Check your cpu heatsink to be sure it's level and all clips are engaged. Also check for loose screws or other metal under the board or in the backplate area.

Is this some kind of master control power center or something and not the power button on the case?
ok, it tunrs out the speaker connection from the front panel was causing a problem. When I disconnected it every thing works fine.... Thanks for your help.
