Fixed.
My computer is fixed… It was just file corruption in a very bad place. The steps that were required to fix it are as follows.
1) Find a real XP CD, not one of those system restore disks Big Computer companies give you.
2) Boot from CD.
3) Wait 5 minutes whilst the CD loads all the drivers you don’t need. Then enter the recovery console.
4) Type CHKDSK
5) Type EXIT
6) Reboot.
7) All fixed.
