WIndows 7 hangs up at the Welcome screen

Windows 7 came pre-installed on a Dell Laptop.  System boots fine but regardless of which account I select the system goes to the "Welcome" screen and stays there forever unless I press "Ctrl-Alt-Delete" and then startup continues to the desktop.
Did you make any changes to the computer lately?
First of all check if there is any external devices connected to the computer, if yes remove them and check.
