Why doesn't the computer start? Vikoristana installation disk. The computer does not respond to the start button

If, after pressing the power button, the PC does not make the desired sound, the fans do not spin, and the LED indicators do not light up, first of all, take a closer look at the life cycle, and check it yourself to ensure that your connections are reliably connected. with socket and plug near the block , and also the life block is in the “ON” position.

Also, make sure you don’t miss out on the life in the motherboard sockets, which can happen to desktop PCs under the influence of non-professionals or strong vibrations. Now open the housing cover with your left hand and observe how the cables from the life block to the motherboard are correctly connected. Look at the wide 24-pin connector and the 12-volt or eight-pin connector on the additional life processor and look at them. If burnt contacts on the right are detected, there may be a loss of voltage or a malfunction of the life block. It is entirely possible that all system components have failed, which may require the purchase of a new computer.


Button malfunction.
Short-circuit the faulty contacts of the power button on the motherboard using an additional clip to check the malfunction of the power button on the computer case.

If there is everything on the side, check that the life buttons are correctly connected and reconnected on the case to the motherboard and the stinks are easy - small double-pin connectors are carefully connected to the contact pins c. Turn off the “Reset” button and try to turn off the computer (as this means, the reset button is faulty and must remain disabled).

If this does not help, press the live button. Then, if the system can be started by shorting both contacts, for example, using a violin, it means that the power button is faulty. In this situation, connect the restart button and use it as a “UVIMK/VIMK” jumper. Otherwise, you will have to take the system unit to the workshop for diagnostics.

2 PCs work, but the monitor goes dark

If the cooler and LED indicators are working, but the image on the monitor screen is not displayed and turns black, turn over the main part of the screen, and also turn over so that the OSD menu for adjusting the display is displayed when you press and dedicated keys. If not, then the monitor is faulty - you can check it by temporarily connecting another display (or a TV via an additional HDMI cable).


When the on-screen menu is displayed, switch the inputs behind the Source button or the corresponding item in the menu until the required input connection is set. Then switch the display modes on your laptop by pressing the “Win” key and pressing “P” - this allows you to switch to the next one of the modes. Wait a few seconds and switch several times to check whether images are displayed in one mode. If this does not bring results, replace the cable for the monitor and try another available interface (for example, HDMI or VGA instead of DVI) to detect any problems with the connectors or cable.

Find out that the most difficult way is to check whether the video card is installed or replaced (at first, the video card may be old or out of date). Since all these attempts are not successful, there is obviously another problem with the hardware, which you can diagnose with the help of further actions.

3 BIOS does not start/freezes

A flickering cursor on the screen when starting the PC or a BIOS that freezes for an hour during initialization may indicate various problems with hardware security. First of all, make sure that all connectors (for example, a CPU cooler) are correctly connected to the motherboard and that all coolers are working. Whenever necessary, replace faulty ones. The motherboard speaker displays important information such as sound signals, the meaning of which is explained by the speaker of the motherboard speaker. However, this requires that this small speaker be properly connected to the “Speaker” connector of the motherboard (turn it over or use a special POST card for diagnostics).

These signs may indicate that the BIOS Setup has not been adjusted correctly - this problem can easily be resolved by resetting it to factory settings. The procedure is described in the guide before the motherboard. For most situations, it is necessary to set the jumper marked Clear CMOS on the board to the lowered position for a few seconds when the computer is turned on, and then move it back.

The lack of image on the screen may indicate a malfunction of the monitor, PC or cable between them

The next step is RAM: turn over the module correctly (if only one is installed, try inserting another slot) and replace the faulty one.

Then turn on all hardware that is not important for the operation of the PC, from USB, PCIe, and other computer connectors. As soon as this wine starts, step by step connect everything back - and try until you find the culprit.

If nothing has helped, it’s possible that the motherboard and/or central processor are damaged, and you need to get ready before adding new devices.


4 Windows won't start

Does the computer go through the BIOS initialization stage, but does it notify you that the required disk is not found? Before you do so, make sure that the SATA power cable and the data cable of your hard drive or solid state drive are connected correctly. Then try connecting the drive to another cable and one of the other ports. It does not appear in the BIOS Setup/UEFI (to check, press “Del” when the computer is running, go to the “Advanced Chipset Features” section or something similar, and see if the drive is recognized on one of the channels) to SATA) , try connecting the HDD via the SATA interface or a USB case to another computer. However, this does not mean that there will be a discrepancy, and, above all, the data can only be updated by a professional service for a high price.

If the disk appears in BIOS Setup or is still readable on another computer, but is no longer usable, you must immediately run the update system and back up your data due to the risk of file system damage or Paratnogo zboyu. Then update your operating system: download your computer from the Windows installation media (insert a DVD or USB drive, press “F12” or a similar key in the download menu) take nose). Launch command row. Then enter: "bootrec /fixMBR" "Enter", "bootrec/fixBoot", "Enter". If this does not help, restart the console and enter bootrec /rebuildBCD, Enter. However, it is likely that your Windows desktop suffered from damage to the file system or hard drive, which needs to be reinserted - especially to a new disk, since the remains of the old one will no longer be reliable after the failure.

5 Unable to login to Windows


Driver problems.
If Windows does not start, try uninstalling bad drivers or dismantling hardware in safe mode.

If Windows starts to get busy and you can’t finish it, you have two options: or take a three-hour break (for example, Windows updates can jam dozens of devices in the system, so as to kill everything operations in case of re-invalidation), or, if Click on Nothing has been reported in a year or the problem is not related to Windows updates. This mode is proposed as an option after rapt recovery. In other cases, immediately after launching, press “F8” (Windows 10 - Shift + F8). If problems with updates affect the startup, Windows says they are, after which the system may be forced into default mode. In addition, in this mode you can update or uninstall software and drivers whose installation probably caused the problem.

Otherwise, launch the “System Configuration” tool in safe mode, on the “Services” tab, activate the “Do not display Microsoft services” option and uncheck all other services that are displayed.

Now enable on the “System Startup” tab (Windows 7) or in the Task Manager on the “Auto-enable” tab (Windows 8 and 10) all programs that will be auto-enabled. If this does not help, remove all unnecessary devices. As a last resort, before starting the reinstallation, run the command line in safe mode under the name of the administrator (type "cmd" in the search field of the "Start" menu, right-click on "cmd.exe" and select "Run as names" and administrator") and Enter "sfc /scannow" - this will allow you to check all system files and, if necessary, replace them with the original ones.

The problem situation, if the PC system unit does not connect, does not happen so often. Therefore, the koristuvach, who has paid for everything, has no great regret for the versatility of such orders. And the range of reasons for such a malfunction may be even more numerous.

First, turn on the tester, turn on the power supply, and then make decisions about further actions after receiving a response.

  • Marvel at the documentation - if the warranty has not yet expired, take the system unit to the master.
  • How expensive is your computer and how long has it been in your power? If you have a new road, it’s better not to risk doing independent repairs.
  • Do you consider yourself a technically competent professional? If not, we’ll go back to the service center.

Most of all, the idea of ​​​​restarting on your own, why the system unit does not turn on, was blamed on the fact that your computer is old, and there is nothing left on the card. There are also terminological references on the Internet. Then try a simple, but logical way.

What are the symptoms of malfunction?

What exactly is not working? Did you try to launch any emotions? Is it possible that the patient has seen such pitiful sounds and is anxious to reveal his illness?

This can be understood from the system signals. For skin types of PC, the sound alarm will be different. That's why you'll marvel at the technical description.

If the desktop turns on, and then turns on again - everything is done, the life unit is working, and the electrics are at a standstill. There are no reactions - turn off the light and radio in the room to change the connection so that your electricity is not turned off for chronic non-payment.

The next stage is checking all the electrical equipment from the socket to the device. Do you have no desire for an uninterrupted life? If it works, but the PC does not boot up, there may be a malfunction in the DBZ robot. Try re-enchanting Yogo.

Check the integrity of the cables so that they are securely inserted into the sockets. If the intermediate distributor is protected from re-vantage, make sure that you do not connect the adapter through those that have a lot of companions at once.

Often the reason for the failure of the device is the failure of the cooling fan of the living unit. Perhaps the shovels fell off. Open it and take a visual look.

Are the capacitors swelling? Since the computer is too old, the electricity may have dried out. The price doesn’t seem to be obvious for a long time. It is possible to reliably contact the information center by simply replacing it with a clearly robotic one. Voltage testing does not provide a guarantee.

If you have recently added some modules to your PC, you have upgraded, perhaps the old life block is no longer tired. To check, try to immediately turn off all those that were recently connected.

If there are any duplicated modules, for example - two hard drives, a lot of RAM sticks, you can sequentially turn on duplicates and start turning on the device again. If the speech has been transferred, at which stage everything can be connected. Then you were spared - you just need to add more power to the power supply.

A common problem is a malfunction of the Start button. The contacts wear out due to frequent switching on, and the wires simply cannot be found on the PC one time. Try to carefully close the contacts of the start button using twist. The problem is that the computer may display Windows.

System problems

As soon as the desktop starts up, every hour it works, notifications flash on the screen, and then everything freezes - it looks like the blocks in the middle of the system have gone wrong.

Or there is a thick saw ball accumulated in the middle of the computer case. Or the contacts of the connections have oxidized. If the saw works well, pick up a soft pencil, a vacuum cleaner, and start cleaning up the interior.

After this, disconnect the contactor and use another school eraser to clean the copper contacts from oxides and carbon deposits. Don’t turn everything on at once, otherwise you’ll forget where everything is connected. Remove and clean the contactors one by one.

It is best to re-close the device after disassembling and cleaning the liquid connection and try to soak it in. This way it will be possible to accurately determine who is at fault.

Highlight all applications

Now you can fix the faulty module. Turn on absolutely everything, except for the most essential, without which the computer absolutely cannot function:

  1. Living block.
  2. Motherboard.
  3. One RAM panel.

If the PC requests, it means that exactly one of the blocks is faulty or the connections are incorrect. After that, start inserting the blocks one by one and try to stick them in. As soon as the desktop stops starting, there is a faulty module and a replacement is required.

If, after you have turned on all the applications, the computer still does not want to start, it is highly probable that the motherboard itself is faulty. Look at the board carefully. The presence of capacitors that are swollen indicates a malfunction. The cost of repairing a motherboard is much lower than the cost of buying a new one. Then you can send the motherboard in for repair.

Another reason why the computer does not turn on is the system battery. Even if the computer starts working, the hour just keeps ticking. If your computer's system date was not fixed during the rest of the day and was re-adjusted after each session, the battery has run out. Occasionally, the battery runs out and can cause the computer to not turn on at all. Try putting a new battery in front.

If the Windows user has a problem, if Windows 7 does not start on the computer or laptop, this article will help you solve this difficult problem. Launching Windows 7 is sometimes impossible due to system crashes after hardware problems, incorrectly installed software, useless utilities, etc.

But the biggest reason why some people don’t like Windows 7 lies in the operating system itself.

Solving the problem

At the end of the day, if all the initial stages of launching Windows 7 on a PC or in a laptop finish normally, but Windows 7 still doesn’t start until the end, then the koristuvachs are about to begin to put it in a dark place. I want to be clear about the nutritional instructions: “What should I do?” Don’t show up to newbies. If the cause of the problem is a hardware failure, then check the signal from the speaker of a laptop or desktop computer during the POST test. If this is the case, then you won’t be able to launch the OS.

If the problem is of a software nature, the process begins at the installation stage of Windows 7, which means that the user is faced with a wide-ranging problem that depends on the algorithm of standard actions.

Instructions before action

It is necessary to select the OS update. During the process of starting the PC, if Windows 7 does not start, the system often recommends that the owner of the computer or laptop select the settings option. If I feel like such a proposition is not found, then the user can independently open this menu by clicking on the “F8” button. Then they will publish the update of the normal attraction of “Simka”.


What should you do if the above instructions did not cause a problem?

To resolve the problem, if Windows 7 does not start, you need to install the CD with the OS:

  1. Insert the installation disk into the PC drive;
  2. Start the system from the disk (the BIOS must have the default option to enable the system from the media installed);
  3. In the window that appears, click on “Stop update functions that solve problems with installed OS” and click on “Next”;
  4. Then, in the “OS update settings” menu, click on “Startup update”;
  5. Check until the analysis of the system is completed and the causes of failures are identified;
  6. Viconati re-invented PC;
  7. The BIOS allows you to start the system from the hard drive ( When exiting the BIOS, you will need to save any adjustments you made.);
  8. I'm starting to restart my computer;
  9. Ready! Now it's normal for Windows 7 to become addicted.

For additional help from the team row

If I was unable to update Windows from the installed installation disk, there is another way to do this through the command line.

From the very beginning you need to work the steps indicated in the paragraph about updating the normal attraction of “Simka”. The only change is that in the “System Update Options” menu you now need to specify the “Command Row” section.


Why bother if you haven’t achieved a positive result by following the instructions?

Since it was not possible to achieve success and has already violated these parts of the statistics, it means that the problem cannot be classified as a typical failure of a modern OS distribution. You will need to continue working in Windows Safe Mode. It is recommended to perform an analysis of disk “Z” before bad clusters appear.

To enter safe mode, you need to click on the following steps:


Why are preventive visits important?

Windows 7 has a special system that can create special reference points that can be updated for different needs. Having stagnated this function of the defense, it is now possible to easily turn the operating system back to its original state.

For example, in case of failures as a result of incorrect installation of add-ons, drivers and other utilities on the codec kit, the fixes are shown by making adjustments to the Registry.

Please note that in “Simka” it is possible to allocate fixed memory on the hard drive specifically for such protection of the operating system. In Windows 7, you can independently configure the protection of a number of system data and files, or you can do it separately.

The “computer won’t turn on” question is not asked - one of the highest rated on the Internet. Sooner or later, any kind of correspondent may be shut out of the situation if his computer is categorically encouraged to make contact. The reasons for this may be very different, but even worse, you can correct the situation and “revive” the computer.

Please note that immediately attempting to repair your computer may lead to the problem being resolved. Before proceeding, it is necessary to understand the nature and location of the breakdown.

Because the computer doesn't start up

In this case, the computer will ignore the activation test, so that when the Power button is pressed, the fans will not start, the indicators will not light up, and there will be no sound signals. Let's take a look at the main reasons and order of actions, directly based on the elimination of problems.

  • The problem is with electricity. Check whether there is electricity in the booth, or a socket, or a life switch. Inspect the power cord for damage or failure to connect to the socket in the system unit.
  • Malfunction of the life block. Once the voltage has been cut, the internal protection mechanism can be activated. Pull the life cord out of the socket, fasten 5 strands and insert it back. If the problem occurs due to a sudden interruption in life, the computer will freeze.
  • Overheating of the processor or video card. In this case, it is necessary to let the computer cool down at any time.
  • Drank. Clean the computer using a saw using a vacuum cleaner or pencil cleaner. Be careful when cleaning, do not get microscopic parts.
  • The power button is broken. Find the Power connector on the motherboard, it is located at the place where the wires are connected to the front panel of the case. Remove the socket and carefully connect the two contacts with a screwdriver.


  • The CMOS battery is dead. If you previously had problems starting your computer, for example, it turned on every once in a while, or you experienced constant problems with the system clock, then your battery is probably out of order. In this case, simply replace it with a new one.


The computer switches on, but does not start

Failures to start up can appear in a blue or black screen when the computer is turned on, in sound signals that are not characteristic of the initial start-up, in the absence of alarms when starting the robot, and so on.

  • Black monitor screen. Reasons for the malfunction:
  1. Problems with the video card. Make sure you are connected to the computer correctly, and if so, it may have overheated. Check in every hour and your computer, which will cover everything, will allow you to sleep without interruption.
  2. The problem is with the monitor itself. Connect another monitor to the computer. Or, alternatively, connect another device to the monitor.
  • Blue monitor screen. You can fix the problem by going into safe mode, uninstalling new drivers, removing infected files, or restoring the system to the previous update point.


  • Messages to replace the screen. Apparently, the hard drive and the operating system are not stable. Make sure the hard drive is properly connected to the motherboard. Since everything is connected, more than anything else, you will have to replace the hard drive or reinstall the system.


The most common causes of computer breakdowns are the main ones, but not the only ones. It is possible that the methods for correcting the situation described above did not work for you or did not help you. In addition, such manipulations, such as replacing a hard drive, require special attention, and if you are a beginner, then good decisions will be made to the service center.

Usually, the most careful computer user faces the situation when his computer inadvertently stops booting up. This may be due to various reasons - hardware, software, or due to the complex influx of these and others. How can they be revealed? What are the available ways to troubleshoot breakdowns that you are interested in on a PC?

Interpretation of breakdowns

Strictly speaking, the situation, if the computer does not turn on, and if there is no reaction to pressing the life button, rarely occurs. There are a number of reasons for this, for example, simply because there is an electrician in the apartment.

Many people understand that if the computer does not start up, there is no image on the screen, and the system unit is buzzing and the lights are on. Another interpretation of the problem is the image that prevents Windows from being installed. In this case, the computer does not turn on, so the result is the same: you cannot work on a PC. We will look at a number of scenarios with different views of the communists on the essence of the problem, which is what we are talking about.

The situation, if the computer is at all, as we have designated more, is rare. Most often, other mechanisms on the system unit still begin to work, but for a number of reasons, keeping the PC away becomes impossible. In the architecture of modern PCs, the transfer mechanism that transfers, in case of such breakdowns, the input-output system - BIOS - signals them through additional sounds similar to a squeak. There can be a lunatic stench from the speakers or from the small dynamics built into the motherboard. Let's take a look at their features.

about breakdowns

The sounds involved are divided into two types - long and short. If the computer does not turn on or beep, you need to determine the sequence of signals. Today's motherboard manufacturers often program a similar function of the microcircuits associated with the following sounds:

There is usually 1 long signal and 3 short ones, which means that the computer does not recognize the video card;

If you hear new and repeated sounds, this means there are problems with RAM;

If the speaker hears 5 short sounds, this may indicate a breakdown of the processor;

They can also be voiced for an additional 1 long signal and 3 short ones.

It is important that the difference between these and other signal formats depends on the BIOS version. What does it manifest itself in? For example, in some BIOS versions, problems with the video card are signaled by 2, 3 or 4 short signals that go on shortly. If the computer does not boot up and eats loudly, then in the Award type BIOS the interpretation of sounds may differ from the one set for the Phoenix I/O system.

Problems with energy supplies

Let's take a look at this situation if the computer does not turn on due to electrical problems. If the PC does not respond to the push button, then we first need to check the electrical system in the apartment. If this is the case, you need to check that you have not applied protection to the interstitial filter. This happens when a large number of devices are connected, especially quiet ones that require significant effort. There may be problems with the PC power cable - you need to check that the connections are correct to the power socket in the system unit, as well as to the outlet.

Since the computer does not start up when starting up, this may be due to the operator’s oversight in terms of activating the jumper in the back of the system unit. You must remove the instructions from the socket where the life cable is inserted. It is necessary that the supporting element be in the down position. Also on some PCs there is support for several types of power supply, for example, 110 and 220 volts. To work in each case, it is necessary to move the main switch to the correct position.

Problems with the life block

Another possible reason why the computer does not start up is a breakdown of the life block. Electricity in this connection is supplied to the PC normally, but the supporting component that represents this part does not work. It is not recommended to diagnose the functionality of the life block without proof of ownership - it would be better to immediately turn to the facists.

Otherwise, it may appear in such a way that it does not turn on due to a failure in the life block, which can be installed on its own. On the right is that on the block of life of the inode the internal mechanism of protection from voltage changes is generated. As soon as a strip is generated in the electrical circuit, the supporting elements in the PC system unit are required and do not allow life on the microcircuits. If the blocking is disabled, the operator must not discharge the capacitor, which is responsible for the functioning of the protection system. This is easy to do - you just need to unplug the power cord from the socket on the system unit, tick a few seconds and place it back. If the problem was with the designated defense, then the PC would be more likely to get involved.

Replace the battery

One of the possible reasons why a PC might respond to the power button is a CMOS battery that has gone bad because it is installed on the motherboard. The term of its attribution is about 5 rocks. It is completely normal that after the end of this term, they may stop functioning. It is significant that this problem does not arise immediately: it usually results from other problems with starting the PC, momentary failures in adjusting the system clock, and restarting the computer every other time.

It's easy to replace the CMOS battery - all uninformed users who don't want to permanently damage their computer through a variety of significant values ​​are called upon to do so. The element that looks like a battery, looks like a battery, but is even flatter, similar to a small coin. You can get help from different places of the mother's payment. The butt is in the photo below.

The battery can be removed using a fine twist. It’s better to take it with you to the store as a sample and ask the seller to see the same one, otherwise it was released recently.

When the “zalizo” creates a wrap

If the computer's life is not affected, problems may also occur in other hardware components of the system unit. For example, it often happens that the structure becomes deformed when pressed against the start button of the system unit. As a result, the main element simply cannot close the required contacts on the motherboard so that the computer begins to freeze. You can help the system start up manually by finding the Power connector on the motherboard and carefully closing the contacts on the new one, using additional screwing. It’s clear, in short, that it’s worth making a fake.

The PC motherboard contains a large number of capacitors, transistors and other elements that are important for the stable operation of the PC. If the computer does not turn on, the reason may be that any of the essential components are not working well. It is clear that it is possible to reveal this without further evidence. Alternatively, using the complete switch-off method, you can try to figure out this problem by checking that it is not in the power supply, not in the life block and not plugged in.

We looked at the main reasons why some PCs may not respond to the life button at all. Nowadays, depending on the situation, when the computer turns on or starts up, the picture on the screen remains the same every day, but it doesn’t give anything in terms of the prospects for using the PC.

Make noise to no avail

Let's look at the first option if the system unit is working, but the images on the screen are not visible. This situation could be due to a number of reasons.

The most advanced computer official is a problem with the video card. This is to add a sensitive component, head on, through the heat until it overheats. The video cards must have factory coolers, otherwise the focus on the main PC component may require significantly weaker cooling systems.

If the computer screen does not turn on, it is easy to check which type of device has stopped functioning. You will need to connect another monitor to your PC or connect the current display to any third-party device. There may be problems when ensuring contact between the monitor and the system unit - the wire may become twisted or, for example, touch the connector. And in this case, a defective effect can be avoided - another monitor on the computer that is being verified does not work through those that were clogged with video on the system unit, and the streaming display does not function on a third-party device ї through observations in its elements.

Another reason for the situation, if the computer does not turn on (the coolers are running, but nothing is displayed on the screen), is problems on the motherboard. As we have defined the product, it has a large number of components. Most of them are responsible for processing video signals.

Why isn't Windows interested?

What can the situation mean if there is an image on the screen? Those that, at a minimum, a PC has a functioning processor, RAM, video card and main chips. The computer is technically ready for work, but I just can’t start the operating system. Scenarios that represent a breakdown may be like this.

It is possible that a picture appears in front of the student’s eyes: the computer does not turn on (the screen is working), and this shows that instead of looking at Windows, the writing on the screen appears. Whose appearance is very important, what type of information is to squeal about what the stink is. There may be a number of basic options here.

There may be problems with the hard drive. In this window you will see the message Reboot and Select Proper Boot Device or Disk Boot Failure.

It is possible that Windows files have been corrupted for any reason, for example, through a computer virus. In this case, the command row may appear on the screen, otherwise the graphical components of the OS will not be displayed. It is significant that whenever Windows crashes, the same messages appear on the monitor that sometimes have problems with the disk.

In both scenarios, the problem may become serious, and you may need to reinstall the OS or replace the hard drive. But it turns out that this is a very minor glitch, for example due to unstable contact of the hard drive connectors on the motherboard. It is easy to put it in by checking the supporting elements.

The simplest problem is that readers for magnetic magnetic noses (they want to be respected as old, but sometimes are victorious) have a floppy disk. In many PCs, the system setup, although it may not sound surprising, has the option activated, which allows the installation of the OS to start from the floppy disk itself. Without detecting an operating system on it, the computer appears without it being installed at all, and displays the latest notifications on the screen. You need to remove the floppy disk and try it again.

A similar situation occurs - the user has recently re-installed Windows or updated it with some PZ images from the backup disk and forgotten it from the device reader. The system will probably also be adjusted to start using a CD or DVD drive, and will work as long as people cannot burn a disc. Keep in mind that if there are no system files on the DVD, you will need to continue downloading from the hard drive. However, stinks may be on the nose of someone who has been hired for the crime, and you may not even suspect what’s on the right side if Windows is not installed. Therefore, when you start the PC, at some point the track will jump because the usual devices - neither bezels nor laser ones - are not located in the readers.

If Windows does not work, this may also be due to problems in the hard drive hardware. To do this, connect the hard drive to another PC as a secondary one and check which files are read from it. Before speaking, it will be a good idea to make copies of the most valuable data on another computer.

Another option is that Windows can start to get addicted, and instead of the “Desktop”, other pictures or, again, the command row will be displayed on the screen. This means that the disk is faulty, but there are problems with the operating system. In this case, with high reliability, you will need to reinstall the OS.

In case of possible problems with the startup of Windows, you may always have a valuable disk on hand. This can be a proprietary installation from Microsoft or, for example, generated by the computer manufacturer. In another location on the disk, similar devices can also be developed independently, for example, based on free Linux distributions.

Incorrect BIOS settings

It happens that the computer boots up, but does not start due to incorrect settings in the I/O system. This may be due, for example, to the fact that the user installed some new hardware component in the PC, for example, an additional RAM module, updated the video card or upgraded the processor, and the BIOS settings became unchanged.

In this case, the best option is to set the options in the I/O system according to the settings. If you need to go to the BIOS interface, you will most often need to press DEL on the PC's boot screen, then find the Set Default Settings item or the sound associated with it. Then select the Save and Exit Setup option or what to sound. After this, the I/O system will write down the changes that apply to the installation after cleaning and restart the PC. If I don’t know the problem, then the reason is that the attraction doesn’t go my way. In this case, the most optimal BIOS settings can be installed by consulting with the relevant guides.

Before speaking, in the BIOS you can correct the sequence of system power-ups based on the OS version. Most of all, we looked at a scenario in which a floppy disk placed in the middle of the reader could interfere with the startup of Windows. Settings that are considered to be previous versions are also registered in the BIOS. The stench of the Boot Sequence section or the one associated with it will grow. As a rule, these adjustments are made to vertically rank the noses that will be attracted. Most commonly, a floppy disk is used - a Floppy - and can be replaced with a HDD - a hard drive.

The working PC is affected

What should you do if there is such a situation: the computer is plugged in and doesn’t turn on? The simplest option here is, first of all, a power outage. But often the reason is something else - overheating of one or other hardware components. Most often - the processor. If the unit overheats, the system will initiate a shutdown algorithm. In this case, consider the hardware, so that it is included in the architecture of the processor itself. If the temperature of the PC's main microcircuit is programmed to a new critical level, the computer will not turn on.

There are two reasons for such a problem - a faulty or insufficiently tightened cooler, as well as dried out thermal paste - a substance that enhances the effect of the fan operation. It may be that the user has gone overboard with overclocking the processor - as a rule, this procedure increases the clock frequency of the microcircuits, which can lead to significant overheating, which may not damage the cooler.

If a computer with a processor, the temperature of which is beyond the norm, if you are interested, you need to check a little. To prevent this problem from recurring, replace the thermal paste and upgrade the cooler. On the right, it may also appear that the fan is simply cut off. And here you need to clean it. Before speaking, the aspect of hygiene is important for most PC components - not just the cooler, but the video card, motherboard, disks, and the main fan on the system unit.
