The computer turns on. The computer does not boot when I turn it on, what should I do? Checking network cables

Problematic situation when it does not turn on system unit PC, doesn't happen very often. Therefore, the user most likely does not have much experience in solving such problems. But there can be many reasons for such a malfunction.

Before arming yourself with a screwdriver and a tester, ask yourself a few questions and only after answering them, decide on further actions.

• Look at the documentation - if the warranty is still not over, take the system unit to a workshop.
• How expensive is your computer and how long have you owned it? If the equipment is expensive and fairly new, it is better not to take risks with independent repairs.
• Do you consider yourself a technically savvy user? If not, we go to the service center again.

Most likely, the idea to figure out on your own why the system unit does not turn on arose because your computer is quite old, and there is only a little money left on the card. Moreover, urgent matters on the Internet are running out. Then try to follow a simple but logical path.

What are the symptoms of a malfunction?

What specifically doesn't work? No emotions at all or were there any attempts to start? Perhaps the patient made some plaintive sounds, trying to talk about his illness?

Something can be understood from the system signals. The sound alarm will be different for each type of PC. Therefore, look in the technical description.

If the desktop turns on and then turns off again, most likely the power supply is working and there is electricity in the network. If there are no reactions at all, turn on the light or radio in the room to make sure that your electricity has not been cut off for chronic non-payment.

The next step is to check the entire path electric current from the outlet to the device. Do you have a source? uninterruptible power supply? If it works, but the PC does not turn on, the UPS may malfunction. Try rebooting it.

Check the integrity of the cables and whether they are securely inserted into the sockets. If the intermediate distributor has overload protection, see if the adapter has tripped due to too many consumers being turned on at the same time.

A common cause of device malfunction is failure of the power supply cooling fan. The blades may have fallen off. Open it and make a visual inspection.

Are the capacitors swollen? If your computer is very old, the electrolytes may have dried out. This is not always apparent by sight. You can reliably verify its serviceability only by replacing it with a known working one. Voltage testing does not provide a guarantee.

If you recently added some modules to your PC or made an upgrade, it is possible that the power of the old power supply is not enough. To check this, try temporarily disconnecting everything that was recently connected.

If there are any duplicate modules, for example, two hard drives, many slats random access memory, you can sequentially turn off duplicates and try to turn on the device again. If the problem is overload, at some stage of the outages everything should work. Then you're in luck - you just need to buy a more powerful power supply.

A common problem is a malfunction of the Start button. The contacts wear out from frequent switching on, and one day the current simply does not flow into the PC. Try to carefully close the contacts of the start button with a screwdriver. If this is the problem, the computer should start loading Windows.

System problems

If the desktop turns on, works for a while, some messages flash on the screen, and then everything turns off - it looks like the units inside the system unit have failed.

Or a thick layer of dust has accumulated inside the computer case. Or the contacts in the connectors have oxidized. If there is really a lot of dust, pick up a soft brush and vacuum cleaner and start cleaning the interior.

After this, sequentially disconnect the contactors and, using a rubber band (eraser), clean the copper contacts from oxides and carbon deposits. Do not disconnect everything at once - otherwise you will forget what should be connected where. Disconnect and clean the contactors one by one.

It is best to re-close the device after disassembling and cleaning the separated connector and try to turn it on. This way you can accurately determine the culprit of the malfunction.

Turn off everything unnecessary

Now you can start looking for the faulty module. Disable absolutely everything except the essentials, without which the computer cannot work at all:

1. Power unit.
2. Motherboard.
3. One panel of RAM.

If the PC starts working, it means that one of the units is definitely faulty or incorrectly connected. After that, start inserting blocks one by one and try to turn them on. As soon as the desktop stops starting, this is a faulty module and you need to look for a replacement for it.

If, after you have turned off everything unnecessary, the computer still does not want to turn on, there is a high probability that the motherboard itself is faulty. Inspect the board carefully. The presence of swollen capacitors indicates a malfunction. The cost of repairing a motherboard is much lower than buying a new one. Therefore, you can send the motherboard for repair.

Sometimes the reason the computer does not turn on is a dead system battery. Although, usually the computer works, the time is just constantly lost. If in recent days your computer’s system clock has not been fixed and you have to reset it after each session, the battery is low. In rare cases, a dead battery may cause the computer to not turn on at all. Try installing a new battery.

Computer users often complain that their system unit does not turn on, without providing details about the problem. Most often it turns out that we are talking about the inability to load the operating system, and not about problems with turning on the computer. When your computer won't boot due to operating system or BIOS errors, you need to look for a solution to the specific problem. However, situations are possible in which the computer does not actually turn on - that is, its loading does not even begin or immediately stops before the software starts working. There are not many reasons why this situation may arise, and below we will look at the main ones.

The computer does not respond to the power button

In most cases, the problem due to which the computer does not turn on is quite trivial - lack of electricity.

First of all, you need to make sure that the system unit (or laptop) is connected to a power source. Inspect the wire connected from the outlet to the computer power supply for mechanical damage, and also make sure that the connector itself is not physically damaged.

If everything is in order with the power cable, you need to start diagnosing the outlet to which the computer is connected. Plug another electrical appliance into it and make sure it is in working order.

All modern power supplies have an on/off button on the case, which interrupts the power supply if necessary. It is important to ensure that the button is in the On position.

Important: Some power supplies also have a button with a switch for various electrical networks (most often 220 Volts and 127 Volts). Such a switch is not made in the form of a button, and to switch it to another mode you need to use tools. If your network has 220 Volts, and the switch is in the wrong mode, you also need to switch it.

Once the power source has been checked, you need to make sure that everything inside the computer is connected correctly. It is also important to check that, otherwise the power button will not be able to perform its assigned functions.

Note: In many modern cases, the power button has an indication that confirms that it is connected correctly and indicates by its glow that the computer is connected to the power supply, and there are no problems with this.

The computer turns on and then turns off immediately

There is a situation when, after pressing the power button, the computer starts to turn on, but before the sound notification about checking the hardware for errors (“squeaking” when turned on), it turns off. This problem occurs for the following reasons:

Please note that in some cases the computer may respond sound signal information about which of the elements there are problems with. For example, if the central processor quickly overheats, the system unit will begin to “squeak”, and if there are problems with the video card, it may emit several long beeps when you try to turn it on. Depending on the BIOS version, the information transmitted by the computer’s “squeaks” when turned on varies.

The computer turns on but the monitor does not work

If the system unit turns on (the coolers are spinning and the indicators indicate that it is working), but the image is not displayed on the monitor, you should first check the reliability of the cable connection from the screen to the system unit. You can also try switching the cable from a discrete video card to one integrated into the central processor.

from 150 rub.

Waking up in the morning, with the usual press of a button, you turn on your PC, and... nothing happens. You can panic, or start calling everyone you know who “seems to be a programmer or designer... But he should understand computers!”, or you can try to figure out what’s going on yourself. Possible reasons We will try to consider why the computer does not turn on and what to do about it in this article.

Important amendment: we will consider situations only when the computer does not turn on at all

1. After pressing the "Power" button nothing happens at all
2. the computer tries to boot (the lights turn on, the fan starts running), but immediately turns off
3. The lights work, a squeak is heard, but the computer does not boot.

The computer does not start - we are looking for the reason

The very first, and seemingly trivial step, is to check the network connection and cable operation. The advice may seem stupid to some, but in fact, at this stage, sometimes up to half of the situations are cut off. It is worth checking whether the cable has come loose and whether the socket is working.

These tips apply universally to other related devices: mice, printers, speakers, keyboards.

Checking the cable is simply pulling it out and plugging it into the socket. If the wire appears to be of poor quality and weak, of course it’s worth trying a new one just to check - at least for the cable from the monitor. And be sure to make sure that the button on the power supply (usually located near the power connector) is in the right position.

The main thing is not to confuse it with the input voltage switch button.

It is necessary to change the input voltage level between the American standard 127 V and our 220 V.

It is important that the outlet has 220 volt power - the functionality of the outlet can be easily checked by connecting other devices. If many consumers are connected to a single power source via tees, the load may be exceeded.

In such a situation, it is advisable to disconnect the remaining devices and check whether the PC turns on if it is the only one connected.

If the voltage exceeds or, conversely, does not reach the required norm, the machine may burn out or simply not turn on. There are special devices for testing voltage, but you can determine the level without them if you have an ordinary light bulb. If the voltage is insufficient, the lamp will shine dimly. If the voltage is too high, then the opposite situation occurs: the light bulb shines brightly, after which it may burn out.

If the computer beeps and does not turn on, we can try to determine the cause of the failure by the sound.

It is advisable to once again make sure that the speaker is connected to the motherboard correctly - perhaps the computer wants to give you a signal, but you are not aware.

Particularly relevant this problem for users who have never heard such squeaks from their own PC before.

Problems on each BIOS version may sound different. They may be higher or lower, longer or shorter, the combinations of signals may also not match. Let's look at some options.

For example, on one of the BIOS versions You can hear the following options:

• triple long/triple long – single short: problems with motherboard.
• Double short: PC doesn't see monitor.
• Short with repetitions / long without stopping: power supply failure, or motherboard malfunction.

In another BIOS version signaling can be as follows:

• Triple long: problems with the input device controller.
• Long-term without stopping: PSU malfunction.
• Single long - double short: video adapter not detected or disabled
• Long or short signals with constant repetitions: the RAM module is not detected or is disabled.

In the third BIOS version under review there is an important feature. Here the signals are built according to a system using several beep sequences. Older versions will have three sequences, and newer versions will have four.

• Long beep with constant repetitions: motherboard malfunction.
• Long non-stop: the fan is broken or turned off.
• Single - single - double: CPU malfunction, replacement required.
• Triple - triple - quadruple: video adapter memory is not initialized
• Triple - quadruple - single: the computer does not see the monitor, or records its error.
• Triple - Double - Quadruple: The input controller is not initialized.

Let's consider another BIOS version, the signals in which will sound as follows:

• Sevenfold short: motherboard failure detected
• Five-fold short: PC has detected a CPU malfunction
• Single long - four times short: the video adapter is not detected, or its error is noted.

In order to decipher what your computer is beeping about, you should know which manufacturer of your motherboard BIOS is from.

General list possible occurrence problems:

1. system voltage problems
2. Motherboard battery is dead
3. power button malfunction
4. connection or parts problems

If there is a fault in the power supply

Perhaps the most unpleasant problem that can befall your PC is if the power supply itself breaks down and does not work. It is not surprising that in this case the computer refuses to turn on. Moreover, such an event may lead to breakdown of other connected components.

You can check the existing power supply using a voltmeter, and for deeper diagnostics you will also need an ohmmeter.

But this method is only suitable for situations when the computer does not boot and the lights are on. To check, take the power connector and measure the voltage on it. This indicator between the red and black conductors should be 5 volts, between the black and yellow wires - 12 volts.

You can try to fix the problem by unplugging the power cord and leaving the computer without power for a while. Then return the cable and do a test run of the computer. There are situations when, after long use, wear and tear creates a “sticking” effect in the internal protection. If this does not help and you still cannot start the computer, move on to the next steps.

Yes, oddly enough, ordinary dust and dirt inside the computer can greatly affect its operation and be one of the reasons why the computer does not turn on. In order to test this hypothesis, you will need to clean the insides of the system unit (and the components would not hurt), but it won’t be superfluous anyway.

Cleaning should be done using a mini vacuum cleaner and a brush; it is advisable not to do this with cotton wool or paper disks so that fiber particles do not remain inside.

The suggested order is as follows:

• We clean the contacts of the RAM and boards.

To do this, the computer is disconnected from the network and the memory is removed. Many experts claim that contacts can be cleaned with a regular eraser; others use a cotton cloth the old fashioned way.
Attention: you should not wipe the entire RAM die, but only the contact track!

This is required in order to remove existing oxidation, which can interrupt the contact between the RAM and the motherboard. After this, you can use a brush or a brush with soft bristles so as not to damage the microscopic parts.

• We do the same with other cards, for example a video card.
• We check for contamination of the processor coolers.

We clean it and see if the fans are spinning. Due to contamination of the fans, the cooling system may not work well, in which case the computer will overheat and unexpectedly reboot without permission.

Dead battery

All motherboards have a small coin cell battery. It is often called a “BIOS battery” because it supports CMOS memory, which in turn stores PC configuration parameters (settings). BIOS Setup), as well as the system timer. Motherboards use lithium batteries that differ in capacity and thickness. On average, their service life is 2-5 years, so if a computer has been in use for that long, or even been in storage, the battery runs out. And along with it, the settings are lost.

Often PC owners discover this because Every time you turn it on, the time settings are lost(as we indicated above, the battery maintains a storage of system timer settings).

Sometimes battery problems are detected in other ways, through system messages, failure to launch some programs, even problems with working inside the browser. But to the point that the computer does not turn on, or turns on every other time.

The easiest way to check if the problem is with the battery is to buy a new one. They are not expensive, ranging from 50-100 rubles. If you can’t buy the right type of battery yet, but you have a voltage tester (voltmeter, multimeter) on hand, you can check the voltage. 2.7 - 3V is the normal voltage for CMOS BIOS operation.

If the voltage is less than two volts, the battery must be replaced with a new one. This means that the battery capacity has dropped, and in this case, the battery charging current also drops.

Power button problem

Surprisingly, sometimes the button itself may be the cause. If the contacts do not close well, then, of course, the computer does not turn on. On the motherboard we look for the place where the wires from the front panel of the case are connected, and there we look for the required connector (labeled “Power”).

There is probably no need to explain that situations when the computer does not boot occur quite often. There may be a myriad of reasons that led to this. Now we will try to figure out why such situations arise and how to deal with them. Let's consider exactly desktop computers, not laptops, although in some cases the methods for solving the problem may be very similar.

Causes of download problems

First of all, in the question of why the computer does not boot, you need to understand that among the main reasons there are two main ones: physical damage to components computer system and software failure (in this case Windows).

Both can cause serious problems. Let's look at the most common causes of failures and figure out how to eliminate the consequences.

Consequences of physical impact

As for damage to physical components, first you should pay attention to the initial stage of booting the PC. Probably everyone knows that when turned on, the system unit makes a characteristic sound (a single squeak). This indicates that all hardware components are in order. True, this is not always the case. The fact is that a hard drive failure is detected only after startup (the system does not see it).

Sometimes the system speaker may emit short and long squeaks. This is already worse. This can only mean one thing - some component is not working, has failed, or is simply incorrectly connected to the motherboard. For different versions BIOS signals may vary. But all of them may indicate malfunctions in the operation of RAM, video card, central processor, etc. In some cases, there may be no signal at all.

In this case, it is recommended to remove the system unit panel and check whether all components are connected to the motherboard. It may well be that the device does not work not because of failure, but because the corresponding cable is damaged. Naturally, it is not possible to determine such a malfunction yourself, so you will have to turn to specialists.

There are often cases when the computer does not boot even when turned on. There may also be enough reasons for this. It is very likely that there is simply no power supply. It is worth checking the outlet or uninterruptible power supply. Sometimes when turned on large quantity electrical appliances in the extension cord can trigger protection and much more. You can check the battery that is installed on the motherboard. It is very possible that after replacing it, turning on and booting the computer will go as usual. Often no one pays attention to this, nevertheless the fact remains a fact.

In general, you should immediately check all cables, sockets, extension cords, etc. Maybe this is really the reason. That’s why it turns out that nothing starts, nothing loads, the computer is black and shows no signs of life.

Crash systems

Of course, you can replace the hardware, but with the operating system itself the situation is much worse, because no one obviously wants to reinstall the system, hard formatting disk or partitions, which will result in data loss.

There are a lot of reasons for Windows crashing: a sudden power outage, incorrect shutdown or shutdown, a failure in software, the presence of viruses, damage to the hard drive, etc. The list can be endless.

Concerning physical damage hard drive, the severity of the problem can only be determined after full testing of the surface and contacts. If it burns out, you know, you’ll have to shell out money for a new one, there’s nothing you can do about it. If the damage is minor, you can try to restore bad sectors. This will be discussed a little later.

Basic methods to correct the situation

As is already clear, in terms of hardware failure, when the computer does not boot, the black screen hangs constantly, the system unit does not make a sound, the solution would be a complete test of all components. It is very possible that reconnecting or replacing some of them will clarify the problem.

It is worth noting that in some cases, when the system does not detect the hard drive, the most trivial situation may occur. In the BIOS, the boot priority can be set to, say, CD/DVD/ROM first, the second device is a USB drive, etc. It is clear that when media of this type is inserted, the system will display a message stating that this is not a system drive.

It also happens that the computer does not boot from the Windows installation disk. Here you will have to check the disk itself. It is very possible that there are some scratches or other damage on it. By the way, perhaps the drive itself is damaged and simply does not work.

Now a few words about how to correct the situation when the computer does not boot, Windows 7 does not start, and in general it seems that nothing can be done.

Let’s say right away: don’t despair and panic. Bill Gates is not a stupid person at all. When creating his system, he left loopholes to restore the functionality of the “operating systems”, and today there are quite a lot of methods that allow you to quickly and effectively apply measures that can, so to speak, breathe life into the system new life. Below we will describe the most common problems and methods for eliminating them specifically from the point of view of the Windows software shell.

Loading Last Known Good Configuration and Restoring the System

As a rule, even after very serious mistakes in Windows work 7, as they say, doesn’t just give up. On reboot (if everything is fine with boot records), testing occurs, and then in most cases a message is displayed about possible boot options, including loading the last known known configuration.

This happens because the system, as it were, remembers its last working state and offers to go to it, bypassing all the changes made before. In 90% of cases this helps. However, it also happens that the computer does not boot even if the Windows recovery, and the user ultimately receives a message that the configuration could not be loaded.

The same applies to using system restore, which may be offered when Windows starts. Sometimes it helps, sometimes it doesn't. In principle, both services are very similar. In this state of affairs, more effective measures will have to be taken.

Safe mode

Many users, faced with a problem, for example, when the computer does not boot after updating Windows 7, clearly underestimate the benefits of safe mode, but it allows you to gain access to a fully functional system and fix many software errors.

To load safe mode after the system starts, you need to press and hold the F8 key. When the system boots, we can take care of our problem. In this case, you can check all the hardware components for functionality and the presence of the appropriate drivers, run a disk check for errors, and finally begin restoring the system.

System Restore

First of all, using the control panel, you need to go to the “Backup and Restore” section. It can also be accessed from the main Start menu under All Programs/Maintenance. Here you need to select a checkpoint (the last one created or one of those present in the list) and start the process itself. This, of course, can take quite a lot of time, but if you don’t want to reinstall, you’ll have to be patient.

Now let's say that after the updates the computer does not boot. In the same control panel, if you go to “Center Windows updates"You can view the update log, in which, in fact, you will need to delete everything that was installed before the system crash, no matter whether these updates were installed automatically or manually.

In many cases, this approach allows you to revive Windows without resorting to more serious methods, which not every user can handle.

Using the Recovery Console

If the above method does not produce results, you will have to use other methods. One of the most effective and radical methods when the computer does not boot is to use the recovery console, which is available either on the Windows 7 installation or emergency recovery disk.

To use such disks, of course, you should make the appropriate boot priority settings in the BIOS, indicating the CD/DVD-ROM first in the list.

The boot menu will show a "Welcome To Setup" screen, after which you will need to press the "R" key to go directly to the console ( command line). It is worth considering that if more than one operating system is installed on the computer, folders with files will first be shown, and then a request will follow which system the user wants to work with. Now you just need to enter the number corresponding to the number of the selected system. You may then be prompted to enter the administrator password, provided that you have one. Now about the teams. What and how to enter and what to use, we will now figure it out.

Recovering the Boot.ini file

As a rule, one of the reasons for a system crash is damage boot file Boot.ini, which is responsible for booting the system. To restore it, almost all systems use a tool called Bootcfg. Bootcfg/Rebuild is entered on the command line (not counting other tools for scanning its entries, redirecting actions, adding identifiers, etc.). It seems that, apart from the main recovery command, the average user does not need anything else.

Recovering the Master Boot Record

The master boot record contains tables of all logical partitions of the hard drive. The so-called primary loader places the active and boot sectors in the tables, after which, in fact, the system starts. If the boot record is damaged, the active sector simply will not be able to start the system.

To restore in this case, use the Fixmbr command, after which you enter the qualified name of the disk or partition. In the case of drive C, the command will look like Fixmbr\Device\HardDisc0.

Recovering the boot sector of the hard drive

The boot sector is a small partition on the hard drive for storing data in file systems FAT32 or NTFS for boot. If it is damaged, use the Fixboot\c: recovery command (provided that the “OS” was installed on drive C).

Quick system reinstallation

Again, let's consider a situation where, after updating Windows 7, the computer does not boot, and the system simply does not want to start. As a last resort, you can use the so-called quick reinstallation of the system in the same folder where the previous OS was installed. In some cases, this may correct errors.

After the system starts from the disk, a window will appear license agreement. You can agree to the terms by pressing the F8 key, after which you will be asked to select an installation method. "R" key - recovery existing version, Esc - cancel recovery and go to new installation. In most cases, recovery proceeds without problems.

Virus check

Now a few words about another unpleasant situation, when the system does not start and the computer does not boot. A black screen may be the result of spontaneous viruses that either prevent the system from booting or change boot records.

In this case, it is recommended to use utilities such as Kaspersky Rescue Disc or Dr. Web Rescue Disc. As is already clear, such programs start directly from the optical disk, but, what is most interesting, they are loaded even before the Windows OS starts. They have GUI, so working with them is not particularly difficult. It should be noted that in 99.99% of cases, such applications remove even those viruses that are simply impossible to remove using standard scanners installed on the system. After all, they can “hang” even in RAM. At the end of the check, the computer terminal is rebooted, and, hurray, the system works again as if nothing had happened.

Conclusion

So we looked at the question of what to do if the computer does not boot. It seems that some solutions to this problem will be useful to many users. Of course, it’s quite difficult to say right away, right away, why a computer or operating system won’t boot. But if you conduct a comprehensive test and find out the cause of the problem, then you can choose the most appropriate method to correct the situation.

The first step is to establish the cause of the malfunction. If the situation is such that the computer turns on, but then itself operating system(OS) does not boot, 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, the problem is with system files, or their damage or complete loss. Try the tips below, all tips are for Windows XP:

1. 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.
2. Enter safe mode and try to restore the computer to its previous state. To do this, when you boot 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.
3. If previous methods didn’t help, then I suggest you look at 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. For this you will need 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 suit everyone.
   After booting from the CD, select " Windows installation XP" following the prompts. When a window appears notifying you that a previously installed OS has been found, press the R key. Thus, the program Windows installations 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 the jumper next to the battery and labeled Clear CMOS ( possible options 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. That is, we take out the video card, all RAM slots, disconnect from the power HDD and DVD-ROM, if there are additional devices (internal modem, sound card etc.) we take them out too, 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. Connect the most first important devices(video card, hard drive, RAM), and then 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.
