If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows 2000 updates you might need.

If problem continue, disable or remove any newly installed hardware or software. Disable BIOS memory option such as caching or shadowing. Check your hard drive to make sure it is properly configured and terminated. If you need to use Safemode to remove or disable components, restart your computer pressF8 to select Advanced Startup Options, and then select Safe Mode.
