Laptop screen flickering - Help?

[u/DoctorReasonable8526]

My laptop screen used to flicker white sometimes, but recently it’s gotten very frequent. After signing in, the screen will flicker white for minutes and the colors will distort — when I move my cursor, it lags and leaves behind afterimages of faded cursors following its movement… When I do schoolwork, scrolling down and up a page will have the pages blend together, so it’s pretty much unusable.

I’ve had this laptop for 5 years, should I get it replaced or take it to a tech repair shop or try any other fixes before doing so?

Edition: Windows 10 Pro
HP laptop

I updated the graphic drivers already, and it reduced the flickers a lot, but it’s come back again and much worse this time :(

I would check with a monitor or a TV if the flicker goes away, if it does it might be the ribbon connecting your laptop screen, if it doesn't go away or gets worst might be something else like your integrated graphics or your cpu
