If the screen is blinking and it feels like Explorer is repeatedly opening and closing, use this order:
- Reset the graphics driver first.
- Press Windows logo key + Ctrl + Shift + B.
- If that does not help, restart the PC.
- Check whether Task Manager flickers.
- Press Ctrl + Alt + Delete. If Task Manager does not appear, press Ctrl + Shift + Esc.
- If Task Manager flickers too, the problem is probably the display driver.
- If Task Manager does not flicker, but the rest of the screen does, the problem is probably an incompatible app.
- If it points to the display driver, fix it in Device Manager.
- In the taskbar search box, type device manager and open it.
- Expand Display adapters.
If this started after a recent Windows Update, try Roll Back Driver:
- Right-click the display adapter > Properties > Driver tab > Roll Back Driver > Yes.
- Restart the device.
- Note: administrator privileges are required. If Roll Back Driver is unavailable, there is no previous driver to return to.
If rollback is not available or does not help, try Update driver:
- Right-click the adapter > Update driver.
- The PC or display adapter manufacturer may have the most recent driver for the system.
If the issue continues, try Uninstall Device:
- Right-click the adapter > Properties > Driver tab > Uninstall Device.
- Select the checkbox to remove/delete the driver software for the device, then select OK.
- Restart the device so Windows attempts to reinstall the driver.
- Note: this requires administrator privileges. If the checkbox is missing, start the PC in safe mode first.
- If Task Manager does not flicker, remove the incompatible app.
- In Windows 10, go to Start > Settings > Apps > Apps & features.
- Select the app, then Uninstall > Uninstall.
- Restart after uninstalling the first app and test again.
- If the issue remains, uninstall suspect apps one by one until the blinking stops.
- If the app came from Microsoft Store, check for updates there first. Otherwise, get updates from the app manufacturer.
- If the screen is too unstable to follow the steps, start the PC in safe mode and then perform the driver uninstall or app removal.
If this began right after a recent update and Explorer keeps crashing, uninstalling the latest quality update from Windows Recovery Environment or using System Restore to return to an earlier restore point is also a supported path.
