so many questions but no solution?

No errors. Everything is fine. Also in Device Manager. No big temperatures. Everything looks fine. 

hard to say. Is it from beginning or few days after I start using notebook. Can't remeber. No, bios was older version, when the problem start, I decide to update bios, I was thinking that is the problem. Then for few days everything was good and then started again. But it is hard to saying more clearly, because this…

how enabling startup sound can fix problem? Restarts are always normally, it happens when I start computer after night. So after bigger break. But still randomly.

I dont have this option

there was already few updates, nothing changed, i think it is from beginning. I got this notebook for 2 months

It happens no matter if it is on battery or on charger. Almost always I using my notebook with connected charger.

Yeah, I disabling fast start up - nothing change, and in bios - there is no fast boot option. But what with that first option, we give up the idea of bios downgrade?

nope. Nothing. 

Before I started your instruction "POST animation and sound" was already disabled. When I restore Default settings of bios, sounds back, then I turn off pc, and then perform the reset from back of my notebook. But nothing changed. Still 1.09

I did what you said, but nothing had changed, still bios 1.09. 

Yes. This is ph517-61. Problem is that, when i trying to install bios, there is info that I already had newest update 1.09. Do I need to downgrade to 1.07? And how?
