Question PC won't boot and the motherboard's DRAM light is blinking ?

[Notsohuman401]

Hello everyone, im helping a buddy of mine to fix his problem , he was using his pc like usual and suddenly his pc rebooted with dram light blinking yellow. I tried using only one stick, still won't boot but the light on motherboard keeps switching from CPU to DRAM, and when I put the second ram module back in, only the DRAM light starts blinking, not the CPU one Can anyone help please?

Heres what i tried so far:
1-Trying each stick of ram individually
2- Reseting cmos
3- Checking cpu for any bent pins
4- Tried using a different gpu
5- Tried using different rams

PC specs:
Mobo: Asus Tuf Gaming B550M Plus
CPU: Ryzen 7 5800X
GPU: RTX 3060 Ti
RAM: 32GB
PSU: Cooler Master 620w

try resetting cmos

or replace the coin battery 2032 with a new one.


but i would bet its probly the power supply as its quite old as its a triple rail psu which isnt even a 620w psu really its closer to 520w on the 12 rail.

i would replace that regardless with a seasonic gx 750w gold or equivalent psu

are you making sure the ram is in slot 2/4

update the bios to latest version

https://www.asus.com/uk/motherboard.../helpdesk_cpu?model2Name=TUF-GAMING-B550-PLUS

its possible the board stopped working as it had the wrong bios

i own the same board and while it booted with the ryzen 7 5800x it wasnt using the correct bios which caused instability.

You do not need a cpu to update the bios just a usb stick formated to fat 32

the bios file

Not all boards have it but that particular one has it. I tend to buy boards that have this feature as its handy for when a rogue bios screws something up.

Thats pretty useful indeed emma keep it in mind next time i go for an upgrade, may i ask which bios should i download the one that says b550 bios update or the cpu specific one ?

i would say the cpu specific one

however since the lastest bios fixes security issues with ryzen i would download it
