Blue screen and restart Windows The Windows blue screen is one of the bogeymen for anyone who has been using computers for a few years: at least once in our computing life we ​​will have seen the dreaded blue screen error.

In this scenario, Windows does not want to start or finish the operation we were carrying out (since it can appear suddenly even during work), leaving us with a sense of frustration and discouragement.

In the following guide we will show you how to remove blue screens, errors and unexpected restarts of windowsso you can get back to work on your PC worry-free.

1) The computer shuts down suddenly after turning it on

Often this problem is caused by the hardware, i.e. a problem with the components inside the PC; in most cases it concerns the power supply unit (PSU) the component that supplies energy to everything.

Change the power supply it’s simple and it’s cheap: if you’re good at working with electronic parts, it can even be done at home without involving a technician. If changing the power supply does not solve the problem, it could be the motherboard that is damaged.

In this case it is highly recommended to contact an expert technician, so that he can repair or change the PC motherboard, even if we can try the replacement at home by reading the advice in the guide on how to change motherboard.

Still on the sudden shutdown of the PC we can read the guide on what to do if your pc shuts down by itself.

2) A blue window appears at startup or during use

The blue window can depend on many factors, but a good starting point is the error code shown in the window itself.

We read the error code, write it down and look for it on How2do: we dealt many famous error codes and often it takes very little to find a solution.

Alternatively, we can always search for the code on Google, so as to obtain information on the nature of the problem (be it hardware or software). The main causes of blue screens are:

  • Faulty drivers
  • Drivers out of date
  • Faulty Windows Updates
  • Corrupt video card drivers
  • Damaged RAM
  • Hard disk failing

Let’s read all the guides proposed, so that we can find a solution to all the most frequent blue screens on Windows. On the same subject we can read the guide on how to fix windows crashes.

3) The laptop shuts down by itself, without showing a blue screen

Given that sudden shutdown without error screens is always a hardware problem, if the laptop shuts down by itself during busy work or in the middle of summer, in most cases we are victims of the processor overheating.

Overheating in a laptop is often caused by dust-clogged vents; another cause of this error (rarer) can be the failure of the temperature sensors. In this case the computer does not understand if there is too much heat and, to be safe, it shuts down.

First let’s try to clean laptop fansby removing the buildup with a can of compressed air. After cleaning we start the PC, download a program to monitor temperatures such as SpeedFan and we run a heavy program to check for sudden shutdown.

If the problem is not solved, unfortunately, all that remains is to change the CPU and its cooling system, a rather expensive and almost impossible operation on modern notebooks with a single body (Unibody).

4) Various blue screens are shown, with many errors

If we are literally invaded by blue screens and they are random (without a precise order), the Windows system is now compromised and it is advisable to restore it as soon as possible, so as to return to using the PC normally.

First, it is always advisable to start the PC in Safe modeTherefore use restore points to try to go back to a date before the problems appeared.

If the restore points do not work, are not present or can not be accessed even in safe we ​​can use a system image on windows for restore, but only if we created that image before the problems started.

As a last resort we can always start the clean install recovery procedure of Windows, able to save even personal files and make Windows like new again.

PC won’t boot anymore and can’t access the recovery console? Let’s create one USB stick with Windowsformat the whole disk and start from scratch, saving personal files with a Linux distribution (to be started before formatting).

To learn more, we can read our guide on how to format and install windows from scratch.


In conclusion, we remind you that if the PC shuts down by itself, it restarts suddenly or shows the blue screen it is always advisable to first identify a possible hardware error (RAM, disk or power) and only then focus on the drivers and the operating system.

In general, to understand what the blue screen error is, I recommend reading the guide for theanalysis of Windows “blue screen” crashes and look for the cause of failure.
