IRQL_NOT_LESS_OR_EQUAL

Possible solutions

Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.

1. Reversing the driver change

   If the error started after a specific driver update, roll back to the previous compatible version.

   Steps to follow

   1. Right-click Start and select Device Manager. If Windows won't start, first go to safe mode according to the related topic.
   2. Expand the related device group: Display adapters for video error, Network adapters for network error. Do not modify the device without knowing it.
   3. Right-click the device, select Properties, then the Manager tab.
   4. Click "Return Driver". If the button is gray, there is no previous version - skip this method.
   5. Complete the wizard, save your work and reload. Repeat the action that caused the problem; do not change other drivers at the same time.

2. RAM configuration check

   If you have changed the memory or XMP/EXPO, roll back the known change and evaluate the stability and test.

   Steps to follow

   1. Use this method only if you have previously changed the settings of the processor, video card or RAM acceleration yourself.
   2. Open the same manufacturer program or BIOS menu where you made the change; take a picture of the current value.
   3. Return only your modified frequency, voltage or XMP/EXPO profile to the previous standard mode. Do not select BIOS full reset.
   4. Save and compare performance without acceleration. If you do not know the settings, leave this change to the master; have BitLocker key before BIOS steps.
