Hi and welcome!
Can you mention your other components?
Also... do you use the integrated GPU or external one?
It looks like gpu related problem ... does your num lock work after you lose your screen (when you press num lock does your keyboard led turns on?)?

In the video i use integrated gpu, if i use dedicated gpu the monitor just showing the last frame and then just freezing. I already check the gpu and thats not the problem. And i also check the procie, swap with different one and still not working.

Usb peripheral just lost power.
