The hard drive, motherboard, or some other critical component may be failing, or just the OS or hard drive corrupted. If you have files that you do not want to lose, you could try this... Pull the hard drive out, and use a "USB Hard Drive Adapter" (available fairly cheap online) to connect the hard drive to a friend's computer, and save all the personal files (documents, pictures, etc.) you can to a folder on the friend's computer or an external hard drive. That way, at least you may not lose your files.
Then, you could try to do a Factory Restore or Reload on the computer, and if that works, copy your personal files back to your newly restored computer. Good luck.

Windows 2000 is no longer supported. You need to be sure you have a recent backup of your files (documents, pictures, etc.), and plan on migrating to a newer machine.

I found these instructions for resetting the router to the defualt settings:
Use the "Backup Settings" tool to save the Broadband Router's current configuration to a file named "config.bin" on your PC. You can then use the "Restore Settings" tool to restore the saved configuration of the Broadband Router that you set before. Alternately, you can use the "Restore to Factory Defaults" tool to force the Broadband Router to perform reset and restore the original factory settings.
􀁺 Restore Factory Default
To restore the factory default settings of the Broadband Router, click on the "Restore" button.
􀁺 Backup Settings
Press the "Backup Settings" button to save the current setting in a filed "config.bin" or given filename.
􀁺 Restore Settings
To restore the backup file to the Broadband Router, enter the path and filename on the restore settings.
