Although these types of problems can be solved at home in many cases without having to go to a technician, it is still necessary to know what to do according to the error or the type of damage that has taken place.

A computer that slows, blocks or shows errors should not necessarily end up with a technician. With the right tools and a little patience, many problems can be solved independently, which saves time and money. So let’s look at the most important problems of the computer when it breaks and the More direct repairs for a Windows computerBoth if there is a problem with the operating system, and when something breaks into the PC or one of the pieces is defective and replaced.

In some rare cases it can also be the motherboard To be broken, but in this case you must at least hear (and see inside) that the feeder fan runs.

The computer starts but does not load Windows

There are two ways in which the PC can give the start of the computer errors: Immediately display an error or a black screen or in the event that the Windows Loading screen appears but cannot supplement, stay still or restart itself.
If the screen stays black or with an error such as “Disco is not found“Or”Operating system not found“O other types of errors that prevent Windows from loading, then there is a configuration or damage problem of the sector called Master Boot -record. In other words, there is an error at the start of the computer that can be corrected by yourself, even if it may be complicated. The problems.
We saw the entire guide to repair the computer in the event of errors at the start in the following articles:
– Repair MBR on Windows to restore Boot Loader and Computer Start
– Solve the mistake “unable to find an operating system” on Windows
– “PC solution was not started correctly” or “missing bootmgr” in Windows.

If Windows does not charge aloneThe problem can also be one Broken hard drive or damaged ram memory.
To check the ram memory Has no problems, you can download a tool with the name Memorial which must be burned on a disc and must be loaded by the PC by the CD player. Compared to the power supply, RAM and hard drive are parts of a computer that is simple enough to replace.
For more information about these DIY repairs, consult Guide to add ram memory and on the Manual to install a second internal hard drive.

Although the change in the RAM does not cause discomfort, when replacing the hard drive you have to think about the data that you probably want to recover (if you don’t have a backup on another internal or external drive).
The trick is to mount the new SATA -hard disk that has just been purchased, without removing the broken that must be made secondary.
To restore the data from the damaged hard disk you can Save everything on the new hard disk using a live CD Live.
However, the best solution is to install Windows on the new disk and then use the old disk as a secondary and transfer data.
Keep in mind that broken hard drive can cause computer blocks and blue screen errors. It is better to check the health status and the performance of the hard disk.

If the hardware is intact, the problem can be software. Start Safe mode (Press F8 or Shift+F8 at Restart) You can check whether Windows Charging. As an alternative, it is tool System file check (SFC) Repair Corrotti file:

• Open the command prompt as manager (Windows key, type “CMD”, right -click, “Perform as a manager”).
• Type sfc /scannow And press send.

If SFC is not enough, perform dism /online /cleanup-image /restorehealth Download intact files from Microsoft. A Back -up con macrium reflect free It is recommended before drastic interventions.

Windows charges correctly, but nothing works

If Windows starts, but the peripherals (WiFi, audio, keyboard) do not answer, the problem in the Director Or in incorrect configurations. In Settings> System> Dissolve problemsWindows can automatically correct common errors, such as internet connections or missing audio. For outdated drivers, Spicy driver -installation program Download updated versions without invasive advertisements, unlike a lot of commercial software.

Another frequent cause is the malware. Even in the event that there are missing files or refusal permits, the cause can always be a virus.

Unless sensational cases, it is always possible to remove a virus or malware, only, using Restoration CD if the computer becomes unusable.

The computer works, but is often switched off or is restarted regularly

This is the most difficult problem to identify because the causes can be different: the hard disk has a damaged sector, the temperature control sensors do not work, the fans are not cool enough, the ram is ruined, windows have a virus etc.
With regard to these topics, I have described various typical situations in the articles:
– Answers on blue screen, sudden closure or restart of the computer
– ways to repair windows and make a recovery disc.

I am again in sudden or closing overheating Or hardware problems. Special Monitoring temperatures: if CPU or GPU are larger than 80 ° C, clean fans and dissipators with compressed air. Dry thermal pasta on the CPU can cause overheating, but its replacement requires experience. A power supply Defect is another common cause: testing with a multimeter or replacing it is a solution for desktops.

Frequent blue screens can arise from RAM defective. The tools Windows Memory Diagnostic (Type “mdsched.exe” in the search bar) Check errors. If the ram is damaged, replacing it is cheap and easy on desktop.

The computer is fine, but errors and some programs do not appear

Random errors or programs that do not start can be of software and always resolve. Can depend on corrupt system files or malware. To perform SFC one DismissAs described above, is a good starting point. If the problems persist, there is a scan with Bleach It can eliminate temporary files that disrupt the programs. For example, a corrupt cache of a browser can prevent loading some web applications.

For specific errors, the Event viewer Detailed error codes shows by Windows (type “eventvwr” in the search bar). Looking for these online codes can reveal specific solutions.

To repair Windows of small errors, there are some automatic Windows Resolution tools.
On the other hand, if the problems are widespread, a Windows reset can be made, which does not cancel data, but only removes the programs. This option is all automatic and is found in Settings> Update and Security> Reset> PC Reset.
Thanks to this tool you can reinstall Windows 10 or Windows 11 at any time without using the installation DVD.

In the portable PCs and those who have a partition or a recovery, it is possible to restore the factory settings that in some cases solve any problem as always that the hard disk is not damaged.

The computer is fine, but it is often very slow

A slow PC can depend on a complete disk, unnecessary processes or outdated drivers. Glary Nuts Companies Optimize the register and deactivate programs for starting up, improving the speed. In the management of activities> Start, non -less applications reduce the tax. A slow hard disk benefits from the replacement by a SSDAn investment that transforms the performance.

An observation: a lot of commercial software promises wonderful optimisations, but often slow down the system with unnecessary advertisements or processes. Open source tools such as BleachBit or Snappy Driver Installer are more reliable and transparent.

We have written various guides about this problem, as the one who explains Because the computer becomes slower and slower over time.

I hope that this summary guide about all the things you need to do to repair a Windows computer can come in handy, to find out when you can do it yourself and to be prepared when you bring your PC by a technician, so that you do not seem to be unintentional. When you bring a computer to help, if the user has no idea of the cause of the problem, the technician needs much more time to investigate.
Please note that when you bring the PC to help, you should not necessarily leave for repairs, you can even ask for advice (also paid) so that you know what is wrong and how you can put it at your place (then go home and read Navigaweb).
Although the problems with regard to the configuration of the operating system can always be solved by looking for solutions on Google or starting this manual, when there is a piece of the internal hardware, things can be complicated if it is a laptop. If a desktop pc is in fact always easy to repair, even if you have to replace an internal piece, the speech for laptops is different, where the replacement of a hardware cultivation such as the disk or food can be much more complicated.
