I ordered this machine because the one I was usung was crashing.  As it turns out my computer seemed to self correct on a limited basis so I continued to use it.  Eventually, I decided to install the new machine and after attaching all the cables, to my chagrin the computer wouldn't power on.  Took it to the tech and he thinkd the power station is defective.  My bad for not testing the machine immediately so just a warning to all.
