I have an acer 5742 lap top...I can't get past the click on user ...It says it needs a password but I never set up one...I use to click the picture and it would go straight to the welcome screen and then windows...Now it wants a password...I don't have one....I tried reformatting....the disk wouldn't load up....tried going into safe mode and it just won't...just gives me no screen and just sits there...How can I get back into my laptop?
