@Tejveer,

Welcome to the HP Support Community!

Are you getting these black lines on all the screen? (Like desktop, browser and other applications)

I recommend you update the BIOS and the graphics driver from the below link and check if it helps.

BIOS: https://ftp.hp.com/pub/softpaq/sp93001-93500/sp93116.exe

Graphics: https://ftp.hp.com/pub/softpaq/sp74501-75000/sp74717.exe

If you continue facing the issue, I recommend you boot to BIOS by tapping the F10 key on startup and check whether the issue persists in BIOS.

Let me know how it goes and you have a great day!

Cheers!
