On the previous functional system, the CPU debug LED displayed a red signal.
System: MSI X570 A-Pro (with 7C37vHI BIOS), Ryzen 7 3700X, 2x16GB G.Skill Ripjaws V 3200Mhz, Asus RTX 2080 Super, Corsair Carbide Spec-06, 1x256GB 960Evo, 1x1TB 970Evo Plus, plus several hard drives (Corsair RM2019 750W 80+Gold). Recently upgraded to a 13600K with ASRock Z790 PG Lightning/D4. I attempted to use my existing RAM but faced issues. Now I’m considering a future upgrade to DDR5 memory. Everything functioned perfectly before, but now I see a red CPU debug LED and no POST. I’ve tried reseating components, cleaned everything, inspected connectors, and cleared CMOS. I’m still curious about the reliability of those debug lights and want to test alternative RAM options, especially since some indicators might not be fully accurate. Any advice would be helpful.
