I initially had these problems when I installed and uninstalled the game several times over the last few days. But it would actually freeze in the opening cut-scene as the mother was giving birth, a little before, or a little after. When it froze, however, it would completely lock up my PC and I would have to pull a CTRL-ALT-DEL and close Fallout 3 in the task manager. I have tried running this in Vista Compatibility mode (Service Pack 2) as well as installing patch 1.7.A very odd thing happened when I installed the patch: The game would start by itself while the patch was installing. Weird, I know. I called Tech support and was told that they cannot guarantee that they can get the game working in Win7, and I told them that I would try applying thr patch and see if that helps before calling back, which I will do tomorrow if I cannot get this solved.
I also am pretty certain I upgraded upgraded to the latest version of DirectX 9 even though I already have DirectX 11 installed. If I remember correctly, I had to do this to get another older game working.
Anyway, since doing all of those things, I have been able to get past the introductory cut-scene and into the point where your character is at her/his 10 year old birthday party. Then again, I may have gotten locky, because I had to keep reloading my saves with "Continue" and praying I couldd get past the next checkpoint before another crash freezes everything up. The farthest I have beemn able to get is where her Dad gives her a BB Gun and she shoots a giant roach, but "Continue" only seems to keep brining me back to the beginning of this annoying birthday party.
Any suggestions from you Fallout Guru's?
