To fix this error, you’ll need to either update, remove, or manually allow the driver, depending on your system setup and needs. Below are several methods you can try, starting from the easiest fixes to more advanced ones.
1. Uninstall GIGABYTE Utilities
Note: If you don’t use GIGABYTE utilities for RGB control or system tuning, this is the simplest fix. Uninstalling them won’t affect your system performance and will remove the problematic driver. Some GIGABYTE utilities include drivers that are not fully compatible with newer Windows security features. Tools like App Center, RGB Fusion, Aorus Engine, and EasyTune rely on the Gdrv2.sys driver to manage hardware controls such as RGB lighting, fan speed, and performance tuning. However, features like Memory Integrity and Windows Driver Signature Enforcement can block this driver due to potential security risks. Uninstalling these utilities removes the Gdrv2.sys driver from your system, which can resolve this error and prevent future conflicts.
2. Check for Driver Updates
An outdated or unsigned GIGABYTE utility driver often causes this error—especially if Memory Integrity is enabled in Windows. To fix this, try updating the GIGABYTE utility that installed the Gdrv2.sys driver. Visit the official GIGABYTE Support page, enter your motherboard model, and download the latest version of the utility (such as App Center or System Information Viewer). If a signed and updated version is available, installing it should prevent Windows from blocking the driver. You can also try updating the driver from the Windows Device Manager utility. Here’s how: If no update is available or the issue still persists, consider uninstalling the utility completely or disabling Memory Integrity (not recommended unless necessary).
3. Disable Memory Integrity Setting
The Memory Integrity feature in Windows helps protect your system from malware and unauthorized drivers by blocking anything that appears unverified or potentially unsafe. It is part of a security layer called Core Isolation. However, this feature may prevent certain drivers—like the GIGABYTE Gdrv2.sys driver—from loading, especially if they’re not properly signed. Disabling Memory Integrity can sometimes allow these drivers to run, but keep in mind that doing so will reduce a layer of protection in your system. Only proceed if you’re confident the driver is safe and from a trusted source.
