XP Home boots, immediately starts shutdown, hangs

Compaq Presario SR1215CL, XP Home

My friend added a DVD R/W about a year ago.  A month ago, she says she did a system restore.  I asked if she unplugged the newer DVD R/W prior to restore.  Nope.  So now it won't boot.  Here's the details.

Starts to boot, goes quickly to normal shutdown screen (blue, logo, hangs right before "Saving personal settings" and "Windows is shutting down" usually appear).  Safe Mode and Command prompt to the same thing.   I've tried several things, still same problem.

In Recovery Console
 chkdsk /r (Found and fixed one or more errors on volume)  
 fixboot
 fixmbr

I attached the hard disk to my computer-
 Trend Antivirus on E: (passed)
 Scandisk (passed)

I checked autoexec.bat, config.sys and boot.ini -

...BOOT.INI
[boot loader]
timeout=0
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /noexecute=optin /fastdetect
C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons

aha!  so I edited it to look like boot.bak (see below)

Boot.ini
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /noexecute=optin /fastdetect

But still no boot.  Any ideas out there?  Been there, done that?  Thanks for getting this far.
