BSOD at Boot-Up / Windows XP Professional

I've got a Dell Latitude D600, running Windows XP Professional. Recently, the computer stalled at start-up and displayed the error screen that the system was unable to complete the boot-up. The next attempt at start-up and the selecting the option of using the Last Known Configuration That Worked, was unsuccessful also.

Fortunately, I had fairly recently upgraded the hard drive, so I reinstalled the other hard drive (which worked) and using an external hard drive interface, I was able to access and read the new, non-working drive. All the information appears to be intact, including all the system and data files. I've made copies of the files from the non-working drive, so that worst case - I can reinstall the operating system.

Using the original Dell system disks, I booted from the CD-ROM drive, and used the option of attempting the Repair of the setup files (not using the Repair option, but the standard setup option, where the disk reads the current installation, and allows you to only reinstall the start-up files), so that you could boot to Safe Mode. I'm certain that there is a good Restore point that might have been established within an hour before the problem occurred, so it might be nice to be able to get back to the Desktop in Safe Mode, and access the prior Restore point.

The reinstallation of the setup files seemed to be partially successful, in that I was able to nearly get to Safe Mode (the screen showing Safe Mode loads, but no icons will load - followed by a dialog box that simply showed: Windows XP Setup. Windows XP setup cannot run under safemode. Setup will restart now.

At this point, nothing appears to have been done that is irreparable, and since I can access and manipulate files on the non-working drive, and I'm running the same O/S configured for the same identical computer hardware, seems to make a number of options available. I will say that just copying the O/S files from the older working drive to the non-working drive is not my first choice, since the working hard drive O/S has gotten incredibly s-l-o-w at boot up, after a number of years. So, while it works, the best option would be to try to restore the O/S on the newer, non-working drive.

I've recorded the error message: STOP: 0X0000007E (0xC0000005, 0X00000000, 0xF78A9F18, 0xF78A9C18)

So, the clean reinstall is an option, but if there are other file replacements or manipulations that could be attempted, I'm willing to try any advice that might be offered.
