Build Terrain Crashes PC

[Dan Park]

It sounds like the problem is related to the PC since it works on one and not the other.

I would look at the PC's memory, try a good memory checker. A bad sector of ram might cause this to happen during more intense calculations.

If you copied the plan it was crashing on over to the other computer it seems like it should crash there if it was corrupt.

Also if this happens only when creating 3D it could be related to the video card. Sometime lowering the render video quality in defaults can make a weak video card work. But as you stated it renders a complex structure with no difficulty.

When you stated the PC totall freezes, I take it to mean nothing works at all. This generally indicates a hardware problem.
