That would be a pure hardware error. For example a cosmic ray hitting a cell the DRAM and flipping a bit. Or maybe the Intel FP-Bug, could also be a computer error.

Anything else in software is a programming error, but not necessarily a programmer error, since it might start with wrong HW specs, compiler bugs, etc.

So "computer error" is when the hardware designer screws up and "human error" is when the software designer screws up? That seems pretty arbitrary.
