Many of us have experienced computer problems. And it’s good if these are problems that can be solved independently. Worse, if in the end you have to carry the car to a service center. And even if everything is fixed there, it is not a fact that the system will not fail again and will not fail at the most inopportune moment.
If we discard all talk about complex system errors or some kind of mechanical problems, the rest is generally resolvable. On the Internet, a huge number of videos on the repair of gadgets and computer components. So you can see how to change the screen on a smartphone, how to clean and lubricate the cooler, how to replace thermal grease. And what if the motherboard does not start?
Mistakes
First you need to understand what could be the cause of the problem. In general, the motherboard is a complex device on which a huge number of elements are placed: from large components to small bolts, sensors and indicators. Due to the fact that the board contains controllers, connectors, slots, chipset, stabilizers, capacitors, etc., it is difficult to avoid errors.
By the way, the presence of all these elements can complicate the repair, affect the methods of troubleshooting. As a result, it becomes clear that the errors in this case can be divided into mechanical and system. The first ones can be fixed with a soldering iron even at home, although this is a rare case. If the outcome is unsuccessful, physical damage can only be repaired by buying a new device. Sometimes capacitors, power sensors, or similar elements that carry voltages can simply burn out due to the load on the system.
System errors are more flexible. They are easier to fix on their own, although sometimes you have to resort to the help of specialists. But in general, a system error is not a sentence to the device, and if for this reason your motherboard does not start, do not despair.
Who's guilty?
Interestingly, in general, if any breakdowns occurred, either users or poor-quality food are to blame. In the first case, the buyer could inadvertently handle the installation of the board, inaccurately unpack it or use it incorrectly. In the second case, it can harm the power supply, which not only overloads the board, but also “burns” all other components on it.
Also to blame those who sent you the product by mail and during transportation damaged something. There are also unscrupulous manufacturers who sometimes make poor-quality assembly, and also use poor-quality materials, outdated capacitors, weak radiators, forget about the cooling of the chip, etc.
Home solution to the problem
So, if you have any kind of malfunction, and you are more or less versed in the technologies of the PC system, then you can try to fix everything yourself. Please note that interference with the physical condition of the motherboard removes it from the warranty period, and all that will happen is all at your own peril and risk.
It should be understood that the printed circuit board consists of several layers, and this despite the fact that the thickness of the plate itself is only a couple of millimeters. Each layer has got copper conductors, and if there is a problem with them, then most likely, a service center or the acquisition of a new platform will help you.
Previously, in older models, condenser bloating often occurred . This problem could easily be fixed with a soldering iron. If you have already used this tool, understand how it works, then you can try to solder small parts, while monitoring the temperature, as well as using a thin sting.
Device
Before you rush to fix the breakdowns or figure out why the motherboard does not start, you need to diagnose the "ailment". Usually in service centers use the so-called multimeter or multitester. The tool got such a name due to its multifunctionality: it can check several indicators.
There are a lot of these devices. They need to be able to use, understand what the difference between the analog and digital tester is, which will allow you to check the stability of the platform. A digital device is the most comfortable to use, it is easy to work with, and it does not require special skills, especially if you have a high-quality model on hand.
As a result, the multitester can indicate voltage, resistance, measure current strength, check resistors, transistors, diodes, battery capacity and capacitors.
Replacement
Of course, almost none of the ordinary users at home have an extra multi-tester in their box. Therefore, it is necessary to diagnose the breakdown by all possible methods. If your motherboard turns on but does not start, you will have to change it.
The main advantage of a PC is that there are many components that can be replaced in the case. To find a faulty module, you will have to turn off each component in turn. It is worth remembering that a lot depends on the cables, cables, contacts, connectors and other things. This all often leads to a breakdown of the fittings.
Usually, checking the operation in this way and isolating the faulty component, experts recommend leaving the motherboard with a chip, a power supply and a speaker in order to monitor the sound signals. If this all works, then most likely the matter is in one of the disabled components. Next, it is worth connecting each device one at a time and monitoring its performance. Some do the opposite, taking out each device in turn.
If during this diagnosis you find that the board starts up, but, for example, the video card does not respond, this does not mean that the graphics accelerator failed. There are problems with cables, with connections and contacts on the same system board. Therefore, you will have to check everything, connect the video card to another PC, replace the cable, etc.
Cunning
The reasons why the motherboard does not start, the fans are working, or the platform does not show signs of life at all, are completely different. Interestingly, even the system itself can simply "trick". For example, if the BIOS battery has run out on the board, or it is simply missing, the system “pretends to be dead”. For this case, a multi-tester is just perfect, and if you do not have it, bring the product for repair.
There is also a problem with the supply of standby voltage. To understand whether everything is working properly on this side, you need to connect the power supply to the board and insert a power cable into it. If your platform model is not very old, the LED on it will light up. If the light does not come on, most likely you will have to go to the repair again.
Common problem
It happens that the motherboard does not start, but the fans spin. The problem is not the most common and is often seen on older models of the motherboard. Owners of such devices need to know that problems of this type are often caused by carelessness of the user. In this case, regular cleaning will help. In fact, such a prophylaxis should be carried out at least once every six months: check the condition of the system, clean the motherboard of dust, monitor cooling and thermal grease. If you abandoned the board, then you should not be surprised that a large accumulation of dust led to a violation in the contacts.
In this case, the most successful option is to check the operability of each connector. It is possible that the place where the power supply is connected is very dirty and requires regular cleaning. It also happens that malfunctions in the connectors are noticeable during external inspection, then it is much easier to understand what needs to be done next: just change the cable or change the connector.
Capacitors
It is interesting that if the Asus motherboard does not start, then they try to blame the capacitors. In general, the manufacturer is considered conscientious and always equips its models with high-quality materials. But in older models there are flaws. Some users decide to solder these parts on their own, but they do it poorly, which again entails system errors. It happens that the capacitors change in the service center, and the motherboard ceases to “live” after a while.
No answer
It also happens that the motherboard starts and immediately turns off. Usually people start to think that the computer has overcome a terrible virus. He "ate" everything that was, and there is no turning back. This is a rather rare explanation. Immediately it is worth checking whether the PC power button is stuck, then you need to look at the system unit and clean it from dust.
Yes, again, you will have to turn off everything in turn or turn off all at once and leave the basic elements. It happens that the PC does not turn on because of the power supply, which does not perform its basic functions, although in this case the motherboard would not turn on at all. It also happens that the BIOS will indicate the cause of the problem, which will emit a specific sound signal.
Where is the image?
Some users are faced with the fact that the motherboard starts, but there is no image on the monitor. Of course, the first and main reason is the breakdown of the display. But this happens quite rarely, much more often users simply forget to connect the monitor to a power outlet. It is also necessary to exclude cable damage and activation of the power button on the monitor.
The next reason for this error is BIOS. It sometimes resets the settings and in general can affect the operation of the motherboard. Usually, everything is solved if you get into the BIOS settings. But the monitor is silent, so we open the PC case and look for the battery. It is responsible for the non-volatility of the memory and stores the BIOS settings. We take it out, wait a couple of seconds and insert it back.
As mentioned earlier, there may be problems with other components. Remember that even dust can be your worst enemy, so if something happened to the PC, immediately open the case and view each element. Malfunctions can be visible, for example, you can get the motherboard and examine it for dark spots, charred elements or a pungent smell.
Transistors
If your Asus or other company motherboard does not start, the reason may lie in transistors. This is another element that in general can be independently verified. We are looking for a short circuit to them. Although this happens quite rarely, but, as they say, warned - it means armed.
For diagnostics, we again release the board from all power connectors so that it does not inadvertently become electric shock. We take a multi-tester (yes, unfortunately, those who do not have this device can not make this diagnosis) and check all the outputs of the transistors. This element is difficult to find on the board, since it is small, and there are a lot of parts on the platform. A transistor looks like a square or rectangle with three pins.
Further, the multimeter should work in the “ringing” mode of the diodes. Two elements of the devices need to touch the "legs" of the transistor. A squeak indicates a transistor malfunction.
Details
All of the above reasons are not the only ones. In general, there are a huge number of errors that lead to the fact that the motherboard does not start. The first thing to remember is caring for the system. You can’t buy a PC and forget about it, it is important to take care of it, clean it, monitor the heat, etc.
Among other failures that can disable the motherboard, one can name the incorrect operation of the network adapter - this is the cable that connects the Internet to the system. Unstable routers, Internet centers, and other devices can cause power surges that can burn the circuit.
Often, users encounter problems in the operation of BIOS. Because of them , the Gigabyte motherboard may not start . Typically, manufacturers are trying to introduce a newer model of this multi-program platform. But if an ordinary battery suddenly dies on the board, then no system implementations will help. You just need to replace it.
Nutrition also plays a key role. When assembling a PC yourself, you need to calculate the required power, which the power supply can handle. In addition, one must not forget about good cooling, as manufacturers, saving on materials, forget to install a couple of extra radiators on power elements or use weak stabilizers.
Another reason that your Asrock motherboard does not start is because of damaged ports. Not everyone knows, but turning off the peripherals while the PC is running can adversely affect the elements of the board. For example, if you sharply stick your mouse out of the connector, a power surge will occur that will cause the port to burn. And it’s good if only the connector turns out to be inoperative ... And if the entire motherboard burns out? Have to collect money for a new one.
findings
So, remember: if your motherboard does not start, most likely you will have to take it to repair. This is the most logical option that will make your life easier, although it will require additional funds. If you are more or less versed in the PC, you can try to fix it yourself - because sometimes, as we learned, the problem can be hidden in a dead battery or a disconnected cable.
Therefore, we check that all elements are connected firmly, and the power supply is on. Next, we look to see if all the voltage regulators and processor jumpers are in the right position: it is necessary that all components are firmly “sitting” in their places. If nothing happens, take a closer look at the board and look for visible damage, connect only the necessary elements for the initial operation. If everything works, then the reason lies in one of the disabled components. If the problem persists, then it is better to contact a specialist.
