GA-Z77X-UD5H will not POST

Just assembled the machine in my profile.  When I plugged it in and powered it on, all the fans start, the main BIOS light come on, but then it powers itself down after about 1 sec.  It pauses for another sec or so and powers up again but only for 1-2 sec.  This repeats and repeats.

No LED code and no beep codes from the speaker.  I tried moving the memory around as well as changing the motherboard's battery.  Tried clearing CMOS and also booting from backup BIOS.

Any suggestions?  Note that I am trying to use the i7's on board video and do not have a video card in the machine.  Monitor is connected via the onboard DVI.

you may try different power supply or add a video card to check.
some power supply need more loading to boot up.

Hi

I would suggest that firstly you try clearing the CMOS by following these instructions.


Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.
