Crash on build

Just starting to learn UE4, coming from a blender background. I create a new blank scene, just the chairs, and add a point lamp, and try to build it. It gets to 38% and then crashes entirely.

Win 7 Pro, i5 quad, 16 GB RAM, GTX 780. The GTX Is not being used for display, reason being when I use it to render with in blender, I want my display to be responsive. Do I need to go into my BIOS and set my GTX for display? Is this a memory issue, display driver?

That could be the issue. I would see if you can get it to crash consistently, if so then try setting the GTX as your primary card and see what happens.

That worked.

I went into the BIOS and switched my GPU to be my display, rebooted and I was able to build everything. Thanks.
