PC fails to post after changing CPU from 3600x to 5800x.
I possess an x570 Aorus Pro with Wi-Fi and 2x16GB G.Skill Trident Z Neo 3600mhz DDR4 RAM. Prior to adding the 5800x, I upgraded my BIOS to the latest full release, F36 AGESA V2 1.2.0.7. After replacing the CPU and installing a new cooler, the system failed to boot. I verified all connections were secure and everything was properly fitted. When powering on, all fans activated at full speed, the RAM sticks illuminated, the RGB strips inside the case lit up, and the GPU display also activated. However, the motherboard lights remained inactive. My motherboard features four status LEDs; upon startup, the CPU indicator flashed, followed by the DRAM light staying steady. After about 20-25 seconds, it switched back to the CPU and then to the DRAM. Many users on forums and Reddit reported similar issues, suggesting a BIOS update resolved the problem. I've tried several recent BIOS versions, used q flash to upgrade, installed RAM in different locations, reinstalled the 3600x, and even reset CMOS multiple times. When removing the 5800x, it came out easily attached to the cooler, so I assumed it wasn't seated correctly. I installed the 3600x again and it booted normally. The BIOS also updated to F37c successfully after reinserting the 3600x. I checked the 5800x for damage and found a slightly bent pin on one side, which I straightened before the second installation. Despite these adjustments, it still doesn't boot. Assistance is needed!
Your setup sends 3600 messages every minute once it's correctly reset. That means you likely have a CPU that fails immediately.
