New mobo gigabyte 990fx, computer turns on then off then on again.

So long story short i installed new mobo, its been working flawlessness. The only wierd thing is that when i press the power button to turn on comp, it turns on for 2 seconds, then turns off for 2 seconds, Then turns on again and works properly. My mobo is gigabyte 990FXa-ud3. I have read in a few forums that some people are having same issue.
Its not my psu, i have a 700 watt.

    Rig:
    AMD fx 8350 4.4ghz OC
    gigabyte 990fxa-ud3
    EVGA gtx 670 FTW
    GTX 550 ti as dedicated psych x
    8 gb ram
    700 watt psu- AzzA. No one has heard of AzzA cause its a new company but from what i have read they make a solid PSU and desktop cases.

    And forgot to mention it never did this with my old motherboard but my old board was a 4+1 so it was not power hungry. ASROCk N68-VS3-FX

    I have no comp issues when its on. I have played BF3 and other games 4 to 5 hours straight and prime95 for 12 hours. This only occurs when I turn it on (cold start).

    hmm could be some sort of settings in the bios, have you tried updating your bios?
