Fallout 3 Problems, please help?

May be...

I'm on the main quest in fallout 3, i'm on project purity, i've done all the little tasks for my dad, [spoiler] my dad just sacrificed himself, and when i go through the door to follow dr. Li it always freezes on the black loading screen.



i've heard this is somewhat common, but all i've heard is "reload a previous save" or "your ps3 is overheating"



neither of those work, here is what i've tried so far:

borrowing a different disk



moving all my save games to a flash drive and deleting the install and reinstalling



i do not have an hd tv



i have tried unplugging my ethernet cable (internet connection) while playing



nothing works, please help.

thanks

If you have another saved game close to the progress you have now try playing that save and getting to where you are now, it may just be that your current save file is corrupt, always create seperate saves !!! :) Hope that helps.

your on own kiddo
