This PC has been refusing to power off when told to shut down for a couple of months.

All power settings are normal. Its a desktop and the usual standby and hibernate for laptop modes are not applicable.

Anybody have any other explanation? I want to exhaust all possibilities before trying replacing the power supply.

Give us more information:
1.Motherboard modle
2.When did you notice the computer started doing this
3.If you go to start shutdown will it turn off
4.If you hold the power off button on your tower will it turn off
5.It may be a courrpted system file
6.Can you Logoff->Shutdown

Try This:
1.Boot up in safe mode (While computer it starting up tap F8 a couple of times)
2. Then while logged in as an admin in safe mode try to shutdown

yse it does sound like a corruption in system files. if you have an XP CD then try running SFC /scannow

Start > Run > "sfc /scannow" (minus quotes)

1. Board: KM266-8235
Bus Clock: 133 megahertz
BIOS: Phoenix Technologies, LTD 6.00 PG 09/09/2003

2. About 6-8 weeks ago. Just assumed it was a bug in a MS update but it has not gone away.

3. The only way I can shut down other than pulling the electrics is holding the tower power button for 7 seconds which I do at the point where restart normally occurs and this cuts through the restart process

4. If I hold the power button down while at the desktop it will crash windows so I tend to avoid this unless hung. But see 3 above.

5. Yes

6. No. Logoff first followed by shutdown (used to work for network hangups as I recall) makes no difference.

7. Safe mode does not cure the problem.

Question for DemonSui

I do have an XP CD but how should I use it ... if I go Start > Run > sfc /scannow where should the CD actually be?

If the CD is in, say, drive D: then are you saying I should invoke...
Start > Run > d:sfc /scannow?

Sorry to be thick but I am not completely sure what you are telling me to try.

Just ran sfc /scannow. Ran through no problem and did not ask for a CD.

Miserably, the PC is unchanged and still thinks a shut down means restart.

Any further suggestions?

Could you tell us exactly what happens whe nyou try to shutdow without holding tower button

Also try this

On starting up , tap function key f8 repeatedly until you break into the windows startup mode.

Choose to go into safe mode .

Browse in safe mode just to establish with the system that you are there ,then shut down.

On coming out of safe mode windows will make a new shutdown file .



If this was the problem , then starting up will be o.k. but with a mostly blank preferences settings .

Just reset to your own likings and shut down again.

Shut down behaves like Restart. Exactly. i.e. "message .. saving your settings "... wait a bit... bit of blue screen, finally monitor black - no signal Then in a second it starts whirring and comes back again.

I'll have a go at browsing about in safe mode for a few minutes before shutting down and see if that makes a difference. But this is getting like zapping zombies that spring back at you from nowhere, if you get my drift.

Have you checked your fans
1. Check your Case fan
2. Check your CPU Fans
3. Lastly make sure your memory and power supply is still functional

Most random shutdonws are caused buy structal problems or over heating

Hi Siggyman

The machine is definitely not overheating. The memory is fine. And most important of all this is not a random shutdown I am trying to resolve.... it is a REFUSAL to shut down. Maybe the machine is just too cool?

Sorry if that sounds a bit of a sense of humour failure... just that this is really a very minor irritation but it would be nice to get to the bottom of it!

Yes - 100%.
Also clean of viruses and spyware.
No other malfunctions known.
Maybe there is a connection loose or broken or some controlling part of the power supply? I reckon next step is swap power supply but I am not sure I can be bothered right now....as long as the button keeps working.
Any other ideas do let me know.
Thanks

I suspect it's a corruption in your Windows files (those that aren't "protected" (which the SFC tool scans)). It could also be driver corruption issues, bad hardware, or a host of other things.

To check for obvious problems with your drivers, go to Start...Run...and type in "devmgmt.msc" (without the quotes) and press Enter. Look for any red x's or yellow !'s. If you find any, then update those drivers.

Also, check in your Event Viewer for errors related to the shutdown process (Start...Run...type in "eventvwr.msc" (without the quotes) and press Enter. Click on the Application and the System categories in the left hand pane - then check for errors in the right hand pane. Let us know what errors you find.

Any further driver troubleshooting will involve uninstalling and reinstalling all of your drivers to see if this corrects the problem.

Or, you can try a repair install of Windows XP. While this is a rather drastic solution, it has worked for me in the past. Try a repair installation of XP using these directions: http://www.michaelstevenstech.com/XPrepairinstall.htm

Try this just for grins and chuckles.
I've been using for over a year. whenever an app. hangs,I'll use this before I head to the power button.
There is also "superfast reboot"
