Read about how to find a component that is overheating.
I will describe the causes of overheating in descending order of their likelihood, and solutions, starting with the processor.
Causes of processor overheating and their elimination:
1. The main reason for processor overheating is that the radiator becomes clogged with dust, air exchange becomes difficult and, as a result, overheating - it is necessary to clean the processor radiator from dust, you can do this with a vacuum cleaner, but very carefully and only when the computer is de-energized.
2. If the radiator shines, but the processor still overheats, then the thermal paste has probably dried out; you need to carefully remove the cooler from the processor, remove the old thermal paste from the cooler and processor, and apply new one. You need to apply very little new thermal paste, and keep in mind that coolers on motherboards with socket 775 are very difficult to remove, their legs break off, and it is difficult or impossible to install such a cooler back. Also, when installing a cooler, there is a risk that it will install crookedly (this is not visually noticeable) and the processor will overheat.
3. If after completing the first two steps the processor still overheats, then a slight reduction in the processor supply voltage in Bios will probably help; you will have to select it experimentally.
Causes of video card overheating and their elimination:
And using rubber bands for money, I attach it to the video card, pay attention to the arrows indicating the direction of air flow, they should be directed towards the radiator of the video card. This results in quiet and reliable cooling of the video card, which has already been tested on more than one computer. It should look like the picture:
This method has a slight drawback: after about six months to a year, the rubber bands begin to dry out and fall apart, so you need to change them occasionally, or replace them with something more reliable, for example, a piece of wire from an untwisted twisted pair.
Causes of overheating motherboard and their elimination:
1. As a rule, the south or north bridge on the motherboard overheats, this happens rarely, it can be solved by installing additional fans, usually a place is reserved for them on the rear wall system unit, they must be installed for blowing.
Causes of overheating hard drive:
1. Lack of cooling. It is advisable to install the hard drive in places where there is air movement and preferably in the lower part of the system unit; if this is difficult, then you need to install a special fan for hard drives.
2. High load on HDD, if you constantly use a hard drive, then take care of its additional cooling, in fact, the durability and reliability of hard drives greatly depends on their temperature during operation, hard disks Those that regularly heat up above 50 degrees are unlikely to become long-lived; it is optimal that the maximum temperature of your hard drive during operation does not exceed 45 degrees; ideally, the temperature of the hard drive is in the range of 35-40 degrees.
In most cases, overheating of computers and laptops is manifested by the following symptoms:
The most important components are the processor, hard drive, video card, power supply, motherboard
Signs of a problem: programs freezing, unexpected reboots or computer shutdowns, blue screen. The consequences of this condition are degradation of the chip; the processor may work, but with errors. If the processor has undergone degradation, it cannot be repaired, only thrown away.
The computer freezes while watching a video; after a few minutes of playing, the computer restarts, a blue screen appears, graphic artifacts appear on the screen, the image disappears during operation, and a notification may appear.
As a result of this condition, the video card components are at risk of degradation.
If the hard drive overheats, the computer suddenly freezes, clicking sounds are heard from the system unit, and the system does not boot. Typically, these signs appear when overheating has caused irreparable damage. If you wish to recover data that was recorded on your hard drive, this can only be done through service center. The hard drive itself cannot be repaired, but the information can be copied to another medium.
Dangerous symptoms appear: a burning smell is felt during operation, it turns off immediately after startup, an unexpected reboot occurs, games or videos freeze. The consequence may be failure of the components of the power supply, but repairs to a service center will cost you little.
If the chipset on the motherboard overheats, it manifests itself as follows: the keyboard and mouse turn off, USB refuses to work, there is no connection to the drives and hard drive, the computer freezes, unexpected reboots occur. As a result, the chipset may degrade. If you do not monitor the temperature of the motherboard, you will subsequently have to buy a new one, since repairs are very expensive.
In addition to the above, various batteries on the motherboard heat up. For effective cooling, radiators must be installed on them. But some manufacturers, in order to save money, do not do this, expecting that the motherboard will work exclusively in normal mode. Therefore, at least one fan must be running to cool the components through natural air movement.
Most often, overheating of a computer is manifested by its braking during operation. Usually this symptom is not visible immediately, but some time after turning on the computer. At very high temperatures, the processor does not work efficiently as it tries to lower the temperature. This process is called throttling. Depending on the model, the permissible processor temperature ranges from 65 to 80 degrees.
Throttling also works on modern processors, and on video cards. So if games freeze or slow down, it’s most likely overheating.
Windows is a complex system. If one day the processor produces an error during calculations, then everything is disrupted. As a result, a BSOD failure will occur, or, more understandably, a “Blue Screen of Death.”
BSOD is a serious error that cannot be ignored. By default, the system is configured in such a way that when a BSOD is detected, the PC itself reboots. Thus, if overheating occurs, a blue screen appears and the computer restarts. However, it may just be a “blue screen of death”. The reboot process after the BSOD appears is disabled as follows: through the Control Panel, go to the System, then to Advanced system settings. In them, open Boot and Recovery - Settings, from the item Perform automatic reboot, you need to uncheck the box and confirm your decision.
In fact, there are many reasons for BSOD - malfunctioning drivers and programs, errors on the hard drive. 1.9. Over time, your computer gets hotter - why?
One of the reasons is depreciation of cooling components and dust. To clean radiators and other computer components, it is advisable to use fans that suck up settling dust. Overheating occurs also due to large accumulations of dust.
Over time, fans wear out and as a result they may constantly make noise, spin at a lower speed, or stop altogether. The thermal conductivity of the thermal interface deteriorates. Thermal pastes and thermal pads, which ensure high-quality heat transfer from the processor to the heatsink, require cleaning and replacement.
There are many sensors inside the computer. They measure component temperature, voltage, and fan speed. Their exact number varies depending on the components and their connection options. For example, a cooler with a rotation speed meter can be connected to both the motherboard and the power supply unit (PSU). Otherwise, the speed cannot be measured.
The most convenient utility for determining the temperature of computer components is Open Hardware Monitor. It is capable of identifying many sensors and can show the temperature of the computer hardware, voltage and frequencies.
You can download the program for free from its home page.
The sensors that the computer is equipped with are not calibrated. Accordingly, the error between temperatures can be several degrees. For example, a video card heats up to sixty degrees, but the maximum for it is seventy. Games start to slow down only after a while. Consequently, the sensor does not display the actual temperature, and there is overheating.
Temperature sensors can be located in different ways. Their location is related to the processor model. For example, processor Intel Core The i7-2600K has four physical cores, so there are five temperature meters: one for each core and motherboard.
To find out the processor temperature, look at the CPU Core item, if available. To detect overheating, you should load the processor with a serious task and check the temperature under the load. New games are ideal for this. Play for half an hour and then look at the Max column in the program. To determine the maximum temperature of your processor, look for information in Yandex or another search engine. If you don't know what processor you have, the program shows the model next to the processor icon.
The temperature of the video card elements can be different, depending on the load. Measuring the maximum temperature will help determine overheating. Therefore, the video card must be loaded. An easy way is to launch the game and the Open Hardware Monitor program at the same time. In the Max column you can see the maximum temperature.
Typically, a video card temperature of up to sixty degrees is considered normal. In some cases, it can reach ninety degrees, but specific indicators need to be clarified. The reason for overheating of the video card may be braking and unexpected reboots of the computer.
Temperature sensors can be found in the section dedicated to the motherboard. All computers have different boards, and the number and names of sensors also differ. But none should exceed fifty degrees.
And in some cases this is a lot. In the motherboard manual you can find information about the maximum permissible temperature for the chipset.
The power supply may only have sensors to check the fan speed so that it does not make noise without load. Therefore, it is impossible to measure the temperature of the power supply programmatically. You should touch the body of the system unit with your hands. If it is hot or smells of burning or burning plastic, it is overheating.
If it overheats, you need to change the thermal paste and clean the computer from dust. This needs to be done correctly. If you do not have relevant experience, it is recommended to use the services of a service center. Under warranty, the laptop will be cleaned of dust at an authorized center for free. If there is no service center, you can return it back to the store with a complaint about overheating. In this case, they will do the cleaning themselves. It is advisable to copy all the data from the laptop, as the service center can do this hard formatting disk. In addition, document the transfer of the laptop for diagnostics.
It's the same with a desktop computer. The problem of overheating should be dealt with by the store where the system unit was sold to you. Whether there is dust or not, overheating must be eliminated to avoid damage. In addition, you can clean the computer yourself, but without the appropriate knowledge and care, there is a high probability of breaking something.
If you have little understanding of the layout of computer parts, you should not disassemble it yourself. If a fault is detected, you will still have to take it to a service center.
If you remove the cooler, you must apply thermal paste between the processor and the radiator. You can buy cheap KPT-8, which is sold in any specialized store. You should not collect and reuse the paste that was there, firstly, over time it loses its ability to effectively conduct heat, and secondly, when removing the cooler, dust falls on the paste. Therefore, you will have to smear a new one. The layer should be thin and not flow beyond the surface of the lid and processor. A lack of paste will not allow for high-quality heat removal.
Instead of thermal paste, developers can use thermal rubber bands. In some cases, they are much more effective, for example, if the distance between two elements is more than a millimeter, the parts cannot press tightly against each other. This is especially common in laptops.
To cool the hard drive, you can place a fan on the front panel of the system unit; there are usually mounts for this. Vacuuming computers and laptops is not advisable. One reason is inefficiency. Also, due to the strong air flow, dust gets into hard-to-reach places and it will be impossible to get it out.
A cooler is a symbiosis of a radiator and a fan. This device removes heat more efficiently. Its location is video cards, processors, motherboard chipset. Conventional fans (without a radiator) are located in the case and power supply. Since certain components for cooling are simply enough air flow.
Cooling can also be passive - only the radiator works, the heat from which is lost due to the movement of air inside the system unit. This is often used on low-power video cards. Modern motherboards also only have passive cooling. But it is useless if there is no air movement inside the computer case. Therefore, with passive cooling, at least two fans must be installed in the case - one for exhaust, the other for injection.
Operation of various nodes personal computer(PC) is provided using special control circuits. The current level of development of component miniaturization makes it possible to combine such control circuits in one microcircuitry product, called a chip.
There may be several such chips on the motherboard (MB); they are called bridges, by analogy with the transport function of bridges. Traditionally, the chip that works with high-speed PC components is called the north bridge (NS), and all other components are connected to the south bridge (SB).
In this article we will look at what the north and south bridges are, what role they play in the operation of a PC, where they are located and how to diagnose them.
These devices have their own role in ensuring the operation of certain PC nodes; let’s look at what each of them does.
The answer to the question, what is the north bridge on the motherboard, is essentially the answer to what kind of motherboard we have. The main functions of the motherboard are contained in it. It provides data exchange between the processor and memory, as well as high-speed external devices connected to the PCI and PCI-E buses.
The functions of the north bridge on a laptop motherboard are similar to its function on a PC board, with the only difference being that a laptop video card can also be built into it.
The functions of YUM are to ensure the correct operation of all other devices that are part of the PC or connected to it. These include:
These devices are located close to the locations of the components they support. In the place where the CPU is located, there is also a north bridge, where the periphery is located - the south bridge.
The YuM is located in the lower right part of the motherboard, as close as possible to the SATA, USB connectors and places where other peripherals are connected.
The north bridge on the motherboard is located in its upper part, as close as possible to the processor and its power supply circuit.
Important! About 10 years ago, almost all CM functions were moved to the processor. All modern processors have a built-in memory access controller and system bus driver. The need for a special chipset, placed in a separate microcircuit on the MP, disappeared by itself.
A complete diagnosis of UM is quite complex and requires the use of special equipment, but preliminary diagnostics can be carried out at home.
Let's look at how to check UM using a minimum of available tools. As such a tool, you can use an ordinary Chinese multimeter. The most common cause of failure of the YuM is the burnout of the power circuits, in which the power signal is “shorted” to the common wire.
You can check this by measuring the resistance of the power circuits coming out of the YuM. The best way to do this is to USB connectors. We switch the multimeter to resistance measurement mode and measure the resistance between the 1st and 7th, as well as between the 2nd and 8th legs USB connector. These legs are always signed, so there shouldn't be any problems.
If the YuM is in order, the resistance should be on the order of several hundred Ohms; if it is significantly less (a few Ohms or even 0), then the YuM is out of order.
Any malfunction of the SM is critical for the operation of the PC, so its diagnosis is elementary: if the computer starts up and begins to boot, then the SM works, otherwise it does not. Naturally, the remaining components (processor, memory, video card, etc.) must be guaranteed to be in good working order, so as not to mistake their malfunction for a false malfunction of the SM.
Any semiconductor components heat up when the current flowing through them exceeds the normal value. This may be due to an increase in the number of connected devices, the use of both software and hardware overclocking, poor case ventilation conditions, etc.
We should talk separately about emergency situations. For example, excessive load due to incorrect connection external devices(too much power consumption on SATA or USB ports, short circuits in these ports, connection errors, etc.). When
In the event of such a situation, time is counted in minutes, and often in seconds. Therefore, it is better to simply not allow them.
This situation arises quite often, since it is the YuM that is responsible for the operation of the entire periphery; moreover, unlike the northern one, to which only the processor, bus and memory are connected, everything else is connected to the southern one.
The best way to reduce the temperature of the UM is to reduce the load on it by disconnecting additional devices, for example, from the USB bus. However, if the PC’s tasks include working with a large number of peripherals, this naturally cannot be done.
Therefore, you will have to look for another solution. The simplest thing is to replace the radiator located on the YuM (and sometimes, not replace it, but install it, since the low heat generation on the YuM often does not require a radiator at all).
For this purpose, you need to find a radiator of suitable dimensions and install it on the YuM chip using hot-melt adhesive.
Attention! Using thermal paste, as is the case with a processor or video card, is not enough, since there are no clips in the mounting mechanism of the bridge cooling system, and the adhesive properties of the paste are not enough to hold the mass of the radiator.
Very often you have to read on forums and social media. networks: “Help! The north bridge is getting very hot, what should I do?” The answer to this question is very simple: in 90% of cases, nothing needs to be done. For SM, working at elevated temperatures is the norm.
It’s another matter when the temperature rises so much that it triggers the internal protection and shuts down the bridge, and with it the entire PC.
There can only be one solution in this situation: improve the cooling system of the bridge. This can be done in two ways: by modifying the passive cooling system or installing an active one.
Remaking a passive cooling system involves replacing the radiator with a more massive one or one with a larger dispersion area. This difference is noticeable even visually. The old radiator should be separated from the chipset, the remaining connecting compound should be removed, and the new radiator should be glued using hot glue.
If you replace the radiator with a cooler (radiator-fan combination), you can significantly reduce the temperature of the microcircuit. For this purpose, you can use any cooler with a fan diameter from 30 to 60 mm.

Overheating is one of the main reasons why laptops and desktops slow down.
The most typical symptoms of overheating computers and laptops:
The hottest components are the processor, video card, hard drive, power supply and chipset on the motherboard. Let's consider each case separately:
Symptoms: Program freezes, unexpected reboots, unexpected computer shutdown, and the appearance of a “blue screen of death.”
Consequences: CPU overheating threatens degradation(destruction) of the chip (processor). In this case, the processor may work, but unstablely, with errors, which will cause constant problems. A processor that has undergone degradation cannot be repaired - it will have to be thrown away.
Symptoms: freezing while playing games and watching videos, rebooting the computer after several minutes of playing, the appearance of a “blue screen of death”, graphic artifacts on the screen (disappearance of textures, the appearance of stripes and dots), disappearance of the image on the monitor both during operation and immediately after turning on computer, the message “The video driver has stopped responding and has been restored” appears.
Consequences: As with the processor, prolonged overheating can cause video card components to degrade.
Symptoms: unexpected computer freeze, clicking sound from the system unit, Windows will not load, read/write errors.
Consequences: Usually, symptoms of an overheated hard drive appear only when overheating has done its dirty work. In this case, if you want to recover data from your hard drive, there is only one way - to the service center. The hard drives themselves cannot be repaired, but there is a chance to “pull” data out of it.
Symptoms: burning smell while the computer is running, does not turn on or turns off immediately after turning on, unexpected reboots and shutdowns, freezing while playing games or watching videos.
Consequences: overheating threatens the failure of the power supply components; repairs at a service center are not expensive.
Symptoms: unexpected disconnection of the keyboard, mouse, USB failure, lost connection to the hard drive, disk drives, computer freezes, spontaneous shutdowns, reboots.
Consequences: like a processor, a chipset (what it is, see Wikipedia) can also degrade. If you don’t keep track of the temperature of the motherboard, you will have to buy a new one, because... repairs are very expensive.
Various batteries scattered around the motherboard also heat up. In the photo above, radiators are installed on and near them for more efficient cooling. Unfortunately, manufacturers often save money and do not install the required cooling, counting on the fact that the motherboard will only operate in “normal” operating mode (without overclocking the processor), relying on air cooling. Therefore, there is always at least one fan in the case must be installed to cool components through air movement.
Of course, the matter is not limited to all these symptoms. I have listed only the most popular ones.
The most common symptom of overheating is “brakes” while the computer is running. Usually they do not appear immediately after turning on the computer, but after several minutes or even hours of operation (when the processor heats up to a critical temperature).
At high temperatures, the processor slows down its performance, due to which its temperature decreases or at least does not increase above the permissible limit. This process is called "throttling". The “permissible temperature” of the processor can be anything - 65 degrees, 70, 80, etc., depending on the model.
Throttling works on both modern processors and video cards. Therefore, if games freeze or slow down a few minutes after launch, it is almost certainly overheating.
Windows is a complex software package. If somewhere the processor produces an incorrect result in calculations (and they will certainly be due to overheating), then everything “collapses”. The consequence of such a failure will be BSOD (from the English Blue Screen of Death - “blue screen of death”).
You can download the program for free from its home page (the size is less than half a megabyte).
The sensors in the computer are not calibrated. This means that the actual temperature may differ by several degrees. Example: the video card heats up to 60 degrees, but the limit for it is 70. However, games begin to slow down after some time. This means that the sensor clearly does not display the real temperature and overheating occurs.
Depending on the processor model, the number and location of temperature sensors may differ.
For example, let's measure the processor temperature Intel Core i7-2600K. This processor has 4 physical cores, so we have 5 temperature sensors: one for each core and the remaining one on the motherboard nearby:
In the screenshot CPU Core- sensors showing the real temperature of the cores, CPU Package- sensor near the processor on the motherboard. Thus, to find out the temperature of the processor, you should look at “CPU Core” (if there is such an item). For the processor from the screenshot above, the maximum permissible temperature is as much as 90 degrees (). However, this temperature is not acceptable for all processors. Sometimes 65 degrees Celsius is the limit after which processor degradation begins.
To detect overheating you need to load the processor with a heavy task and measure the temperature under the load. For example, games will do, preferably newer ones. Play the game for half an hour, then watch the column Max in the program window. To find out the maximum permissible processor temperature, search for information on Google or Yandex specifically for your model: “maximum processor temperature ( processor model)».
For those who don't know what processor is installed in your computer: the model will be written in the Open Hardware Monitor program opposite the green processor icon:
As with the processor, the temperature of the graphics card components can vary depending on the load. Measurement only maximum temperature will help calculate overheating. Therefore, the video card needs to be loaded with something. The simplest way- launch any game and play a little (half an hour is usually enough) with running program Open Hardware Monitor. In a collumn Max The maximum temperature will be recorded:
The screenshot shows that this computer The video card temperature under load did not exceed 53 degrees, which is a very good result. Typically, a video card temperature of up to 60 degrees is considered normal. In certain cases it can even reach 90 degrees, but this moment needs to be clarified, entering in Google request something like “maximum video card temperature ( video card name)».
It may turn out that it is the overheating of the video card that is the cause of the computer’s brakes and unexpected reboots.
Temperature sensors are displayed in the section dedicated to the motherboard. Here is a screenshot, pay attention to the icon:
Everyone's motherboard is different, the names and number of sensors vary. No sensor should exceed 50 degrees Celsius. Although in some cases 50 is already a lot.
The instructions for the motherboard often indicate the maximum permissible temperatures for the chipset. If you do not have instructions, download them from the official website of the motherboard manufacturer.
If there are sensors in the power supply, they are only for automatic control of the fan rotation speed so that it does not make noise without load. Therefore, programmatically measure the temperature of the power supply it is forbidden. You need to touch the body of the system unit with your hands in the area of the power supply - usually from the top back or bottom back. The power supply is connected to a cable from the outlet, so you can’t go wrong with the location. If the case is hot to the touch in this place or there is a smell of burning plastic coming out from there, this is overheating.
There is only one answer: Clean the dust and change the thermal paste!
This matter must be approached wisely. If you do not have experience in this matter, consider contacting a service center:
Laptop with valid warranty: An authorized service center will clean it from dust free of charge (under warranty). If there are no authorized (branded) service centers, you can take it to the store where you purchased it with a complaint about overheating. In this case, the store itself will take care of it, sending it to its service center for diagnostics and (if dust is detected) cleaning. It is advisable to copy all important data from the laptop, because the service center can format the hard drive (of course, this is a “severe” case, but it happens). Also, be sure to document the transfer of the laptop for diagnostics - you cannot return the product to the store without clear documented reasons.
Laptop with expired warranty: Once the warranty has expired, it means your laptop is already more than a year old. Over such a period of time there will be a lot of dust in it. You can take it to any service center for cleaning. The service is relatively inexpensive - the most greedy service center charges no more than a thousand rubles for cleaning a laptop from dust.
With desktop computer under warranty the situation is similar. The store where they sold you the system unit must deal with overheating issues. Whether there is dust in the system unit or not, overheating must be eliminated to avoid damage.
Desktop without warranty(or expired) can also be cleaned for you at the service center. Of course, for money.
You can clean your desktop computer yourself - here are good instructions. However, remember - without proper knowledge and care, there is a high risk of breaking something. There are also good instructions for cleaning laptops from dust. The design of laptops varies from model to model, so most likely you will also have to look for disassembly instructions for your specific laptop model.
These tips are “cries from the soul.” A situation often occurs when a novice user starts cleaning a computer without understanding some of the subtleties. So I advise you to read and gain knowledge:
Cooler- this is a radiator plus a fan. This technical solution removes heat much more efficiently than if only the processor was blown fan. Coolers are usually installed on processors, video cards, and motherboard chipsets.
Fans(without a radiator) are placed in the case and power supplies. Some components simply require air movement to cool, i.e. banal airflow.
Cooling of components can also be passive- only a radiator is installed, the heat from which is lost due to the movement of air inside the system unit. This is a common solution on low-power video cards. Modern motherboards also have only passive cooling on their components.
An important point: passive cooling is useless if there is no air movement inside the computer case. Therefore, with passive cooling, at least a pair of fans - one for injection, the other for exhaust - must be installed in the case.
Of course, the pictures above do not show all possible models of cooling equipment. Human imagination is inexhaustible. There are also cooling using water, oil, liquid nitrogen, etc. All this is covered in the guide to cooling systems, the link to which I have already given above. If there are any points in the article that you do not understand, write in the comments, I will try to answer and supplement the text.
All more or less literate PC and laptop users have probably heard of such concepts as the south bridge. However, it is one thing to hear, and quite another to understand what it is and why it is needed. When these components fail, repairmen limit themselves to a faceless phrase like “the north/south bridge has burned out, replacement is required.” And no one will bother to explain to the poor user what exactly happened to his computer. And knowing this is very useful. Therefore, let's look at this topic in this article.
The motherboard's south bridge is a controller that is responsible for the operation of some important computer components. It controls the operation of USB ports, PCI slots, power, direct memory access controller, interrupt controller, real-time clock, sound controller and other important components. Without this component, normal computer operation is impossible. It simply won't turn on if the bridge suddenly fails. Therefore, you need to monitor it carefully.
Of course, if the south bridge of a laptop fails, it is not as fatal as in the case of the north bridge, but it is still unpleasant. After all, then the PC or laptop simply will not start. But there are no problems with diagnostics. It is immediately clear that it burned down. But let's move on to this very diagnosis and figure out how to understand that this particular bridge has failed.
As a rule, diagnosing a malfunction is the first step to understanding the problem and understanding further actions. How do you understand that the south bridge is "dead"? Very simple. In most cases, the computer simply does not turn on and beeps obnoxiously. But here it all depends on the degree of damage to the controller. In the case of laptops, USB ports, touchpads and other peripherals, which are entirely dependent on this bridge, may not work.
Also, a symptom of a malfunction of this particular element may be an incorrect global time in the BIOS and operating system. The option of complete disappearance of sound is also possible. Even the fact that the southbridge heats up higher permissible temperature, can be a very alarming symptom. This can only mean one thing: it will burn out very soon. Therefore, urgent measures need to be taken.
There can be many of them, but the most common is overheating. Southbridge is essentially a chipset. Therefore, it needs high-quality cooling. If the cooling system of a PC or laptop malfunctions, there is a very high probability that the controller will burn out. Physical damage is also very popular. All it takes is a small blow in the right place and the fragile structure of the chipset will be irrevocably damaged. And this is a direct path to the service center. There is no way without this.
There is also a very high probability of liquid getting on the motherboard in the area where the south bridge is located. One drop is enough for it to happen short circuit. The controller will burn out very quickly. Another common cause of failure is a defective chipset. But this is very easy to check, since manufacturers post a list of defective controllers. They will break anyway. And it doesn't matter whether it's a south bridge or a north bridge.
The trouble is that repairing such a component is impossible. Only replacing the south bridge will help. The fact is that a person cannot repair the chipset, because it was created by high-tech robots. The person lacks precision. And no one has such tools. So you still can’t do without a visit to the service center and repairmen. Just don’t give your computer into the hands of any “craftsmen” who promise to change the bridge for half the price. Such a would-be specialist can easily kill not only all the bridges, but also other very fragile computer components. Contact only professionals.
If you have a obviously defective controller installed in your motherboard in place of the south bridge, and the manufacturer confirms this, then you can replace it immediately after purchase. It won't cost you a penny, since this is a warranty case. They will simply install a chipset without any defects. It is better not to delay and immediately contact an authorized service center, because the consequences can be very sad if this matter is put off for a long time.
In order for the south bridge of the motherboard to work for a long time and without any problems, you need to observe very simple rules operating a computer or laptop. Firstly, do not neglect cleaning the device from dirt and dust. Even a small layer of dust can damage the bridge controller. And coolers and ventilation slots clogged with dirt can easily lead to overheating and failure of the element. Secondly, you should not expose the device to physical impact. The slightest damage can have the most dire consequences. You should not neglect this, because you can lose not only the south bridge of the device.
Thirdly, do not have the habit of eating or drinking near your laptop. Spilled tea and coffee can cause fatal consequences. One drop of any liquid is enough for a short circuit to occur and the south bridge to fail. Also, don't take your laptop into the bathroom. Even if you don’t paw it with wet hands, condensation has not been canceled. Fourth, keep pets away from your laptop or PC. Wool very quickly clogs ventilation slots, coolers and other components of the cooling system. Hence the overheating and failure of the south bridge. Use your device carefully. And then you won't have problems.
So, above we discussed such a component of a computer or laptop motherboard as the south bridge. Now you know what he is responsible for. Although this controller is not as important as the north bridge, you won’t be able to turn on a PC or laptop without it. To ensure that this component is safe and sound, it is enough to follow simple rules for the safe operation of your computer. Then your laptop will serve you faithfully for quite a long time. Now you know how to diagnose the failure of this particular system component. And never turn to “traditional craftsmen”. It is better to entrust the gadget to professionals.
