What should I do with this memory issue?

[Citrusflavour01]

So recently I bought two brand new 16GB memory modules 3200mhz and the issue at hand is that I can't boot my Laptop with both installed at the same time. I can leave in one of my old 8GB memory modules and it will work with either of the new 16GB ones. At first when I had this issue I thought my Laptop had only 2 memory slots but today I found out that I actually have 4 of them and the reason why I didn't notice is because the slots are in the same area and it looked like only 2 fit. I'm a noob so let's leave it as that. Now knowing that I have two more slots possibly expands my option I would imagine? 

 

I should note that according to my Laptop's manufacture, I can only have 32GB of RAM at once so using any more than that will either just won't work or just make my Laptop not work that well. Every time I install both of the 16GB memory modules my Laptop won't boot and I don't have access to the BIOS. I can boot with one of my 8GB memory modules as I mentioned above ^. Is there anything I can do to sort this problem out? 

 

I would also like to provide my opinion regarding the speed of the memory modules. The new 16GB modules have a speed of 3200mhz and my old 8GB modules have 2400mhz. It might be a problem with the speed when booting the Laptop. I used the PowerShell to confirm that both memory modules are running at 2400mhz.

 

New RAM - 16GB DDR4-3200

old RAM - 8GB DDR4-2400
