When I push the power button on my case the system starts for a only a second and shuts off. I switch the power supply button to off and turn it back to the on position and wait for about 10 seconds and it starts up fine. After being on I have restarted and it's ok. Could my cable hookup be a cause? I have a E660 Core 2, Asus P5H DH DL, Corsair XMS 2(2gb), WD 74 gb raptor, ATI x1900xt, Antec Nine Hundred case with Antec 550 watt Ne.
