Please Help, It Crashes While Playing the Game, randomly.

Sounds like a memory issue if it's randomly crashing... Could also be the
graphics card. Try updating the drivers. If you're already using the newest
drivers, check their website and make sure theres no issues with the card
you're using. Either way, you're better off asking them what's causing the
problem.

On mine the screen freezes, mostly it happens on specific maps.

Fallout 3 won’t work at all for some reason!
On the launcher screen when I click play, the game will attempt to load. It’s a black screen with the hour glass cursor in the middle. Then the game crashes to my desktop and the error message says “An error has been encountered and the program needs to shut down.” I have tried so many different solutions but non have worked.
Is anyone having the same problem or know how to fix?
What the hell is going on! I haven’t even got to see the introduction of the game.
Please help!

none u mentioned above is running.
