this is from John to me ,Steve,
If you think your software install is fine, then check the hardware. Seriously, programs such as Trainz will push the hardware to its limits and bring out any faults that other programs seem to glaze over. I have another program that will also bring the computer faults out. This too is very hardware intensive as it calculates mesh surfaces for landscapes and tree placement.
Memory problems are pernicious, and can be caused by numerous things and cause other problems such as corrupted data. I've had Trainz (older versions) die on my to the desktop randomly after a short time running, but other programs run fine. After much troubleshooting and hair pulling, which seems to hand-in-hand, I had Word croak on me after placing lots of images in it along with pages of text. (As usual this happened in the middle of a major school project that was due the next day!) As a last resort, after changing other components, like my power supply, I ran MemTest86. Immediately I had memory errors. A faulty DIMM was causing problems all along.
So keep this in mind not all software problems are software problems and can be caused by your hardware. I know you'll argue that this is a brand-spankin new machine, but this is usually when the most problems occur which is during the early lifespan of the hardware unless it was burned in.

thanks john, posibly the best advise of all for all having trouble
