I am wondering if anyone has had this problem, or knows how to fix it. I was playing Fallout 1, and had gotten all the way to the fourth floor of the Cathedral, and was fighting the enemies. I had already quicksaved mid-battle on this floor, but when I did it again, my computer made the sound that it makes when there is an error (kind of sounds like a terrible representation of a gong), and then froze. After a few seconds, it said that Fallout had an error, and needed to be closed
So I went back on, reloaded my game, tried quicksaving, and the same thing happened. I then restarted my computer, and tried playing again. This time I didn't quicksave, but it still had the same problem. I tried this a few times, and it always has the problem around 30 seconds after loading. This seems to be specific to the Cathedral, because I tried making a new game, and it was running completely fine. So, does anyone know what's going on? I had already asked tech. support, but I am an impatient SOB and couldn't stand the wait of a half a day I am getting.
If it helps, I'm on Vista.

couple of things, check your compatibility mode and also see if you're running as administrator.
Basic things to always check.

I have no idea how to check my compatibility mode... or what that means (shutup!), and if I run as Administrator, all the save spaces are blank, so I wouldn't be able to load it to check if it runs.
And I just found out, it actually freezes a few seconds after an action. I tried just standing around for a few minutes and it did fine, I fired a shot and it did fine, but immediately when I end my turn by pressing space, it freezes. It also freezes whenever I press F6 or Esc. It might freeze other times, but that's all I know for sure.

to check your compatibility you can right click the icon and go to properties, and in there somewhere should be an option to change it. I'm not exactly certain right now as I'm on my windows XP laptop.
The reason why you don't see your saves when you run as administrator is because by default the user account cannot modify files in program files w/o administrative privileges, so under your user account files, you should see a temporary program files with your fallout saves in them.
you can then copy those into your directory under program files..
I found this walk through here
This might help your issue.
In Vista, when an old application without admin priviledges tries to write to a folder that it doesn't have permission for (like Program Files) then UAC, in order to allow the program to work, redirects the file to a special folder in your personal directory.
Check C:Users/username/AppData/Local/VirtualStore/Program Files

Well, C:Users/username/AppData/Local/VirtualStore/Program Files doesn't exist on my computer, but I did find the GOG folder with Fallout in it on my program files. And now I'm still lost. I don't know what I should be looking for, where I should be putting it, etc.

well copy/pasting that address may not work exactly, because where it says 'username' it's the username you created when you first ran windows vista, or you know whichever one you logged in under. and it's more like c:/

I know that. I just copied and pasted the other person's thing because I didn't want to type all of that. I also didn't want to give my user name... not really sure why

Just a note if you're still having problems. The game has always had ramdom crashes it you save during combat. Just NEVER save during a combat sequence and you'll probably have no problems with either Fallout 1 or 2.

Really?! Damn, I wish I knew this before I went this far. Well, I guess I can always just start over and make sure not to save mid-battle this time.

I finally got my game to load when running as Administrator. It still crashes. Whoopee.
