Understanding and Resolving AMD GPU Error Code 43 After Switching Driver Software: A Case Study
Introduction
Encountering hardware errors can be a frustrating and complex process, especially when they emerge after software updates or changes. One common issue faced by users is the AMD Error Code 43, often associated with hardware device malfunctions within Windows. This article examines a real-world scenario where a user transitioned from AMD Adrenalin to AMD Pro Software, leading to the GPU becoming unresponsive and generating Error Code 43. We will explore potential causes, troubleshooting steps, and solutions to help others facing similar challenges.
Case Summary
The user operated an AMD Radeon Pro WX 5100 graphics card on a system configured with:
- GPU: Radeon Pro WX 5100
- CPU: AMD Ryzen 7 2300X
- Motherboard: ASUS Prime X470-Pro
- Operating System: Windows 11 (initially Home, upgraded to Pro)
Initial Conditions and Changes Made
The user initially utilized the AMD Adrenalin software, with the GPU functioning normally. A decision was made to switch to AMD’s Pro Software, despite both versions being based on the same driver build. Prior to installation, a system restore point was created, but attempts to revert failed. Post-installation, the driver appeared to install correctly; however, launching AMD’s application resulted in a compatibility error stating the software was not compatible with the device.
Consequent Symptoms and Findings
Following the software change, the problem persisted despite multiple troubleshooting attempts:
- Error in Device Manager: Error Code 43, indicating Windows cannot start the hardware device.
- Management and Diagnostic Tools:
- CPU-Z displayed partial information about the GPU.
- No signs of physical damage; the GPU had been reseated.
- BIOS was fully updated, with no overclocking or unstable configurations.
- Software and Driver Removal:
- DDU (Display Driver Uninstaller) was used in Safe Mode to remove existing drivers.
- Multiple clean installations of Windows 11 were attempted.
- Reinstallation of AMD Adrenalin software did not restore functionality.
Analysis of Possible Causes
Several factors could contribute to this issue:
- Driver Incompatibility: Despite identical driver builds, the Pro version may have introduced incompatibilities or corrupted driver files.
- Firmware or Hardware Lock: Transitioning to the Pro driver might have triggered a firmware lock or compatibility restriction not supported by the GPU
