Until some time ago the "blue screen" was usual, today it is certainly less frequent but this does not mean that Windows does not crash the same, every now and then. There are several ways in which the PC crashes or freezes : the sudden blue screen, a continuous restart or an interrupted startup, the frozen screen (freeze) with the mouse that no longer moves, the normal sudden restart without any indication . You don't have to blame Microsoft and the answer to the problems is not to switch to Linux or Mac. Windows is a complex operating system that is designed to work best on any computer where it is installed (while the Mac OSX system is installed only on Macs) therefore it may happen that, under particular circumstances, it malfunctions. Let's see the 10 main reasons for Windows crashes so as to better understand what happens when the blue screen appears, when it restarts on its own or when everything freezes .

1) Fatal error of memory or motherboard
A frequent reason for the blue screen (also called BSOD or Blue Screen of Death)
it's a RAM or motherboard problem.
In practice, the data that must be saved in the memory cannot be recovered by the processor and an inconsistency is created that the computer cannot manage.
You can check whether the memory is intact with a program such as Memtest86 or, in some cases, using the motherboard diagnostic tool if it has been provided.
Another way to check that RAM is not broken is to obviously change it to a new one and see if the problem goes away.
On the other hand, it is very difficult to understand if the problem is with the PC motherboard.
If all the reasons for this article can be excluded, then it is the motherboard that is ruined and all that remains is to change the computer.
Some ways to fix blue screen issues, shutdown or sudden restart of computer are in another article.
2) BIOS settings
Most motherboards leave the factory with configuration settings compatible with any hardware.
These settings can be changed by whoever sells the PC and problems may arise.
In another article, the guide to do a BIOS reset by clearing the CMOS memory.
Another common problem, especially in the case where the computer starts very slowly, is the boot order which puts the USB port or CD as the first choice.
So if you leave a USB stick connected to the PC, and in the BIOS the boot from USB is set as the first option, the PC searches for an operating system in the stick and, finding nothing, it stops.
Enter the BIOS and change the boot order of the computer by replacing the hard disk, called HDD, as the first choice.
3) Registry damaged
The Windows Registry no longer has the problems it had in the past, but it can still be ruined by some programs or old viruses.
A corrupt registry is primarily responsible for computer crashes or correct and quick startup.
To solve the problems, start the pc in safe mode and clean the registry with ccleaner or other programs.
4) Damaged, wrong or outdated drivers
The main reason for the Windows crash or freeze freezes on the computer is certainly related to the drivers.
The hardware drivers tell the operating system what it has to do with the components from which the PC is formed: audio, video, printer, mouse, keyboard, etc.
If they don't work properly, the computer doesn't understand what to do with a device and crashes.
Crashes of this type are generally associated with an error message indicating the name of the offending hardware.
If not, try searching for the message through Google to see if it finds the culprit.
If possible, try using the computer with all external devices disconnected and selectively see if the fault is one of them.
Update your PC drivers, and, if the problem persists, try to uninstall the drivers completely and reinstall them from scratch.

5) Hard disk problems
Unfortunately, the hard disk is the part of the computer that is damaged most quickly.
A hard drive failure or even a small sector is one of the main causes of Windows startup problems or crashes.
In severe cases, when the computer loses its ability to find the boot drive and therefore the main disk where Windows is installed, after checking that the BIOS is configured correctly (see point 2), then it is a problem of hard drives to be changed or repaired.
If you are still able to boot your computer, try using the in-depth scandisk to scan for disk errors and then do a hard disk integrity check.
If the disc doesn't boot right, you need to reinstall Windows to a new hard drive.
After everything works, you can connect the old hard drive as a secondary one to recover the files and bring them back to the new one.
6) Hardware conflicts
Windows sometimes crashes if you get contradictory information from various pieces of hardware.
This is a type of generally random block that you shouldn't worry too much about unless they are frequent.
If there is a hardware conflict, open the Device Manager and check if there are icons with the yellow exclamation mark.
You can then update the driver or disable that component to bring the situation back to normal.
7) Virus or Trojan
Even today, a virus or malware can cause serious damage to your PC and cause malfunctions.
Malicious software may damage or remove drivers, delete important system files or modify administrative settings.
There are those who think that it is not worth fighting against viruses when they have already ruined everything, but one should never lose heart and, before formatting everything, some paths can be tried.
SEE: How to remove viruses and malware .
8) Power problems
A computer crashes and crashes and restarts suddenly in the event of a power surge or sudden power failure.
A problem with the internal power supply reduces the power it can provide, or causes an uneven flow of power, which can cause crashes (replace the power supply).
If instead there is a power problem at home, the advice is to have a UPS unit that acts as a battery for the computer.
Obviously check that the power socket, the power cable or the power strip are intact.

9) Software Reasons
Most program errors do not cause Windows to crash unless the program is heavily exploiting a hardware component.
For example, heavy software such as video games that make full use of computer graphics cards can crash due to this intense use of hardware capabilities.
In rare cases the PC may freeze on startup due to software that starts automatically.
This type of problem can be solved by starting in safe mode (see point 3) and using msconfig to disable programs that start automatically.
10) Overheating
In computers there are sensors to detect the temperature.
If too high a temperature is detected, especially on laptops, the computer shuts down to protect the integrity of the hardware before permanent damage.
Overheating occurs especially in summer, when it is very hot.
In rare cases, he may understand that the sensors break and that the computer turns itself off after a short time it is turned on.
An acoustic signal at the time of the crash could be a signal indicating processor overheating.
If there is a problem of insufficient ventilation, in another article 8 ways to cool the pc in hot weather are described.
This list should provide a nice summary of the main causes of Windows crashes and serious errors on computers.
There are times that solving is difficult and technician intervention is required, while other times it is absolutely possible to repair the computer without going to the technician.
