Did the diagnostics pass the RAM and the hard drive.
You should check the BIOS settings to see if the hard disk is detected, if possible reset the BIOS back to the default settings and see if the computer boots up.
If not :-
Then it appears that the operating system is either corrupted or system files were deleted or infected with viruses.
Your only option is to do a operating system repair or a complete new install of Windows.
I recommend you do a new install.

Remove BIOS battery. Short BIOS jumper or leave the battery out for a long time(Over night,maybe) This should default the BIOS to having no pass word present. If that doesn't work then evidently Dell has one within the BIOS . Just ask them.
