If you have System Restore enabled, restoring Windows to an earlier date is worth a try if nothing else has worked so far. Rolling back Windows will undo every system change made after a selected date.

As such, you can use System Restore to put your PC “back in time” to a moment when the error didn’t occur. It does mean you may lose some apps or data, so be sure to back up anything you want to keep.

Our guide toutilizing System Restore on Windows provides step-by-step instructions for how to roll back Windows 10 and 11. Select a restore point date created before you needed to fix the “display driver failed to start” error.

If this fixes the problem, be careful when re-installing the apps and drivers that got wiped during the restore. If you do, keep tabs on what you reinstalled and when. If the “display driver failed to start” error resurfaces, uninstall everything you recently reinstalled.

6. Perform a Windows Factory Reset

If System Restore is not an option or it doesn’t resolve the issue, you can try a factory reset as the last resort. Performing a factory reset will likely fix the “display driver failed to start” error. However, factory resetting a PC deletes all the apps that weren’t pre-installed with Windows. So, be prepared to reinstall all third-party apps you installed yourself.

You can apply a factory reset with the Reset this PC utility. That tool includes aKeep my files option you can select to keep files in your user folders (Documents, Pictures, Videos, etc). Our guide forfactory resetting Windows 10 and 11 provides details on how to access and utilize that tool.
