- Product
- Microsoft Word
- Device & OS
- Windows 11 (ASUS Zenbook)
- Scenario
- Using Microsoft Word for document editing on an ASUS Zenbook laptop.
- Observed behavior

Update ASUS Drivers, BIOS, and Windows System
Outdated system drivers or BIOS on ASUS Zenbooks are a primary cause of graphical glitches and unexpected authentication loops in Office applications.
Keeping your system firmware and graphics drivers up to date ensures compatibility with hardware acceleration features used by Microsoft Office.
Go to Windows Settings > Windows Update. Click 'Check for updates' and install all available updates, paying special attention to 'Optional Updates' which often contain driver patches.
Open the MyASUS application on your Zenbook. Navigate to 'Customer Support' > 'Live Update' and install the latest graphics, chipset, and device drivers.
Visit the official ASUS Support website, enter your Zenbook model, and download the latest BIOS firmware. Follow the provided ASUS instructions to flash the new BIOS safely.
Reboot your ASUS Zenbook to ensure all system, driver, and Windows Hello updates are fully applied before opening Word again.

Frequently Asked Questions
Why does Microsoft Word suddenly turn black on my ASUS laptop?
A black screen in Word is typically caused by outdated graphics drivers, conflicts with hardware acceleration, or corrupted Office installation files. On ASUS laptops, specific BIOS or chipset driver bugs can also trigger this display failure.
How do I fix Windows Hello repeatedly asking for sign-in in Word?
This authentication loop often happens when your Microsoft account credentials are out of sync or there are Trusted Platform Module (TPM) conflicts. Updating your BIOS via the MyASUS app and running an Office Online Repair usually resolves the sign-in loop.
Does WPS Office crash less frequently on Windows 11?
WPS Office is designed to be exceptionally lightweight and highly optimized for modern Windows operating systems. This often results in smoother performance and fewer graphical glitches compared to heavier office suites.
Will I lose my documents if I reinstall Microsoft Office?
No, uninstalling or reinstalling Microsoft Office only removes the application files. Your personal documents, spreadsheets, and presentations saved locally on your hard drive or in OneDrive will remain completely untouched.
