Laptop freezes when watching YouTube in full screen?

A few days ago it happened to me every day. When I look at YouTube and go full screen everything is normal, but when I leave full screen mode, the whole laptop freezes (not always just sometimes) and it only helps to push the power button. Is there a reason why this happens and can you fix it? (I only use Google Chrome, I do not know if that happens with other browsers)

Then just try other browsers. So you can limit the source of error if necessary Schonmal.

Since I would first check the driver for your GPU and update if necessary.

It is also important to check if the whole thing happens in another browser.
