I had this MB in my computer but was having problems with it freezing up, so I replaced it with the Shuttle AK31 which crashed on bios upgrade and I sent it back for replacement. Meanwhile I thought I would put the ECS back in, but it shuts down after 5 seconds. No it cannot be getting hot that quick, I even uplugged the power and left it overnight, still same thing early this morning. I have checked all the connections and cannot find anything wrong with any of them. My luck has been running bad lately. Just built the computer with the ECS and Athlon 1.4, had problems, went to the AK31, more problems, went back to ECS wont work at all. grrrrrr I can fix everyone else's computer just not my own.
