I contacted the company to repair my laptop, Windows would not boot. They arrived promptly and repaired it within two hours. I’m very pleased, I recommend it to everyone, you won’t regret it.
Ekaterina Maksimova
I suffered for a long time with the problem that the computer was constantly slowing down and finally decided to call a technician. I was very lucky that I turned to the REMIT company. A nice young man came to me and quickly determined what was wrong with my computer. Now everything works fine, the only drawback is that the technician was a little late and was 15 minutes late. That's why I give it 4, but otherwise everything is super.
Andrey Frolov
There was a problem: photographs for 5 years were missing, I was very worried and thought that it would not be possible to restore them. I decided to consult with a specialist on this issue and immediately came across the REMIT company website. There they immediately told me not to worry and offered to place an order for a data recovery service. The master turned out to be highly qualified; he tinkered with the computers for about 4 hours, as a result, all the data was saved. I am very grateful to him, if you have a problem with your PC, contact this company.
Galina Matveeva
The Samsung laptop had a strange problem; it turned off after 10-15 minutes of operation. I decided to call a specialist and determine the cause of the failure. The technician immediately said that the problem was that I had never done any maintenance on the processor cooling system. After a short period of maintenance, everything began to work perfectly. I am very pleased with the quality of the services and their inexpensive cost. I RECOMMEND
Elena Fokina
I didn’t expect the Internet to disappear on my laptop, I called the providers, they said that everything was fine on their line, most likely there was some kind of breakdown in the computer. I called the technician, after carrying out diagnostics, it turned out that I myself had clicked the switch to turn off WI-FI, and this was the reason for the lack of Internet. The technician immediately turned everything back on and said that everything was fine with my laptop. Thank you very much, I recommend it to everyone. The guys know their work very well and the most important thing is the honesty of the specialists. If you have problems with your laptop, I recommend coming here.
Katerina Frolova
Many thanks to the Remaiti team for their prompt assistance! I recommend it to anyone who, like me, often experiences sudden software failures and needs to set everything up in a new way. Upon my first call, the guys quickly arrive and install everything.
Irina Novikova
I recently bought a laptop abroad, I needed to Russify it and install human Windows. I contacted the RemIt company - the master immediately came to my home and quickly set everything up. Thank you very much, wish there were more such good companies!
Ivan Girov
We bought a laptop as a gift for our father and didn’t think to look at what OS it was running on; it turned out that it was long outdated Windows XP. I called Remaiti, the master responded promptly and came to our call. I reinstalled the OS and installed the required minimum programs right in our home! Everything is of high quality and for quite affordable money. Thank you!
Nikolai Alexandrovich
I recommend Remaiti to anyone who needs any technical assistance with computers. I often call these masters to our office. There is a lot of technical equipment and from time to time either the computer or the laptop breaks down. The craftsmen are smart, they repair computer equipment right in the office. Thanks guys!
Irina Alekseeva
I am a student and constantly work with a laptop. Recently it went down, just turned off and I couldn’t resuscitate it in any way. As luck would have it, all this happened before the session and all the coursework was stored on my laptop. I was in a terrible panic until I found Remaiti's company. Thank God, the guys immediately figured out what was going on, reinstalled the system and restored all the data. This is a lifesaver, thank you very much!
Igor Litvinyak
I recently contacted RemIt because of strange PC behavior. It turned out to be a virus. Fortunately, I made it in time. I'm very pleased with the result. The technicians removed the viruses, checked the entire system, configured something and now the computer works much faster. I recommend to all!
Mikhail Myrzin
The Remaiti company has already helped me and my friends out with problems with computers and laptops several times. They fix any breakdowns, even the most abstruse ones, and provide a guarantee for their work. In our time, this was very surprising and pleasing. Thank you!

Thanks to the guys, they quickly responded to the order, came to the house and repaired the PC. They even provided a guarantee for subsequent service.
Yasmin Seviryan
I liked the work of the RemIt specialists; they repaired my PC. I thought that I would have to buy a new one, because all the parts were already outdated, but it turned out that I just needed to buy a couple of new components and optimize the old ones. Everything works great, I didn’t even expect it. Thank you!
Erika Pavlyuk
I recently caught a virus on the Internet (be careful, there are a lot of them now!). I had to look for saviors. I am very pleased with the work of the Remaiti company, the specialists completed everything in the shortest possible time and provided a guarantee. From now on I will always turn to them whenever my PC breaks down. Thank you!
Niikita Mayuk
When my computer broke down, I was already thinking that it could only be thrown into a landfill, but a friend advised Remaiti that maybe they could save it. I called the technicians, took a look, quickly figured out what the problem was and replaced the faulty parts. They always have a large assortment of any hardware in stock. Thank you for resuscitating my friend!
Inna Yatsenko
I don’t know how I would live without my laptop if it hadn’t been repaired! Many thanks to the Remaiti company, which not only fixed the breakdown but also fixed some parts, and the laptop began to work even better than before.
Andrey Antonyuk
My wife and I recently started mastering the computer and needed the help of a specialist. The children are far away, there is no one to help or tell them, so friends recommended the company Remaiti, which understands everything related to computers. They told me everything, installed Windows, checked the system for viruses, advised me what I needed to buy from peripherals (just as advice, they didn’t even charge me for the consultation!). Later we asked for help when some part broke down, they had everything in stock. They installed a new one right there on the spot. We are happy with everything and will recommend you to our friends.
Svetlana Yesin
I am very pleased with the Remaiti company for their qualified and prompt assistance with laptop repair. I had to save my son before the session when his computer burned down. Specialists from Remaiti quickly got up to speed and revived not only the hard drive, but were also able to restore the entire laptop. Thank you very much!
Marina Lavrinova
For a very long time I was looking for someone who could help me repair my laptop, for some reason it overheated and stopped turning on. After much torment, I found the company RemIt, which was able to help me quickly and for little money. Thank you very much guys! Prosperity to you.
Evgenia Ramonov
I advise everyone to contact Remaiti in case of computer breakdowns. I had to turn to them when there was no longer any hope of saving my unfortunate computer. The guys arrived and actively tried to repair it for a good half day. Fortunately, they were able to find all the causes of the problem (they replaced a burnt-out fan and something else, I’m not good at technology).
Stepan Kachur
Remaiti always finds a way out of any difficult situation with computers. A specialist came to us to find the reason for the failure of several computers at the company at once, it turned out that the whole reason was a network malfunction, which confused our entire work. Thank God, we managed to save our computers and establish a workflow, thereby avoiding production downtime. Thank you!

Paul Orlov
For the first time I encountered a problem that the laptop stopped working. I chose RemIt. They fixed it the same day.
Date of publication: 05/18/2015In this article I will talk in detail about how to identify RAM problems. We will also figure out how to repair and replace RAM using the example of a PC, laptop, and the examples of Windows and Linux.
I will try to describe everything in detail and clearly. Therefore, beginners will be able to figure it out, and experienced users will find something interesting for themselves.
Terms:
RAM is the official name for random access memory.
A RAM stick is a chip that represents random access memory.
How can RAM go bad?
RAM is a chip inserted into a special slot in your computer or laptop. Naturally, a computer has more RAM, but a laptop has less. A stick of RAM is the most reliable piece of hardware in your computer or laptop. According to statistics, they break down the least often, and therefore the warranty period for them is longer (on average - 4 years).
This is due to the simplicity of the chip. It practically does not heat up, and therefore does not need a cooler (fan). In rare cases, a radiator is placed on the operating system for cooling, but this usually occurs on powerful gaming computers. In addition, the heatsink makes the RAM bar structurally stronger.
RAM can only be damaged physically. Those. Not a single virus or software problem can yet spoil RAM. Therefore, the most common causes of the problem are:
1) Manufacturing defect.
2) Problems with the power supply.
3) Mechanical damage to the RAM stick or connectors.
4) Static voltage.
5) Simple wear and tear.
6) Overheating/hypercooling.
Manufacturing defect is rare. In 1% of cases, and this does not depend much on the manufacturer. This is due to the fact that all microcircuits are tested by the manufacturer. In addition, the warranty period for RAM is long. Therefore, it’s enough just to go to the service center and change the RAM stick under warranty.
Problems with the power supply are rare. The power supplies and motherboard memory contain controllers that do not allow them to produce a voltage greater than expected. However, there are cases when it is a voltage failure that spoils the RAM. Unfortunately, you can only check this with a voltmeter, which most people don’t have at home (but in vain). If the problem is in the power supply, then you will have to replace it too.
Mechanical damage- the most common case. This usually happens when you try to force insert a stick of RAM. Sometimes it is not the chip itself that is damaged, but the connector.
Static voltage is extremely rare. In my practice, I have never encountered this. The computer system unit and the laptop case are always closed, and therefore static voltage is eliminated. In addition, modern devices have an antistatic mesh under the motherboard. However, static voltage can become dangerous. For example, if you walk on the carpet in rubber slippers, and then reach into the “insides” of the computer with your hands.
Simple wear happens over time. Nothing in this world lasts forever. A RAM stick can deteriorate either after 4 years or after 15 years. It all depends on the operating conditions and the manufacturer.
Overheating or hypothermia It can also ruin your RAM. But this rarely happens, since completely prohibitive temperatures (+100C, -45C) are required to damage the microcircuit. Clean your computer and laptop from dust and everything will be fine.
How to fix damaged RAM
No way. If a stick of RAM is damaged, it is almost impossible to repair it. If the problem is the connector or contact wear, then something else can be done. However, the microcircuit itself cannot be repaired; it can only be replaced. Luckily they are inexpensive. 2GB at 1600Hz costs around 1500 rubles, which is quite a bit, considering the warranty period. Just try not to buy RAM with a warranty of less than two years.
However, don't be scared. Problems can be solved.
What signs indicate a defect in RAM?
General signs:
1) The system does not start. Or it starts to reboot itself endlessly, trying to start normally.
2) The system does not start at all. Usually accompanied by squeaking. This means that the RAM is not detected at all. This means either the RAM stick is very damaged or the connector is damaged.
Windows:
1) The blue screen of death appears. Blue screen with technical information. The error code most often varies. That is, there is no point in googling the error, because... The codes are always different and always show a different reason. Sometimes this happens because the RAM stick is not fully inserted.
2) System malfunctions. This is usually associated with programs and games that actively use RAM. A striking example: programs, browsers and games crash with a system error. Sometimes accompanied by a crash into a blue screen.
Linux:
1) System malfunctions and program crashes. Sometimes it turns out funny. You go to the browser, it crashes with an error, you try to view the bug report, but it also crashes with a system error. Even if you look at the logs, it’s still not always immediately clear what the problem is. Typical for all Debian-derived distributions.
2) The system does not boot. It crashes to the console or writes an error. Although maybe for some who use Arch or LFS, this is how it was intended :)
How to check RAM for defects
The easiest way to check RAM is to download and install on a flash drive or CD (does anyone else use them?!) the special utility Memtest86.
There is Memtest86, and there is also Memtest86+. The difference between them is small, so you can download any one on the official website: www.memtest.org
This archive contains an automatic installer for a USB flash drive. Those. insert the USB flash drive, launch the program and follow the simple instructions. Then you insert this flash drive into your computer or laptop, boot from it and check the RAM.
If you have Linux, then Memtest86 comes bundled with images of Debian, Ubuntu, Fedora and some others. The utility can also be launched from the grub menu at startup. If you don’t know what grub is, then it’s too early for you to start using Linux :)
But! Before you run the program from a flash drive, you need to do the following.
Step 1.
First you need to find the microcircuit. It's easy to do. The RAM looks like a rectangular chip. For a computer it is longer, for a laptop it is shorter.
The microcircuit is clamped on the sides with clamps (a tautology, yes). The clips are easy to open and then pull out the RAM stick. But before you pull out the chip...
Step 2.
Reset your BIOS settings. When the system starts, press Del and the BIOS menu appears. Select the Set to Default option (by default F9 or F10). Then save and reboot.
This step is not required, but the philosophy of fixing hardware requires this step. In some cases, resetting the settings helps the system work.
Step 3.
Pull out the RAM chip and look at its condition. If the contacts are dirty, then take an eraser and gently wipe them lengthwise.
Step 4.
If you have one stick, then put it in the connector and run Memtest from the flash drive. If you have several RAM chips, then leave one and take out the rest.
Step 5.
Once you run Memtest, it will immediately begin checking your RAM. It looks like this:
In the image I have marked the program zones with color.
Green - characteristics of your processor (CPU).
Purple - verification stage and verification percentage.
Yellow - the model and characteristics of your RAM. Remember them or write them down, because if you want to buy a new stick of RAM, you will rely on these characteristics.
If the program detects errors, it will mark them in red. Even one mistake is already a reason to replace the RAM.
Step 6.
After checking, turn off your computer or laptop. Then take out the RAM again and insert it into another slot. Run Memtest again.
If errors appear again, then you need to replace the RAM stick, because... it can't be repaired.
If no errors appear, then the problem is in the connector.
If you have several RAM chips, then check each one in turn. If the problem is in the connector, then simply do not use it, or take it to a service center to have it fixed.
Problem solving
If Memtest gives red errors, then your RAM cannot be cured. Buy a new one.
Of course, if there are not many errors, then you can continue to work with this RAM strip. But as soon as some program stumbles upon a damaged sector, glitches and crashes will begin. If you use Linux and can compile the kernel yourself, then based on Memtest86 data you can build a system that would not use the specified memory areas, avoiding errors.
However, remember! If Memtest86 detected errors in memory, then the wear-out process has already begun. This means that over time, there will be more errors until the RAM completely deteriorates.
Replacing RAM is easy. You pull out the damaged chip and carefully insert a new one. In laptops, the RAM stick is inserted and pulled out at an upward angle. Those. you insert the RAM diagonally, and then press it from the top until it clicks. And if you release the limiters, the microcircuit itself will “jump” to the top.
If you have a laptop with non-functional RAM, then it is better to immediately take it with you to the store. There you can ask a consultant to install RAM in your laptop yourself if you are afraid. In addition, you can immediately test the operation of the new RAM stick by taking with you a flash drive with Memtest86+.
conclusions
If you don’t understand something or have any questions, leave them in the comments to this article.
But, in general, testing and replacing RAM is not that difficult. It’s just that ignorance is scary, and therefore the main thing is to cope with fear. After all, computers and laptops are designed as logically and simply as possible, as surprising as it may seem.

Laptop, simple games, online games, browsers, etc. When starting up, the laptop freezes and does not respond to any commands other than turn it off, what is the reason?
Hello. This morning, turning on the computer, it beeps long and repeatedly. Is this RAM? Thank you
When I start the computer, a blue screen "Eror: 0x0000007E" crashes, I think this is a problem with the RAM, although I installed it half a year ago
Hello, it beeps 3 times when starting up.. All contacts were trusted, the video card is working.. 2 RAM strips, turned on one at a time and changed slots... Before this it started normally without problems.. What could be the problem, the screen does not react at all ..

Hello, I have such a problem, I was sitting playing with a laptop without a battery and accidentally pulled out the power cord from the socket, it turned off and won’t turn on, the Caps lock key flashes three times, this is a faulty memory module, I replaced the RAM, but there’s no point, everything is the same, tell me what to do?? ? Thank you very much!!!
The second RAM slot in the Lenovo g505 laptop does not work, I insert the RAM, turn on the laptop, the laptop turns on, the screen is black, what is the problem, explain who knows
The text is quite tolerable, but the RAM strip itself is not a microcircuit, but a circuit (or board), and the microcircuits are those square black things on it.
Good day. I have the following problem: Toshiba laptop - when starting games after some time (10-30 minutes. Sometimes more), the system just stops and does not respond to anything. The same problem occurs when you watch movies online. Tell me what could be the reason
Dude, you're awesome, you helped me out
Good afternoon This question is overdue. I have 4 DDR2 sticks, 2 of 1 gig, 2 of 2 gig, despite the fact that they are from the same manufacturer and the same frequency. if you put them separately (2 by 2/2 by 1), everything works, but only on the mother’s yellow slots. and when installed in different slots or installing 4 strips at once, some kind of failure occurs, the system unit beeps incessantly and does not load the system. What to do?
Thanks for the answer, a situation just arose, we were doing repairs, people came two months later and claim that we supposedly replaced the RAM) so I’m trying to figure out what’s what))))) the laptop was flooded))
Pavel, no, this is hardly possible. The volume cannot change like that, even if the sectors are damaged. It is quite possible that your equipment is reserving some memory. Go to Task Manager - Resource Monitor, and see how much is reserved by the equipment.
Hello, the question is, can the RAM partially fail and show 1 gig instead of 4 gigs, for example, is this even possible???
Hello! Please tell me, my RAM is definitely working, as it was tested on other PCs (Intel), but when I insert it into my PC (Intel), I get a black screen and one long squeak that repeats, which indicates a faulty RAM. I put the dies one at a time and different slots, the same 1 long squeak. Also on the motherboard there are 2 swollen capacitors near the processor socket above it and on the left, could this be the cause of the malfunction? Or is it a matter of RAM slots? I hope I explained it clearly! Thank you in advance!
Question: Computer does not work with new RAM
Good day to all.
Help me, please, figure out what's wrong. A week ago I bought myself two Kingston KVR16N11S8/4-SP 4Gb RAM sticks from the online store (Brand Star). I was very “lucky”, on the day of ordering they were in the store’s warehouse, I dropped everything I was doing in joy and went to the store, as soon as I bought them, I flew out of the store with a feeling of euphoria and almost ran home with them. With this feeling of joy, I quickly disassembled my computer, pulled out the old planks, carefully placed them on the shelf and decided that I would take them to the dacha to use the old computer. I installed the new ones, assembled the computer, set it up, with a smile from ear to ear, sat comfortably in a chair, pressed the power button... and then the feeling of joy immediately flew into oblivion, the smile slipped from my bewildered face, somewhere on the floor. The computer rebooted cyclically, preventing me from entering the BIOS. Not understanding what it was, I disassembled the computer and installed only one new stick, with one stick the computer boots and goes into the BIOS, the computer boots only up to the Windows logo and reboots again and again in the same place. Having decided that the problem was in the OS, I found my old flash drive, for such cases, and began to reinstall Windows, set all the parameters in the BIOS, booted from the flash drive, boot logo and bam! Reboot. I set the timings (11-11-11-24)… Nothing works. He spat out of anger and installed the old planks. I turned on the computer, saw the desktop, turned off the computer. Dear friends and comrades, tell me how to launch this damned new RAM?

What is a laptop? It's a portable laptop that works equally well anywhere and on any surface.
Sometimes this feature plays a cruel joke on the device. Due to the abundance of dust in the air, the laptop heats up and does not turn off.
The general layout looks like this:
The diagram, which is typical for the vast majority of devices, shows where the key components are located:
1) central cooler;
These elements are responsible for the performance and speed of work in general. If the laptop, over time, begins to overheat and slow down, then the matter is not limited to reinstalling the OS.
The problem is most often hardware. In other words, the laptop is full of dust that needs to be cleaned.
Dust in the system
Important! Before disassembling your laptop, be sure to watch relevant videos on the Internet. They describe in detail the sequence of removing components, talk about the pitfalls of assembly, secret plugs and more.
A dusty cooler is often very noisy and annoying. It looks like this:
As you can see, it is simply unable to draw in air, since the radiator is simply clogged.
Here's the big picture:
All dust is carefully blown out, after which the board elements are carefully cleaned with a soft bristle brush so as not to damage the delicate parts of the boards and microcircuits.
In the vast majority of cases, regular cleaning saves you from many problems, and the machine starts working as before.
Thermal paste
There are times when regular cleaning does not give the desired effect. Most likely, the thermal paste in the system has simply dried out due to elevated temperatures of the processor and video adapter.
As a result, the laptop heats up.
What is this paste?
This is a multi-component composition, which is a “layer” between the central computing chip and the cooling surface to which the heat pipes are connected.
It prevents the elements from overheating due to their special composition.
In the screenshot, the cooling plates look like this:
Well, this is the appearance of the processor with a dried layer of paste.
You need to clean off the old “cooler” very carefully, never using sharp objects.
Otherwise, you can damage the entire structure of the central chip or video card, which can lead to more serious damage.
Gently scrape off the hardened compound using a wooden or plastic scraper, and clean off any remaining residue using a cotton pad soaked in acetone.
Nail polish remover will also work. This will also degrease the surface.
The thermal paste looks like this:
To apply a new layer, squeeze a small amount of the composition from the tube and, using a plastic card, carefully distribute the contents over the entire surface of the chip.
The layer should not exceed 1 mm. Otherwise, the cooling system plate will not fit tightly to the elements, and the paste itself will dry out quickly.
If this doesn't help either:
You have cleaned the contents of your laptop from dust, changed the paste to fresh one, but the problem is still not solved. First of all, pay attention to the operation of the cooler.
It is quite possible that its service life has already expired and the fan needs to be replaced.
There are also laptop models that initially become very hot after prolonged “hard work”: video editing, graphic editors and other resource-intensive applications.
Or the cooling design is thought out very mediocrely.
Another option is a factory defect.
Preventing overheating
To protect yourself from dust getting inside the system, just follow a few simple rules:
1) do not place the laptop on the sofa or other soft surfaces;
2) periodically clean the ventilation system;
3) avoid dusty rooms;
4) regularly wipe the desktop on which the computer rests.
If you are not satisfied with the standard cooling, purchase an additional stand that will provide a more intense flow of cold air. It looks like this:
Its design has one or two large-diameter coolers that blow air over the lower area of the device.
Test software
The temperature regime of key components can be monitored not only tactilely by placing your hand on the laptop lid, but also programmatically.
Let's look at the example of the last representative. To do this, you need to download the product, fortunately it is distributed free of charge, but only for 30 days.
After the trial period, you will need to enter a license key. But the trial version also copes with its tasks.
After installation, we launch and see this picture:
To find out the temperature conditions of the processor and other elements, double-click on “My Computer”, and select “Sensors” from the drop-down list:
The screen displays current information about the current state of the hardware. It is updated in real time, so all data will always be up to date.
If the temperature exceeds 60–65 degrees, this is a reason to think about it and take appropriate measures.
Or turn off the laptop for a while so that it has time to cool completely.
