Windows 2000 Shutdown problems

Many possible causes. One of the easiest to start with is to assure that the proper drivers are installed -- particularly the vido/graphics drivers. If you've installed an aftermarket graphics adapter, go to #2 below, If you have the OEM graphics adapter in use, follow #1.
1)Go to the PC mancufacturer's site -- i.e. Dell, Compaq, etc. -- and look for updates to the drivers for the particular Model + OS combination. If the curent drivers are not up to date ( there are usually frequent updates ) install the new driver and retry.
2)If you are unable to follow #1, then go to the graphics adapter manufacturer's site (i.e. ATI, NVida, etc. ) and look for drivers there. Find the proper adapter+OS driver and install and retry.
This "fix" has worked on about 60% of the shutdown problems I've encountered -- especially when it has been on a relatively new machine or OS install.

Look at Technet article Q266169

Check in The hardware device if there some device that not properly installed try to reinstalled it or your video settings use
optimal.or much better to reinstall the windows2000

Maybe the reason is in using windows 2000 there is standard.Maybe your computer is not compliant Advanced Configuration and Power Interface(ACPI)BIOS,BIOS is the sofware interface that allows the windows2000 operating system to communicate w/your computer underlying hardware.

Windows strikes again,

Disable the IRQ steering in the device manager.
Go into device manager, system devices, PCI bus and IRQ steering, remove the tick from IRQ steering.
