I recently upgraded to Asus Z390 - A alongside i5-9600KF.

I removed my old mobo and cpu and reattached everything. However it does not boot up. It kept showing the yellow Q led light. I tried different configuration of the ram sticks, initially 2&4 to just 4 (changing between each stick) and does not work still.

I'm using Cosair Vengeance 2x 8gb 3200MHz sticks.

Specs:

2x 8gb Cosair Vengeance RAM
