Guys I need help right now I have an MSI B550 Torpedo and I’m trying to flash it so I can use my Ryzen 5 5600x cpu but the bios light stays on and not flashing. Should I wait like an hour to turn off the system since I know it’s bad to turn off while bios process is going on.

Hi everyone,

I just bought a Ryzen 7 9800x3D with an MSI X670e Gaming Plus Wifi mobo.

During first boot the CPU debug light went red. I was expecting this since the CPU is quite new and mobo BIOS is probably not to date. So I tried flashing the most recent one on my new mobo.

It's not my first time, it usually goes fine. I use an old Imac to format a 4Gb usb key to FAT32, download new bios, rename the exec MSI.ROM, put on the key, plug it on the flash USB port and hit the flash button.

Problem is, the red light start bliking but never stops or acclerate or slow down. It just keeps blinking for hours

What should I do ?

I wanted to write about my own experience with updating the BIOS on a MSI motherboard for anyone upgrading to 3rd Gen Ryzen, as the stuff I read online were not very helpful.

My setup is: B450 MSI Tomahawk, Ryzen 5 3600

Download the latest BIOS Version from MSI's website and then copy and paste only the BIOS file to a FAT32 USB Thumbdrive of less than 16GB. Leave the text file alone, don't copy that.

Rename the BIOS file to MSI.ROM

Shut down your PC, unplug the power cord and locate the CMOS Battery, which is a button cell battery. Either short the two pins beside the battery labelled BAT1 for 5 to 10 seconds or remove the battery and wait at least 20 minutes before reinserting.

Don't install the CPU yet. Plug your PC back in and turn it on. If you use the same mobo as me, you should see that the red LED on the top right near the 24 pin ATX connector for the CPU should be lit up.

Plug in your thumbdrive into the BIOS Flashback USB Slot on the back of your mobo then press the small button above it. The red LED on the top LEFT side of the mobo should start flashing. Do not turn off the PC or wiggle the thumbdrive. If the LED flashes for less than 5 seconds, repeat the steps again, you might have done something wrong.

Let the LED Flash. After a while your PC should restart. Switch it off again and install your CPU and the rest of your components.

You should have successfully completed your BIOS update and brought your non-X570 motherboard up to date. Good luck!

Hey everyone,

I recently updated my MSI motherboard’s BIOS using MSI Center in Windows. The update process appeared to finish — there were no errors or crashes — and then the screens went blank. I figured this was normal and waited 5–10 minutes, assuming it was part of the reboot process.

But nothing happened.

Eventually, I restarted the PC, and that’s when I noticed the CPU EZ Debug LED was solid. No display output, no BIOS screen — just a powered-on system with the CPU light on. I then shut it down, waited a few minutes, and powered it back on. Same result — CPU debug light still on, no boot. Fans are spinning, lights are on etc as you can see from the pictures.

I’ve watched a few YouTube videos to understand what might be happening. Most of them recommend trying things like clearing the CMOS, reseating the CPU and RAM, and using BIOS Flashback. I haven’t attempted anything yet — I’m just trying to make sense of the situation before diving in.

What I’m struggling to understand is, why would I need to reseat the CPU or RAM when the system hasn’t been touched physically at all? It hasn’t been moved or bumped, and everything was working fine before the BIOS update. Is this just a general troubleshooting step that helps for unrelated reasons, or is there something about a BIOS update that could make those components behave oddly?

Would really appreciate any insights or similar experiences. What should I do :(

I was tearing my damn hair out trying to make my motherboard flash the new BIOS (regardless of version as long as it supports 3000 series).

Like a lot of you guys I had issues where I knew I was doing everything right and following the instructions but it still wouldn't flash and some people had to switch usb drive, but if you are like me and only have one usb drive in your apartment and want to save yourself a trip to the store this is how I fixed it. If this turns out to be an actual fix for peoples flashing problems somebody should really make MSI post this along side their instructions!

Simply put it seems like you need to restore your USB drives to their original state (I won't pretend to know what that means but it seems like regular Windows formatting doesn't do that and so no matter how many times I formatted it would not work). I have a B450 GAMING PLUS but I think it should work with all your Tomahawks aswell.

To fix this follow these instructions to restore your USB; https://www.pendrivelinux.com/restoring-your-usb-key-partition/

(Just follow the instructions for Bootice and make sure its FAT32 as file system).

Use this tool to do it: https://www.majorgeeks.com/files/details/bootice_64_bit.html

It worked instantly when I plugged it in. I really hope this helps guys I was so happy to finally get it working and wanted to share the solution for me and hopefully for you too! V18 worked for me only because that's the one I had downloaded.

EDIT: Unfortunately, as is with all things AMD and MSI, the story doesn't have a happy ending. I keep getting Windows crashes on a fresh install and it's just crazy, can't even download Ryzen master or anything. Really disappointed in all of this, especially MSI.
