- If the BSOD persists, back up critical data and perform a clean installation
The 0x000000D1 (DRIVER_IRQL_NOT_LESS_OR_EQUAL) BSOD is typically caused by drivers accessing memory incorrectly at elevated IRQL levels, unstable memory, or conflicts with kernel-level software.
To resolve this error effectively:
- Disable Driver Verifier if enabled.
- Update or roll back problematic drivers.
- Repair system files using SFC and DISM.
- Test RAM and verify disk integrity.
- Remove conflicting third-party utilities.
- Reset BIOS or UEFI settings and keep Windows updated.
If the issue continues, an in-place repair or clean installation ensures a permanent fix. Maintaining stable drivers, healthy memory, and updated firmware helps eliminate the 0x000000D1 BSOD and restore long-term Windows stability.
