Has anyone else been having issues with Fallout 3 after installing the DLC?
While playing Fallout 3 the game will freeze and go non-responsive after anything from 1 minute to 20 minutes.
Started a new game: still happened.
Uninstalled Fallout 3 and reinstalled and repatched: Still happens.
Intalled new Video Drivers (Nvidia 181.22) and new Soundcard drivers: Still happens.

System:
OS: Vista 64
CPU: Intel Q9650 Stock speed
Video Card: EVGA 8800GTS 512MB Stock Speed

Was not having any issues before install of DLC.

Any Ideas?
