Is the fan spinning?
Is the debug LED light flasing?
Probably you can also try to clear CMOS, unplug the 12-pin power core and reset the battery.

I have a similar issue with my MSI B350 Gaming Pro with latest BIOS 7A39v2NR .
  1. I installed the BIOS update 7A39v2NR with my Ryzen 1600 CPU plugged in. Reboot was fine.
  2. I switched my CPU to my brand new Ryzen 3600
  3. Black screen, only the fan are spinning, debug led are lit (but not flashing)
Big disappointment as the Ryzen 3600 was listed in the compatibility list.

Hi oxben,

Have you tried what @microthunder said to clear CMOS and unlug/plug the power cord?
According to the MSI website, 7A39v2NR is compatible with your Ryzen 3600, so it should work without issue.

How did you update bios before, do you have an earlier CPU? Only BIOS vMHR supports ryzen 3000 cpu so u need to find a way to update your bios again.

Yes, problem solved.
I've redone all the process from scratch: unplugged power cord, removed the MB battery and let it removed for several minutes (> 5min), reinstalled the Ryzen 3600 CPU and boot with a single memory module first.
And it worked!
Apparently the first time I removed the battery only for a few dozens of seconds which was probably not sufficient to clear the CMOS. Thanks for your help, I'm now a happy user of a Ryzen 3600 :cool:
