Installed the game on two PC's so me and the missus can play at the same time.

Here's what I've done, the same was done on both PC's

1. Installed Fallout and tested it was working.

2. Installed the UPDATED Unofficial Fallout 3 Patch and tested the game was working.

3. Installed FOSE, Darnified UI and CASM.

4. Ran BOSS to sort the load order.

Again, the same was done on both PC's. One is working 100% fine. The other seems to crash at infrequent periods. Completely random it seems.

In order to try and resolve the issue I have...

1. Checked the threaded settings in the ini and that they were correct, which they were.

2. Installed the stutter remover.

3. Added "d3d9.dll" file into the Fallout 3 directory.

4. Set "Fallout 3.exe" to run in compatibility with Windows XP SP3.

5. Disabled HDR vsync.

6. Disabled CASM.

I tested the game after each step and it still had the problem. This was last night however, started a new game on there now and knowing my luck it will work fine...

So any ideas what else can cause this?

Thanks in advance everyone
