Hi all just wanted to share my experience with Fallout 3. I used to have CTDs every 3 mins in the Wasteland since buying the game 2 weeks ago. What solved the problem was 1. the latest patch and 2. update of Intel motherboard BIOS. Between the two, I think it was the motherboard BIOS update that completely eliminated the CTDs. I haven't experienced a single crash since then. Hope this helps.
