Ryzen System wont post. Cpu and Dram motherboard check LED keep on flashes repeatedly one after another.

I have a ryzen built pc. its ryzen 7 1700 with a gigabyte ab350 gaming 3 combined with corsair lpx vengeance 16 gb kit. Its been running nicely in a last 5 months. ive set memory timing to corsair standard, stated on its back panel from the first time i assemble it.. But today it refused to boot. Even post. And the LED indicator just switched between Cpu and dram. Onboard speaker doesnt beep. The only thing running Only cpu fan, case fans.and onboard rgb lighting. Anyone know what it means?.. Does my ram died or its power related problems maybe shorts?

Ive tried resetting cmos with jumper or batteries. But no luck

Nb. My corsair kit isnt stated on motherboards qvl list.. It works somehow until today.. Gonna check my kits on friends intel pc.

Update : my ram kit work perfectly on my friends pc. Obviously it wasnt a ram problem...

Hope anyone have an answer for my problems

Thank you.

  1. You'll have to narrow down the fault. Read this guide. You don't have to fully breadboard your system, but strip it to minimal and work from there. See if you can figure out what is causing the problems.

    Thank you for your answer, i've breadboard my system. and its the motherboard that failed. the bios wont load. ive return it for service it because its still on warranty. its weird because the system was running fine before. and suddenly the bios wont load. they change the bios chips and its working again. the last bios i use before crash is f7. wonder if its bios related bug.
