I am no expert by a long shot but is the fan running in safe mode is it overheating and shutting down?

try and repair the Operating system of your computer it will solve your problem or you can check all the running processes in the task manager must of time it do cause the system to slow.

Computer doesn’t power down when users shut down
In some cases, Windows XP’s Setup program can misidentify the power management scheme in a computer’s BIOS as Advanced Power Management (APM) instead of Advanced Configuration Power Interface (ACPI). When this happens, users will notice that the computer no longer automatically powers down when they shut down Windows XP. Instead, they’ll see the message It Is Now Safe To Turn Off Your Computer and be forced to manually press the power button to turn off the computer.

You can verify this problem by checking the power management configuration in two places—Device Manager and the Control Panel. To quickly access Device Manager, select Start | Run, type Devmgmt.msc in the Open text box, and click OK. When you see the Device Manager window, locate and open the System Devices item. If Setup identified the system as having an APM-compliant BIOS, it will be listed as a Standard PC in the System Devices tree. (If it were identified as having an ACPI-compliant BIOS, you would see it listed here as a Microsoft ACPI-Compliant System.)

To check the power management configuration in the Control Panel, open the Control Panel from the Start menu. If the system is using Category View, select Performance And Maintenance and then click the Power Options icon. If the system is using Classic View, just click the Power Options icon. If Setup identified the system as having an APM-compliant BIOS, you’ll see an APM tab in the Power Options Properties dialog box. (If the system were identified as having an ACPI-compliant BIOS, you wouldn’t see an APM tab.)

You may be able to fix this problem with a BIOS update. To begin, check with the computer manufacturer’s Web site to see if it’s providing the latest BIOS update. If you’re troubleshooting an off-brand computer, you may be on your own as far as tracking down the BIOS update. Here’s how.

Once you obtain and install the BIOS update according to the manufacturer’s instructions, you must perform what I call a Refresh Installation, in which you reinstall Windows XP on top of an existing Windows XP installation. You must perform this reinstall operation because the power management features are tied to a special power management Hardware Abstraction Layer (HAL). During the Refresh Installation procedure, Setup will completely redetect all installed hardware, including the updated BIOS, and rebuild the power management HAL as well as the part of the registry in which information about the installed hardware is stored.

problem is really amazing.......hmmm i think its auto start by your bios.... just see is there any option in the startup option for your bios

2000 Is Windows 2000. Why did you put that disk in? Did you start loading Windows 2000 or XP Pro, XP-Home?

It sounds like your switch is wired to the reset jumper on the motherboard or you are hitting reset.

Tell me what the computer screen has on it before it shuts down please.
I will wait on you answer. Do not rate until we are done.

You should be able to change this setting in the PC bios menu. Windows XP should interact with this and change it automatically, but it occasionally doesn't. If you have trouble finding the appropriate menu and changing it, please post back with details of your PC (ideally motherboard make and model) and we can hopefully talk you through it. When the computer starts up, there should be a screen before the windows XP screen which says something like "press f8 to enter BIOS setup", but all machines are a little different. If you can get into the BIOS setup, only change things which you are sure you know what they will do, or you can cause all sorts of problems. Hope this helps, post back with system details if you need more :)
