Direct3D

[tkgshow]

Can anyone help with Direct3D C++?
Why would a program that renders the top, bottom, front and back of a box using

    d3ddev->DrawIndexedPrimitive(D3DPT_TRIANGLELIST, 0, 0, 16, 0, ;

crash my PC when changed to render the complete box using

    d3ddev->DrawIndexedPrimitive(D3DPT_TRIANGLELIST, 0, 0, 24, 0, 12);
