Troubleshooting
If the above steps do not resolve the flickering, consider the following troubleshooting tips:

- Reset Windows: As a last resort, reset your Windows installation via Settings > Update & Security > Recovery > Reset this PC. Choose to keep or remove your files based on preference.
Frequently Asked Questions
1. Why is my Windows screen flickering randomly?
This can be caused by outdated or incompatible graphics drivers, display refresh rate issues, hardware problems, or software conflicts. Updating drivers and adjusting display settings often resolve it.
2. How do I know if my monitor or graphics card is faulty?
Test with a different monitor or cable. If flickering persists across different displays, your graphics card may be at fault. If only one monitor flickers, it might be hardware failure or connection issues.

Disabling hardware acceleration can reduce flickering in browsers and some apps, but it might impact performance. Use this as a troubleshooting step temporarily.
5. How long should I wait after changing display settings?
Wait at least 30 seconds after applying new settings to see if the flickering stops. Sometimes, a restart is necessary for changes to take effect.
6. What should I do if none of these steps work?
If the issue persists, consider consulting a professional technician or contacting your device manufacturer for hardware diagnostics and repair options.
