Edge Login Flicker Resolved: GPU Driver Corruption Case Study

Question

Issue: 

On my desktop PC, I was unable to log into my Microsoft Hotmail account using Edge. The password field flickered and wouldn’t accept typing or pasting. The issue worsened over time, suggesting a driver-level fault.

 

Symptoms: 

• Login screen loads, but password box flickers and blocks input 
• No keyboard or mouse input accepted 
• Issue isolated to desktop; laptop login works fine 
• Affects Microsoft Edge (latest build)

 

Troubleshooting Steps Taken: 

• Ran sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth
• Reset Edge settings, disabled extensions 
• Deleted Edge’s user data folder 
• Changed graphics settings to force high-performance GPU usage 
• Disabled hardware acceleration 
• Verified no failing hardware (RAM, SSD, GPU all stable)

 

Resolution: 

• Booted into Safe Mode 
• Used Display Driver Uninstaller (DDU) to fully remove NVIDIA drivers 
• Disconnected from internet to prevent auto-install 
• Reinstalled WHQL-certified NVIDIA driver 475.14 for GeForce GTX 760 
• Rebooted and tested login—issue resolved immediately

 

Conclusion: 

Corrupted graphics driver stack was interfering with browser-based input rendering. Reinstalling the correct driver restored full functionality.

 

System Info: 

• OS: Windows 10 x64 
• GPU: NVIDIA GeForce GTX 760 
• Driver: 475.14 WHQL 
• Browser: Microsoft Edge (latest build)

 

Note: 

If you're seeing flickering login boxes or blocked input in Edge, don’t overlook your GPU drivers—even if everything else seems fine.
