Why not provide details of the problems you are having with your PC/XP?

Perhaps someone may have the solution for you.

As for the Recovery Console read the thread further down as links on the recovery console are provided there.

To perform a clean install all you need to do is set your PC to boot from the CD Rom drive and boot with the XP CD and delete the partition followed by creating a new partition.
It will then let you format & setup XP on a clean HDD.

Make sure you back up all your files, emails, addressbook, favorites before you proceed.
