Building a new computer i just got my motherbaord today its an MSI k7n2 nvidia chip nforce 2 chipset.power is plugged into the board i have the power swwitch and led connectors all connected to the board when i hit the power button power flickers on for a half second and nothing happens. no power at all. i connected the power switch and led and reset connectors from another comp to that board and it did the same thing. is there something that im missing. that is not set up on the board. everything is connected power wise.
