Écran bleu DRIVER IRQL INFERIEUR OU ÉGALE
Hi everyone,
I'm having a problem (a blue screen appearing) with my PC lately, and I haven't done anything special...
The stop code is: DRIVER IRQL NOT LESS OR EQUAL
and the failing element is: nvme.sys
I've had this before (multiple times) when I didn't reach out to the experts on this forum; it was related to the drivers of my Wi-Fi card if I remember correctly... The connection would drop, the PC would freeze, and then the blue screen. I looked into it and tinkered a bit and it didn't happen again... (I reinstalled the drivers, tried to update) but here it's apparently a different error and alone.
Can you help me fix this? I haven't done much special, and I don't really understand why Windows is suddenly targeting me...
Thanks in advance

Panth33raHello,
A preliminary response found on the CCM Forum... https://forums.commentcamarche.net/forum/affich-37274093-blue-screen-driver-irql-not-less-or-equal
It mentions a driver "nvme.sys" or a device not properly seated in its slot. Check if it's securely in place.

IHaveAQuestions AuthorIs it normal that the link you provided is the link to my topic?
And do I have to disassemble my computer then? -
IHaveAQuestions AuthorThank you, and how can I do this concretely?
Moreover, what I forgot to mention is that when I put my PC to sleep and then leave for half an hour, when I come back and press the space bar to wake it up, I often (maybe not every time but almost) encounter a blue screen.
And then it restarts, and once I return to the Windows desktop, I notice that there is the same sound as when an USB drive is unplugged. However, I haven’t plugged anything in, so it's my SSD, or it makes a sound for no reason... but I don't believe in a loose connection because I can flip the PC in all directions, it doesn't unplug. And as I said, it is flat when this happens, clearly when I wake it up from sleep mode.-
brucineSee here:
https://lecrabeinfo.net/demarrer-windows-10-en-mode-sans-echec.html
Safe mode will successively load all drivers and will crash at the first error, which allows you to identify the culprit, but it is indeed likely that in these conditions it is not the SSD itself but its controller.
No alerts in the device manager, no recently hastily updated driver?
Once identified, the first thing to do is to see if there is a driver update that resolves the issue, but it may also be a hardware failure.

IHaveAQuestions AuthorHi, I started in safe mode and it didn't crash. It loaded, then I quickly found myself on the desktop.
I even took a screenshot of the device manager. (I even started in safe mode with networking, but the wifi didn't work). Here is the screen.
Thanks-
Panth33raHello,
Check here... https://treexy.com/products/driver-fusion/database/network-adapters/mediatek/wi-fi-6-mt7921-wireless-lan-card/ there is the driver(s) for your network card. -
brucine@Panth33raCertainly, but if the screenshot is in safe mode, there is no evidence to suggest that the network card is more to blame than other devices on alert, remaining to be seen if the situation is the same in the device manager during normal startup.
The various lines of investigation are summarized here:
https://neosmart.net/wiki/irql-not-less-or-equal/ likely remaining and if nothing works, a failure of some more or less removable hardware (RAM, Disk Controller...).
Malekal offers a number of tests for this purpose: https://www.malekal.com/diagnostiquer-les-problemes-materiels/

brucineHello,
I saw that too, but the reported error is not exactly the same (except perhaps for a Samsung SSD).
In any case, if this is related to that Windows bug, it's a lesser evil since there is an optional Windows Update for versions 2004 and 20H2, with 21H1 seemingly not affected, so if this is the problem at hand, the first step is to directly upgrade to 21H1 if possible.
https://www.bleepingcomputer.com/news/microsoft/microsoft-fixes-windows-10-bsod-crashes-caused-by-nvme-ssds/ -
-
brucine@IHaveAQuestions19042 corresponds to 20H2 possibly targeted by the bug; install the optional update as reported in my link or upgrade to 21H1.

IHaveAQuestions AuthorIn normal mode, I don't see any orange warning triangles. Not even on the network map.
As I said before, I had encountered this issue before, and with whocrach or something like that, it would give me errors that would come suddenly in the middle of a video after a certain time, and it was related to my network card. Since then, I've tried reinstalling the drivers, and it seemed to be fixed.
Here, lately, it's the nvme.sys that's bothering me, and that one crashes when I take it out of sleep mode. I would be surprised by a loose connection; the PC is new, it's one month old. Yet when I watch 4 hours of a lecture, it doesn't flinch... -

IHaveAQuestions AuthorHi, the issue with the network card has come back. The PC freezes, I lose connection, then a blue screen. I didn't have time to take a picture.
I also just got this when coming out of sleep even though it's not the same error.
I also found this: https://www.malekal.com/driverscloud-mettre-a-jour-ses-pilotes/
So I think my drivers should be fine... At least I hope.
How can I get out of this hell? I don't understand why Windows is so hard on me when it's practically brand new.

I had the same error code on one PC --> 0xc000021a (PC for office use, no games, etc...)
I reinstalled W10 (clean install) from a 128GB USB stick that I formatted in NTFS instead of FAT32
I had tested with a 16GB USB stick in FAT32, and the PC wouldn't boot from the stick... why, I don't know
The PC is working fine now

=============
For your questions in the previous messages:
I even took a screenshot of the device manager. (I even started in safe mode with network support, but the Wi-Fi didn't work). Here is the screen.
For devices with alerts in the device manager in safe mode, that's not normal
In normal mode, I don't see any orange alert triangles. Not even on the network card.
In theory, that means your drivers are up to date since you don't have any alerts
I'm also in the process of installing update 21H1 since it was indeed available.
Did the update go through?

billmaximere
the problem with the error 0xc000021a is that the cause of the issue can be diverse and it's not obvious to find it
I understand that you are not enthusiastic about a clean install, but a reset without file loss is unlikely to change your problem
PS: I haven't tested this option
the thing with the network card has come back
do you have an alert in the device manager for the network card?
the pc is new, but don’t you think it could be infected?

IHaveAQuestions AuthorI don't know if a clean install would be a solution, but in any case, it would be monumental work.
I don't know if it's infected. I just restored a backup I made a few weeks ago, and it didn't change anything; I'm still getting this.

You have an issue with these 2 drivers:
mtkwl6ex.sys (MediaTek 802.11AX Wireless Adapter Driver, MediaTek Inc.)
nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 457.63, NVIDIA Corporation)
and a possible issue with the CPU temperature

IHaveAQuestions AuthorI just reinstalled from a USB stick and the same problem
it crashes, making bug noises in my headset and then a blue screen of dpc watchdog violation.
I want to say that I have a dual boot with Linux and there are no problems, so if it were a hardware issue, it would also manifest on Linux.
Personally, I think there is a problem with Windows... but I have no idea what it is and why.

I just reinstalled from a USB and the same problem
Where does the ISO image come from?
It crashes, making bug noises in my headphones and then blue screen dpc watchdog violation.
After the installation?
I must say that I have a dual boot with Linux and there are no issues, so if it were a hardware problem, it would also manifest on Linux.
Theoretically yes..., and I would say that it's the driver that is causing the problem, not the graphics card.
Personally, I think it's Windows that has a problem... but I have no idea what and why.
The error code 0xc000021a "is broad" and the problem is difficult to pinpoint.
If you can, test your graphics card on another PC.
Also test this:
Right-click in an empty area of the taskbar --> Task Manager
In the Task Manager --> Startup, disable everything except Windows Defender.
Restart the PC and see what happens with the BSODs.
If you no longer have BSODs, reactivate the programs one by one to see which one causes the problem.

IHaveAQuestions AuthorHi, the ISO came from the Microsoft site...
And yes, after the installation it crashed without much delay
I have a laptop, so it's hard to test the GPU on another PC
As for the startup programs, I disabled everything and then reactivated some like iCue from Corsair for my mouse because it wasn't lighting up anymore, but other than that, that's it.
Here, I simply restored the backup I had made because my tests were useless and reinstalling everything wasn't a solution either.
In fact, after the restore, the Wi-Fi didn't work right away, and in the Device Manager, Windows didn't recognize it immediately, I want to say. So, I connected an Ethernet cable and NO bugs, I finished a conference (no crackling in my headphones, and there's no crackling with music from my USB stick), updated everything little by little, etc... Then after some Windows updates that it did and after a few restarts, the network card was recognized again, and the Wi-Fi has been working for just under an hour. But I haven't had any BSODs.
I suspect this notorious network card (for Wi-Fi, not Ethernet then) is still bipolar. I'm wary that it will produce blue screens again soon...
And a question, my PC was resting on the chair, whereas here it's on a desk. (I know it shouldn't normally be) Does the fact that it's on fabric make airflow more difficult and cause crashes, due to tired fans or high temperature? Personally, I doubt it because I haven't seen any difference in CPU temperature, etc., so I think it doesn't change anything. It's rather just the network card drivers...
Also, for the crackling in my headphones, the drivers for the latter start with Realtek audio... and the Wi-Fi card Mediatek Wifi, etc.. But the Ethernet one: Realtek PCIe GBE, etc... Since there's a link with the names, maybe the drivers interfere.
I'm saying this because when the Wi-Fi bugs, the sound crackles and it always ends with a blue screen. Here, no crackling, so I theoretically shouldn't have a BSOD, FOR NOW, may God be with me.
Thank you

billmaximeHi
As for the startup programs, I've disabled everything and then reactivated a few like Corsair's iCue for my mouse because it wasn't lighting up anymore, but other than that, that's it.
No BSOD?
Did you reactivate the others to see if the PC crashes?
The wifi has been working for a little less than an hour. But I haven't had any BSODs since.
I suspect that infamous network card (for wifi, not Ethernet) is still bipolar. I'm wary of it possibly causing blue screens again soon...
With the updates, the drivers were reinstalled correctly, which means you don't have BSODs anymore (for now)
And just a question, my PC was sitting on the chair, whereas here it is on a desk.
If it’s a desktop PC, it shouldn’t change anything as the ventilation happens at the back and the sides
Of course, if the vents are blocked by the chair, that could cause issues
Also, for the crackling in my headset, the drivers for it start with Realtek audio... and the wifi card is Mediatek Wifi, etc. But the Ethernet one: Realtek pcie gbe, etc. Since there’s a link with the names, maybe the drivers are interfering.
No, because the drivers have different functions
Test and see what happens

IHaveAQuestions AuthorHi, thanks.
For the startup programs, I haven't reactivated everything because there were some useless ones, so I've left some disabled. Windows Defender and Ovule are enabled... I can activate them all and then restart to see if they were the issue...
Afterwards, I hope, as you say, that the problem is resolved thanks to the update, but knowing that all of this happened suddenly... I hope it won't come back in a week or even a month...
Regarding the drivers, I understand, but it's weird that I'm experiencing crackling and then a guaranteed BSOD from the Wi-Fi drivers. But when there are no cracklings, I know in advance that the Wi-Fi will work perfectly and that, in theory, it won't crash (at least for now).
I'm going to use my PC normally, hoping it holds up. I've already made a backup to restore it in case of emergency; it's always useful. And I'll contact you again if it starts happening again, but I’ll do everything I can to prevent that. ;-)
Thanks again.

IHaveAQuestions AuthorYes, I disabled all of them and it didn't change anything. So the problem isn't that...
On the other hand, when I disable my Wi-Fi card, there is nothing. So the problem seems to be with that and not a startup program in my opinion. -
