Hello, I'm assembling a PC for my girlfriend using some existing components. The setup includes an i3-12100f with a stock cooler, MSI B660M, Crucial Ballistix 3200 DDR4 8GB, an old RX480, EVGA G2 550W, and an old Evga display. Yesterday the system failed to boot, likely due to a dead motherboard. We replaced the motherboard and now the CPU LED is blinking but the PC still won't start. After removing all cables and reconnecting everything, I reinserted the CPU and swapped the stock cooler for the new one. I verified the power supply works fine (though I haven’t tested another supply yet) and tried different RAM. The motherboard supports both 8-pin and 4-pin power connectors, but I’m only using the 8-pin PSU as it’s the only one available. Could it be that the CPU is faulty? Or should I try other troubleshooting steps before replacing it? Thanks!

I used a 960 model, but it didn’t function properly. The CPU debug light remains active, and it doesn’t post.

Remove the CPU and examine the motherboard connectors. Once confirmed safe, reinstall the CPU and attempt again.

I successfully solved the issue—it looks like the CPU power cable or PSU CPU power is faulty. I tested a paperclip short to verify the power supply, which confirmed it was working, so I didn't think about the PSU. Thanks for your assistance!
