System fails to start after upgrading the Ryzen processor
Hey everyone! Three days back I got a CPU upgrade from Ryzen 3 1300X to Ryzen 5 3600. Updated the BIOS so it would work, changed the chipset drivers and it functioned fine. However, I thought my new CPU would run hotter than expected and didn’t apply much thermal paste. I decided to tweak the cooler and add more paste. When I restarted, everything powered up—RAM, system fan, CPU fan, GPU fans—but the debug LED stayed lit and the PC wouldn’t turn on. I tried swapping back the old CPU, clearing CMOS, checking power cables, opening the case multiple times, pressing the power button, and even changing the PSU, but nothing helped. If anyone knows what’s going on, please let me know! My setup: CPU Amd Ryzen 5 3600, GPU Nvidia 1060 3GB OC MOBO, MSI B450M PRO M2, 8GB RAM (crucial), 3200MHz, 400W PSU.
Initiate the boot sequence and allow it to run for several minutes.
Ensure no thermal paste is present under the CPU or inside the socket. If found, apply non-oiling contact cleaner and allow the board to dry for 24 hours. Spray only on the board surface, avoiding any additional attachments. Confirm the CPU fan cable is securely connected; some boards require it to be plugged into the "CPU fan header" to function properly.
I also took a lower frequency version from a friend, but it didn't work.
