. On 2 German boards several people have exactly the same issue. Does anyone here have also this issue and knows how to fix this without reinstalling?
