HP ProBook 430 G7 Screen turning black every second.

hi ThisMyHPProBookAndHPElitebook​ Ideally you should contact hp support or windows contact. Here with I am sharing my earlier similar experience.

On HP ProBook 430 G7 laptops, this kind of black screen flicker especially after a fresh Windows 11 install is almost always related to the graphics driver or display pipeline, not a hardware defect.

Here are the steps , you can try

1) Boot into Safe Mode first

This helps isolate if the flickering is driver related:

Hold Shift → Restart

Choose Troubleshoot → Advanced options → Startup Settings

Press 4 to enter Safe Mode

If the screen is stable in Safe Mode → this confirms a driver/adapter issue.

2) Uninstall the Display Driver

In Safe Mode, open Device Manager

Win + X → Device Manager

Expand Display adapters

Right-click Intel UHD Graphics → Uninstall device

Check “Delete the driver software for this device”

Restart normally

Windows will load a basic display driver. This often stops the flickering immediately.

3) Install the RIGHT driver from HP

Do not use generic drivers from Windows Update or Intel’s site — they often cause flickering on HP laptops.

Official HP drivers (most reliable):

https://support.hp.com/us-en/drivers

Search for:

Model: HP ProBook 430 G7

OS: Windows 11

Install:

Intel Graphics driver

Optional: Chipset / BIOS updates

Restart after install.

Quick fixes worth trying

Win + Ctrl + Shift + B - refreshes the graphics stack

Disable Adaptive brightness

Settings → System → Display → turn off

If flicker only happens after login, try booting with External monitor connected to rule out panel issues
