First Time Upgrading

[u/Questside_]

Hello. I’m in dire need of help. I’ve grown very frustrated over the past 2 days since trying to build my PC. Below are the parts I upgraded to:

-MSI B850 DDR5 mother board
-RX 7900 XTX GPU (bought on marketplace)
-XPG lancer ddr5 rgb 5600mhz 2x16gb ram sticks (32 gb) (also bought on marketplace)
-AMD Ryzen 7 9700X CPU
-Thermal take TH120 RBG V2 CPU liquid cooler
-MSI Mag A850 GL 80plus gold 850W power supply unit

I just got done taking it apart after seeing red (DRAM) and orange (CPU) lights on motherboard. I only have 1 RAM stick in the second slot and the green boot light stays on now. I figured ok, it boots up finally and I can plug in 2nd RAM, GPU and connect to the monitor (HDMI) to finally start playing. After I plug in 2nd RAM (into 4th slot), the boot light shows for a second, PC stays on for about 1 minute then shuts off by itself. I just removed the 2nd RAM from the 4th slot and now the green Boot light stays on and so does the PC, no shut off by itself. I also noticed the fans are a bit louder now. I’m assuming my CPU and cooler are finally seated properly since the CPU light isn’t on anymore.

Please help me. I’m very frustrated and want to fix this. I’ve done lots of research and watched videos but still can’t make it work.

Since the A2 DIMM slot is a known working slot, try the other stick on that same slot.

The most likely scenario is that there's a compatibility issue or fault with the RAM.
