@dips78600, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Screen Flickering and Keyboard Issues While Gaming! 

We're thrilled to have the opportunity to assist you and provide a solution.  

Screen flickering, keyboard lockups, and display blackouts during gaming or streaming can be challenging to diagnose. Here are some steps to help resolve these issues:

1. Perform a Hard Reset

Performing a hard reset can resolve many common issues by clearing the memory and reestablishing connections between the BIOS and the hardware.

1. Turn off the computer.
2. Remove the computer from any port replicator or docking station.
3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
4. Unplug the AC adapter from the computer.
5. Press and hold the power button for at least 15 seconds to drain residual power.
6. Plug the AC adapter back into the computer, but do not connect any of the peripheral devices.
7. Press the power button to turn on the computer.
8. If a startup menu appears, use the arrow keys to select Start Windows Normally, and then press the Enter key.
9. After reconnecting each of the peripheral devices, run Windows Update and HP Support Assistant to update all device drivers.

2. Reseat Cables and Connections

Improper or loose connections can cause screen flickering and keyboard issues. Examples of reseating hardware include:

• Reseating the memory modules can resolve memory errors, no-boot, and blue screen issues.
• Reseating the storage device can resolve a POST error 3F0 (no boot device) issue.
• Reseating the keyboard cable can resolve unrecognized keys errors.
• Reseating the wireless module and antenna cable can resolve wireless connection issues.  

Hope this helps! 

Take care, and have an amazing day!

@dips78600, Thanks for hanging in there — I know how frustrating this can be, especially when your screen goes dark mid-game or while watching Netflix. Let’s try to get you back to a smooth, flicker-free experience.

Since you’ve already done the heavy lifting with driver, BIOS, and Windows updates, and even reseated components, let’s dig a little deeper:

1. Check for Overheating
While gaming or streaming, your system might be heating up more than expected. This can cause sudden black screens or input failures. Listen closely — are the fans louder or struggling? Try running a temperature monitoring tool like HWMonitor to see if the CPU or GPU temps spike before the issue hits.

2. Run HP Hardware Diagnostics (UEFI)
Let’s rule out any failing hardware:

Turn off your laptop.

Turn it back on and immediately press Esc, then F2 to enter diagnostics.

Run a System Test and especially check the Graphics and Keyboard tests.

3. Disable Fast Startup (Windows feature)
Sometimes Fast Startup interferes with graphics initialization:

Go to Control Panel > Power Options > Choose what the power button does > Change settings that are currently unavailable.

Uncheck Turn on fast startup, save, and reboot.

Hope this helps! 

Take care, and have an amazing day!
