Last question: Trying to install Windows XP SP3 always fails. Any idea why this could be?
Try disabling your protections programs like Anti-virus, firewall etc.
In case this doesn't work, after you download the installer for SP3, unistall those programs, stay off internet while updating, and install them later.
