System won't power up

[Viper0329]

P4 2.53
ASUS P4533-E
Enermax Whisper 330

I just put this system together, and my power button doesn't seem to work.

I have to switch on the PSU from the switch, then push the power button. The system turns on and boots fine. Once the system is shutdown, however, if the power button is pushed, it won't boot. I must turn off the PSU from the back, turn it back on, and it will turn on from the power switch.

I ruled out the switch by trying my reset button. Could this be signs of a bad mobo that I need to RMA?

I know it sounds simple but I have done this myself....Have you tried flipping the MB connector around? And triple checking that you have all the front end buttons and LEDS on right......I have had those on backwards or one pin off before and it would cause funny things like that.....

I agree...check ....double-check all case wiring hookup to the motherboard....

I did, and I still get the same problem

I think the power supply could be the issue....330?? I usually see 350watt psu and such...

Have you ran system with the most minimum devices installed?? Try it...
