I got a new hdd recently so I had to reinstall my windows 7 64-bit onto it. Anyway when my fallout 3 reinstalled for some reason that game crashes as soon as I launch it. The game worked before on my other hdd. I need help. If anyone has a fix that may work please reply!!!!

You have to edit your Fallout.ini and find a line 'bUseThreadedAI=0' and change it to 'bUseThreadedAI=1' and then below this add a line 'iNumHWThreads=2's

Or in the taskmgr, make it only use one core

Or try running it in different compatibility modes

I'm having the same problem - tried all of the above fixes. It only starts to crash on program start after applying the v1.7 patch. Have been google searching and trolling forum for a full day trying various suggestions and uninstalling and reinstalling when they don't work. Anyone have any new ideas?
