Geometry shader = BSOD?

 So I am rendering some points and wanted to quickly visualize them as billboards.  The geometry shader is a good way to do this so I wrote a GS to output a screen aligned triangle where each point would be.  This works-- mostly, except when I randomly get a nice blue screen of death while looking at the output.

      I wonder if I'm stressing the GS too much somehow.  While I am only outputting 3 verts for each incoming vert, I am rendering millions of points.  I've tried a few different variations of the shader and they all seem to eventually BSOD on me.

   Hard boot restart each time it happens, grrrr.
