Windows 10: Laptop freezes and screen glitches

Hello, I bought a used laptop at the start of February. usually in my country it's better to buy used laptops that are from other countries because we barely have originals, most of the laptops are fake and overpriced so it's normal to buy it used.I had a problem with the screen glitching and freezing, and then one day the computer shut off completely. I took it to get fixed, and they said there was a problem with the hard drive motherboard. They fixed it, and I got it back May 10th. a few days ago I noticed a small glitch again, but it was nothing. Today, it lagged the same way it used

glitching screen and glitching videos

Hello,

Recently my laptop screen started to freckle\glitch while playing videos either on the internet or on my laptop so I followed steps suggested as to uninstall and re-install the graphics update however, it happened again not so long after I did that (1 day later) and I fixed the display and so it stopped but the videos appear to be glitched? like I could see the RGB (there is a color stroke that appears ONLY while watching videos and I tried to take a screenshot and while trying to trim the photo I found it looking normal so it's only via videos

I'm using HP ENVY Laptop - DESKTOP -LUQEG7V

 

Looking for help with laptop screen

It's quite easy to replace a screen, try to find a disassembly guide for the specific model of laptop so you have a step by step indication of where to take screws out and what clips to unclip. There might be some youtube videos as well. Always make sure the replacement screen is compatible as there can be different connectors.
