After learning how to recover files from an external hard drive, let’s see what should you do when the Windows PC won’t boot.

Part 2: What to Do When Windows Won’t Boot

There are few things more frustrating than a computer that won’t boot up. In general, PC won’t boot is a common symptom with a variety of causes.

However, what should we do if our Windows refuses to boot? Here are a few things we can do if we encounter the Windows won’t boot issue.

1. Check Whether Something Has Been Changed

If your Windows won’t boot, the first thing you should do is to think about changes you have made with your PC recently.

Did you recently install a new hardware driver?

Did you connect a new hardware component to your computer?

Did you open your computer’s case and do something?

If the hardware driver is buggy and the new hardware is incompatible, you might encounter the Windows won’t boot issue. Or, if you accidentally unplugged something while working on your computer, your PC might stop booting. In these cases, you need to remove the drives and external devices, and check whether the cables in your computer are normally connected.

2. Check the Power Supply

In general, battery issues could be the source of your system’s inability to boot properly. This is one of the most common problems. While checking the power supply, you also should check the fuse inside the PSU itself. Remove it from your PC, and then remove the metal case to check if that’s the problem.

3. Check the Display

On the other hand, do not forget to check your computer monitor. If your computer seems to power on but your screen stays black, you should ensure your monitor is powered on and the cable connecting to your computer’s case is plugged in securely at both ends.

4. Fix Some Errors

Windows Starts and Shows a Back Screen

What should you do if your PC is powering on but you get a black screen that says something like “NTLDR Is Missing” or “Operating System not found”?

Please follow these two posts to fix the error message separately.

Have you ever heard of the blue screen of death (BSOD)? In general, most Windows users would have encountered BSOD.

For instance, for Windows 10 users, the Blue Screen of Death could appear after the update, such as a software update, driver update, and system update. As a result, their PC cannot boot. Fortunately, you can know how to solve this issue through this post: Windows 10 Blue Screen of Death – You Can Quickly Fix It.

Of course, there are other error messages you might encounter when PC won’t boot, such as Black Screen of Death, Boot Device Not Found, etc.

5. Reinstall Windows

You may be facing either a software or hardware problem if Windows seems to start booting but fails partway through.

In this case, you can try reinstalling Windows to fix this issue. However, if your PC still cannot boot after reinstalling, your PC likely has a hardware problem.


Warning: Reinstalling Windows might overwrite the original data. Thus, if you have important files stored on the dead PC, you have to get them back before reinstalling Windows (MiniTool Power Data Recovery is a good choice).
