So when I tell the boat guy to leave with me the game crashes loading The Hound Pits Pub, the game runs smoothe, I've turned off AA and running at 800 x 600, textures and model details are the only things up, my system:

HP Pavillion a1550e
GRFX: NVIDIA GeForce 8400 GS
CPU: AMD Athelon 64 X2 Dual Core
Ram: 1GB

Every now and again the game will CTD but once I tell the boat guy to leave, Freezes every time loading HPP

The game freezes, then a few secs later, blackscreen.
