I was just reading a powerpoint then suddenly my screen started flickering with green lines. How do i fix this, please help.

My laptop screen is flickering pink and green lines

My laptop screen is flickering pink and green lines. I've already updated the driver. I tried connecting it to an external monitor using HDMI cable and it works fine. The flashing lines also appear when I access the bios. Does anyone know how to fix this? I'm using acer aspire 5 btw. Thanks.

 

A green line keeps on flickering my laptop screen.

I was casually using my laptop when a green line appeared on my display. For a few minutes, it started to flicker causing my display monitor to flicker colors like green, cyan, and blue. I tried to roll back my driver but it's still there. I know this is a minor problem, but it's literally annoying me.

Here's the specs of my laptop:

Device name Compact-Racer-B01

Processor AMD Ryzen 5 4500U with Radeon Graphics 2.38 GHz

Installed RAM 12.0 GB (11.4 GB usable)

Device ID 517C1FE4-3343-46B8-9696-5C52571A3240

Product ID 00327-30871-34932-AAOEM

Edit:

I noticed that my fan is a little bit dusty. That may be the root cause of the green flickering?

 

There is a green line in my screen ....

There is this green line unexpectedly appeared on my screen. I've tried multiple ways to get rid of it but, it didn't work for me. I am aware that I might have to get a screen replacement but I'm currently unable to do it... The green line appears even when starting the laptop in the logo screen. Please suggest any way to fix this issue! However I've tried to include a screenshot, but the green line doesn't appear there?
