Vista PC wont boot into windows

Hi - I have a Dell Inspiron, about 1.5 years old, that wont boot. Everything i've tried is not working. Heres what happens - start up, shows vista logo on the screen, then shows cursor for about 5 seconds, then reboots itself into this loop. I've ran a startup repair, that says that it found and fixed files, but still reboots itself, as if it did nothing. Wont boot into safe mode - I've removed all memory chips, nothing. I even used Acronis, created an image, used a new hard drive and loaded the image onto the new drive, thinking it may be the hard drive, but it still does the same thing. Is there anything else i can try?

I can boot it to the Dell diagnostic which has a memory tester, and all hardware is coming up passing. I can also boot to a Vista disc, but none of the repairs work without having to wipe the whole thing.

When you click f8 on boot up and choose the following from  the [advanced boot options menu] [disable automatic start on system failure] and report error message to EE.

here you go -
disable or disconnect aal peripherals and devices not needed for booting : extra disk, cd drives, ..from bios : lan,sound, ...etc..then try again
i suggest anyway to run ram and disk tests, to be sure about the basics; and uploading the dmp file helps too :
best download ubcd  ;

This issue may occur if the Security Accounts Manager file (SAM) is corrupted or missing.

This solutions is for WINDOWS XP. Hope it works for Vista too.
