I recently wanted to start a new game on fallout 3 goty edition but the game wouldn't even go to character creation: it just froze every time at the loading screen. I then erased every trace of a save file and began a new file.

That kinda worked until i got to the "one year later screen": it froze in white screen and just kept playing musicbox music until I shut it off after 30+ min.

After trying again and again I finally managed to create a character during the 9th or 10th try. I got out of the vault and everything until I got to Megaton. note: until here I made multiple save files just in case.

No matter how many times I entered the town or a building, talked to people(moya, lucas sims, burke,...) or watched my pip-boy; after 5 minutes the game would always freeze shut, no matter on what save file(again, I made a few different ones).

So I decided to stay away from megaton and explore the rest of the wasteland. No real problems until I came across a few new weapons:

Turns out each time(even on different save files) I want to take out a shotgun or the mesmetron and return from pip-boy menu to the game it freezes shut.

I shudder to think what other bugs may lie further on: but even as it is now gameplay becomes extremely limited and very frustrating. Is there any way I can have less bugs? I'll download/buy any patch, I'll clean the memory of my Ps3/ buy a new one or buy a new game disc if it solves the problem and I can play the game normally.

Any ideas?
