intel 4500 cpu
e-gforce 8400gs vgA
650watt cooler master
and 2 80gig hdd not connected
All just put togethor. Not a mobo problem I suspect since I just exchanged this one for one that I recently bought that was bad at microcenter. Everything is new except for the harddrives. Everthing else works on another mobo. But it just won't start. Sometimes it starts up for like 3 secs. then powers off. Fans roll lights come up then powers down. I can't see the things I have needing more power, but I could be wrong. Please don't offer read the manual answers, because I've already done that. I put the whole thing togethor and it worked before on the other motherboard there was just a bad controller on it.
So my question is... why does it only come on part of the time and then only for a couple of secs. then power down. Could it be that the connections are wrong for the case front panel.
Oh one more thing. When it does start up it's not because I've pushed the power button on the case. It just comes on when I switch the power on for the pwr supply????
