Hello friends i am having similar problem with my new system,i got it assembled on 10 sep 2019 ,since then i am experiencing system crashes with blue screen(BSOD),initially i would reinstall windows but now neither i can boot into system nor i can reinstall windows 10 ,since during reinsatallion process the system crashes with Blue screen(BSOD),I have mailed to the AMD support,but they asked me to log into my system and generate some report and send that report to them but since i can not boot into my system how can i send them the report,so i called up the support but they are not at all friendly and helpful ,they disconnected the call rudely and asked to follow the instruction as detailed in the mail,i.e to send them the report from my system , this is really fcking insane on the part of amd .Anyways my system specs are 1)CPU AMD RYZEN 5 3600 2) MBO-MSI B450M PRO-VDH PLUS 3)RAM CORSAIR 8GB*2DDR4 VENGENCE(3000MHz) 4)SMPS COOLER MASTER 550W 5)GRAPHIC CARD ZOTAC GT730(4GB DDR3), 6)SSD WD 240 GB, 7)HDD SEAGATE 1TB SATA,,. BIOS VERSION :E7A38AMS.950, BIOS DATE:22/07/2019, So please anyone throw some light on my problem,and i swear i will never ever trust AMD and its product and their support
check the BIOS on the motherboard and make sure its the latest version to support your new CPU
B350, X370, B450 and X470 can run Ryzen 3000 processors but they need a BIOS update to do that
How did you go with your issue. I'm having exact the same issue like you and still haven't found solution. I have changed all the parts accept the CPU but got the same result (BSOD). I couldn't install nor boot to Windows 10. I'm looking for and old Cpu to test for the last time to confirm if it's cpu issue.
