Troubleshooting the AMD Radeon RX 6400: A Guide for New Users

If you’ve recently purchased an AMD Radeon RX 6400 graphics card with the hope of enhancing your gaming experience, you may be facing some frustrating challenges. It’s common for users, especially those who aren’t very tech-savvy, to encounter difficulties when upgrading their systems. Today, we will explore why your Radeon RX 6400 might not be functioning as expected in your Dell OptiPlex 5050 SFF and suggest some troubleshooting steps.

Understanding the Compatibility Issues

First and foremost, it’s important to ensure that your PC is compatible with the new graphics card. The Dell OptiPlex 5050 SFF is designed to support various hardware configurations, but there are certain prerequisites when installing a new GPU.
