Long story short, I fucked up Fallout 3 and I want to play it pretty badly so I put everything worth saving in a few USB drives and plan on reformatting my computer.
Now, do I do this? I don't want to do a system restore, I want a full-fledged reformat. I made a system repair disk but that basically makes your computer boot up to do a system restore. I have a CD with Windows XP SP3, but for some reason my computer refuses to boot from it.
