I decided to swap my Ryzen 5 2600 for a Ryzen 7 3700x. The system will not turn on, its like there's no power at all, the only thing lit is the GPU led when the PSU is switched on. Replacing the 2600 and it fires up as normal. I tried a 3600 which also works as normal. Put 3700x back in, nada. The mobo is an MSI B450M pro m2 max. Said to support this cpu, and works ok with the Ryzen 5 3600. The cpu looks fine. all pins appear ok. I quickly benched up my msi x570 gaming plus (the crap one) with a new tt grand 650w psu. Same problem. Wont work with the 3700x. Is there something specific I need to do with a Ryzen 7 3700x that could cause this problem , or, is the cpu dead?

During CPU replacement, you must reset the CMOS. If it doesn’t work, erase the CMOS, install the 2600, and then refresh the BIOS.

Hey there! Looking great in the forums! Just a heads up—if both your motherboard BIOS and 3700X aren’t compatible, you might run into some issues.

Thanks, that makes sense. It’s not just a typical no-post issue. The power isn’t reaching the PCB on the switch, and I’ve reset the CMOS multiple times. After spending some time troubleshooting, I think the CPU might be faulty. I’m hoping someone else has faced the same problem with this CPU.
