MY FALLOUT 3 KEEPS ON CRASHING. I'VE DONE ALL SORTS OF THINGS FROM EDITING THE .INI FILE,d3d9,INSTALLING MODS,COMPATIBILITIES TO EVEN NET.FRAMEWORK. PLS HALP

Please run dxdiag.exe and post the full report in spoilers

Have you followed the guidelines in the sticky. http://www.gamesas.com/topic/1465357-installing-fallout-3-with-windows-78-and-xp/

i have. the dxdiag still didn't help anything

I am having the same problem. I downloaded and installed from Steam. I used the guidelines for fixing it. The game continues to crash when I try to start a new game. I would post my DxDiag but trying to do so keeps throwing me out of the forum.

Still post the dxdiag report that gives us information on your system if it is capable of playing the game. I have a feeling you are only using an Intel Card and FO3 is not compatible with Intel Cards.

I figured that out after doing what I should have done in the first place: read all of the threads in the forum.
