Right, especially with a machine check exception, this is a hardware issue.
From what limited information I can see in the minidumps, the Intel CPU is throwing a NPX overflow exception.
According to the Intel documentation, within the Numeric Processor Extension (NPX), the actual instruction data isn't necessarily saved on the stack, so finding what caused this is going to be extremely difficult, if not impossible.
It looks like some kind of floating point arithmetic, passed from a coprocessor instruction, went kaput... Most likely a segmentation issue.
It's almost certainly your CPU at this point. If I was you, I would try to RMA it and go from there.
