Part 1: What’s Behind the IRQL_NOT_LESS_OR_EQUAL Windows 10 Error?
The IRQL_NOT_LESS_OR_EQUAL Windows 10 error is a pesky Blue Screen of Death (BSOD) that points to driver or memory issues. It’s a vague error code that can feel like a puzzle, but most of the time, it’s a software hiccup you can fix without swapping out hardware.
Common Triggers
Outdated or buggy drivers: Network, graphics, or audio drivers often misbehave, especially after Windows updates.
Overclocked or bad RAM: Pushing your memory too hard or using faulty RAM can mess with system stability.
Corrupted system files: Crashes or malware can damage critical Windows files, causing chaos.
Antivirus conflicts: Overzealous third-party antivirus apps like Norton or Avast can clash with drivers.
Incompatible software: Some programs don’t play nice with Windows updates, sparking BSODs.
Ease of Use: Tracking down the cause involves basic checks like inspecting drivers or RAM, which anyone can do with a bit of guidance.
Key Features: Software issues are usually the culprit, so fixes are within reach without hardware expertise.
User Experience: It’s like playing detective, but the payoff is a stable PC once you nail the problem.

Step-by-Step: Updating Drivers
Step 1: Hit Win + X and pick Device Manager from the pop-up menu.
Step 2: Spot any devices with a yellow exclamation mark, signaling driver trouble.
Step 3: Right-click the device (try network or graphics adapters first) and click Update driver.
Step 4: Choose Search automatically for drivers to let Windows grab the latest version.
Step 5: If no updates are found, right-click again, select Uninstall device, and restart your PC to reinstall automatically.
Pros
Uses a built-in Windows tool, no extra software needed.
Hits the most common BSOD trigger head-on.
Cons
You might need to hunt down drivers manually from manufacturers if Windows comes up empty.
Checking multiple drivers can take a bit.
Ease of Use: Device Manager is straightforward, with simple options to update or uninstall drivers.
Key Features: Automatically finds updates or reinstalls clean driver versions.
User Experience: Feels satisfying to resolve crashes with a few clicks, though manual downloads can be tedious.
Part 3: Run Windows Memory Diagnostic Tool
RAM problems, whether from overclocking or faulty sticks, can spark IRQL_NOT_LESS_OR_EQUAL Windows 10 errors. The Windows Memory Diagnostic Tool scans your RAM for issues, helping you confirm or rule out memory as the cause of your BSOD.

Step-by-Step: Running Memory Diagnostic
Step 1: Press Win + R, type mdsched.exe, and hit Enter.
Step 2: Select Restart now and check for problems (recommended) to kick off the test.
Step 3: Let your PC restart and run the memory test, which takes about 10–30 minutes.
Step 4: After rebooting, view results in the notification area or Event Viewer (Win + X > Event Viewer > Windows Logs > System).Step 5: If errors show up, swap out or remove faulty RAM sticks.
Pros
Free and built right into Windows.
Simple to run with easy-to-read results.
Cons
Requires a restart, which pauses your work.
Might miss subtle RAM issues on the first try.
Ease of Use: Launching the tool is a cinch, and the test runs on its own.
Key Features: Scans RAM for defects and logs detailed results.
User Experience: It’s a bit of a waiting game, but the clarity it provides is worth it.
Part 4: Run System File Checker (SFC) and DISM to Fix Corrupt Files
Corrupted system files can mess with drivers, leading to IRQL_NOT_LESS_OR_EQUAL Windows 10 errors. System File Checker (SFC) and Deployment Image Servicing and Management (DISM) are Windows tools that patch up these files, offering a solid fix for stubborn BSODs.
Why It Works
SFC scans for and repairs damaged system files, while DISM fixes the Windows image that SFC uses. Together, they tackle file corruption that causes driver IRQL_NOT_LESS_OR_EQUAL Windows 10 crashes, getting your system back to normal.
Step-by-Step: Running SFC and DISM
Step 1: Press Win + S, type Command Prompt, right-click, and choose Run as administrator.
Step 2: Type sfc /scannow and hit Enter to start scanning and fixing files (takes 10–20 minutes).
Step 3: Restart your PC and see if the BSOD is gone.
Step 4: If crashes persist, open Command Prompt as admin and type DISM /Online /Cleanup-Image /RestoreHealth, then press Enter (needs internet).
Step 5: Run sfc /scannow again after DISM and restart to lock in the fix.
Pros
Safe tools that won’t mess with your data.
Handles a broad range of file corruption issues.
Cons
DISM needs a solid internet connection.
Multiple scans can eat up some time.
Ease of Use: It’s just a couple of commands, easy to copy and paste.
Key Features: SFC patches files, DISM repairs the system image for a thorough fix.
User Experience: Feels a bit techy, but the results are satisfying when the BSOD stops.
Part 5: Disable Overclocking and Uninstall Conflicting Programs
Overclocked hardware or problematic software, like third-party antivirus, can stir up IRQL_NOT_LESS_OR_EQUAL Windows 10 errors. Resetting your BIOS and ditching conflicting apps can clear these issues without diving too deep into tech territory.
Why It Works
