So I updated from windows XP to windows 10 and google chrome thenleft it on overnight so it could finish the download. Woke up the next day now every time I try and turn it on all it does it shows the start up loading bar and goes up to three quarters the way. He screen goes blank then shows the bar in the exact same place so basically it's not finishing the start up process. Please help!! Microsoft can't help and neither can Dell!!!!
