in that with all that power under the hood, it isn't strong enough to pull the train. I would have used one with at least 500Watts with all that new hardware. (Great choices BTW....)
Others may find other issues instead though so hang on for more responses.
I have just built my own computer (my third self built PC). I have done all the usual - install XP, install SP2, Anti-virus, media players etc.
The computer has been restarting (or powering off and on very quickly) a couple of times. Here are the times it has restarted 1. 3D Mark 05 - Half way through third test (later on I managed to complete the first two) and
2. End of an installation for a game demo.
It has also been crashing (i.e. quits the program/game and displays error reporting tool). I couldn't make much out of the error report except one time when it mentioned a DirectX 9 DLL file. It crashes during games, 3D Mark 05 and PC Mark 05 at similar points.
I have installed the latest DirectX 9 and ATI Drivers.
