Introducing the main components of PC and laptop
Understanding the main components of a computer and laptop is one of the most important topics in laptop repair, which we want to address in the following topics related to laptop repair training. Knowing the main components of your laptop and computer will help you to be familiar with any problems in your laptop and take steps to repair it more quickly.
1- Motherboard One of the main components of computers and laptops
Motherboards in laptops and personal computers are definitely one of the main and most important parts of it that perhaps a wide range of users have heard the name even for once. But for more information, we need to introduce this very important part in laptops to learn more about it. The motherboard is a fiberboard on which all the electronics components are mounted. In fact, the motherboard is used by BUS highways as a vital bridge for data transfer between components. Now that you are somewhat familiar with the motherboard, look for other sections to learn about other circuits.
2 - CPU is another major component of computers and laptops
Processor, which stands for Central English Processor Unit, means central processing unit. This unit is the thinking brain and of course the most important chip on the motherboard or any computer. CPU has very important functions as one of the main circuits of laptops and personal computers, including managing and organizing the data processing process, providing logical and desirable functions in laptops, direct monitoring and other Directly referred to other parts on the main board as well as other parts of the laptop computer….
A chipset, also known as a chip set, is a set of electronic components in an integrated circuit. The task of this section is actually to manage the data flow between the processors, memory and peripherals (I / O).
It can be said that these parts of laptops are designed and installed in such a way that they have the ability to work with a subset and a set of microprocessors. Therefore, it can be said that due to the fact that chipsets are responsible for controlling the communication between processors, they play a vital and very important role in determining the performance of the system.
4- Hard disk
This piece is a non-volatile information storage device that stores information and provides it when needed. Hard disks in computers are larger than hard disks in laptops and can hold 120 GB to several terabytes. The storage capacity of data on laptop hard drives is less than a computer.
5- Computer memory
Another important component in computers and laptops is memory. Memory in laptops and computers is divided into different types. Random access memory (RAM), read-only ROM, cache, etc. are examples of these memories.
Random access memory (RAM) is used to store frequently used information and instructions.
Read-only memory (ROM) contains important information that is already stored on the system and is very difficult to erase and change.
Cache is another memory on a computer and laptop that holds the next few commands that the processor must process to access the computer more quickly.
It is another component of computer and laptop. Various signs and symbols are recorded on the keyboard, and by pressing each of them, certain signs are imprinted on the computer. There are different types of keyboards: arithmetic, laptop, wireless, multimedia, gaming, multi-purpose, and some types of keyboards.
The mouse is another component of a computer and laptop that has a motion detection sensor that converts motion into digital signals and sends it to a computer and laptop. Mice are divided into three categories: mechanical, mechanical, and optical. Mechanical mice are no longer used today and optical mice are one of the most widely used mice.
These mice detect optical motion sensors and send them to a computer.
PCs and laptops have many components, each of which plays a crucial role in the performance of laptops. In this section, the most important of these circuits and the main ones were discussed in order to become more familiar with this category of common circuits in personal computers and laptops.

4- Remove the CMOS battery
To fix the No Bootable Device problem on the laptop, you can remove the CMOS battery and clear the BIOS memory via Clear CMOS and reset it to factory settings. If you are not familiar with how to clear the BIOS memory, we have taught you how to clear the BIOS memory in a practical and step-by-step tutorial in the Clear CMOS tutorial article.
Other solutions to this problem may also work. For example, you can remove the laptop battery and put it back in place to return to its original state with a single turn on and off, or you can repair your laptop in other ways, or even Leave the implementation of this process in the hands of reliable and skilled people by visiting mobile and laptop repair offices.
What is a Blue Screen Error?
Blue screen error is one of the most common problems in laptops or computers that most users of this type of electronic device have encountered this problem. Maybe this problem is more common for those who deal with their laptops and computers on a daily basis, or that this group of people have struggled with this problem more than other sections of society and it really is. Have touched.
In this article, we will examine this problem from a series of laptop repair training articles; Therefore, we recommend that you stay with us until the end of this post.
What causes a blue screen error or blue screen of death in Windows?
But what is the cause of this problem and why does a laptop or computer suddenly face this problem after using it for a while? One of the reasons that can occur for such a problem is the inefficiency of the required files of the operating system or one of the hardware components of the system, which due to improper operation of the user in such cases causes this to happen. The problem is in front of the user.
The most important reasons for this error can be the following:
- There is a hardware problem or problem with the hard drive or system
- hardware problems
- The ruin of Rome
- Existence of virus in the system
- Overheating of the system
- There is a problem with the power supply
- There is a problem with the BIOS or changing its settings
Therefore, as much as possible, this problem should be prevented from occurring with proper and appropriate action. Perhaps the first question that has occupied the minds of people is what actions they should take after such a dilemma occurs, and in fact, they are asking such questions in their minds, what should be done now?

But because the system restarts immediately, the error can not be read and easily detected. There is a trick to seeing this error. For this purpose, the automatic restart must be disabled. To accomplish this, the following steps must be taken:
First of all, you have to enter the phrase cpl in the Windows search field so that you can easily click on it after the cpl program appears.
Then you need to select the Advanced tab.
In the Settings section, look for the Startup and Recovery option and click on it.
When a new window opens in this section, you must uncheck the box on the Automatically restart option and then uncheck Write an event to the system log.
By performing all these steps in order, you no longer have to worry about facing the blue screen. Because by implementing these steps, whenever you encounter this problem, you can easily read the error in it and find the cause. The hardest part is finding the cause.
