My screen keeps flashing completely black every few seconds

[Whitewulf]

While I'm sitting here with a few apps open (Opened apps: Google, discord, Autodesk Sketchbook, and Battle.net) -Side note: I've never had ANY issues with these apps before this, or on any other system- my screen starts flashing black every few seconds. It goes away for a few minutes if I restart my HP Notebook but goes back to plashing. I need to know how to fix it. I tried closing windows and everything but it won't stop the flashing every 3-20 seconds, so I need to know what I should do about this.

Welcome to HP support community.

Provide the computer model number or the product number?

Meanwhile:

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure, 

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer, 

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here 

  

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link, 
If it does, you may need to replace the LCD/Repair the computer.

Let me know how it goes.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
