I've just bought two more modules of RAM for my motherboard because I had two of 4GB DDR4 and I wanted to have 16GB so I bought two more modules and I found a problem installing them this evening. I want to use 4 slots to have 16GB so when I installed it a red light came up from the top of the motherboard ( I attach a photo of the motherboard:http://content.hwigroup.net/images/products_xl/320235/2/msi-b150-gaming-m3.jpg , where you can see on the top left side DRAM, CPU and VGA). The problem is that when I power it up the DRAM light comes up and it doesn't show anything on my display. I've tried to clear the CMOS but that didn't work either. Now, I've been trying storing the ram in different slots and the light has changed. Now a light comes from the DRAM led and then the led shuts down and comes up the VGA led with nothing showing on my display. I would appreciate any help to install this additional modules of RAM without these problems.
