I had the same thing happen when my AMD-64 Desktop was brand new. It
would shut down completely at an unexpected moment. Sometimes
restarting, sometimes not. Nothing at all in the logs.
I insisted that the dealer replace the power supply and have never ever
had another problem of that sort. The only problems I DO have are
self-inflected. :) Ric
