nvlddmkm.sys BSOD
I guess that this irritating nvlddmkm.sys BSOD crash bothers quite a few people, so in the next few minutes I’ll explain how to permanently solve this error. I’ve researched this topic for quite a while so this is going to save you a lot of time and frustration.

About this file
It is part of your Nvidia® display driver installation, and it is located under the following path: nvlddmkm.sys fileC:\windows\system32\drivers

Description of the problem
Blue screens of death crashes (STOP errors) associated with this file usually occur on all popular Windows platforms: XP, Vista, and even Windows 7. Crashes might occur randomly or at different situations such as immediately after installing Windows, while trying to install new video display drivers, or while playing video games.

Other reported problems related to this nvlddmkm.sys are that it involves in slowing down Windows startup process.

Source of the problem
The good news is that there’s one general point of failure that causes this problem – that is a driver(s) problem. I deliberately wrote driver(s) and not just ‘driver’. Indeed the first and most obvious possible point of failure is your Nvidia® display driver; however it might be another problematic driver such as a motherboard driver that might be causing all that trouble.

From some reason your Nvidia® display driver and/or one of your other system/motherboard drivers are either obsolete or corrupted.

How to solve the nvlddmkm.sys BSOD
Warning! - Don’t manually try replace that file under any circumstances by another one. Many users try to download that file from random sites, and then they experience other problems. It just doesn’t work that way.

In order to solve the problem you need to make sure that your Nvidia® display driver as well as all your system drivers, and motherboard drivers aren’t outdated/corrupted, and if so, replace them with their ‘healthy’ and most updated versions.

Doing that manually is a time consuming, too risky, and inaccurate task. (You can never tell which are the most updated and exact required drivers). Anyway, I found that the safest (and by far the fastest) way to replace those problematic drivers is by using a reliable drivers repair tool.

To summarize - in order to repair this nvlddmkm.sys BSOD run a quick drivers scan and at the end see which drivers are causing this error, then install their latest, official, and most updated versions.

A little request...
Since each of you got a differently configured OS, Iíd like to know the exact symptoms that you encounter with this problem. Feel free to post this information at the bottom of this page. Thanks.


Tip – In order to avoid various problem in the future, I highly recommend you to periodically (say once a month) verify that all your drivers and I mean all of them, including your Windows, hardware devices, etc. are intact and most updated.

I have a windows 10 os whenever I run games it gets hanged and the BSOD comes on and says driver irql not less or equal. What failed nvlddmkm.sys.

I've spent weeks on this and tried everything. I finally went directly to the Nvidia site, had their online scan self-detect and got the latest driver set downloaded. I had to install Java to use the scan try several times to download and install without errors. While on the Nvidia webpage, down in the corner in fine print, I saw: This graphics card not compatible with DirectX 11. I had just upgraded from XP on an old machine to Windows 7. I couldn't click through on many websites like onine banking. Chrome and others stopped updating Old ‚ÄėUnsecure‚Äô XP with latest functionality, so they finally killed XP for me. Windows 7 has DirectX 11 built in. I tried deleting it in the registry and only lost my system restore points. DirectX 11 wasn't supposed to reinstall, but there it was after restart and my registry entry for DirectX is now messed up. I can't revert to a restore point before the registry changes. The DirectX 9 installer didn't work before or after the registry changes. Repeatedly. Before the registry changes, it appeared to install 9 but in logs showed failure, after registry changes it shows error onscreen and installation failure message. The nv at the start of the driver name points to Nvidia graphics card so you might want to find the online self-scan page and see if your video card is also incompatible with DirectX 11. If so, only a newer graphics card seems the answer. I upgraded all system drivers many times and even tried old ones from XP days. So, blue screen again when I woke up, just waiting for a restart. Several times a day. I want to update the bios but if you bluescreen in the middle of the process it kills your motherboard.

Hello there. I have Blue Screen problem, the earlier version is undocumented but the recent one are this one. The first time I get BSOD is after I install Cities: Skyline (my pc not meeting it's requirements) so I refunded it. Then the next day I tried to play Mass Effect 1 but in the middle of the gameplay I got crashed(my pc is far too superior for it to be error). Afterwards I botice that every game I play will result in BSOD (which is not previously). I run my antivirus to find 2 birus and 1 corrupted config and repaired it. Then I play another game and still the same crash, do you know anything about it? Thanks.

Its now 2016 and the same thing in happening. I have been bothered with this since Windows 10 never heard of it before. looks like its still not fixed why?

I had the following error this afternoon: STOP: 0x0000007E...
nvlddmkm.sys - Address FFFFF88005D381DC base at FFFFF880058DB000, Datastamp 507db70d
I've tried looking for the nvlmddmkm.sys file, but apparently my laptop does not have it. I can only find the nvlmddmkm.sy_ file, in my Nvidia file folder. Should I just reinstall the driver? I did that the second time this happened, and apparently it hasn't fixed it (this is the third time). Although, I did find three other older versions of the nvlddmkm.sy_ file, which I deleted. They are sitting in my recycling bin as I type this. My laptop is a Lenovo T420 running Windows 7 64 bit. Thanks.

Hi Luke,

Where did you get that driver from? Anyway I suggest you to run a quick drivers scan via the above tool - see if it indicates anything regarding NVIDIA, if so replace that driver with the suggested up-to-date driver. Let me know if that solves the problem.


Mike D Aug 19, 2012

i got "There are no items to display." from Driver Manager on ParetoLogic PC Health Advisor.

I guess there is nothing to update but this problem is still happening.

Yaron Aug 19, 2012

In that case the problem might occur due to a corrupted NVIDIA display driver so I suggest you to do the following:
(1) Remove your NVIDIA display driver
(2) Restart Windows
(3) Run another drivers scan
(4) The missing NVIDIA driver should be detected and it should let you download the latest certified version of that driver that matches your specific hardware

Let me know if that solved the problem.

Keith Jul 24, 2012

I downloaded the latest drivers from Nvidia and I'm still getting the blue screen.

Admin Jul 24, 2012

Hi Keith,

First you need to uninstall your NVIDIA driver, then restart Windows, and then install the latest compatible version of your NVIDIA card - did you do that?

Also, you might have downloaded an incorrect/incompatible driver - after removing the driver run another drivers scan via the above drivers tool - it should notice the missing driver and suggest a matching (compatible and certified) replacement driver for you to download.

I'd also suggest you to scan all your other drivers (via the above drivers tool) to see if any of them are outdated/missing. Replace ALL outdated/missing drivers and see if that helps.

Let me know if that solves the problem.

Keith Jul 20, 2012

I get the same thing when trying to play any game (AoE III, Sins Of A Solar Empire, etc.). The screen will go dark momentarily and then I'll get hit with the Blue Screen.

Same as Tim Lee, screen goes black then long delay and BSOD with the nvlddmkm.sys as the problem. Happens during video game (BF3) and during flash player videos.

Tim Lee Jul 3, 2012

Every once in a while our screen just goes black and then a blue screen with a bunch of stuff on it including the nvlddmkm.sys show up ... I will try and fix it now and let you know.
