    Do you have the AUX 12Volt CPU connector from the power supply connected to the motherboard?

    Try this and Wait

    Use the Cmos clear jumper and with the computer off, use a screw driver to touch the ends for 8 seconds at least. Then press the power and wait 30 seconds and it should start. This is a temporary fix. You will have to do this every time you cold start the machine. I still have the same problem and will be looking for help. For now this is how you can enter bios or windows. Thanks.

    Its not much of the boards problem and i think asus is great.

    Its sapphire cards. I have a sapphire 5770 and its doing the exact thing. It won't boot. But if i get a xfx or a asus 5770 card it will work. Its a compatibility issue with sapphire cards. I don't prefer them anymore. Sapphire won't work with all motherboards for some reason.
