My computer is turning on by itself?

I'm running Windows 10 on a Lenovo computer: 1TB HDD, 12GB, AMD A10.
At first, I was putting my computer in sleep mode when I wasn't using it. I noticed that every now and then the screen would turn on. I assumed every time that something had slightly moved the mouse (dryer shaking the floor from next room, someone walking by the desk, etc), so I chose to shut it down. The computer is on a desk that sits right underneath my TV, so while watching the screen, I can easily notice the computer do something. About a half an hour, maybe a bit more, went by after I had shut it down and I watched as the computer powered itself back on.
Is this some kind of virus, motherboard issue, or common thing with Lenovo desktops? I'm seriously freaked out (though I know there's got to be some kind of explanation) and I've resorted to unplugging the tower after I shut it down, which is a hassle because of the location of the desk.

How I can mute a game when I minimize it to do something else like search the web?

Why is my monitor causing the blue screen of death?

Hi, I have a Lenovo desktop computer and a Lenovo monitor. For some reason it is causing my computer to blue screen and the blue screen message says "Thread stuck in device driver". I'm certain it is my monitor because occasionally when I look at connected devices and it will say "Driver error" under it. Also sometimes it can't say what the name is for some reason. Like sometimes it says the name of the monitor other times it just says Generic PVP Monitor. What is the problem?! It crashes sometime up to 4 times a day and it is annoying.
