Laptop keeps hanging?

My Terra laptop hangs every half an hour so the screen keeps freezing. Then I have to start it at it works again but only for about half an hour. Maybe one of you knows what you can do there.

Well, you first have to write what kind of laptop you have, which model etc. And which operating system is running on it. Otherwise it will be a guessing game.

Terra, the model is Mobile 1514, is at least on the floor

Which operating system?

Where can you see that?

Could that be this?: 64-bit operating system, x64-based processor

No, that's the processor, the brain of the PC.
I mean e.g. Windows, Linux etc.

An operating system is, for example, Windoof 10 or Windoof 8 or Ubuntu or Linux Mint or a MacOS

Then this is Windows 10

I would recommend you to save all important data, such as pictures, videos, programs etc. And then reset Windows 10 under Settings under "Restore".

You can start the laptop and look in the system settings, which graphics card you have and what system temperature it has. Watch your system temperature from the processor, for example. It may become too hot and then hang and restart.
