How To Resolve Nvlddmkm.sys Error and Fix Display Driver Crashes
So, if you’re playing games or just doing some basic stuff and suddenly your screen goes black and then pops back up, that’s usually a sign something’s off. Sometimes it’s just a dodgy connection — like your power supply or maybe a loose HDMI/DisplayPort cable. But more often, it’s your graphics driver throwing a fit. Especially the Nvidia ones; you might see that message in your logs: “Display driver nvlddmkm stopped responding and has successfully recovered.” That’s the driver basically telling Windows, “Hey, I’m crashing, but I got this.”
By the way, it’s kind of weird, but if this error keeps popping up, you might also start crawling towards a Blue Screen of Death (BSOD).Not great, because that obviously slams the door on your PC’s health — and it’s usually related to driver conflicts, overheating, or power issues. So, fixing that NVLDDMKM error can save you from hardware headaches later.
How to Fix NVLDDMKM Error (Display Driver Stopped Responding)
Run the SFC and DISM tools
First things first, corrupted system files can mess with drivers. The System File Checker (sfc /scannow) and DISM (DISM /Online /Cleanup-Image /RestoreHealth) commands are your friends here. They’ll scan and repair Windows core files and system images, which sometimes fixes that driver crash issue. Stuff inside C:\Windows\System32 can get hinky, and these repair commands help clean things up.
- Hit the Windows key + R, then type
cmd. When it pops up, hit Ctrl + Shift + Enter — yep, run as administrator (because Windows loves to make it tricky). - Once in the Command Prompt, type
Sfc /scannowand press Enter. Watch it do its thing. If it finds messed-up files, it’ll try to fix them automatically. - After that finishes, time for DISM. Type and run these in sequence:
DISM /Online /Cleanup-Image /CheckHealthDISM /Online /Cleanup-Image /ScanHealthDISM /Online /Cleanup-Image /RestoreHealth
Once everything’s done, reboot. Sometimes that alone works wonders, especially if Windows’ system files are causing driver hiccups.
Disable Link State Power Management
This might sound like a chunk of tech jargon, but it’s actually simpler than you think. Your PC’s PCIe slot can cut power to the GPU to save energy, but in some setups, that’s *exactly* what causes the driver to crash. Windows can be overly aggressive here, so turning off this feature helps stabilize things.
- Head over to Control Panel — you can search for it or get there through the Start menu.
- Set the View by to Large icons, then click Power Options.
- Select your current plan and click Change plan settings.
- Click on Change advanced power settings. A new window opens.
- Expand PCI Express (click the ‘+’ sign), then expand Link State Power Management.
- Change both On battery and Plugged in to Off. Then hit Apply and OK.
Reboot. This can stop Windows from aggressively throttling your GPU, hopefully making driver crashes less frequent. On some machines, it took a couple of restarts or toggling the setting back and forth, so don’t get discouraged if it doesn’t work the first time.
Disable High Precision Event Timer
The HPET — High Precision Event Timer — helps sync stuff for smoother gameplay, but weirdly enough, it can also cause your GPU to go unresponsive. Disabling it might fix the nvlddmkm issue if it’s linked to this timer.
- Press Windows + X and pick Device Manager.
- In the Device Manager, expand System Devices.
- Locate High precision event timer. Right-click it and choose Disable device.
Check Your Power Supply
If your PC’s power supply is running on thin ice, giving less-than-adequate juice to the GPU, that can make the driver crash — especially under load. You can peek into BIOS (usually by pressing Del or F2 during boot) to see voltage readings for the GPU power rail. If the voltages are irregular or below the recommended spec, that’s a sign it’s time to replace the PSU.
Reset Fan Control Settings
Fan control software manages temp, but misconfigured fans can cause overheating. If your GPU runs too hot, it might be crashing the driver to protect itself. Reset your fan profiles to default and make sure fans are spinning correctly with no strange noises. Good air flow helps keep those driver crashes at bay.
Adjust MSI Afterburner or Overclock Settings
For gamers, tools like MSI Afterburner tweak your GPU’s voltage and clock speed. But raising clock speeds beyond stability point can cause freezes or crashes. Disable low-level IO drivers or hardware access in MSI Afterburner — those are prime suspects for causing driver crashes. Always revert to default clock speeds first, then test your system.
Swap Graphics Card Slots
Sometimes, the PCIe slot itself is acting up, or dust’s got it dirty. You can try removing the GPU and plugging it into a different PCIe slot. Be gentle, and remember to clean the contacts with some compressed air. If switching slots helps, it’s a hardware issue, and replacing the motherboard or slot might be necessary. But at least you can narrow down the culprit.
Underclock the GPU
If your GPU is overclocked or even just heavily customized, it could be causing instability. Try underclocking via MSI Afterburner or resetting BIOS to default settings. Sometimes, less is more — a cooler, less stressed GPU is less likely to crash the driver.
Change TdrDelay Setting
The TdrDelay value controls how long Windows waits for the GPU to respond before resetting the driver. Increasing it can help avoid BSODs, but it isn’t exactly a cure — more like a delay tactic. Be extra careful here, because editing the registry can mess things up if you’re not careful.
- Press Windows + R, type
regedit, press Enter. - Navigate to
HKEY_LOCAL_MACHINE\ SYSTEM\CurrentControlSet\Control\GraphicsDrivers. - If you don’t see TdrDelay, right-click in the right pane, choose New > DWORD (32-bit) Value, and name it TdrDelay.
- Double-click it (or right-click, choose Modify) and set the value data to 5 (seconds).Make sure Base is set to Decimal.
Check Your RAM
Faulty memory can cause the driver to crash, since the GPU relies on system RAM. Run Windows Memory Diagnostic (type MdSched.exe in Run) and restart your PC. It’ll scan your RAM for errors.
If you have two RAM sticks, test each one individually. Remove one, boot up, and see if the driver crash stops. Repeat with the other. If one stick causes problems, replace it. If you only have one stick, you might need to buy a new one for testing.
Update or Roll Back Nvidia Driver
Keeping your driver up-to-date helps, but if the problem started after an update, rolling back might be the fix. Use Device Manager — expand Display adapters, right-click your Nvidia card, choose Update driver (or Roll back driver if that option is there).Or, better yet, download the latest driver directly from the Nvidia driver downloads page.
Reinstallation of drivers can be cleaner if you use tools like GeForce Experience to handle driver cleanup and updates.
Update Windows
Old Windows can cause driver conflicts, so keep everything current. Go to Settings > Windows Update and click Check for updates. Sometimes, Windows updates solve these driver hiccups without even touching your graphics card.
What Causes the NVLDDMKM.sys Blue Screen?
If the driver’s really stubborn and stops responding hard, you’ll get a BSOD instead of a quick recover. The list of reasons? Overheated GPU, outdated or corrupted driver, bad RAM, or a weak power supply that can’t keep up — basically, any hardware stressor that makes the driver hang or crash.
Long story short, fixing that driver crash involves checking hardware stability, updating or reinstalling drivers, cleaning your PC, and tweaking some advanced settings if needed. It’s a bit of trial and error, but these steps cover most of the common culprits.
- Overheated GPU — check temps, clean fans, reapply thermal paste if needed.
- Outdated driver — update or roll back.
- Faulty RAM or GPU — test hardware parts.
- Low power — verify PSU voltage using BIOS.
