Try installing the RAM on the DIMM closer to the processor and restart the system if the problem persist try on each of the DIMMs or with different RAM.
Double check that your CPU's heatsink/fan is connected properly
Make sure you PSU is connected properly with both the main and aux power connectors firmly attached to the mobo.
Make sure the motherboard is not being shorting out by any other component or the surface.
If the problem persists I suggest contacting http://www.intel.com/content/www/us/en/support/contact-support.html technical support to get a replacement for the motherboard.
You will need to submit a web ticket at the following link in order to get a replacement.
