G9-791 - Random black screens instead of desktop, sometimes laptop doesn't start at first boot

Ok, so this comes by again and again, I can't get pass through it. Basically, not every bootup, but most of them, I see :
1. I open the lid and click power button
2. Predator screen will be backlited, and predator logo shown
3. Predator logo goes away, screen stays black
4. Fans slow down, diods stop blinking, power button and keyboard stay lit.
5. Laptop is unresponsive.

At that point I have to hold power button until full power off. I I won't be waiting long enough, it will go into standby mode, with power button bliking, but clicking it ON again, won't help, it will get off standby, just to get me back to black screen agian.

Sometimes I do :
1. I open the lid and click power button
2. Predator screen will be backlited, and predator logo shown
3. In the bottom of Predator logo little Windows doted circle appears,my login screen is shown
4. Fans slow down, diods stop blinking, power button and keyboard stay lit and I'm on desktop.
5. Laptop is fully ok and functional.

Does anyone else face same issue? I belive it's Windows 10 reletaed, as this started hald a year ago.

Also sometimes when I try to reboot it forcefully with a button, it will show me in white on blue manner (like old BIOS or windows installation)
that there aren't any boot disk plugged it, (almost like I would unplug SSD). To get rid of this I have to once again forcefully reboot it, and than it usually goes away.

I get this behaviour constanly...... What is this? Is this Nvidia Optimus releated? Something wrong with GPU or what?
On heavy load laptop stays fully operational. RAM and SSD's are fully functionall aswell. If it works it works 100%. If it won't boot it just won't.

I want to sell this laptop and get Asus

As long as you're selling it, I suggest that you simply re-set the machine to a factory-fresh state which will either rule out or rule in a hardware issue. Jack E/NJ
