A common but frightening problem for users is when the computer turns on, but the operating system does not start. At the same time, the coolers work, the system unit makes noise, but the greeting and desktop are not visible. In fact, the recovery process can be done independently, and it is not as long and complicated as it seems at first glance.
Reasons why your computer won't boot
Malfunctions look different:
- black screen with inscriptions - physical or system errors;
- blue screen - problems with RAM or drivers.
There are malfunctions on different computers: Lenovo, Samsung, Msi, Asus and so on.
There are two types of reasons:
- Physical- due to the computer hardware: rusty contacts on the boards, broken wires, poorly inserted video card, damaged hard drive, dried out thermal paste, dusty processor. There may be very simple reasons, for example, the monitor is not connected.
- Software- the mathematical algorithm of the system is broken: incompatible drivers, viruses are installed, the user accidentally deleted files necessary for work, Windows is out of order, problems with the video driver.
Safe mode
When you simply restart the computer, pressing the Restart button on the system unit automatically restores the system.
If this does not help and the operating system does not start loading, it is advisable to turn to Safe Mode.
This is a way of operating a computer when it loads a list of necessary components without unnecessary elements.
- Remove all information media from the computer: flash drives and disks.
- In versions of Windows 7 / Vista / Windows xp / 2000 / ME / 98 / 95 - immediately after turning on, press F8. In Windows 8 / Server 2012 / Server 2012 R2 / 10 / Server 2016 - a combination of Shift and F8 at the same time.
- Select Safe Mode.
- Sign in.
F8 restores the version of the operating system to the previous changes.
Example
You can load the Last Known Good Configuration of Windows 7 like this: F8 or Del - Last Known Good Configuration (Advanced).
The mouse does not work in this mode; control occurs through the up-down and Enter buttons.
Damaged HAL.dll
The following steps will help fix the error when the computer reports that the HAL.dll file is damaged or missing, and restore the operation of the OS:
Startup recovery
Checking the monitor, components, connections
The external condition of the device is important.
Perhaps the reason is hidden in external damage:
After turning on the computer, a squeak follows - a Bios signal. In normal condition, this is one short “squeak” and the computer boots. If there is a malfunction, the sound changes. It is important to know the name of Bios and count the number of signals. This way you can figure out the problem using the signals.
Video card driver conflict
The computer cannot turn on due to installed video drivers. In this case, go to Safe Mode - Start - Control Panel - Device Manager - Video adapters - Disable/Update drivers (program conflicts are visible here in the Properties - Resources tab).
In some cases, after updating the drivers, the problem disappears.
Removing programs that block OS loading
From time to time, programs that conflict with Windows cause a malfunction. It is advisable to correct the situation through Safe Mode:
Start - Programs and Features - Uninstall a program - Uninstall.
You can delete in Safe Mode using CCleaner.
Disabling unnecessary Startup items
Safe Mode - Start - In the Start command line, enter msconfig.exe and press Enter - In System Configuration there are 5 tabs:
If the problem disappears, you need to go into Safe Mode and add one program at a time to startup in the “Services” list and restart the computer in normal mode.
As soon as the problem returns after adding another program to startup, the root has been found, but this program must be disabled, updated, or deleted altogether.
To enter the normal Windows operating mode: In the “Start” menu, write “msconfig.exe” and press Enter - System Configuration - General - place the checkbox on “Normal Startup” - Click OK and restart the computer.
Reverting the system to working condition
Via F8 go to the menu.
Infinite reboot
The reason that a computer or laptop does not boot beyond the manufacturer's screensaver is an initialization failure, an emergency power outage, or a full disk with files (movies, photos, etc.).
When the computer turns on again after “Welcome”, you need to:
- restart your computer several times;
- hold down F8 - the Advanced Boot Options window will appear - go to Repair Your Computer - Enter
- if the endless startup to the logo continues: Safe Mode - My Computer - drive C - copy and move files to D.
If the startup repair tool cannot automatically restore the system, you need the help of removable media.
Using a Live CD (Boot Disk)
The boot disk with the image is the second operating system. It contains a recovery console and will help in solving the problem.
Disc functions:
- diagnostics;
- virus checking;
- useful utilities.
Many errors, for example, 0xc0000098 when starting Windows 7 (problem with starting files), are solved using boot disks.
Boot Manager Recovery
If there is an initialization error, the system does not see the hard drive. You need to start from the boot disk.
Press R - the console appears - enter “chkdsk c:/f/r” and press Enter - then enter “Bootrec.exe / FixMbr” and Enter - then “Bootrec.exe / FixBoot”.
So the commands restored the resume bootloader.
Overwriting the sector Bootrec.exe/RebuildBcd will work if the hard disk is intact.
If “NTLDR is missing” (file access is not complete), it is advisable to try to restore boot records. If this does not help, copy the file from the disk to the system partition with the command: E:\i386>copy ntldr C:\ - Enter, reboot and the system is restored.
MbrFix utility
The program is included in Hiren's BootCD. After starting MbrFix, enter into the command line: MbrFix.exe /drive 0 fixmbr/ win 10
The described option is suitable for Windows 10. Helps if the boot manager is missing or damaged.
4MRescureKi
Includes services for copying data, preparing for reinstallation, diagnosing problems in a hard drive, and checking for viruses. Works on Windows and Linux.
Viruses
Malicious programs are also the reason why the monitor stopped turning on. It is necessary to detect the infection and clean the device. It happens that a virus contains a game or a picture from the Internet. An anti-virus scanner is required, which is loaded before the operating system runs.
Antiviruses on removable media are good: disks and flash drives. They have their own boot records and menu interface. For example, Avast and Kaspersky are excellent at resuscitating “sick” files.
Reinstalling the system
If the previous methods have been tried but failed to fix the problem, reinstalling the operating system is an option to solve the problem.
Black screen when reinstalling Windows
The reasons for this situation are:
- Unsuitable Windows, in this case you need a different operating system.
- Bad sectors of the hard drive, damage to the storage medium from which the OS is installed.
- It is recommended to install the operating system on another partition of the hard drive.
The hard drive has failed: how to determine and what to do
If you suspect that your hard drive is not working, it is important to carry out diagnostics. If you format it, the saved files will be lost.
It is advisable to check the hard drive in several ways:
Signs that the hard drive is completely broken:
Useful video
If the system unit does not turn on, do not panic. Let's look at the reasons and I will tell you what you need to do to solve this problem if possible and also consider different options for solving it.
The first thing you need to pay attention to:
- Do other electrical appliances work in the outlet that the computer is plugged into?
- Make sure that the cable that goes from the PC to the outlet is not pulled out or inserted halfway.
- Also - in your system unit, there is a power supply at the back and there is an on and off button on it. So check that it is turned on. I myself had such a case: maybe the cable caught it, or when I moved the unit, the button switched to the off position and the computer “doesn’t work.”
Important: do not confuse with the 127-220 volt switch button
Don't touch her!
You may have recently installed new memory or any other new device, sometimes this is the problem. Remove it and try to start your computer again.
My computer won't start: check the power supply
The power supply in your computer can also cause problems. Few people have a second power supply that can be installed for testing. The first thing you need to check is the fuse in the power supply, it may need to be replaced. For those who don't know what it looks like, I'm attaching a photo.
Not all power supplies have a fuse
If the fuse is good and the computer does not start and shows no signs of life, it may be necessary to replace the power supply. To check, it is best to take the power supply from another computer - you must be sure that it works. Thus, we put a good power supply into the computer in which we have diagnosed a problem. If the computer starts after replacing the power supply, you can be sure that it was the cause. If the computer still does not turn on, then the problem may be in other components of the PC.
Unfortunately, it may also be that the old power supply caused more damage due to overvoltage - for this reason, I do not recommend installing a power supply from a non-working PC to a working one to ensure its functionality. Because if something shorts out in the power supply, then you can ruin your work computer.
I also do not recommend taking working components from another computer and trying to install them in your own. Because if there is a problem with the power supply or motherboard (short circuit or other breakdown), there is a certain risk of damaging working devices.
It is here that it is appropriate to note that when you buy a computer, it is important that the power supply is of good quality.
Every time you carry out any work on the computer, turn off the power. This is necessary for your safety and to avoid short-circuiting anything inside the system unit!
We check components for functionality
If the computer does not start, you should disconnect the power supply: the hard drive, DVD or CD drive, remove the DDR strips, video card. Remove flash drives and other equipment from USB ports, disconnect the keyboard and mouse. This way we limit the number of potential faults.
Now try to insert the DDR stick; before doing this, wipe the contacts on the memory stick with an eraser.
If the computer starts to boot, try inserting the remaining components one by one and connecting the hard drive, drive, etc. When you connect another device and the computer does not start, it means it is not working properly.
Check the connection of the processor cooler to the power supply; if it is disconnected, the protection may be triggered and the computer will not start.
Bios or battery is dead
Every motherboard has a battery. Its task is to provide power to the memory in which the BIOS settings are stored. When its service life comes to an end, the time on your PC may reset, errors may occur during startup, all this indirectly points to the battery. Or it may not manifest itself at all and, as in our case, the computer simply does not start.
You can check the battery using a tester; if there is none, then install a new one.
Checking DDR memory
RAM memory can also cause problems, especially in older computers. Signs can be identified by the sound the computer makes. Sounds associated with RAM failure vary and depend on the motherboard manufacturer. You can also manually diagnose the problem. It is necessary to unscrew the cover of the PC case and find the RAM.
There are usually 2-4 RAM slots on the motherboard, and they are not always all occupied. We take out all the DDR strips and insert them into the first slot one by one: insert one and try to start the computer, and so on for each one. If there is no result, paste everything as it was and read on.
Video card
You can also diagnose by the sound of the BIOS or if the monitor does not respond - a constant black image. However, if the computer starts without problems, i.e. The coolers are noisy, but the screen remains black - it’s worth checking the connection of the monitor to the video card (blue plug, VGA connector).
If everything is fine with the cable (it has not come out of the connector anywhere), check that the video card is seated well in the connector on the motherboard. Open the cover, then with the power off, remove the video card and insert it back, sometimes this helps.
PC overheating due to high temperature
A common problem, primarily affecting older PCs. This happens due to accumulated dust, which subsequently overheats the components and threatens the failure of the processor and video card. To prevent this, it is necessary to periodically clean the inside of the system unit from dust.
It is also important to note the need to replace the thermal paste on the processor - it is not that expensive, and replacing it lowers the temperature of the processor. As a rule, when the processor fails, the computer still starts, but the computer does not go through the POST procedure and therefore you will simply have a dark screen.
Start or Power button does not work
The principle of operation of the button is to close contacts with each other. It is not difficult to understand that the button is faulty. You may have already noticed that when you turn on the button, the button is not pressed clearly. We find a connector on the motherboard with a chip labeled power sw - two wires go from it to a button on the system unit.
Remove this chip and use a screwdriver to carefully close these two contacts for a few seconds. If the computer started to start, then the problem was in the button.
Motherboard
Sometimes there are simply failures when starting a PC, and sometimes there is a real breakdown and figuring out what it really is is not so easy at home.
Pay attention to whether there are swollen capacitors on the motherboard. They look like the picture below.
If so, it may be time to replace them. This can be done in a workshop.
If all the above solutions do not help, your motherboard or processor may be faulty. Here you need the help of a specialist - a workshop or service center. Further diagnostics and experiments on your part can only add more work to the service specialist.
We have discussed the main faults. In order to give other advice, more information is needed, so if you are interested in anything, ask in the comments.
The first step is to establish the cause of the malfunction. If the situation is such that the computer turns on, but then the operating system (OS) itself does not load, then naturally you need to dig towards the same OS.
And if the situation is that the computer does not even turn on at all, that is, it shows absolutely no signs of life, then the situation can be much worse.
A few recommendations on what to do if your computer won’t boot!
For the first case (when the computer turns on, but the OS itself does not boot).
Here, as a rule, there is a problem with system files, either they are damaged or completely lost. Try the tips below, all tips are for Windows XP:
- Use the “Load last known known configuration (with working parameters)” option. You can use it as follows: after turning on the computer, press the F8 key, a window will appear, and in it select the above-mentioned menu item.
- Enter safe mode and try to restore the computer to its previous state. To do this, when booting the computer, press the F8 key (as in the previous paragraph), select “Safe Mode”, if the system boots, go to the following path: Start -> All Programs -> Accessories -> System Tools -> System Restore. And following the wizard's prompts, try to restore an earlier working system.
- If the previous methods did not help, then I suggest you familiarize yourself with another option. This option will return your computer to working order with a 99% probability. What do we have to do? You just need to update the old system. To do this, you will need a boot disk with Windows XP. Insert the disc into the DVD-ROM, reboot, it should boot from the CD, for this you need to set the appropriate item in the BIOS, or you can call up the boot option menu with the F12 key when booting the PC and select boot from CD/DVD-ROM, but This method may not be suitable for everyone.
After booting from the CD, select "Install Windows XP" following the prompts. When a window appears notifying you that a previously installed OS has been found, press the R key. This way, the Windows installer will update the existing copy. Wait until it finishes and try to boot normally.
For the second case (when the computer does not turn on at all).
In fact, there can be a lot of reasons for this, and it can sometimes be very difficult to help in absentia in this case. And, as a rule, the reason is a malfunction of some device (motherboard, power supply, RAM, etc.). At home, especially for an inexperienced user, there is simply no way to check the functionality of a device by replacing it with a known working one. But there is a way out, although not 100%.
First, try resetting the BIOS. To do this, you need to remove the battery for a few minutes. Or close the jumper contacts to reset the BIOS. Look for a jumper next to the battery labeled Clear CMOS (possible designations: CCMOS, CL_CMOS, Clear RTC, CRTC, CLRTC, CL_RTC). If it doesn't help, read on.
Second. It is necessary to disconnect ALL devices on the computer, leaving only the motherboard connected. That is, we take out the video card, all RAM slots, disconnect the hard drive and DVD-ROM from the power supply, if there are additional devices (internal modem, sound card, etc.) we take them out, leaving only the motherboard connected to the power supply.
And now we try to turn on the computer, if it turns on, then the problem is in one of the disabled devices. Turn off the computer and try ALTERNATELY connect devices, checking the computer for functionality. First, connect the most important devices (video card, hard drive, RAM), and then the secondary ones.
Thus, if, when installing a device, the computer stops turning on, you can independently determine the faulty device. If the computer does not turn on with one motherboard, then the problem is either with the motherboard itself or with the power supply.
No matter how modern and powerful a computer you buy, over time all sorts of problems will begin with it. One of these problems is when the computer does not turn on at all. I think this problem is annoying and I would like to teach you how to solve it. I am sure that if you have been using a computer for a long time, then you have had such a problem when you press the power button on the system unit, but nothing happens or the light comes on, the cooler starts to work but immediately turns off and the computer does not show any signs of life. It may be that when you turn on the computer, it starts beeping and nothing else happens.
Today you will find out what are the reasons for this malfunction and why the computer does not turn on. In general, we continue to expand our knowledge in computer repair.
Why won't my computer turn on?
The easiest way to determine what is the cause of the problem being described is to listen to the sounds of the speaker. If the computer is not working, it will beep, that is, make sound signals, which for me personally are not very pleasant. If you hear such signals, then everything is not so bad and you can find out why the computer does not turn on. But if you don't hear any such sounds, don't be upset. Perhaps the tweeter itself is not connected to the motherboard.If the system unit has a special speaker or tweeter that came with the motherboard and remains in the box, it must be connected. You need to connect the speaker to the contacts on the motherboard. In order not to make a mistake and not to connect or disconnect unnecessary things, you need to read the instructions for the motherboard. You will definitely find the answer there.
The sounds your computer makes will depend on the BIOS manufacturer (Award, AMI, Phoenix Bios). If you don’t know what BIOS you have, then the instructions for the motherboard will again help you. If you threw away the instructions, then all the information can be found on the Internet. Even if the computer does not work, everything is fine with the phone. Enter the name of your motherboard, which you can find out by examining the motherboard itself, and look for all the information you need.
But, let's return to our topic of BIOS signals. The most common of them:
- Award or Award - Phoenix BIOS
Long repeating signals - RAM not found or not working
- AMI Bios (American Megatrends, Inc)
2, 3 or 4 short beeps – RAM problem
5 short beeps – the processor may be faulty
1 long, 3 short beeps – video card malfunction
- Phoenix Bios
2 short beeps and 1 long beep – RAM fault.
These are the most common BIOS signals that you may have. In fact, there are many more of them. You can find out about them by reading on the Internet.
And so, we can conclude, based on the popularity of sound signals, that there are also the most popular reasons why a computer does not turn on. These sources of problems include:
- Problems with 220V power supply
- The power supply is faulty
- Battery ran out
- A lot of dust
- Problems with components or cables
- Bad power button
- The motherboard is faulty.
- Now let's talk about each problem and its solution separately.
- Problems with 220V power supply.
It is also necessary to take into account the number of devices and devices that are connected through surge protectors or extension cords to one outlet. Perhaps you overloaded the outlet and the computer did not turn on due to the protection. To test this option, you need to disconnect all devices that are powered from one outlet and leave only the computer. Perhaps in this case it will work. If the network voltage is very high or low, the computer will also not turn on. Moreover, there is a high probability that it may burn out. You can check the voltage with a special device or using an incandescent light bulb by eye. The main thing is not to confuse the lamp with an energy-saving one.
If the voltage decreases, then the light bulb will shine dimmer, but if it is higher than usual, it will burn brighter. Also, at high voltage, the light bulb can light up and immediately burn out. But this verification option is not particularly safe, so it is better to get a tester.
There are times when the outlet is fully operational, but the computer still does not receive electricity. This occurs due to poor contact of the power cable. Disconnect the cable from the power supply and reconnect it as tightly as possible.
It’s stupid to remind you, but still. It is worth remembering the buttons next to the connector on the power supply. It must be turned on. Sometimes it gets so funny that you’ve already tried everything, but the computer still won’t turn on. It turns out that the button on the power supply was turned off.
But don't press any other switches. There may be an input voltage switch on your power supply. It is usually red. You can't touch him at all!!! Its purpose is to switch the input voltage level between 127 and 220V. This is done in order to use the power supply in another country where the mains voltage is 127V, such as, for example, in the USA.
Problems with the power supply.
If you are convinced that everything is in order with the power supply, then you need to start checking the next element - the power supply. After all, it is where the power goes when you turn on the computer. In most cases, it is a faulty power supply that causes a “dead” computer.
The fact is that in our country people are gradually getting used to saving on everything. And computer elements are no exception, especially if you look at how much they cost. People naturally prefer a Chinese cheap copy of the power supply.
But this position regarding the computer is generally unprofitable. Some users do not understand how important the power supply is in the computer system unit. And we are talking not only about the maximum permissible power, but also about a quality manufacturer. It’s very good if the power supply is covered with a copper basin without catching anything. In this case, you buy a new power supply, only one that is of higher quality and more reliable. And that’s it, the problem with starting the computer will be solved. But there are times when the power supply “dying” drags along some elements of the system unit, or even the entire computer. And in this case, you will have to buy a new computer. Agree, it’s scary to even read about this! But I hope it’s not like that for you everything is bad.
To check the power supply, install a known-good element into your system unit and check whether it will work. If there is no such working power supply at hand, then we will check the performance of our part. But we can’t do without a voltage tester. Such a check can only be carried out when the lights come on when the computer is turned on.
The test using a tester is simple: take any power connector and measure the voltage: between any black and red wire there should be 5V, and between black and yellow 12V.
Some power supplies, when used for a long time, acquire the effect of “sticking” of the internal protection. Pull out the cable and leave it for about 10 minutes. After that, connect the cable back and start the computer. If the computer still does not start, then you need to proceed to checking the following elements.
The battery has run out.
Every motherboard has a small 3V lithium battery. It supports volatile CMOS memory, which stores BIOS settings. On a computer that has been used for a long time or has simply been left idle for a long time, the battery will run out and all settings will be lost. A dead battery is easy to recognize. Each time you turn it on, the time will be lost. Sometimes an error occurs at startup and the BIOS asks you to enter it and resave the settings. But there are times when, due to this dead battery, the computer does not turn on at all or turns on only every other time. Again, if you have a voltage tester, you can easily check if the battery is working. If you don't have a tester, it's better to replace the battery. It is inexpensive and sold in any computer store.
The computer got dusty.
If there are already carpets of dust inside the system unit, then it is not surprising that the computer does not turn on. Do not forget that the system unit must be cleaned regularly and the thermal paste on the processor must be changed. It is best to clean with a vacuum cleaner and a brush.
Don't forget about the contacts of the RAM and boards. They also need to be cleaned. Just before this you need to completely disconnect the computer. Taking the RAM out of the slots, using a regular grater, also known as an eraser, we clean the contacts. We try, they should shine. But do it very carefully. Often there are microscopic parts located above the contacts. There is no way to touch them.
To clean the contacts of the memory slots from dust, you can use a toothbrush, shaving brush or any other brush, as long as they are of the appropriate size.
At the very end, we clean the fans and check their performance. If the fan does not work, the computer may turn off immediately after turning on. A large amount of dust in the system unit will cause the computer to overheat. Actually, because of this, the computer may not turn on, or it may constantly reboot.
The problem of components and cables.
If anyone has reached this stage of verification, then it is worth working by the method of elimination, because you never know in which particular part of the system unit the problem lies. The check should begin with those parts that are absolutely necessary to start the computer. All other elements must be disabled or completely removed from the system unit. In short, we leave the motherboard, the processor and fan connected to it, RAM, if there is no built-in video card, then we leave that too. It's also worth connecting a keyboard. If you only have one stick of RAM, then insert it into another slot. If the computer with these elements is working properly, then we begin to connect the remaining elements in turn. Next you need to connect the hard drive. By gradually connecting the elements you can find the problem area.
There is a high probability that the part of the system unit itself will be in good order, but the cable or cable may not work.
Problem with the power button.
One of the reasons why the computer does not want to work may be hidden in the start button of the system unit. Perhaps the button does not close the contacts well enough. It is clear that because of this the computer will not turn on. It is very easy to check its functionality. To do this, you need to inspect the motherboard and find the place where the wire from the front panel of the system unit case is connected. And there you can easily find the “Power” connector. Pull out the connector itself and use a screwdriver to close the two contacts. If the computer still does not turn on, go look for the problem further.
Problem with the motherboard.
If you did everything as described above and the computer does not start, then I have bad news for you - there is a problem with the motherboard. There is a high probability that you will have to replace it with a new one, but it is now oh so expensive. Yes, and you will want to change the motherboard to a newer one. Accordingly, you will have to change the processor, and then the RAM. In short, the entire system unit will undergo an upgrade. But, if you change a motherboard from the same series as yours, it must have:
- same processor socket (socket)
- required number of RAM slots, and of the same type (DDR, DDR2, DDR3...)
- interface for connecting an existing hard drive (IDE, SATA)
- a sufficient number of expansion slots for existing cards (PCI, PCE-Express)
You shouldn’t rule out repairing the motherboard, especially if it’s under warranty. But in this case, you will have to sit without a computer for a long time. From my own experience, I know that no one is in a hurry to repair the motherboard under warranty.
If there is no warranty, then you should send the motherboard for repair if the repair work does not exceed 30% of its price.
After you have independently checked the elements of the system unit and have not found a problem, there is no need to do anything yourself. You can only make it worse. You will have to call a specialist to your home so that he can “diagnose the patient.”
Actually, that's all. I’m sure our article helped you and you fixed your computer. Stay with us and learn a lot of new things.
In this article, we will look at situations in which a computer may not turn on or boot. We will also give some tips to solve such problems.
The computer won't turn on
(When you press the power button on the system unit, nothing happens: the lights don’t light up and you can’t hear the noise of running fans)
When the computer does not show any signs of working, the problem is in the hardware.
Solutions.
Step 1. First, check and rule out “inattentive” reasons:
— did you forget to turn on the button on the extension filter;
— whether the power supply toggle switch is turned off (located on the back of the system unit next to the place where the 220V cable is connected;
Step 3. If the problem is not solved, you should stop searching on your own and contact the service center!
The computer turns on but does not boot
(When you press the power button, you can hear the noise of the cooling systems, but the boot does not reach the desktop)
This symptom can be due to either hardware or software problems.
Symptoms of this problem are divided into 3 subspecies:
I. There is no image on the screen - neither the BIOS screen nor the operating system boot screen
Step 3. If the problem persists, try replacing the BIOS battery on the motherboard - type CR2032
Step 4. If the problem persists, contact the service center.
II. There is a BIOS image on the screen, but Windows OS loading is not visible.
Step 1. Turn off computer. Open the system unit and check whether the power cable and SATA cable are connected to the hard drive.
Disconnect and connect them again.
Step 2. Boot from the Windows distribution and perform a system restore.

How to enter Windows recovery mode: article will be added later
Step 3. Reinstall the system
Step 4. If the problem persists or periodically recurs even after reinstalling the system, contact a service center.
- Do not place the system unit on the floor or other particularly dusty surfaces. Try to place the unit on a stand or in a special niche on a computer desk.
- Clean the room more often, including wet cleaning. The less dust there is around the computer, the less often you will have to clean the computer from dust.
- Clean the system unit at least once every six months. We recommend that you trust the cleaning of the system unit to specialists. However, if you consider yourself an advanced user, we recommend reading the article on cleaning your computer.
- At least once every 3 years, replace the thermal paste on the central processor, video card and chipsets that have radiators.
- Once every 5 years, we strongly recommend replacing the BIOS battery (type CR2032), even if the computer is working normally. It's better to do this in advance than it will be an unpleasant surprise at the wrong time.
