so I just got a new case and a 50w lower power supply then my old witch was 450w either one of the power supplies cause the computer to turn on then off after it turns on for a split second it shuts off and the power button does not respond when you push it I have to wait and then it will turn on and off by itself I have a 550w power supply coming in the mail soon all the stuff is hooked up right but I don't know what's wrong
