MSI B550M PRO VDH WiFi ( CPU LED ON)

Posted by Alert-Increase-2838@reddit | buildapc | View on Reddit | 6 comments

I have bought a used MSI B550M PRO VDH WiFi and I tried to flash bios in order to use my 5600X. So I tried many BIOS versions but whenever I put the usb and press flash button. It will keep flashing at the same speed for around 6-7 minutes. Then the bios flash led will stop flashing. But the CPU LED will keep on.

Any suggestions?

when you try to turn on your pc, is it set up correctly? it has ram, it's all plugged in, etc.

No no. I am trying to update the bios first. because the 5600x is not compatible with the MSI B550M PRO VDH WiFi motherboard. So

ok, well it sounds like your bios is updating successfully. so you should just try it.

No. the CPU LED should turn off the update. But in my case the CPU LED is on. check this https://www.youtube.com/watch?v=MYL88wjbmbI&t=359s

the manual say nothing about the debug LEDs:

Please download the latest BIOS file that matches your motherboard model from the MSI® website.
Rename the BIOS file to MSI.ROM, and save it to the root of your USB flash drive.
Connect the power supply to CPU_PWR1 and ATX_PWR1. (No need to install CPU and memory.)
Plug the USB flash drive that contains the MSI.ROM file into the Flash BIOS Port on the rear I/O panel.
Press the Flash BIOS Button to flash BIOS, and the LED starts flashing.
The LED will be turned off when the process is completed.

I did that. Now I have the 5600x and one stick of ram plugged on the motherboard. But the CPU LED is permenantly on when I turn on the motherboard
