Motherboard : MSI b450 M PRO VDH
Cpu : Ryzen 7 2700x

Hello everyone.
I am a new member here and joined the community because I need help with my system. I have a MSI B450 A Pro with ryzen 7 2700x cpu. Recently I faced an issue with my samsung evo 960 m2 drive. My system could not read it, neither it showd in bios or in windows 10 setup. I tried many things but in vain. Then I decided to update my bios. I downloaded the latest bios version from Msi site for my mobo and flashed it in m-flash mode. It went perfectly but after that I am facing another issue. Now my system won't past the ez-led checks. The led is stuck on CPU and cpu fan is whirling like crazy...
I have no idea what I did wrong or how to solve this problem and get my system running again... Please help.

So was it the 1st time you were trying to use this SSD?

Anyway, I'd unplug PSU and wait 10 minutes so that all capacitors are empty. Reseat CPU, GPU, RAM and try booting again. Should go directly to BIOS.

Hi.. thank you for your reply.
No, I had windows 10 installed on this m2 drive and it was working fine until 2 days ago, when a bluescreen appeared stating winlogon.exe or something was not readbale. I figured it was the drive. It was not showing up in bios or in Windows setup where drives are listed to format and fresh installation. I tried to update my BIOS hoping it would resolve the m2 issue but now, aftet flashing a latest bios version via m-flash option given in bios, my system is stuck. It does not complete the boot process and the cpu led light is on constantly.
I have unplugged psu from the board as you said and will try to boot again. Will update here..

Hi seoulFinn
So I did as you instructed. Plugged out the PSU from the board and waited for about 15 min. But ths problem is still the same.. I don't know however if this resets all parts or do I have to do any other steps... Is there anyway to rollback to the previous bios version..? Or to flash the new bios version again..? Maybe I missed a step or did something wrong...

Good to know that the SSD worked at some time. Turning the PC off for minutes and removing components should be enough. Of course pressing "clear CMOS" on mobo is not wrong either.

Do you have any other hard drives (SSD or HDD)? If you have, what happens in you remove m.2 and leave other drive in? Does the system recognize it, let you go to BIOS?

If you can, I would also try booting up with a new installation media on a USB stick. If the BIOS is not corrupted and in your boot up priority USB is listed, there is a chance you can reinstall Windows this way. Go to https://www.microsoft.com/en-us/software-download/windows10 to create USB stick. Must be at least 8Gb in size.

There should not be any problems reflashing the BIOS again. Not sure you can flash older version, thou. I would try this 1st before anything else.

Yes I have another SATA 1tb but it's unplugged as of now. I don't want anything crazy happening to it since it has all my important data. Yes I could see the SATA drive in bios before I tried to flash new bios. I already have a Windows 10 bootable usb readymade and it boots just fine to windows setup. But that was before I flashed new bios. Now I can't do any of this as my system is not doing anything except showing cpu led light all the time. Does not go any further...😑

Googled. Downgrading BIOS should be possible using USB thumb drive and that button. But maybe the BIOS file you used got corrupted? Try downloading it again and reflashing.

The problem is I don't have a thumb drive... And even if I had it, my system wouldn't detect it, I have another usb drive with just the Bios Rom in it, but the system can't detect it... I suspect the bios version I flashed got corrupted and since there is no bios, the board is not detecting anything connected to it... Now I figure I have to find a way to flash a bios in this corrupted board state...

How big is this usb drive and how did you prepare it for bios flashing?

You need Fat32 format of the flash drive for bios upgrade.

Does the system boot with Live Linux Flash drive? This is to test whether the system actually boots up; I am not suggesting to install Linux; I never do!

Hello Laurence

The usb I had was a 16gb kingston. I had windows 10 setup files in it. I just copied the bios folder and used m-flash from my previous bios version to enter into bios flash mode. Then I just browsed to the actual bios file and proceeded further. The flashing went just fine, but after it completed it never booted again and only the cpu led is lit constantly. The cpu is whirling at full speed...

Hi.
Thank you for the reply.
I guess my usb drive is in fat32 format.
I don't have live linux flash drive, and now I don't even have other means to make one... I have another usb drive with just the bios rom in it, but now the system does not read it. I hope my board is not bricked...

It really sounds like the BIOS file got corrupted somehow. Things would be so much easier if this motherboard had "BIOS flash button" in the back, which this particular model does not have. :(

Yes.. I hoping for this as well.. I even searched my board but didn't find any button like this...
What could possibly be the way now that I am stuck in this situation...? I have searched internet for over three days now... But couldn't find anything helpful..

Just a thought, but could it be that the newest BIOS you flashed doesn't support 2700x anymore and that's why the CPU light is on? I know it sounds crazy, but some ROM chips are very limited in size.

If you have a friend with for example Ryzen 3600 maybe the board will boot with it? Sorry, I'm not really helpful here.

That's all right. I really appreciate that you replied and tried to help me out.
Yes.. the new bios not supporting ryzen 2700x might be the case.. Msi should really warn the users before they actually download these updated bios files about the compatibility cases with older cpu's.. Any ways.. thank you for your help.. really appreciate it..☺
Unfortunately I don't have a friend with ryzen 3000 series near by.. If I can't find any workaround I think I'll have to contact some technical guy to fix my board..

This is me: "Damn, the new BIOS and CPU don't work together. Time to upgrade!"

Didn't MSI tell us few days ago that all of their 400-series boards will support Ryzen 5000 series CPUs? (Will need BIOS upgrade, so you'd still be stuck.) But 3000 series CPUs are good too. I suppose used Zen 2 processors (i.e. 3700x and 3900x) ones can be had for "peanuts" soon.

Hope you get this thing sorted out and soon. Good luck!

Just out of curiosity I d/l the latest 7A38vM7 BIOS. On a txt file it says:

1. This is AMI BIOS release
2. This BIOS fixes the following problem of the previous version:
- Update AMD ComboPI1.0.0.3ab
- Fix RAID issue.
- Support Ryzen 3000 series CPU.
Ryzen 9 3900X/Ryzen 7 3800X/Ryzen 7 3700X/Ryzen 5 3600X/Ryzen 5 3600/Ryzen 5 3400G/Ryzen 3 3200G
- Change BIOS UI to Click BIOS(GSE-Lite) mode.


It looks like it's time for an upgrade! Congrats! :p

My bios text file says something different.
Attached screenshot.

May be the problem is now my mobo does not support the ryzen 7 2700x.. Screenshot_20201020-173310.png
