Installing Fallout 3 on Hp Pavillion, Windows 7 64-bit

On the 29/06/2011 I got the 'Fallout 3 Game of the Year Edition' for PC. Running it on a 'Hp Pavilion dv6' with the applicable system requirements, as follows.

• Operating System: Windows 7 Home Premium 64-bit
• Processor: Intel(R) Core(TM) i3 CPU       M 350  @ 2.27GHz (4 CPUs), ~2.3GHz
• Memory: 4096MB RAM
• Card name: ATI Mobility Radeon HD 5470

The Solution

The nature of my the problem occurred after installation of Disk 1, when I started the game it crashed, after just moments of game play. I managed to get the game working and, special thanks to MissionAvoid and pocho951 from YouTube, the resolution goes as follows.

1. Make sure you are using appropriate resolution quality and try starting it windowed as opposed to full screen (if this resolves the problem this is Windows in error.). 
2.  Download d3d9.dll at http://www.mediafire.com/?am8daeaj1rmc7oe
3. Navigate to folder Fallout3. Drag and drop d3d9.dll into Fallout3 document.
4. Within the folder titled Fallout3 this will be a Fallout3.exe document open it
5. Locate the script that reads- bUseThreadedAI=0
6. Then change this into- bUseThreadedAI=1
7. Create a new line below the change you just made and paste in- iNumHWThreads=2 

I was also having trouble installing Disk 2, the installation wouldn't load I resolved this by installing whilst in Safe Mode.  Safe mode can be accessed by repeatedly tapping F8 before windows had loaded. You can do this when you turn your computer on or by restarting your system. However I am having trouble accessing the additional content from Disk 2.
