1. Determine if new hardware is causing the problem. If you've recently installed any new hardware, such as additional RAM, a new video card or a new hard drive, remove it or replace it with a different piece of hardware and see if the problem occurs again. If it does, then the problem is not in the new hardware. If it does not, then the problem is most likely with that piece of hardware.
2. 'Roll back' the computer to the last known good configuration to fix driver-related errors. Restart the computer and press the 'F8' key as the computer boots up. Once the Windows boot screen appears, choose the 'Last known good configuration' option and press 'Enter.' This procedure will attempt to start the computer in the state in which it was last working properly. You can also try choosing the 'Safe Mode' option to boot the computer and remove the faulty driver software or any other type of software that may be causing the page fault error.

3. Perform an operating system repair operation. This operation will replace all of your core Windows files on your computer but leave your data intact. Insert your Windows XP CD into the computer and boot the computer from the CD. Once the Windows setup screen appears, choose the option to install Windows, press the 'F8' key to agree to the license terms, select the version of Windows XP you want to install and then press the 'R' key. This will launch the automated repair installation process, which can take 30 or more minutes to complete. Once the process is completed, sign back into Windows and see if the page fault error is gone.
