Why does my Compaq Presario CQ42 display the startup screen repeatedly without proceeding into Windows?

How can I resolve boot error on a  Compaq Presario CQ42 laptop with Windows 7? The laptop loops through the start screen repeatedly without starting up Windows. On pressing Escape , there were options of System Diagnostics – Start run test , System memory test and Hard disk test which I did but error did not resolve the problem. I posted a video showing the problem at https://www.facebook.com/video.php?v=10152751645548594&l=1909898299141401193 .
