You can also press and hold the power button on most Windows PCs to bring up a shutdown option.

Your computer's moving parts, like hard drives HDDs, might wear out faster with constant use. Prolonged use can lead to heat buildup and overheating, potentially affecting the lifespan of components like the CPU and GPU—parts that could be costly to repair or replace.

Some say leaving a computer on all the time saves wear and tear on the components. While frequent restarts do cause more wear on components, it's fine to shut your machine down daily.

The very first step is to turn on the computer. To do this, locate and press the power button. It's in a different place on every computer, but it will have the universal power button symbol (shown below). Once turned on, your computer takes time before it's ready to use.

“It depends on how often you use it,” explains Geek Squad agent Steven Leslie. “If you use your computer multiple times per day, it's best to leave it on. If you use it for a short time — say an hour or two — just once a day, or even less, then turn it off.”

A surge protector provides considerable protection against this danger; however, the only way to ensure that a power surge will not damage your computer is to turn off the computer and unplug it.

Hibernate uses less power than sleep and when you start up the PC again, you're back to where you left off (though not as fast as sleep).

A typical PC consumes something like 300 watts. Let's assume that you use your PC for four hours every day, so the other 20 hours it is on would be wasted energy. If electricity costs 10 cents per kilowatt-hour in your area, then that 20 hours represents 60 cents a day. Sixty cents a day adds up to $219 per year.

Therefore, you should leave the computer turned off when you do not plan on using it for a fairly long time or when lightning is in the area. Power consumption is also a consideration.
