Screen flashing radnomly

[3brad]

I have only recently purchased this laptop (less than 2 weeks old), and the screen has started to randomly flash/glitch. All updates have been done and I have checked to see if the task manager flashes and it does. 

I have restarted the computer and pressed F10  repeatably to bring up the alternate menu.

How do i go about fixing this.

@3brad Welcome to HP Community!

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, this could be a hardware malfunction.

Let me know how that pans out,
