Encountering an “unknown error” during the installation of Nvidia drivers can be frustrating, but there are several steps you can take to troubleshoot and resolve the issue. Here’s a general guide to help you fix the problem:
### 1. **Download the Latest Driver:**
Ensure you are downloading the correct and latest Nvidia driver for your graphics card and operating system from the official Nvidia website. Sometimes, issues arise from using outdated or incompatible drivers.
### 2. **Clean Previous Driver Installation:**
1. **Uninstall Old Drivers:**
– Go to “Control Panel” – “Programs” – “Programs and Features.”
– Uninstall everything related to Nvidia drivers.
– Use Display Driver Uninstaller (DDU), a third-party utility, in Safe Mode to completely remove existing Nvidia drivers.
**Note:** Be sure to restart your computer after using DDU to remove all traces of old drivers.
### 3. **Update Windows:**
Make sure your Windows operating system is up-to-date. Sometimes, Windows updates contain bug fixes that can resolve driver installation issues.
### 4. **Disable Antivirus/Firewall:**
Your antivirus or firewall might be interfering with the installation process. Temporarily disable them while you install the Nvidia drivers. Remember to enable them again after the installation is complete.
### 5. **Install in Safe Mode:**
Try installing the Nvidia drivers in Safe Mode. Safe Mode ensures minimal drivers are running, reducing the chance of conflicts during installation.
### 6. **Check System Requirements:**
Ensure that your system meets the minimum requirements for the Nvidia drivers you are trying to install.
### 7. **Check for Windows Corruption:**
Sometimes, system file corruption can interfere with driver installations. Run the System File Checker tool:
– Open Command Prompt as an administrator.
– Type `sfc /scannow` and press Enter. Let the scan complete, and follow any on-screen instructions.
### 8. **BIOS/UEFI Update:**
Check if there is a BIOS/UEFI update available for your motherboard. Sometimes, outdated BIOS versions can cause hardware compatibility issues.
### 9. **Contact Nvidia Support:**
If none of the above solutions work, contact Nvidia support or visit the Nvidia user forums. They may have specific solutions for your particular hardware or software configuration.
Remember that these steps might vary slightly depending on your specific Windows version. Always back up your important data before making significant changes to your system.
