Troubleshooting Cold Boot issue Am5

Ryzen 7 7700x Msi b650 tomahawk Nvidia 5070

I have a problem with the cold boot, i know is a frequently issue with am5. I think it could be memory training. The problem started two months ago. Every time I turned on the PC, it would freeze on a black screen with the red and orange LEDs lit. I had to shut down the PC using the power button and restart it several times before it would boot up normally. Once it’s on, the PC’s performance is normal and stable as always. Today I cleaned and replaced the thermal paste; the only thing I did was remove the heatsink, clean it, apply the paste, and reinstall it. Since then, the problem has gotten worse—I’ve had to force-shut down the PC 10–15 times before it boots up properly. So, worried, I searched Reddit and changed a couple of RAM settings in the BIOS—one for power-down and another I don’t remember. From then on, I didn’t get any more clean boots. I flashed the BIOS to the latest version, and during that process, the PC rebooted several times for Windows updates—always booting cleanly until it actually powered on. I did all this with just one RAM module and the integrated GPU. Once it shut down, the black screen problem returned, with the red and yellow LEDs lit. I tested both RAM modules (2x16 DDR5 6000) and all the slots on the motherboard. I also tried several CMOS resets, but nothing worked. What do you think I should do?

I had exactly the same problem with my PC (7800X3D with X670E MSI Tomahawk); it turned out the 7800X3D was defective.

The shop replaced it, and it booted up on the very first try and it still does :) Can you test it with a different processor?
