PC keeps restarting on shut down - WinXP

[Ben]

I am running WinXP and recently (about 2 weeks now) my PC restarts/reboots
straight away when I shut it down.

So basically what I do is go to Start - Turn Off Computer - Turn Off. As
soon as it boots down it boots right back up again as if I clicked on
Restart instead of Turn Off.

What I have to do to shut down without it rebooting is to turn it off by
flicking the switch on the power supply at the back of the case. I can then
flick the switch back into the 'on' state and it stays off.

I don't even know if it is a hardware or software problem. Maybe I need to
uninstall the latest WinXp update.

Any ideas on what I can do to fix this problem?

Right click on "My Computer", select "Properties", click on the "Advanced"
tab, click on "Settings" under "Start up and Recovery", clear the
"Automatically restart" box, click OK, then back out. Restart your machine
and then try to shut it down, you should get an error message that will help
you determine what the problem is.

First step would be to turn off automatic restart on error. Right click My
Computer | Properties | Advanced Tab | Startup and Recovery - Settings.
Under System failure untic Automatically restart. Ok out. Now on a restart
it might go to a blue screen with an error message. If so copy that down
verbatim, then start your research here:

Ben,

There is a registry key that you can set to totally powerdown the machine

To get into the registry:

Click START
Click RUN
Type 'regedit' (without quotes) & press OK
Expand the '+' signs until you get to the 'WinLogon' key where you click on
it
In the right pane, double-click the 'PowerdownAfterShutdown', type 1 & click
OK

It is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Key name: 'PowerdownAfterShutdown' (STRING)

Set it to '1' (one)

Try that

I hope this helps,

Thaks Newbie and everyone else for your inputs. I will be able to get
straight onto the problem when I get home from work!!

I went through the steps and unchecked the "Automatically Restart" but it
hasn't made any difference. I didn't get the error message after restarting
and on shutting down it still boots back up straight away. What else can I
do?

Did it ever work ok? If so what changes were made to the system between the
time it worked and now? What about a shutdown from safe mode?

Go into your BIOS and, under Power Management, disable all the entries like PME
event wake up, USB Resume, Power on by alarm, etc.

If that works you can then turn them back on to see which one (ones) are causing
it.

It may be caused by a PCI device like your modem. Disabling the PM entries
usualy cures it.

Yep there's been no problem until recently. There has been no changes made
to the system... the only thing I can think of that might affect the system
is an update from Microsoft.

Just tried a shutdown in Safe Mode... it still reboots by itself.

And what was installed through windows update? Was there a driver update
included? If so rollback that driver using device manager.

Have you tried uninstalling the other updates that were added right before
this problem surfaced, and then a system restore to the restore point set
right before windows updates were installed?

 

[Ben]

Haven't tried that yet, will try it tonight when i get home from work. I'm
wondering though... could it be a hardware problem?! Like the power supply.

"And what was installed through windows update? ..." - I'm not sure how to
tell, I'll have to try out find what was updated.

Go to the windows update site and look in the update history to see what was
installed. Then research those updates. I think there is a chance it could
be hardware related. That hasn't been ruled out.

I am having exactly the same problem and don't know why. I hate to 'kill'
the computer to turn it off by depressing the power on/off button, but it's
the only way I can actually turn the computer off, other than unplugging in
from the elec. supply. I sure could use some help here. I tried right
click on my computer > properties > advanced > system restart > uncheck. It
didn't fix the problem. In other advice online Googling for an answer, it
was suggested that it could be the result of a driver problem with a CD/DVD
burner installation. I checked the maker of the CD/DVD burner for a framwork
update - none applied.
