IRQL\_NOT\_LESS\_OR\_EQUAL Blue screen errors are mainly caused by driver or hardware problems. The solutions are as follows: 1. Update or rollback drivers, especially commonly used devices such as graphics cards and network cards, and give priority to using the official version; 2. Check the memory stick, clean up the gold fingers and use the Windows memory diagnostic tool to detect; 3. Disable or uninstall third-party antivirus software to avoid conflicts with the system; 4. Run the sfc /scannow and DISM commands to repair system files. If the above steps are ineffective, it may be that hardware is aging or serious system damage. You may consider reinstalling the system or replacing accessories.

IRQL_NOT_LESS_OR_EQUAL is one of the common blue screen errors in Windows systems, usually related to drivers or hardware. When this error is encountered, the system will force restart, affecting the user experience. The key to solving the problem is to troubleshoot the root cause, rather than blindly reinstalling the system.

1. Update or rollback the driver

The most common cause of this problem is that the driver is incompatible or damaged, especially the drivers of commonly used devices such as graphics cards, network cards, and sound cards.

• Update driver : Open "Device Manager", find the relevant hardware, and right-click to select "Update Driver". Priority is given to the latest version provided by the official.
• Rollback driver : If the problem occurs after the recent update of the driver, you can try "rollback driver" to the previous version.
• Manual download and installation : Sometimes there may be problems with the drivers that come with Windows. It is recommended to download the most stable version to install on the official websites such as motherboard, graphics card, etc.

Pay special attention to network cards and wireless network cards drivers. Many users report that they are "high-incidence zones" that cause this error.

2. Check the memory module (RAM)

Memory issues may also cause IRQL_NOT_LESS_OR_EQUAL errors. If you have just added memory or haven't cleaned the host for a long time, it is recommended to check it:

• Pull out the memory stick, use the eraser to erase the gold finger part, and then insert it back.
• Use the Windows built-in Windows Memory Diagnostics tool to detect memory problems (can be started with mdsched.exe when running).
• If there are multiple memory sticks, you can try to plug in only one test to troubleshoot a memory stick.

3. Disable or uninstall third-party antivirus software

Some third-party antivirus software (such as Kaspersky and Bitdefender) may conflict with the underlying mechanism of the system, causing a blue screen.

• Try entering safe mode and uninstalling these software.
• Or temporarily disable the real-time protection function to see if there will be a blue screen.
• It is not recommended to install multiple antivirus software at the same time, as it can easily cause conflicts.

4. Check system file integrity

System file corruption can also cause various blue screen problems, including this error.

• Open a command prompt (administrator permissions) and enter the following command:

   sfc /scannow

• If you find that the corrupt file cannot be repaired, you can try using the DISM command to further process:

   DISM /Online /Cleanup-Image /RestoreHealth

These two commands can effectively repair the problems of the system core files.

Basically these common treatments. Start with the driver first, then look at the memory and software conflicts, which can be resolved in most cases. If you try all of them and make an error, it may be that the hardware is aging or the system is seriously damaged. It is safer to consider reinstalling the system or replacing the accessories.
