RAM and CPU indicators are displaying red, while the PC fails to boot.
PC specifications: Ryzen 9 3900XT, Asrock B550 Phantom Gaming, 4 PCIe slots, Crucial Ballistix RGB, 16GB (8x2) DDR4-3200 memory, MSI 850W power supply (brand new model unknown), Zotac RTX 3080, 10GB RAM. PSU model uncertain but appears to be a recent release. I’ve been experiencing boot issues where all lights illuminate and fans spin initially, but the system only starts after several seconds. Once running, fans reach maximum speed as per BIOS settings, indicating it should boot eventually. Recently, these problems have become more frequent. I tried removing one RAM module and another CPU, but the PC still won’t boot. Now I’m considering a CPU replacement to diagnose the issue. Could you confirm whether the problem lies with my current CPU, motherboard, or RAM?
You're asking about possible causes of the problem. If the RAM is correctly placed, it should fit snugly without any space. Make sure all modules are fully inserted. Consider removing the CMOS battery briefly to reset the BIOS before trying to boot again. Determine when these issues began. Check if anything changes after swapping and reinserting the CPU. It might be wise to back up the system and update the BIOS first. Generally, B550 boards can support the 3900X, but stability is a concern here. If your system worked before but now has boot problems, the issue likely isn't with the CPU, motherboard, or PSU—unstable power could be the culprit. For testing, remove the GPU and run the system with a less demanding version. Inspect the CPU for bent pins; otherwise, it’s unlikely to fail unless it was overclocked.
Bent pins in an AMx socket typically prevent CPU installation because of the socket design. It’s unlikely this is the main problem. The real cause might be stability issues from the motherboard. Also, RAM shouldn’t move much after proper installation—this could be contributing.
I purchased a fresh RAM module that matches the motherboard, but the problem persists. As soon as I turn on the power, the CPU and RAM indicator lights stay red and don’t change.
