So randomly one morning my PC decided to not boot, the DRAM debug light was on so I decided to re-seat the RAM. The same thing kept happening so I tried booting with 1 stick only and it worked, the problem now was I only had 1x8gb in my PC with me being a gamer I use over 8gb. So I decided try and troubleshoot by myself, I came to the conclusion that BOTH sticks work by themselves but when they're both inserted my PC decides to not boot? Why would that be?
I have my RAM located at A2 and B2 normally which are the recommend slots.
PSU is 1 year old
CPU: Ryzen 7 2700x
Motherboard: MSI b450 mortar titanium
Ram: G.Skill Trident Z @3200mhz c16
SSD/HDD: Samsung 970evo m.2 500gb
GPU: Asus AMD Vega 64
PSU: Gigabyte GP-G750H 750w 80+ gold
Chassis:NZXT h410
OS: Windows 10 pro 64 bit

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Also, which slots have you populated your rams on? Latest BIOS for your motherboard? Include the age of the PSU as well.

Did you try all slots? 1-3/2-4? and switched the RAM sticks into both? could potentially be dead slots, or even disabled in your BIOS, these are just light guesses though but its always good to check :)

Thank you, I updated my comment with all my specs. As for the bios I'm not entirely sure if its the latest? But it was when I first build the PC.

Yes, I did try all the slots, I was thinking it could be dead slots but I wasn't entirely sure....
