Screen goes Black. A small box appears in the upper left corner then the screen returns

Screen goes Black. A small box appears in the upper left corner, with a few symbols inside, then the screen returns. Sometimes I have to right click and refresh. This happens most commonly when I exit the internet or when I am using the vertical scroll bar. It will lock up and the screen goes to black. This started after a recent update. the only change I noticed was the addition of a new icon, in the upper right corner next to the Favorites Icon, for the Edge Secure Network. Any guidance I receive would be greatly appreciated.

@Rotam7, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Based on your description, the issue with your HP Envy x360 16-ac0000 laptop, where the screen goes black and shows a small box with symbols seems to be related to a graphics driver glitch or display setting conflict, possibly triggered by a recent Windows or Edge Secure Network update.

Here are some steps to help resolve this:

Update Graphics Drivers

Outdated or corrupted graphics drivers can cause display issues.

• Visit the official HP driver page for your model:
  HP Envy x360 16-ac0000 Drivers
• Download and install the latest Intel or AMD graphics driver listed.
• Restart your laptop after installation.

Use HP Support Assistant

HP Support Assistant can automatically detect and install updates.

• Download or open HP Support Assistant: HP Support Assistant | HP® Support
• Run a full system check and install all recommended updates, including BIOS and chipset.

Disable Edge Secure Network (Temporary Test)

Since the issue started after this appeared, test if disabling it helps:

• Open Microsoft Edge.
• Click the Edge Secure Network icon (shield) in the top-right.
• Turn off the feature temporarily and observe if the issue persists.

Perform a Hard Reset

This can clear temporary glitches.

• Shut down the laptop.
• Disconnect the power adapter and all peripherals.
• Press and hold the Power button for 15 seconds.
• Reconnect power and turn it on.

Check Display Settings

Sometimes resolution or refresh rate mismatches can cause flickering or black screens.

• Right-click on desktop → Display settings.
• Ensure resolution is set to Recommended.
• Click Advanced display settings → Check refresh rate (usually 60Hz).

If none of the above steps resolve the issue, consider:

• Connecting an external monitor to test if the issue is with the internal display.
• Running Windows System File Checker:
  • Open Command Prompt as Admin.
  • Run: sfc /scannow

I hope this helps. 

Take care and have a good day.
