Power button will not turn on computer but MB will HELP!!

[pcurtj1974]

Power button will not turn on computer HELP!! I just put together a FX8520 with an ASUS M% A97 R2.0 and I remember something about possibly selecting the power button to turn off the computer. Now the only way to start it is to manually push some buttons on the MB and then push the power button for 3 seconds, then one push and it boots. Can someone tell me what is going on? I am running Windows 7 with a Corsair AX 750, 1TB, 4gig RAM, and HD5850. I already made sure all connections are okay.

Thanks

Correction, M5 A97 R2.0

Are you sure the front header connections are all correct ? ?
Even polarity reversal will cause this symptom.

[pcurtj1974]

Yes, positive.

Then it's possible the case switch is defective...

It worked fine until I finished installing Windows 7

Also, if I push the RAM ok button and the reset
 MB button the computer will boot with the power button.

Stop re-setting the MBoard...your stuck in a power loop it sounds like.

Installing a new OS would not affect the power switches if they worked before...

Basically, it will not turn on unless I clear the CMOS. I tested the PS and all the specs are fine. I do not get it.

Yes but nothing major. Tried a few alterations but reloaded the defaults

It also works fine on a re-boot, just not on a shut-down....

If it's that new i'd have returned it already for replacement...
