Windows XP Pro shutdown no longer switches off the PC

My daughter has an HP Compaq nc6320 laptop with a Core 2 duo processor (1.83Ghz) and 1Gb of RAM.

I have just learned that for some time the PC does not power down automatically. The message "Windows is closing down" appears and then disappears leaving the the standard pale blue screen with the HP logo. The PC keeps running until manually switched off. ACPI is on and I have tried setting "PowerDownAfterShutdown"="1" in the registry all to no avail.

I would welcome suggestions on how to solve this short of completely re-installing Windows.

Have you tried emailing their support department?
If it was usual for the Windows to shutdown and automaticaly power off the computer and now it shows:
It is Now Safe to Turn Off Your Computer

Then check this:

http://support.microsoft.com/kb/810903/en

If it stays saying Windows is shuting down and never shutdown then some process if failling to terminate.

Try this to force Processes and services to terminate on shutdown:

Go to Start > Run.
Type regedit in the Run box then press Enter.
 In the Register Editor window go to the path HKEY_CURRENT_USER\Control_Panel\Desktop
Double Click on AutoEndTasks which is in your right hand.
Change the data value to 1 then click OK.
Restart your computer.


If the issue persists:

Go to Start > Run.
Type regedit in the Run box then press Enter.
 In the Register Editor window go to the path HKEY_LOCAL_MACHINESYSTEM /CurrentControl Set /Control
Double Click on WaitToKillServiceTimeout which is in your right hand.
Change the data value to 2000 then click OK.

 In the Register Editor window go to the path HKEY_CURRENT_USER \ Control Panel \ Desktop Set /Control
Double Click on WaitToKillAppTimeout which is in your right hand.
Change the data value to 2000 then click OK.


If the values do not exist then create them.


Cheers

The laptop has autoupdate on and has a permanent ADSL WiFi connection when at home. SP2 was installed before delivery and SP3 has been applied since.

Thanks to all for the suggestions, we will try them and report back.
Lengore--"The laptop has autoupdate on".  I understand that to mean Windows Update.  That could very well be the reason/problem for the hang on shutdown.  Some Updates can take some time to accomplish and in some cases (those requiring interaction) may never finish.  
Try changing the setting in Automatic Updates to "Notify me but do not automatically download or install".  Your daughter will then get a notice in the Status Bar when Updates are available and can choose the time to go to the Windows Update site and get the Updates.

Thanks to all who replied. SFC /SCANNOW did the trick although it did not require the Windows installation disk. On my desktop I ran SFC /SCANNOW and it asked for the installation disk several times, even though I left the disk in the optical drive! I'm delighted it solved my daughter's problem.
Lengore--You are welcome.   Glad to hear all is well.
FYI--The difference you and your daughter experienced when running SFC /SCANNOW probably has to do where the I386 folder is.  In your case it seems it was on your WinXP CD.  In her case it probably was put in C:\ or C:\Windows by the PC maker.  That folder is one of the main sources SFC uses to restore files.
