lion: did u connect the power properly? ,
my guess is that your atx aint cutting the on power when u start it , when u press the ON button it should just give power for a little sec and then cut it.
also not that u need 2 switches normally,
(1 main on/off (on psu) and 1 normal on/off switch ...)
you could always just take a screwdriver and tap the pins(2 pins) (just tap 1 time , short circuit em)on the motherboard to get it running (o see if its the prob) , i need to check my mobo to tell you where tough, hopefully someone else can tell u as i will be away for 2 days now..
anyway u must have this fuction working (the button]/pins connected with a proper connector)
cheers
