Fernando was right on. Here is his response to me:

I ran the following statements on both machines which caused it to crash:
import numpy
numpy.test()
Here is the output:

Sounds like the problem is the fact that my desktop computers do not
support SSE2 instructions which are in the latest numpy binaries.
This also explains why it works fine on the laptop which does support
SSE2.
I piggy-backed onto an existing thread on the numpy list (is that bad
listserve etiquette? - probably: I now have the same question on two
lists and I tried to high jack a thread.). Unless someone has a
better idea, I will try and build from source for him. But my windows
building skills are not what they should be.....
