Question 1

Install fails or rolls back?

Accepted Answer

Remove any existing GPU driver with DDU in Safe Mode, reboot, then run the GWTC71427 installer as administrator. Disable antivirus temporarily if it blocks the driver package.

Question 2

Device not detected?

Accepted Answer

Reseat the GPU, confirm PCIe power cables are connected, and check BIOS settings such as primary display and Above 4G Decoding. In Windows, use Device Manager > Scan for hardware changes.

Question 3

Version conflicts?

Accepted Answer

Uninstall the old driver package before installing the new one. Pause Windows Update driver replacements, install the vendor driver matching GWTC71427, reboot, and verify the driver version in Device Manager.
