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 .
try to repair windows if you have dvd
is there any beep sound?
I have been told that hard disk is spoilt. I did not hear any sound on booting , as in video link in query description. Please tell , did you view https://www.facebook.com/video.php?v=10152751645548594&l=1909898299141401193
well if it is hard disk problem then you can try to scan with Spinrite or HDDregeneration
