Windows 11 BSODs, SSD detection issues, failed stress tests – need help diagnosing root cause

I’m asking for help to understand and fix a serious issue I’ve been facing with my Windows 11 laptop. I’ll explain everything from the beginning in order, because the problem evolved over time.
System
Laptop: PCSpecialist Valeon LI 17 (Tongfang GM7RGXM / similar to XMG Neo 17)
CPU: Ryzen 9 6900HX
GPU: RTX 3080 Ti
OS: Windows 11
Storage: NVMe SSD (original system drive failed, now using a replacement NVMe)
What happened (timeline)
Initial problem – system instability
Windows 11 started crashing with BSODs.
Eventually I got UNMOUNTABLE_BOOT_VOLUME.
System would not boot into Windows anymore.
Recovery & installation attempts
Windows Recovery and System Image Recovery could not find the SSD.
At some points, the SSD was not detected at all in recovery tools.
BIOS could sometimes see the NVMe drive, sometimes not.
Secure Boot / BIOS changes
Secure Boot was enabled by default.
Windows installation only worked after disabling Secure Boot.
After that, I managed to clean install Windows 11 again.
New errors after reinstall
After reinstalling, I encountered MEMORY_MANAGEMENT BSOD.
Windows setup restarted multiple times during configuration.
Eventually Windows installed, but stability was questionable.
SSD health testing
I scanned the SSD using CHKDSK → no errors reported.
I also scanned it with CSKCD (disk check tool) → no problems found.
However, when I run an SSD stress test, the system blue screens (BSOD).
The crash happens specifically under heavy SSD load.
Current situation
Windows can boot now.
SSD is detected.
Light usage works.
Any SSD stress test causes a BSOD, despite disk scans showing no errors.
I’m unsure whether the issue is:
a failing SSD,
NVMe controller / firmware issue,
motherboard / NVMe slot problem,
BIOS issue,
or Windows 11 driver conflict.
What I’m asking for help with
How to properly diagnose whether the SSD is truly failing if normal scans pass but stress tests crash.
Whether this behavior points more to:
SSD hardware failure,
motherboard / NVMe slot instability,
BIOS or firmware problems,
or Windows 11 NVMe driver issues.
What tests or logs I should check next (Event Viewer, dump files, SMART tools, etc.).
I’m open to any structured troubleshooting steps.
Thank you very much for your time and help.
If you want, I can:
shorten this for Reddit,
make it more technical (dump files, bugcheck focus),
or adapt it to Microsoft Answers / TenForums / Reddit r/techsupport.

what is the make and details of the NVMe SSD please.

best of luck Steve ..

Force mp 600

Tempted to wave a finger towards the NVME drive, easiest way to test would be to swap it out, fresh install windows and see if the problem has gone, it it persists.

Even a stable boot off an older Sata drive would narrow down the issue. by ruling out memory etc.


CystalDiskMark might get it to throw errors if something is up with the drive.

you might not get any good system logs on the fault because it the drive faulting.

I tried crystal disk mark and everytime i run the test i get blue screen of death

Stress Test your memory too.
Make sure the nvme drive is making good contact in the socket.
If you have another nvme socket, try it.

Ok i will feed back once i stress test the memory i already tried the other socket and the problem presist

the force MP600 NVMe doesn't have HMB so that rules that out.
please check
control panel > security and maintenance > maintenance > reliability monitor
for any errors and error codes

then check
window tools > system information > components > problem devices
see if if anything is recorded there please.

best of luck Steve ..

I will do that once i am near my laptop
Thank you

Well i can even use my laptop for more than 1 minute i get bsod then reboot to bios after i checked there were no ssd detected
Now i have to get a new ssd and see if the problem still
Thank you guys for trying to help me

Have You looked if any new BIOS is available for your laptop ?

Unfortunately pcspecialist they don't want to give me the latest bios version
Because i don't have the necessary information that proves i i am the owner of the laptop as i bought it second hand from someone who doesn't have them either but xmg have the exact chassis like nine and they are providing there bios update for anyone to download
And as im no expert in stuff like this i don't know the amount of risk I'm putting myself into
