IRQL NOT LESS OR EQUAL on Windows 10 [SOLVED]

By Camilla Mo in Driver Error Tags: Blue ScreenWindows 10

IRQL_NOT_LESS_OR_EQUAL blue screen error would occur randomly especially when you are playing game. This error mostly is caused by faulty drivers, which programmed to access improper hardware addresses . To fix this error, simply try solutions in this post. 

There are three solutions to fix this error. You may not have to try them all. Just work your way down until you find the one that fixes the problem.

Solution 1: Update the drivers
Solution 2: Uninstall the problematic drivers
Solution 3: Perform a system restore


If you can’t t boot your PC normally, please go to Safe Mode and fix the error in Safe Mode (See How to go to Safe Mode in Windows 10).

Solution 1: Update the Drivers

The problem can be caused by missing or corrupted drivers. To fix the problem, update the drivers. If you don’t have the time, patience or computer skills to update the drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks:

1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to one device to automatically download and install the correct version of their driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).


Solution 2: Uninstall Problematic Drivers

The problem can be is caused by faulty drivers. To fix the problem, go to Device Manager and find the faulty drivers, then uninstall the drivers. If a driver is having a problem, you probably will see a yellow mark next to its device.

Following steps are for your reference on how to uninstall a driver:

1) Press Win+R (Windows logo key and R key) at the same time to invoke the run command.

2) Type devmgmt.msc in the run box and click OK. Then Device Manager will open. 

3) In Device Manager, locate the faulty driver. If the driver is having problem, you’ll see a yellow mark next to the device name. Then right-click on the device name (For example, uninstall graphics card driver.) and select Uninstall.

4) If prompted to confirm the uninstall, check the box next to “Delete the driver software for this device.” then click the OK button. In your case, you may not see this box. Just click OK to uninstall the driver.


5) Restart your PC and check to see if the problem is resolved.


Solution 3: Perform a System Restore

The last solution that you can try is do a system restore. If your System Protection is turned on, Windows will create a restore point before you install the driver. Then you can follow these steps to restore the driver to earlier version to fix this issue. 

1) Press Win+R (Windows logo key and R key) at the same time to invoke a run box.

2) Type rstrui.exe and click OK. The System Restore Window will open.


3) Click Next then you may see the following screen. Select a restore point that was created before the error occurred. Click Next to continue and follow the on-screen instructions to finish the restore.


4) Reboot your PC and check to see if the problem is resolved.

Hope the solutions here will help you fix the IRQL NOT LESS OR EQUAL blue screen error. If you have any questions, please leave your comments. We’d love to hear of any ideas and suggestions.

    I’ve been getting IRQL BSOD for months, and all my drivers are fine. My system would freeze at random, but typically about 3 times a day I would get the IRQL NOT LESS OR EQUAL. This was driving me nuts. I did so many things, including system restore. Still got IRQL NOT LESS OR EQUAL. I think the reason this is become so much more prevalent for everyone is with 4K monitors becoming commonplace and video cards supporting, but perhaps having issues with handling 4K – and certainly depends on how much intensity and demand you put on your system. I have a 980GTX video card, which should be able to support 3-4 4K monitors running at the same time with no problem.

    I was recently having issues with resolution on a project due to the difference in pixel density at 4k resolution. 4k is not a good resolution for web, no matter how much people want to say it is. The pixel density is way different, causing issues with CSS. Anyway, I bumped the resolution for all 3 of my 32″ 4K LG monitors down to standard 1080p. For the first day, no IRQL error issues. But my system did keep going into sleep mode after 10-15 minutes of no activity (I still haven’t looked at my power management settings, but I assume they changed when I switched resolution for the monitors). When I come back to my computer when it’s asleep, it looks like it crashed on me again, which I kept assuming. I’d hit the mouse button or keyboard key to turn the system back on, and everything is still running. I walk away to take care of something else then come back, and again it looks like my system is shut down (crashed). But sure enough, hitting the mouse button or keyboard key again brings the system back to it’s running state where I left off. It’s now been 3 days without the system crashing.

    3 days without a crash is tremendous for my system. I’ve been thinking about killing Windows 10 and switching to Linux. I’m an avid/advanced user with both and can do my designing and development on both, so going to Linux would not have killed me. I’m slammed with work though, and don’t have time to switch to Linux outside of firing up a VM. But it looks like switching to 1080p solved the problem, and this is certainly not a driver issue.

    The purpose of me writing this is because all these posts swear that IRQL issues are caused by faulty drivers. I’ve tested all my drivers, and I’ve tested all my hardware. None of it is malfunctioning. So I call BS on it being driver-related or a corruption in Windows. There’s certainly more to getting IRQL issues than just the common knee-jerk reaction of going through drivers, doing extensive memory tests, fiddling with bios settings, and so on.

    PS – I just checked my power management settings with display and sleep, and sure enough the display turns off after 10 minutes, and the system goes to sleep after 30 minutes.

    I love how this click bait article instructs you to just “locate the faulty driver and uninstall it” like we all know which of our drivers is faulty by looking at the driver name. Useless.

      Hi,

      Thanks for your comments. In Device Manager, if the driver is having problem, you’ll see a yellow mark next to it. If you’re not sure which driver is having problem, you can consider using Driver Easy. Driver Easy will detect all problematic drivers in your computer. To update drivers, you just need several mouse clicks.

      If you have any further questions, please leave your comments again.

        Your fix didn’t fix the problem. There are no drivers that show as being bad; I bought Driver Easy in the hopes it would fix the problem but it did not. I am getting random, intermittent BSODs with this error or “memory management” error and am at a loss as to what is causing them. Please help!

        • Camilla Mo

          Hi Welmoed Sisson,

          Sorry for may late reply. If Driver Easy doesn’t help resolve the problem, the problem might not the caused by driver issues. Please contact our support team at support@drivereasy.com with details for further assistance.
