The problem is not with the Windows XP. It is the problem related with power supply of your computer including the power supply unit of your computer. Most probably, the problem is with the power supply unit of your computer. When you want to turn off your computer, it automatically starts due to bad power supply unit. You can change the previous power supply unit with a good one to confirm the case. You can also check if there is any bootable CD in your CD Drive. If found so, turn it out and try again to turn off your computer.

I hope you understand it.

Hello Mason,

To stop automatic restarts after turning off your computer, you have to take several steps:

1. First, you need to go to the Bios setup options.

2. In there, you can check the power management system.

3. If you see that everything is alright there, then you will have to install the operating system again.

With these steps, your computer will stop automatically restarting after being turned off.

After all of this if you are still having the same problem, then you will have to change your motherboard.

I hope that my suggestion will help you.

This problem of being automatically restarted after shutting down Microsoft Windows may be caused by different reasons. It could be due to a problem in a device in the CPU or it could be a problem in Microsoft Windows itself. With all the computers and BIOS I’ve checked, there is not a single one that offers an option in the BIOS that can instantly restart the computer.

And even if you incorrectly configured the BIOS, it will still not cause the computer to automatically restart. First, you need to check if the problem happens regularly or randomly. Start the computer normally and let Windows boot. Once it has completely booted, shut down Windows normally by clicking Start, Turn Off Computer, and finally selecting Turn Off.

See if the computer will turn off normally and will not restart. You can also do this by pressing on the power button on the CPU once. If the computer still restarts, try restarting using the Last Known Good Configuration setting. Restart your computer and press F8 continuously before the Windows logo appears.

When the menu appears, navigate and select “Last Known Good Configuration (your most recent settings that worked)” using the arrow keys. Press Enter twice to boot the computer using this setting. Once booted, shut down again and see what happens. If nothing changed, forcibly shut down the CPU by pressing and holding on the power button until it is turned off.

Once turned off, open the CPU case and disconnect the following devices: memory card, network adapter, sound card, and video card. If you have other devices attached on the PCI slot, remove it as well. Once the CPU is clear, attach devices as follows: first, connect the memory card and video card then start the computer.

Once booted, shut down normally then see if it restarts. If it shuts down normally, connect the sound card next then start it up again then follow the same routine. If it shuts down normally, connect the next device, the network adapter then start the computer again. Follow the same routine.

Once you encountered that the computer restarts again after connecting a particular device, that particular device is already faulty and needs replacement.
