Laptop Screen Glitching out

[u/Responsible-Sun-7987]

My Dell g5 15 5500 gaming laptop is 5yrs old and Ive never had screen issues or ever abused it, but a year ago+ I would take my laptop apart like twice a year each year but never had issues since. My screen constantly has a gray bar thats moving and glitching when I open chrome and when I close it, it stays and gets worse. Any suggestions to fix this? Ive updated my drivers and tried resetting my integrated gpu and main gpu.

Heres what it looks like, it flashes and statics only on the bottom part of the screen.
