In terms of keyboard shortcuts (Assuming you're wanting to say, "Press [this] to do something cool!" User presses, and computer shuts down), there is no such default shortcut to completely turn off the computer; put it in standby or hibernation mode; or restart (Except for the power button, which on some computers, may achieve the desired effect. Power buttons can be, and sometimes are, designed differently for different company's computers.)
Shut down physically turns off your computer (If your computer supports it) Log off Logs off the current user in a multi user environment such as a school or office.
Turn the computer off then turn the computer back on
The hard drive.
Hope this is what you are looking for. My customers get very frustrated when the menu goes for a bunk so First one is easy to solve. I've seen this happen when the menu suddenly become invisible because it has been pushed down too far. The menu is adjustable and it can be accidently adjusted. Try this first: move your mouse to the bottom of the screen - the very bottom. Sometimes the arrow key will change to double headed cursor. This means the menu has been squished down. While the cursor has the double arrows, hold the left mouse button down and drag up slowly. Drag until you see your missing menu bar then let go. I find just shutting the computer off, using the off button on the case and then turning it back on again normally resolves the problem if the first trick doesn't work. To turn off your computer, hold the off button in for about 10 seconds and it should power down the computer. When windows comes back up, the menu should be back to normal. I generally don't recommend people use the off bottom like this, but sometimes you can't get around it. If these steps don't work you may have a virus or parasite (similar but not quite the same). Run a thorough virus scan and see if it catches anything. Also get a piece of software like Spybot's Search and Destroy http://www.safer-networking.org/index2.html install it and run it. It will take awhile but if anything is there, it will find and eliminate it. Try these steps before resorting to a complete reinstallation of your OS. Hopefully one of them will work.

A computer can not turn off by itself. The monitor just turns blank it you leave it. To turn off the computer you have to prees the on button on your computer. If you press the botton on the monitor it is not turning the computer off... just the screen.
No, use the power button to turn off your computer. USB is best because You can unplug and plug the keyboard back in without your computer turning off.
That on/off trick makes it sound like a computer component and/or the oxygen sensor.
A power cycle is turning off and turning back on any electronic device.
Do it would be the general way forward. To prevent this happeneing again. Make sure that you are turning the computer off from the windows start icon in the lower left corner. Do NOT turn off the power to the computer from the mains. Refrain from turning off the computer from the power button
Logging of your computer is just turning off your particular account so someone can go on a different account. Turning off is turning off the whole system. This way, someone would have to restart the computer before they could then log on to their own account.
