Sometimes the computer does not start or turn it on again. There are several reasons that can cause this judgment and do not start Windows.

Computer1. Check if you have really turned the PC

Often a PC will not start for the simple reason that they have not really come on. Do these checks:

You press the power button. Perhaps you not pressed before all or hard enough.
Many power supplies or have their own power switch. Usually in the back in the fixed PC, at source. Make sure it is on before booting the PC.
Your computer is plugged into a power strip, extension or electrical thief? Or a Uninterruptible Power Supply (UPS / UPS)? Or in any other manner other than directly into the wall socket? If so, verify that these intermediate systems are turned on and connected.

2. Check cables

Or disconnected cables have loosened are another very common reason that the PC can not be turned on. Check:

In fixed equipment. Cable connection in the power supply and wall.
Portable laptops. PC connection to the wall and to the transformer it (square or rectangular device between the power outlet and the computer).
Connections to power strips, UPS, etc. And those systems to the main outlet on the wall.

3. Is there power?

Clearly, the PC will not work if the power failure for any reason whatsoever. Shine a light to verify that there has been a general court. If there is light, perhaps this evil wall outlet, power strip, UPS, etc.

The easiest way to check is by connecting a lamp, a cassette player or other device that you know is able. If that does not work you know that there’s the rub. You’ll have to fix the wall socket (use another meanwhile), change the strip, UPS or whatever.

4. Check the voltage

The grid of each country uses a certain voltage.
Most are normal 220/230 V, common in Europe, or 110/115/120, used in the United States and several other Latin American countries. Check out this list to find out the voltage in the country where you are.
Some power supplies have a switch or something to change it. Usually 110/115 220/230 V to V or vice versa. Check that is correct.

Improper voltage may harm your computer permanently. Especially if you use one that allows more of your power supply. Keep this in mind especially if you plan to connect your PC in a country different from yours. Their voltage may differ. You may need a transformer to give the proper voltage.

5. Wait a while and then turning the computer

Keep this solution only if the PC has already been on recently but will not start now. The reason may be an overheating of the CPU or other hardware. It is normal that the team does not start in that case as a way to protect (or boot and turns itself off).
