Windows won't shutdown

[Robert Robinson]

On an HP Pavilion 750n with Windows XP Home and every security/update patch
applied, short of sp2.

Odd situation, as the operating system actually does shut down (even the hard
drive stops spinning), but it just doesn't signal the Power Supply to shut off
(ATX) leaving it at the "Windows is shutting down" screen.
I'm thinking that the dll's registry entries that signals this event has been
corrupted, and if I can find out which one(s) it is (dll file), I can un and
re-register it to re-establish the correct registry entries.
I have tried all of the Knowledge base walkthroughs on troubleshooting
shutdown problems to no avail. Uninstalled many programs that I know have
caused problems in the past and am now seeking your help!
My last ditch effort will be to do an in-place re-installation of XP, which
of course will make me have to re-install all of the security updates and
patches again. Another option is to do a hardware rebuild, somewhere I read
about command line switches that will cause XP to rebuild it's hardware registry
hive - something like "winnt32.exe /n /hr".

Just a note that I missed in my original post: The system does shutdown
properly in Safe Mode.

I have already tried all of the suggestions on Mr. Eshelman's site, to no avail.
