Dear Faolan,

Greetings, this is ASRock TSD.


According to your question, we provide some suggestions to verify:

1. Please refer to user manual page.30 to clear CMOS.

3. Uninstall the graphics driver from Control Panel>Program or Device Manager, using Windows 10 inbox driver to verify.

4. Reinstall AMD all in 1 with VGA driver.
