Turning off PC causes warm reboot

[Timoteo]

I just did a clean upgrade of my parents computer from Win98 to WinXP. Everything is working great exept when I turn off the PC (Start --> Turn off Computer), it just does a warm reboot. This means there is no good way to power down the PC.

I've tried the power management settings in the BIOS setup and nothing seems to apply.

My Specs are:

CPU: Athlon XP 2800
Motherboard: A7N8X-X
Bios Version: Rev 1011

Thanks in advance for any information.

Control Panel > System > Advanced > Startup and Recovery. Untick "Automatically restart" and set memory dump to None. Hopefully, you'll get a blue-screen error with a message next time. It may actually be crashing during shutdown.


Update the motherboard BIOS and then disable any "Wake On" events in BIOS setup.

BipolarBill,

Thanks for the reply. I followed your advice and it helped me to get a better understanding of the problem. The system now hangs during shut down.

I examined the error logs and found this error message:

Event Source: Userenv
Event Category: None
Event ID: 1517
Description:
Windows saved user ComputerName\UserName registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use. This is caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account. Event Type: Error

I did some research and found this info at Microsoft's website:

http://support.microsoft.com/kb/837115

I'm going to try the utility discussed in the article and see if it takes care of the problem.

Thanks BipolarBill for helping to see the problem as a software problem instead of a hardware problem.

Interesting link. I downloaded it and am now using it because I had those errors. Still, my PC shuts down OK anyway.

What I'd like to see is if you get blue-screen errors and what they are. Those errors are NOT logged in Event Viewer.

No blue-screen errors, the system just hangs. What I mean by hang is the system takes a long time to shut down windows. Then the monitor goes blank (I guess because there is no more video output), but the PC never turns off. The LEDs and the fans stay on?!?!

As soon as I install the utility, I'll let you know if it helped.

As I've suggested, update your BIOS.

....it is a great little utility for any system.

But if it doesn't fix your problem you may want to look for some device conflict as it shuts down - that' s been the usual culprit for me even though the error doesn't specifically say that. In one case the video card didn't like the IRQ the onboardsound was using and the sound at shutdown was causing the problem - moved the card to another slot and also freed up an IRQ in the BIOS by disabling the 2nd serial port.

In the other I - a long time ago - had the same problem every time I tried to shut down the comp w/o logging off the internet - fiigured it was the modem and jiggered the comp 'til the IRQ's were changed.

Can you tell us what devices are sharing what IRQ's - or after you install the utility tell us if you do (doubt you will because you appear to be losing your video too soon) get another error

and updating your BIOS may help if the latest revision gives you that info, and sometimes - go figure - even flashing the same bios over again has solved a problem or two - but only when I've just built a system and it's buggy

Let us know

[Timoteo]

I installed the User profile hive clean up and unfortunately it had no effect.

As I've suggested, update your BIOS.

I just updated the BIOS with the most recent one ASUS's website and the problem still persists.

Thanks guys for the help, this one really has me stumped.

Well, I finally figured out what the problem was. This link on Microsoft's website suggested shutting down while in safe mode:

http://support.microsoft.com/default...b;en-us;308029

When I did so, I received the following stop error:

*** STOP: 0x0000007E (0x0000005,0xF9E46DAB,0xF9E699B0,0XF9E696AC)

*** NV_agp.sys - Address F9E46DAB base at F9E46000, Datestamp 3d793e1

It seems windows was loading the file nv_agp.sys into memory eventhough they do not have an AGP video card.

My solution was to rename the file so it would load into memory. The system now shuts down without any problems.

Thanks everyone for your posts.
