This is almost certainly an indication of failing video hardware -- either the screen or the video chip or both.

You need to connect an external monitor to the laptop.

If the visual artifacts also appear on the monitor, then it is a failing video chip and since those are soldered to the motherboard, they are not replaceable.

If the vistual artifacts do NOT appear on the monitor, then it is a failing laptop screen. While those can be replaced, the cost varies enormously by individual PC model.

We are not able, or permitted, to provide any repair estimates or equipment prices.
For this information, you would need to contact an HP Repair or Service Center.

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

Good Luck

Hi Sir. I connected an external monitor to the laptop. But the visual artifacts did not appear on the monitor. Can I fix it via "ROLL BACK DRIVER" and a BIOS UPDATE or WINDOWS UPDATE? Thanks for your response.

As I already mentioned, the artifacts not appearing on the monitor means it is the laptop screen and since the visual artifact is a hardware problem and all the solutions you propose are software, none of them are going to fix this.
