Here are a couple of guides designed to address the task of wiping the system clean and performing a fresh install of Windows XP.
It's something we all face from time to time, and it can be a daunting task. There are plenty of guides already available, but often they 'leave bits out', or else fail to explain things in straightforward terms.
The following are a couple of 'How To' guides I've written up to address the situation.
"How do I prepare to install the OS?"
"How do I wipe the disk and install XP?"
By the way, if that Windows XP installation you have was an 'Upgrade' from an old Windows 98 install, you are possibly the best candidate for the job, because I'd be guessing you're still having problems, eh?
Edit: Could people with questions they want answered after following the procedures mentioned, or issues and problems which arise, please post their questions to a new topic in the appropriate forum section? Questions asked here as a post will not be answered in this thread, as that is too 'messy' a way to deal with them. - Catweazle
