I recently bought a new motherboard (Z390 Auros Pro WiFi) after my old one kept showing a RAM fault light. After assembling everything with both of my RAM sticks, I'm stuck in a boot loop where the red light keeps switching between DRAM and CPU. I figured the RAM was the issue, so I bought two new sticks, but I'm still in the same situation. It only boots into BIOS with one stick, but adding the second stick sends it back into the boot loop. I'm really frustrated and considering returning everything for a console instead.

From what I'm seeing, it seems like the CPU could be the culprit. If the BIOS sees everything fine with just one stick in, it might mean something else is going wrong when you add the second stick.
It might actually be the CPU causing issues. That sounds like where the problem is leading, check for any signs of damage or make sure the CPU socket is clean and there are no bent pins.
Have you tried resetting the BIOS or reseating all the connections? Your Z390 has four slots, so make sure you’re using the right ones, ideally with a gap in between like 0-3 or 1-4.
Did you get the RAM sticks as a kit or buy them separately? That can sometimes make a difference.
Have you checked where you're placing the RAM sticks? You usually need to use one stick in each channel to get dual-channel functionality—check your motherboard manual for the right configuration. It's typically the first and third slots or the second and fourth. If that doesn't work, consider updating the BIOS.
