Try reinstalling your DirectX software, if you're having trouble with applications that require the GPU for processing or rendering.

Please use this application, Display Driver Uninstaller. DDU removes any conflicting drivers and software related to the GPU and allows you to install the latest drivers from scratch.

If you need a detailed guide: How to Clean Install your Video Drivers.

Extract the download, open the app and allow it to extract its own files, finally, run the new executable. DDU will ask if it can do the recommended option of restarting in safe mode, doing so will restart the system and load DDU again, if not please navigate back to the app and open it. Choose the highly recommended option of Clean and Restart, once completed the system will return to regular Windows, possibly with a lower resolution. Reinstall the appropriate drivers from NVIDIA or AMD/ATI.



It's possible that it could be an issue with the registry, try this after clean installing the drivers.

  1. Start regedit.exe
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
  3. Right-click the right-side pane. If running 64-bit Windows, select New > QWORD, or select New > DWORD if running 32-bit Windows.
  4. The new key name should be 'TdrDelay' (no quote marks) and the value should be 8.

Try a GPU benchmark to test for any anomalies.

If the issue continues, depending on your type of system you may need to reseat the graphics card (resolve's black screen/no display issues as well).

If this is a notebook, we suggest changing the thermal paste on the GPU as well. See:  Thermal paste replacement/Overheating prevention

If those solutions do not work, it could lay deeper in the foundation of the operating system. Possibly an issue with the OS, try a clean install if all else fails.
