Hi, I've recently upgraded my system from 2x4GB DDR4 2400mhz Corsair 2x4 2400MHz CMK8GX4M2A2400C14 to be exact.
To 2x8GB DDR4 3000mhz Corsair

Again to be exact.
Since the system will turn on for about 5-10 seconds, and then turn off again. No beeps are made from the mobo at this time. And it will attempt to boot again if left alone.

I've tried refitting the heat sink and CPU, am now going to breadboard my way up to see if it can start at all.
Was wondering what the problem was
