ASUS A7N8X-E deluxe power button problem?

[Pcmod]

I just installed a ASUS A7N8X-E deluxe on a mostly new system and . . .

Ok, my power button doesn't work whenever I shut down the the computer, no boot, no power, not post. The only way to correct this is to unplug the computer for a few seconds, and then it all works fine again, I just installed it after formatting my hard drive. Even if I shut it down during post with the power button it refuses to boot without unpluging then plugging it back in and then hitting the power button. I say it is one huge annoyance, i even tried messing with the power button cable with no success. I love the board, but it is a big annoyance, thanks for the help.

i would have to say that there is something wrong with the psu and not with the motherboard or power switch.

also try double checking this problem is the power supply section.

Thanks, but I never had this problem before with the power supply with the old motherboard a SOYO, K7V?? dragon, and only started happening when the new mobo was installed but I will try installing a different PS, i have a few laying around.

Check to see if there is a good connection to your motherboard. Try shorting the power pins on the motherboard with a screw driver that has a shiny, good conductive tip. If the problem persists, just fiddle. That's what I always do.

you can try to get a voltmeter and see if everything is receiving the correct amount of power from the powersupply.

im guessing that the motherboard is not getting enough power to start.

Well, rule out things one at a time:
1) Power Switch - use the screwdriver trick described above and see if it turns on, if so your switch is bad.

2) Power Supply - easy, just try a different one set up the exact same.

3) Motherboard - this is the least likely of the 3, due to how simple the turn-on function is - you can fry a board and it'll still turn on and do nothing.

Check all your connections VERY well - the way that this works is:
1) You hit the power switch which shorts those two pins
2) The motherboard shorts two pins on the ATX connector (big one) turning the Power Supply on.
3) Computer starts up.
