Well I kinda consider you lucky, when I was going through my 12th time playing Fable II, I couldn't load the Spire, but instead of freezing, my whole console would shut off with three red lights, once I installed the game via HDD everything was fixed and was able to continue onwards.

As for an answer at this point, I would check your disk for scratches or smudges, I had my disc perfectly clean until about 2 weeks ago, then it had 3 light scratches and 2 smudges.

After taking a cloth to it, it's a bit better now.
