Fallout 3 problems - no music in main menu, crash on starting new game

[Jimbo Mahoney]

I'd like to play Fallout 3 again, but for whatever reason, it no longer works.

I can load the game fine, but when I start a new game, it crashes almost immediately.

I can't remember the last time it worked.

Windows 7 64bit
Rig in sig, latest ATI drivers.
No fallout addons or expansions

Here is what else I've tried:

Verified game cache
Downloaded latest KLite code pack
Run window mode

Any ideas on what to try?
