I am using Windows XP. When I plug-in or turn on the laptop, I get a white screen saying "We apologize for the inconvenience but Windows did not start successfully. A recent hardware or software change might have caused it." Then there's a list of options: Safe Mode, Last Known Configuration, Start Windows Normally. It further goes on to tell me which option I might try. Then at the bottom of this dialogue there's a 30-second clock. When it times out, it goes to the Windows icon screen, then the manufacturers screen. However, it then goes back to the first screen. This becomes an endless loop, even when I try to select the options listed. It does this forever.
