If you keep getting hit with the IRQL not Less or Equal Code, you're most likely dealing with an outdated driver or operating system. Sometimes, the memory related error can pop up because of your anti-virus. Disable it and see whether this helps.

Although I have not faced the error code before, a friend of mine did. She kept seeing the blue screen of death, along with the error. She panicked and came to me for help. Turns out, she was dealing with corrupted network adapter drivers.

I've run through all the fixes to try below. Keep reading.


How Do You Fix IRQL Not Less or Equal Error Code?

There are several ways to fix the memory address stop code, and they include:

Malware attack on PC

Solution 1: Remove USB Devices

Plugging in incompatible hardware or USB devices can cause the driver IRQL error to appear. All you need to do is remove power cables (or any external devices), restart your computer, then check whether your windows system is still acting up.

Solution 2: CPU Overheating

You may not be facing any serious hardware or software problem. Instead, your CPU may just be overworked. Let it cool down for an hour or two and then try again.

If your computer overheating is something that you struggle with, regularly cleaning your CPU, and closing your system's case can help. You might have to upgrade your CPU fan if it's old too.

Solution 3: Check System Driver

A lot of the time, outdated and incompatible device drivers can cause the BSOD error (blue screen of death). Sorting this is easy. All you need to do is upgrade all your graphics drivers.

You will be able to fix Windows IRQL not less or equal stop code in a matter of seconds:

You should be good to go now. In case you get hit with an error message saying that the latest drivers have been installed already, follow the below steps to double-check this.


Solution 4: Roll back Drivers

If you're dealing with incompatible game controller drivers, updating them will only help if there is new firmware. You can try rolling back the latest update, and going back to a previous version instead.

Here's what you do:

Solution 5: Update Windows System

Are you still having trouble? Upgrading your operating system version might help. Along with the BSOD error, you might be dealing with a bunch of other problems as your Windows operating system has bugged out.

Now, you will need a stable internet connection to update your OS. Here's what you do:

Update on keyboard

Solution 6: Disable Redundant Antivirus

Sometimes, you may have more than one antivirus program installed. It can interfere with the Windows runtime and Kernel picture, ultimately causing the driver IRQL not less error to appear.

The only way around this would be to uninstall any old anti-virus that you don't use anymore. I would recommend going all the way and getting rid of third-party options and using Windows Defender instead. It's on par with everything on the market, and some users think it's better too.

Here's how to uninstall an antivirus that you don't need:

Solution 7: Modified or Reinstall Network Adapter

I touched on buggy drivers earlier, but corrupted adapter drivers can be responsible too. Although this may seem hard to fix, uninstalling your network drivers and then re-installing them again can help.

Follow these steps:

Solution 8: Reinstall Intel Rapid Storage Technology Drivers

Although I haven't had luck with this, several users that I know have been able to fix the issue by re-installing their Intel Rapid Storage Technology Drivers.

Here's what you do:

Solution 9: Disable Memory Cache

Write caching can cause the error to pop up. To work around this, disable your computer's memory cache. In case you're wondering, you won't lose any important data in the process.

Here's what you do:

While you're at it, you can disable windows write-cache buffering too. However, you should only try this if you have a backup power source, like a UPS.

Solution 10: Check Your Memory Allocation

Last but not least, your RAM might be faulty and causing Blue Screen of Death errors.

To check whether your RAM frequency is responsible, you will have to scan your memory card.

There's a built-in tools on Windows 10 that can do this.

Here's how you use the memory diagnostic tool:

If the memory diagnostic tool says that there's an issue with your RAM, you will have to change it. Here's how:

Alternatively, you can use a third-party tool like MemTest to find out whether you're facing any problems.
