Question I can't flash the BIOS in any possible way on my MSI B550-A PRO ?

[rainb]

Hello, I really need help.
First of all sorry for my grammar, english is not my first language.

Yesterday i was building PC, i got everything into my motherboard and wanted to test if it gonna boot to a BIOS, sadly didnt. Then i was reading a forum and I found that ez debug light was lighting a BOOT notification, so I wanted to bios flash. I was reading few hours how to do this on this motherboard, I was already doing this couple of times on my old PC so i was familiar with it. First I was doing it while my components were on the motherboard, the board was working, the PSU was spinning, there was a light on a board but red diod was blinking like 15min each time i was trying diffrent sticks.

There was all the time the same, the red diod was blinking more than a 10min, no progress, then i was turning off a PSU and trying to format the sticks in the diffrent ways and I was trying diffrent a versions of a BIOS. Then I was reading more about it, I disconnected all of the components from the motherboard, and first time after this, there was again like this, the PSU turned on, the light was blinking really quick for like +20min and nothing happens.

Then i disconected PSU and was trying again diffrent stick, even diffrent format system (FAT instend of FAT32). And now, the motherboard doesnt recognise any of the sticks (ofc i formated them later to the FAT32). The light is just blinking normally (not quick) and the PSU doesnt want to turn on when i hit the flash buttom. When i just click start bottom, the motherboard is working, PSU turning on instantly and the CPU light is on (there are no components on board). I was restarting CMOS battery multiple of the times. I really dont know what I can do to fix it. I will be extreamy greateful if somebody help me.

Welcome to the forums, newcomer!

Be quiet 550W
What is the model for your PSU?

1TB MSI Mv2
Can you pass on a link to the M.2 drive?

Msi B500-A Pro
Is this the motherboard;
https://www.msi.com/Motherboard/B550-A-PRO
you're working with?

Just an FYI, if you didn't have a boot drive to begin with, you could've just gotten a warning message stating that no boot drive was detected and you'd still be able to get into the BIOS. The BIOS out of the box would've been enough to help you diagnose if your CPU was faulty to begin with.

Hey guys, I made already one topic https://forums.tomshardware.com/thr...any-possible-way-on-my-msi-b550-a-pro.3832239 and I returned the board RMA I got a brand new b550 a-pro. So there is a deal.

I unboxed the board and first thing that I tried to do on a clean board w/o any components was a flash bios. I downloaded the lastest version and put a stick, there was a bliking red for a few secound then later a solid red light. Then I thought ok, then maybe the bios update isnt nessacery or there is already latest on the board. I checked and the motherboard was made 04.2023 so should be anyway compatible with my CPU (Ryzen 5600). So i plugged everything on board and tried to post. NOPE, there was a ez bug led on the CPU position. Then i tried to do a flash bios with diffrent sticks, the red light was blinking 20+min everytime. Im hopeless, its already my 2nd board and I cant freaking post a bios. Is there a problem in CPU then? I really dont know please help me 🙁

Btw PSU is be quiet 550 so there is no a problem i guess
no kidding I can even transfer somebody 20$ if i will solve is somehow :|
