How to Fix a Computer That Won't Turn On
It's a really awful way to start a day: you press the power button on your computer and nothing happens.
There are many reasons why a computer won't turn on and often very few clues about what might be the problem. The only symptom is usually the simple fact that "nothing works," which isn't much to go on.

Read the first section below (it'll make you feel better).
Pick the best troubleshooting guide from below based on how your computer is acting or choose the last one if your PC stops at any point because of an error message.
The "computer won't start" troubleshooting guides below apply to all PC devices. In other words, they'll help if your desktop or laptop won't turn on, or even if your tablet won't turn on. We'll call out any important differences along the way.
Also, all techniques are applicable no matter what Windows operating system you have installed on your hard drive, including Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP. The first five steps even apply to other PC operating systems like Linux.

Your Files Are Probably OK
Most people tend to panic when faced with a computer that won't start, worried that all their precious data is gone forever.
It's true that the most common reason a computer won't start is because a piece of hardware has failed or is causing a problem, but that hardware isn't usually a hard drive, the part of your computer that stores all of your files.
In other words, your music, documents, emails, and videos are probably safe—they're just not accessible at the moment.

Try these steps if your computer will not turn on and is showing no sign at all of receiving power—no fans running and no lights on the laptop or tablet, nor on the front of the computer's case if you're using a desktop.

Here's What to Do When Your Computer Has No Power
Don't worry about the monitor yet, assuming you're using a desktop or an external display. If the computer won't on because of a power-supply problem, the monitor certainly can't display anything from the computer. Your monitor light will likely be amber/yellow if your computer has stopped sending information to it.

Computer Powers On and Then Off

Follow these steps if, when you turn your computer on, it promptly powers back off.
Here's What to Do When Your Computer Shuts Off During Startup
You'll probably hear the fans inside your computer turn on, see some or all of the lights on your computer turn on or flash, and then it will all stop.
You won't see anything on the screen and you may or may not hear beeps coming from the computer before it shuts off by itself.
Like in the previous scenario, don't worry about the state your external monitor is in, if you have one. You may have a monitor problem as well but it's not possible to troubleshoot it quite yet.

If your computer seems to be receiving power after turning it on but you don't see anything on the screen, try these troubleshooting steps.
Here's What to Do When Your Computer Starts but Nothing Happens
In these situations, the power lights will stay on, you'll likely hear the fans inside your computer running (assuming it has any), and you may or may not hear one or more beeps coming from the computer.
This situation is probably the most common in our experience working with computers that won't start. Unfortunately it's also one of the most difficult to troubleshoot.

Windows Begins to Load but Stops or Reboots on a BSOD
Screnshot of a 0x5C / HAL_INITIALIZATION_FAILED Blue Screen of Death (BSOD) in Windows 8
If your computer begins to load Windows but then stops and displays a blue screen with information on it, then try these steps. You may or may not see the Windows splash screen before the blue screen appears.
How to Fix a Blue Screen of Death
This kind of error is called a STOP error but is more commonly referred to as a Blue Screen of Death, or a BSOD. Receiving a BSOD error is a common reason why a computer won't turn on.
Choose this troubleshooting guide even if the BSOD flashes on screen and your computer restarts automatically without giving you time to read what it says.
