Computer Keeps Shutting Down without Going to Sleep

Okay

When I install Windows 8.1 Update, it usually changes my color. It's still green. The color is usually blue.

It's usually gray. It's still green on the background when I log in.

The start button is usually blue, it's still green.

Okay. I've got that back to normal. But, it didn't change the start button color. It's still green. Also, is there supposed to be a sign out option on the power options button on the Start Menu.

It's got more updates to install, maybe this will fix it. Let's see.

So. What do I do about that?
