Case: Savio Raptor X1 ARGB Case - https://www.savio.net.pl/en/product/savio-raptor-x1-argb-case-mesh-glass/
Bios: AMI BIOS 7B89v2E 2022-01-19 , Update to AMD ComboAM4PIV2 1.2.0.5, have used 7B89v2D too.

Core parts are all brand new (CPU, PSU, RAM, MOBO, NVMe), bought a week ago.

>>Bought a week ago my new parts, i put everything together for my first time, had the pc to work for several days, and then all of a sudden during my 1st livestream, 1 hour in, it did its 1st sudden shutoff-autorestart sequence. From that moment until today (4 days) it keeps doing it very often in every aspect of windows tasks. PC keeps shutting off & auto-restarting in every process that im doing, apps installation, drivers installation, windows installation, windows updates, loggin to windows, starting the pc, troubleshooting, everywhere. I havent got a single BSOD yet, nothing, not even an error message, it only shuts off on its own and tries to restart, it gets stuck sometimes on loops. I keep reinstalling (clean install) the windows 10 from my USB, the lucky attempts that will make it through will have the same fate a few mins later when i let windows update take over. And after the random shutoff it is unable to complete the installation of the <cumulative update for windows 10 version 21h2 for x64-based Systems (KB5010342)>, either it gets stuck there (pending) or shuts off when it tries to install it. It does it on video driver installation too, tried different driver versions, no hope. I have access to BIOS (which im using mobo's latest but tried the previous too), after that problem begins.

>>What have i have tried so far but the problem persists like nothing changed:
Opened case and disassembled everything and put it back together (done twice)
Installed windows 15-20 times from scratch (still does it, even during windows installation)
Installing windows on M2 NVMe & SATA SSD seperately (does it on both disks)
With and without GPU installed (with integraded grahics)
With and without secondary disks attached (SATA)
Applied thermal paste on to CPU (three times)
Monitored temps, nothing was overheating
Did startup repairs

I just spend all my free hours trying things to see what is the cause of the problem. I cant narrow it down. I need help guys, at least what is the source of this, is a part that i bought missfuctioning or faulty? is it software or hardware related? It keeps shutting off and tries to restart. I had to enter safe mode to be able to type and post this thread without crashing. Is this considered as crash? It shuts off instantly with no error or screen message and immediately tries to reboot.

Please any help is much appreciated & needed. Im lost :/
 
Is the PSU unit powerful enough for the new components?
It isn’t clear but did the problem begin before or after you updated the BIOS?

PSU is 600w, it should be more than enough for Ryzen 5600G. GPU is not that much demanding. But the thing is that it still does that with the bare minimum components (no gpu, no extra disks).
Bios:
1644599099431.png

When i bought everything, first thing i did is to flash the motherboard to it can support the 5000 series cpu. I picked 7B89v2C version in order to be safe. Turned out when i assembled eveything, PC couldnt post anything, couldnt start to bios. It could only spin fans. So i decided to flash the next bios update, 7B89v2D. With that i got it to access bios, installed win 10, did windows updates, installed drivers, apps, games, everything and had it to work for a few days. Then the problem appeared, installed the latest version 7B89v2E, where it stands so far.

I literally cant access desktop, the moment it tries to log in to windows it shuts off. It gets stuck on a shut-restart loop until it shows me the troubleshoot blue screen where i can pick boot with safe mode, in order to actually log in and access my pc and go online to reply.
 
Are you using fast startup? If so then disable this while in safe mode.
I would go back to the original BIOS version & see whether that fixes the problem as it sounds like the newer BIOS is the cause.
 
Reverted back, doesn't matter still does it :(
Im trying to install windows for the 30th time, i almost know my win key without looking at it, it wont complete the full installation, it shuts off when im even picking yes to that option, EVERY TIME!
What is it so powerful that gets in the way even in windows installation :(

I would recreate the installation media on another pc if possible which will download 21H2. Also there’s no need to enter your key if you sign in with a Microsoft account as Windows will be activated as soon as you sign in.
 
its weird, starting with bios. My motherboard's manufacturer has released 3 bios updates from which on ryzen 5000 series are being supported (like I showed in previous screenshot). In order for my 5600G cpu to work i need to flash the bios on the motherboard which is why i got a mobo that has a flash bios button. It is the first thing to do before connecting anything, so that's what i did ! Connected 8 & 24pin cables, the usb, power, and did it before putting anything on. To be safe though i flashed with the oldest of these three supported bios (when i built it 2 weeks ago), which led to not being able to start (EZ debug light stuck on cpu indicator, just fans running). After checking everything, i decided to flash it again with a usb, but i didn't pull out all parts, and i put the next (2nd) bios update with all parts connected, it seemed fine and successful because pc came to life after that and for the next week. After the problem started, one of the hundreds things i tried is to flash again the bios to the most recent update but again i did it with some parts on, which led to the same disastrous behaviour. In the duration of the problematic period i was going back and forth with the bios updates in my desperation to test everything. But, yesterday when i decided to disassemble again everything, i thought it would be nice to try flash the bios the "suggested" way, with nothing on the board. Thats what i did, put the latest version once more, and since yesterday pc is running fine with no strange shut downs or crashes. Its weird because if that was the actual fix, i had no idea that i had to flash it like this, because when i was searching for it, noone said it MUST have be done with the motherboard bare naked, more like you COULD do it with no cpu or other parts. And the other weird thing is that it doesnt work with the first update that introduced 5000 series to b450 motherboards like it says on msi's site, only the last two are able to recognize the cpu. I hope that is it, im installing things very anxiously on my pc just thinking it might break the whole thing again if its not bios related :/
 
I must say, I haven't done a heap of BIOS flashing, maybe a dozen or so over my time, and I have never done it, or heard otherwise, that the mobo should be bare naked.
you are only forcing new firmware code into the BIOS chip - who cares if the drives (or any component) are connected or not.

but... a win is a win.
time will tell. :)
 
Hapiness lasted for a day :(
I installed windows, windows updates, drivers, utilities, apps, games. And then as i was sorting out music files it shut off like someone pulled the power cable. And then the usual reboot/crash cycle began. When i power the computer, it tries to load, flashes screens, tries to get to login screen, it crashes and reboots. After a couple of times it shows the troubleshoot screen. If i manage to get in to desktop and press shut down it cant. it will crash right when showing "shutting down" and it will restart instead. Only way to shut down the pc is either from troubleshooting screen or pulling the power cable.

I have recorded a 2min video of this sequence of nonsense that it will go forever.

I have questions?

Please do not write one solid paragraph makes things hard to read and to make sense of. (Thank you)

Have you tried booting with just the just the M2 attached think that has the OS on it?
All you will need to do is disconnect the power and data cables from the other drives.

Have you ran a Check Disk on this drive WDC 1 TB?
From what read it did not crash per say until you started transferring music with that drive being the age that it is may be starting to show its wear.
 
The issue persists on the minimum components. Cpu, ram, psu, m2. Not using gpu, nor the other 2 disks. :/
 
Others may have more to add...

Can you even access Safe Mode on the minimum components?

After you installed Windows, you installed the Chipset then the rest of the drives in the correct order?
Where did the drives come from and what program was used?

Gone through the BIOS to make sure that everything is configured correctly?
Turned on or off XMP and set the RAM to 3200?
 
I just lost faith trying things for 2 weeks not being able to see what was causing it.
Brang the tower to a local service, when he figured out that motherboard is causing the issues, the hdmi & displayport of that mobo are not functioning correctly and they create an unstable condition, even if they're not being used (with dedicated gpu). He said is a well known problem of that specific model of msi (b450m mortar max) that other users have experienced as well.
I'm gonna try ask for replacement it to see if thats the case. I hope they ll accept my request to get me a new one, hopefully not with the same issue :/
 
cool.
let's close this for now and if you need help down the track, of course open a new thread.
good luck :thumbsup:
