How to Fix Driver Problems Found in DXDiag

Q: What does DXDiag Notes section show when there is a problem?

When DXDiag detects a driver problem, the Notes field at the bottom of the affected tab shows a specific description instead of No problems found. Common messages include information about unsigned drivers, driver version conflicts, missing hardware, or DirectX feature limitations. Read the exact message carefully — it typically identifies the specific device and the nature of the problem.

Q: DXDiag shows no problems but my game still crashes — what does that mean?

DXDiag only checks for driver installation problems and DirectX component health. If DXDiag shows No problems found but your game crashes, the issue is likely: a game-specific bug that requires a game patch, RAM instability (run Windows Memory Diagnostic), overheating GPU (check GPU temperature under load), or a game installation problem (verify game files through Steam or the game launcher). DXDiag cannot diagnose these issues.

Q: How do I fix an unsigned driver warning in DXDiag?

An unsigned driver warning means the driver does not have Microsoft's digital signature. To fix this, download the latest official driver from the hardware manufacturer's website — specifically look for a WHQL-certified version. Uninstall the current driver through Device Manager or Display Driver Uninstaller (DDU) for GPUs, then install the official signed version. After reinstalling, run DXDiag to confirm the WHQL Logo'd field shows Yes.

Q: Can a driver problem in DXDiag cause blue screens?

Yes. Driver problems identified by DXDiag — particularly with display drivers — can cause Blue Screen of Death (BSOD) errors. Common BSOD codes related to GPU drivers include nvlddmkm (NVIDIA), atikmpag or atikmdag (AMD), and igdkmd64 (Intel). If you experience BSODs alongside DXDiag driver errors, update or reinstall the affected driver. For NVIDIA GPUs, use Display Driver Uninstaller (DDU) in safe mode to fully remove the old driver before installing a fresh copy.

Driver problems in DXDiag appear in the Notes section at the bottom of the Display or Sound tabs. The most common fix is to update or reinstall the driver from the manufacturer's official website. Run DXDiag again after updating — if Notes shows No problems found, the problem is resolved.

How to Find Driver Problems in DXDiag

Open DXDiag (Windows + R, type dxdiag).
Check each tab — System, Display, Sound — and read the Notes field.
"No problems found" = healthy. Any other text = a problem to investigate.
Save the full report (Save All Information) to keep a record.

Fix: Display Driver Problems

Step 1 — Update the GPU driver

Download the latest driver from NVIDIA, AMD, or Intel's official website based on your GPU. Install it and restart.

Step 2 — Clean reinstall for persistent problems

For recurring display driver errors, use Display Driver Uninstaller (DDU) in Windows Safe Mode to fully remove the old driver, then install a fresh copy:

Download DDU from its official website (guru3d.com/files/display-driver-uninstaller/).
Boot into Safe Mode (hold Shift while clicking Restart).
Run DDU, choose GPU type, click Clean and Restart.
After restart, install the fresh GPU driver.
Run DXDiag to confirm Notes shows No problems found.

Fix: Sound Driver Problems

Step 1 — Update the audio driver

Go to your motherboard manufacturer's support page (for onboard Realtek audio) or your PC manufacturer's support page (for laptops/branded PCs). Download and install the latest audio driver.

Step 2 — Check Device Manager

Press Windows + X, click Device Manager.
Expand Sound, video and game controllers.
If any device shows a yellow exclamation mark — right-click it and select Update driver.
If no driver is listed at all — click Action → Scan for hardware changes.

After Fixing — Verify with DXDiag

After updating any driver, run DXDiag again and check all Notes fields. They should now show No problems found. If a problem persists, the DXDiag Notes message provides the specific issue to investigate further.
