1. Remove the Windows XP CD from the CD case or your computer. Look at the underside of the disk. Analyze whether it is scratched or dirty. Wipe it with a clean lint-free cloth. Use a CD repair kit if the disk is scratched. Scratches are the primary reason for installation errors. Look again at the CD, and if you see large scratches you may have to simply replace the Windows XP installation CD.
2. Disable any antivirus program you may have running on the system if you are installing an upgrade. Antivirus programs conflict with Windows XP setup and can cause installation errors.

3. If the installation freezes, stops or turns into a black screen, turn off the computer and wait 30 minutes for it to cool down. Windows XP uses a lot of computer resources, so trying to install over and over again can cause more computer errors. Restart the computer and the installation process again.
4. Check for connected external hardware or internal conflicting hardware in the case of a desktop. Remove connections to external devices like printers, memory sticks and external hard drives to prevent them from interfering with the system installation. Restart the computer and simultaneously hold the 'F6' key and then press the 'F7' Key. This will disable any internal conflicting hardware.
5. Note when the installation has a problem and stops. Notice whether the setup goes further on the second or third attempt before it stopped. If this happens, restart the computer and retry the installation after it freezes. Continue doing this until the system installs.
6. Write the error code that appears and search for it in the Microsoft Help and Support database (See Resources). Some error codes will specify which hardware or software they apply to.
