How to Fix IRQL_NOT_LESS_OR_EQUAL BSOD After Installing New RAM

The IRQL_NOT_LESS_OR_EQUAL Blue Screen of Death (BSOD) can occur for various reasons, especially after installing new RAM. This article provides a comprehensive guide to troubleshoot and potentially resolve this issue by walking you through several steps.

Understanding the IRQL_NOT_LESS_OR_EQUAL Error

The IRQL_NOT_LESS_OR_EQUAL BSOD indicates a critical system error that disrupts the normal operation of Windows. It often indicates an issue with the kernel or drivers, which can be caused by incompatible or faulty hardware, especially newly installed RAM.

Troubleshooting Steps

1. Check RAM Compatibility

Firstly, ensure that the new RAM is compatible with your motherboard. Consult the motherboard manual or specifications for supported RAM types, speeds, and maximum capacities. Incompatible RAM can lead to system crashes and BSOD.

2. Reseat the RAM

Power off your computer and unplug it. Open the case and carefully remove the new RAM modules. Reseat them firmly in their slots to ensure a proper connection. Ensuring that the RAM sticks are properly seated can resolve many BSOD issues.

3. Test Each RAM Stick Individually

If you installed multiple RAM sticks, test each one individually:

Remove all but one stick and boot the computer. Repeat for each stick to identify if one of them is faulty.

4. Run Windows Memory Diagnostic

To further diagnose memory issues, run Windows Memory Diagnostic:

Press Windows R, type mdsched.exe, and hit Enter. Choose to restart and check for problems. This will run a memory test and report any issues.

5. Check BIOS Settings

Access the BIOS/UEFI settings to ensure that the RAM settings, including speed, voltage, and timings, are correct. Consider resetting to default settings:

Enter the BIOS/UEFI setup during boot, usually by pressing F2, Delete, or Esc. Adjust or reset any RAM-related settings.

6. Update Drivers

Outdated or incompatible drivers can cause BSOD errors. Ensure your drivers, especially for the chipset and any graphics cards, are up to date:

Visit the manufacturer#39;s website for the latest drivers. Download and install the updated drivers.

7. Check for Overclocking

Overclocking can cause stability issues. If you have overclocked your RAM or CPU, revert to stock settings to see if that resolves the issue:

Check the BIOS for overclocking options and reset them to stock.

8. Check for Other Hardware Issues

Ensure that other components such as the motherboard, CPU, or power supply are functioning properly. Inspect for any physical damage:

Check for loose connections or damaged components. Perform a visual inspection for any signs of overheating or wear and tear.

9. Run System File Checker

Run the System File Checker (SFC) tool to check for and repair any corrupted system files:

Open Command Prompt as an administrator. Run the command: sfc /scannow.

10. Reinstall Windows

As a last resort, if none of the above steps help, consider backing up your data and reinstalling Windows:

Run a system restore to a previous point before the issue started. Backup your important files. Reinstall Windows and test if the BSOD issue is resolved.

Conclusion

To successfully resolve the IRQL_NOT_LESS_OR_EQUAL BSOD, start with the simplest steps, like reseating the RAM and checking compatibility. If the issue persists, proceed to more complex troubleshooting. If the problem still isn’t resolved, it may be worth consulting a professional technician for further assistance.
