GPU Not Detected: Windows Troubleshooting Guide

Diagnose a mining GPU that is missing, disabled, or unavailable in Windows. This guide uses a symptom-first workflow for Windows users and avoids assuming that one setting fixes every system.

Check Device Manager and driver status

Check Device Manager and driver status. Confirm the current state first, make one controlled change, then compare the result with the previous run. Keep notes so a failed change can be reversed.

Confirm the GPU is visible to Windows before changing mining settings

Confirm the GPU is visible to Windows before changing mining settings. Confirm the current state first, make one controlled change, then compare the result with the previous run. Keep notes so a failed change can be reversed.

Review power, risers, and PCIe connections

Review power, risers, and PCIe connections. Confirm the current state first, make one controlled change, then compare the result with the previous run. Keep notes so a failed change can be reversed.

Reinstall or roll back the graphics driver when appropriate

Reinstall or roll back the graphics driver when appropriate. Confirm the current state first, make one controlled change, then compare the result with the previous run. Keep notes so a failed change can be reversed.

When to stop testing

Stop if you see unstable power delivery, abnormal temperatures, repeated system crashes, or hardware errors. Restore known-good settings before continuing diagnosis.
