Reoccurring black screen on HP Omnistudio x 31.5 inch all in one pc.

[Kevdenn]

When I turn on the PC the computer boots but the screen flashes on for about 1 seconds then remains black. If I press CTRL-SHIFT-WINDOWS and B the screen will flash on and I can see my home screen for 1 second before it returns to black. The PC is booting but the screen stays black. Sometimes the display will work properly and I can use the pc as intended but more often the screen will remain black except for when I use the key combination, then it'll flash on the display for 1 second. The pc is under a year old. Could this be fixed under warranty?

@Kevdenn, Hello and welcome to the HP Support Community!

Thanks for posting your question. I'm here to help you get things back on track.

I understand how frustrating it must be to deal with a reoccurring black screen issue, especially on a relatively new PC. Let's walk through some steps to help resolve this and clarify warranty coverage.

Display Driver Reset (CTRL + SHIFT + WIN + B)

You're already using the shortcut correctly. This command resets the graphics driver and is useful when the display freezes or goes black temporarily. However, since the issue keeps returning, deeper troubleshooting is needed.

Update or Roll Back Display Drivers

• Press Windows + X → Select Device Manager
• Expand Display Adapters
• Right-click your graphics adapter → Choose Update driver
• If the issue started after a recent update, choose Properties → Driver tab → Click Roll Back Driver

You can also download the latest drivers from HP’s official page: Official HP® Support

Check Power Settings

• Go to Control Panel → Power Options
• Set “Turn off the display” to Never (for testing)
• Disable any sleep or hibernation settings temporarily

Run HP Diagnostics

Use HP’s built-in diagnostics to check for hardware faults: HP PC Hardware Diagnostics | HP® Support

Check for Overheating or Loose Connections

• Ensure vents are clean and unobstructed
• If comfortable, inspect internal display cable connections (or have a technician do this)

I hope the information shared has been useful and resolves your concern.

Wishing you a smooth and hassle-free experience ahead!
