Solution found: EZ Debug DRAM LED on new motherboard?
Current specifications have been adjusted. The motherboard is MSI MPG B550 Gaming Plus. RAM includes two 16GB modules operating at 3200MHz CL16 T.Force. The CPU features a 3800X and 5800X3D processor. The GPU is GTX 1070. Storage capacity is Samsung 970 Evo with 500GB. The BIOS has been updated to the latest version using M.FLASH. All components were removed during the update process. The motherboard was replaced entirely without any BIOS settings. Attempts to boot with the Ryzen 3800X were unsuccessful; the CPU Debug LED activated briefly before becoming stuck on the DRAM LED. Various RAM configurations were tested, including single sticks, dual sticks, and different slots. When attempting to boot with the Ryzen 5800X3D, the CPU Ez Debug LED triggered. The CPU cooler was installed on each test unit, yet overheating did not occur. Possible causes were considered, but I remained cautious during installation. Help would be greatly appreciated from anyone with experience. Thank you. Update 1: The issue was not the GPU; similar results occurred after clearing CMOS with an older GTX 1050. Memory was also ruled out after using a different stick and clearing CMOS once (3800x, 8GB Corsair Vengeance). However, the DRAM light remained active after rebooting. Keyboard RGB stayed on during successful boot. I will continue trying to reboot. Update 2: Initially thought memory was the problem, but testing confirmed it wasn’t. After further debugging and LED observations, it appears the T.Force memory triggers the CPU Debug light. Testing each RAM slot with different sticks consistently activated the 3200MHz LED, allowing use of an older 2400MHz stick. The current challenge is understanding why the T.Force memory causes this behavior.
Don't assume it's the Memory, I used an old stick I had, same problem. However, I managed to get it BIOS once after clearing CMOS on (3800x), using an 8GB Corsair Vengeance, but the DRAM light is still on after rebooting with the same setup. Keyboard RGB was active when it worked, and I'm planning to keep trying to reboot.

Appreciate all the support!
Just bought new RAM and it resolved the problem. I’m not sure what caused the old one to fail—maybe static or a shock from being grounded.
EZ Debug can mean different things, which I discovered.
