I'm trying to troubleshoot a system with an Intel Core i9 12th Gen CPU, an RTX 3060 OC, 32GB of RAM installed as two sticks, and a 650W power supply. I've already cleared the CMOS, tested each RAM stick individually, reseated the memory, and tried starting the system by shorting the power pins with a screwdriver. When I turn it on, the motherboard's debug LEDs cycle from DRAM (orange) to CPU (red) and repeat. After roughly 10 seconds, it stays on the DRAM light and never reaches the boot screen. Could the memory be faulty, or are the CPU or motherboard also likely causes? Is there anything else I should check before buying a replacement 32GB kit?

Before replacing the RAM, work through a proper motherboard diagnostic sequence: test one stick in the recommended slot, try the other stick, confirm the memory type matches the board, and inspect the CPU socket for bent pins. Also verify that every required motherboard power connector is attached.
