Hogwarts 3D Model

Hi , thank you for the model , but , Im having a great deal of difficulty , My machine is a AMD quad 64 (A6) with 8 GB , Nvidia Geforce 610 with 2 GB and Im using Blender 2.76 . When i imported the 3ds the objects were in some disarray , in paint mode most objects were covered with the texture for roof tops , then , when i attempted to texture paint and just touched any object with the brush it raised my physical memory use to 99% with cpu around 75% , i lost all control , security warnings showed and I had to shut down . however id still like to try and break it up into smaller projects and see what I can do , seems daunting but i need a suitable place for my new zelda shield . anyway , yea i know its not a state of the art machine . thank you very much . Ill keep trying !
