Why is my laptop screen flickering?

Hello can someone please tell me what my laptop has?

This looks like a broken graphics chip, these are typical signs.

Start the calculator again (if you have not done that yet), if it still looks like that you have very bad cards.

Graphics chip defective.

What the ton.

Plug in an external monitor. If there the same picture then chip defective.

Do you have only one processor which also has a graphics chip or a built-in. Processor and an external graphics chip. It could also be a cable broken. But it looks like a defective processor / graphics chip. You could fix it, aver that is definitely expensive than the laptop value.

Hello Thanks for the answer so with my external screen nothing is displayed

I have an external grafikchip
