I havce 2 Asus barebones Terminator puters that are AMD platform. This is very similar to the machines I have http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=150931
Both machines will simply power off as if the power cord were removed from the supply. All the fans are operating correctly, and I can't trace the shutoff to a specific temp. I have run them with the case open with the same result. Often they like to do the first power off during a prcessor intensive action. After that, they will continue to just power off at random. They both have the same RAM, and I have swapped every part(processors, fans, RAM, cd drives) I can between the 2. One of them was even returned for a replacement for the same machine. All of them do the same thing.
Any troubleshooting suggestions?
