What MajorBoris said.
And reading through all this, what processor do you have?
In one post I read Phenom II x6?
If it is a quadcore right out of the box pressintg that core unlocker should not have been necessary and all four cores should have been detected.
And get yourself a case with proper connections for power and reset and so on, seriously, doesn't have to be anything expensive, my first case was $40.00. Just get rid of that HP thingamadingdong.
And you wrote the psu is new and 680 watts, it would be helpful to know the brand name, especially if you have enough amps on the 12 volt rail to properly support your video card.
I know all the things people wrote here are a lot to sift through, but if you spent all that money on new components it is very well worth it. However I would definitely start with a "normal" connection to the power button and after that cecking the specs of your psu, while making sure, as you certainly have, that all components are properly seated.
After that I would check the bios version and then check on Asus' website if your processor is in the supported list for your mobo and what bios version is the earliest that supports that processor. On the motherboard support cd you should find a utility called AsusUpdate, you can use that to update the bios easily under windows environment as well as verify your current bios version, easy peasy.
Good luck and let us know if you are faring better with your new build.
