PC will not power off even though I changed the regedit value to 1 in winlogon.
Also tried http://support.microsoft.com/kb/315664. There were 4 or 5 USB Root Hub listings in DM. I unchecked all of them and nothing changed.

Can anybody offer another solution?

Tried the following fix; nothing changed:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"PowerdownAfterShutdown"="1"

Have you done Malware scan? I have seen Malware cause this issue. Other than that no ideas.

Sorry

Malware, Spybot, rootkit, you name it, I've run it. I'm thinking perhaps there is another registry key to fix or replace the system file that controls it.

When you say will not power off.
Do you mean that:
It never starts to shut down and stays in windows?
It says shutting down and never finishes?
It shuts down and restarts?
?

I know you know what you mean but there are several scenarios that could cause someone to say it doesn't shut down.

Thanks
Roger

PC will not power off after it shuts down. I have to sit and wait until a message infos me that I can now turn off the power.

BTW, this power off problem is different from AlreadyTaken's system shut off problem. Mine PC is a Dell OptyPlex with Windows XP sp3. This problem started after a crash that required replacing the hal.dll.

For reference mine shows in XP Pro SP3
Location C:\WINDOWS\system32
Size 131 KB (134,400 bytes)

Version
5.1.2600.5512 (xpsp.080413-2111)

Where did you get the hal.dll from?

Since it started after you replaced the hal.dll that sort of points to the cause.

Windows key + R for the run command
type cmd to load the command prompt
and see what happens when you run
sfc /scannow
That will run the system file checker to locate changed, corrupt or missing system files.
You may need your XP disc.

Good Luck

The hal.dll installed now is the original off the sp2 disk. Combofix.exe probably got it from one of the caches on my PC placed there by Dell during the original setup. I assure you, I don't replace system files unless required. My system crashed and replacing this .dll was required in order to be able to boot up. My problems began as a result of that crash.

I, too, use XP Pro sp3 Version 5.1.2600.5512. Can you tell me the date on your hal.dll? There is a more recent one that I found in MS's sp3 files. I ran sfc /scannow days ago. I first had to create an sp3 install disk using slipstreaming. sfc /scannow did not provide a .txt or .log file to show what it fixed, if anything. Do you know how can I get it to produce such a file if rerun it?

Thanks.
