In general, when a computer malfunctions or suffers from inconvenience, there are a number of software problems (such as cases that can be solved by resetting and pushing the format) in recent years. It is often not available.
If it is a symptom that can be caused by a component failure, it is a bootable industry term that cannot be booted universally, and an industry term that does not display a screen, screen fire, and desktop booting are good. There are not many symptoms.
Also, there is a phenomenon that the power does not turn on. In industrial terminology, it is said that it is not powered or unpowered. In this case, there is no power LED light or fan turning at all. is.
Your PC was not powered on. That's why we asked a computer technician for a computer repair in Baegok-dong, Siheung-si.
In case of a power failure problem, the theoretical cause is that the power supply (power supply) is broken, or the main board power supply is defective (just the main board is broken), or in rare cases, the power switch in the case, that is, the A contact It can be summarized in three cases where the power is not turned on despite the fact that most of the core parts are defective.
So I will systematically check those parts and finally check the power problem, and replace it with the rated power to solve the power problem.
If you open the lid, you can see inside the PC.
There was some dust on the CPU cooler side, so I couldn't shake it off immediately.
It was a situation where maintenance was being carried out at 11 o'clock at night, and it seemed to be a nuisance to the neighbors who played the compressor, but eventually confessed the next morning.
Dust is not that big of a problem, but it should be repaired fine to the customers, and it should be shown that there is no internal dust, but it is good to color (?) And does not fall off.
It is a convenient tool for checking and managing power failure problems that are not turned on.
It is called a power supply tester, that is, a power tester, and that helps to easily fix the cause of the power failure problem.
Of course, even if you don't have that device, you can check it by connecting it to the used power that works normally for testing purposes. .
I tried to plug the main board 24pin main pin into the tester.
When the power is applied in a low state, the power tester operates, and the fan in the power is turned on even at the power supply, and the operation feeling that power is turned on is just right. This may also be seen in the video at the bottom of the current post, but your PC did not work with the tester under low conditions.
In other words, if it is a power problem, connecting the tester to low power does not work, and if the tester works, it is very likely that it is a main board problem.
For this reason, it is true that the inspection through the power tester is helpful in terms of maintenance convenience.
Connect the test power. However, I checked that the power turned on well and the screen appeared on the monitor.
In this state, if it is confirmed that the power switch operates at once, it is not a problem with the A contact of the case.
If the power does not turn on even after doing so, contact the mainboard power switch with a screwdriver to check whether it is turned on by temporarily replacing the role of A contact.
So here it is that the inspection is over, that is, only the power needs to be replaced. Detailed selection and confirmation of the situation after booting is a basic matter after replacing the power.
It's a very obvious story, but if the A contact is defective, if only the A contact can be physically repaired without compromising the appearance of the case, that's the way to do it.
This is the state of turning the wiring on the right side and side before removing power.
Wiring like that doesn't seem like a good thing.
Of course, unless it's a special incident (burning combustion).
However, if you do that, if the covering of the wiring is peeled off in the visible part of the back panel of the main board, if it is a thin matter, it may be blown out by the stripped place. I will arrange this part in my own way while also replacing the power.
Remove the graphic device (VGA card).
If you don't remove the graphic device, it can be a little annoying when you arrange the wiring.
A few decades ago, there was a case where the auxiliary power was not needed for the graphic device, and the volume was smaller than that of the recent years, so it could be possible to take action without revealing it. is.
The inside of the main body is clean when the power that is out of order is removed.
It is rated power, but it is a failed power.
Rated power package prepared by online mall. It's unexpected to come in bulk, but it doesn't matter because it's not even one that impairs quality and quality.
Corrected the wiring condition before replacing the power.
Actually, I am not good at wiring. Still, since the color is a computer repair contractor, it's not the basics, so I try as much as possible and consider what is safe and comfortable.
Still, the limits of dexterity (?) Are inevitable, but anyway, as much as possible, avoid wiring between the back of the PCB board and the cables as much as possible, and to some extent roll the brain and arrange the wiring. At least, there should be no fire days.
If any of you read this, if you are in a state of concern, disadvantages, or a better way, I would like to comment.
This is a 600W rated power Skydity Power Station 5 product that has been unpacked. It is also my favorite product these days. There are cheaper products, and there are more expensive luxury goods, but that product seemed to be the most reasonable option. Perhaps if you are a productive person or know a little bit about the maintenance, I would believe that if you choose that product, you will still be able to understand the sincerity that it is for you.
After installing a new power product, the final wiring is in a state of being cleaned.
It is very neat and beautiful, but it will be difficult, but I am satisfied with this.
In fact, the rated powers are much more than those of ordinary powers, so it can be said that it is very overpowering to show beautiful and handsome condition even if any of our colleagues do wiring.
First of all, it is important to try to exert at least the basics. And while working, I always think and think inside. What's a better way to do something like how to tie the line to the situation and to hear which one is better?
The inside with the lid on the left side where the core parts are visible is cleaner.
Wiring that may look a little coarse considering the neatness of the front part and the safety of the back part,
It can be compared to "light and shadow".
In the case of the past, I didn't actually turn it to the back of the case, but nowadays it seems to be popular.
If I had only seen it here without revealing it to the back, "Isn't it neat? I care a lot." I would like to.
Power is on.
Anyway, it is a decent result, but it means that the inspection was done correctly, and the power change was good.
Above all, we should first thank the online mall representative who delivered us the sky digital 600W rated power, which is not very early.
In the video below, I was able to check the parts that worked well until booting, close the lid, and deliver it to the customer.
As a side note, if you eat a little bit more bad heart,
If you have a conscience, the quacked article will say, "Power and the main board are gone."
Life-style miscellaneous criminals without incidents of conscience will say, "We've all gone to the power motherboard CPU SSD."
Then, we will guide you to the key parts quotation + data recovery quotation.
Of course, this is a cosy example. It is also true that the power and the motherboard are not going out at the same time. Of course it is not unusual.
First of all, he was a very good and kind, sincere office worker who leaves home in the evening without expressing any doubts or doubts. First of all, it's a bit embarrassing that it couldn't be solved immediately on the spot.
If there is a future plan that is more than a sincere comsurier who has to live with the right meaning for bigger things, how can he do life-style miscellaneous things? ......
In any case, the repair of the assembled PC is poor, but above all, I would like to express my gratitude to the customer who left us without any doubt, and to the online mall representative who did not suffer the initial defect.
The prognosis after delivery was obvious. He smiled and replied, and there was no comment or contact afterwards, so news is good news.
You will be reborn as a computer repair engineer who is always trying his best.
At the site where we meet our customers, we will present a service alternative based on cost-performance based on Fact based on sincerity, and we will converge the best results with your choice first.
And in my spare time, I write like this, and I try to review the things that have passed.
Thanks for reading.
