BIOS is the most important component of a computer, the activity of which is aimed at setting up the equipment, checking its operability, launching the operating system, and more. One of the most unpleasant situations a user may encounter is when the BIOS refuses to start.
Imagine a situation: suppose you decide to reinstall Windows on your computer, but in order to run the installer, you must enter the BIOS. You have made far more than one attempt to enter the BIOS, and all of them were unsuccessful.
Another situation: when the computer starts, the user first sees the BIOS interface, after which the computer proceeds to load the operating system. In some cases, the user may not see any image at all, that is, neither the BIOS window, nor anything else.
Reason 1: wrong key (combination)
First of all, you should doubt the correctness of the hotkey used, which you use to enter the BIOS. Unfortunately, to find out which key in your case can only be experienced, that is, it could not be entered into the BIOS using one button, the next time you should try another.
The process of entering the BIOS is as follows: you send the computer to reboot or just turn it on and at the very first stage of turning it on you start repeatedly and quickly press the hot key for the BIOS.
There are a huge number of options for entering the BIOS (this is especially true for laptops), but in most cases one of the following keys is found: F1, F2 and Del. If not a single key helped to enter the BIOS, try to “google” the model of your motherboard (for a stationary PC) or the laptop model on the Internet in order to find out how the BIOS is entered for your device.
Reason 2: a broken or unsupported keyboard
And although in rare cases the user has the opportunity to enter the BIOS without a keyboard, in 95% of cases you can not do without it.
Needless to say, the computer keyboard must be in good working order? Be sure to check the keyboard for functionality by logging into Windows, or by connecting it to another computer.
If the keyboard is working fine, then perhaps the problem is the BIOS unsupported keyboard. As a rule, a similar problem is observed among users of old computers (laptops), and if you use a wired or USB keyboard, then this probability may well be.
If you have a wireless keyboard, respectively, we will need to use a wired one to eliminate the possibility of a similar reason. Especially older versions of BIOS may not support USB keyboard interface, but to check this, you will need to either connect an old keyboard with a PS / 2 connector or purchase a PS / 2 adapter for a USB keyboard.
Reason 3: USB port inoperability
The port to which the keyboard is connected must be operational. Try connecting the keyboard to a different port and trying to enter the BIOS again.
Reason 4: conflicting devices
One of the computer's devices could fail, resulting in a conflict, which is why you cannot enter the BIOS.
Try disconnecting everything that is possible from the computer: drives, hard drives or solid state drives, all USB devices, PCI cards connected to the motherboard. If there is a built-in video card, then turn off the discrete one, and then try to enter the BIOS again. If the attempt is successful, connect one device to the computer to find out what is in conflict. Having identified the problem device, it will be necessary to deal with it (it is better to take it to a service center for diagnostics).
Reason 5: computer malfunction
If the BIOS starts making sounds when you turn on the computer, but doesn’t want to start at the same time, you should listen to the signals and fix them. Often, BIOS using these signals makes it clear what went wrong. On the Internet there are lots of tables that decode sound signals for different versions of BIOS, using which, you can quickly understand the cause of the problem and begin to eliminate it.
Reason 6: problematic BIOS settings
As a rule, a similar cause of the problem occurs when the user makes changes to the BIOS. In this case, you should try to reset the BIOS to factory settings. As a rule, in most cases, you will need to look under the body of the system unit, where on the motherboard you can find a special switch (CMOS jumper), which is set to position 1-2. To perform a reset, just turn the switch to position 3-4 for 15-30 seconds, after which you can return it to its previous position.
Reason 7: problems with the motherboard
The most sad cause of the problem is that the motherboard is almost the entire computer. If you suspect a malfunction in her work, you can carry out a small diagnostic procedure.
First of all, you need to inspect the motherboard itself: are there any oxidations, are the capacitors swollen? Any external changes indicate its malfunction, which means that all this must be eliminated. If oxidation takes place, it must be carefully erased with an eraser. If swollen capacitors - they should be re-soldered to new ones.
If everything is okay visually with the motherboard, you should try the following:
- Disconnect the computer from the network, and also remove all unnecessary devices: mouse, speakers, keyboard, any additional devices and cables. As a result, only the network cable and monitor should be connected to the system unit.
- Zero CMOS. To do this, you should remove the battery from the motherboard for a few seconds, and then install it back.
- Remove all boards from all slots on the motherboard, leaving only the processor and speaker connected.
- Start the computer and pay attention to the sound: if it is, it tells you that the motherboard is working. If not, then everything is much sadder - she does not respond.
If you have confirmed the hunch that the motherboard is working, you should try to take it to a service center - it is quite possible that a specialist will be able to return it to working condition.
These are the main reasons that affect the lack of a BIOS start. If you have comments on the article, leave them in the comments.
Oh guess the riddle: it stands as the hive is buzzing. But smoke does not come from the chimney, because this is not a native plant, but a computer on which the BIOS is damaged. And he buzzes because only now is he capable of. Without bios, he is just a bunch of lifeless iron. Is it worth it to worry about? Of course not. After all, now you have a great bedside table!
The system unit as a bedside table? Well, I do not! We know how to make it work. Today we’ll talk about how to restore the BIOS if it crashes.
Which leads to a BIOS firmware gathering
B IOS and its “descendant” UEFI, which are used to upgrade modern motherboards, are special computer programs necessary for the initial setup and management of PC devices until the operating system starts. They are stored in special flash memory chips on the motherboard, one of which is shown in the picture above. It seems to be a good storage place, reliable, but sometimes the BIOS’s become uncomfortable there and it escapes. More precisely, it is damaged and ceases to fulfill its tasks.
The causes of BIOS damage are not too many, in some cases they are obvious, in others - no. Here is a list of the most common:
- During a power outage on the computer.
- The flasher program (flasher) incorrectly interacts with the firmware or flash memory chip.
- A BIOS version that is not suitable for this motherboard is updated. Yes, .
- If the update is carried out from under a running operating system - a system crash or software interference, for example, anti-virus blocking.
- Incorrect user actions, for example, restarting the computer before the update is installed.
- Failure of flash memory chips.
- Hidden BIOS firmware errors. Sometimes this explains the spontaneous "gatherings" occurring for no apparent reason.
- Motherboard electrical problems.
How BIOS damage’s manifest
In most cases, the BIOS firmware is partially damaged, so the symptoms of a failure can be different:- When you press the power button, the PC turns on only the cooler, which immediately starts to rotate at maximum speed. Sometimes the LEDs on the body and keyboard light up.
- One or several seconds after switching on, a cyclic reboot begins. Outwardly, this is manifested by a cycle of spins and stops of the cooler, which are repeated while power is being supplied.
- When turned on, the power indicator lights up, the cooler does not spin.
- The computer shows no sign of life. This happens when the boot block, the boot loader of the BIOS, is damaged. This is the worst case.
There is no image on the screen. Even the manufacturer’s screensaver does not appear.
There are other forms of BIOS damage, more precisely, its area, which stores the configuration of the ME controller (part of the chipset) on the boards that work with Intel processors - the so-called ME-region. If there is a problem in this area, the computer or laptop may:
- Incorrectly load or not turn on at all.
- Turn off or restart at regular intervals.
- It is incorrect to adjust the speed of rotation of the cooler, for example, twist it at high speeds regardless of the load.
The elimination of such failures consists in reading the BIOS’s dump, replacing the ME region with a clean one and re-flashing it using the programmer. Since this is usually done by repairmen, rather than computer owners, we will not dwell on this. It’s better to do what you can do at home without special equipment and risk permanently sending your “iron pet” to the realm of eternity.
BIOS recovery without a programmer is possible only when saving the bootloader. It is sometimes possible to determine whether it has survived or not, by indirect signs: blinking the screen backlight, sound signals from the system speaker, the reaction of the motherboard to turn on without RAM (sound or flashing indicators), etc. If the BIOS bootloader is intact, the first moments of operation computers go fine, the crash appears a bit later.
How to restore the motherboard with flown BIOS’s
Asus
Many Asus desktop motherboards support technology USB Flashback, which is designed to quickly update and restore BIOS’s in the event of a failure. This does not require anything but a USB flash drive with a capacity of up to 4-16 GB and the BIOS file itself, which must be downloaded from the manufacturer’s website from the section about your “mother” model.After downloading the firmware you need to rename. For example, the file “Sabertooth X79” (model name) is renamed to “SABERX79.ROM”, the file “Sabertooth Z77” is renamed to “Z77ST.CAP”. Information on how the firmware file should be named for your model is most likely on the Asus website, but if you do not find it, check on the forums or in support.
Next, save the renamed BIOS on a USB flash drive formatted in FAT32, and connect it to the USB port marked “ Flashback" or " Rog connect". It is advisable to turn off the computer before this, this will increase the chance of a successful recovery.
After connecting the flash drive, turn on the PC and press the “ BIOS". Keep it pressed for about 3 seconds until the indicator light starts flashing on the board. A blinking indicates that the file was successfully read and flashed into memory. When the firmware process is completed, the indicator goes off.
If your board is from a budget segment or not too new, that is, it does not support USB Flashback, most likely you can restore it in another way. If your computer is equipped with a floppy drive or optical drive, write the renamed BIOS file to the root directory of a blank diskette or CD, put it in the drive, turn it off, and then turn on the PC again. The firmware will be completed when the drive indicator goes off. If there is no drive, use a USB flash drive.
Gigabyte
On Gigabyte boards with Dual (dual) bios, malfunctions rarely occur, since in case of firmware damage in the main chip ( Main_ BIOS) a dump from the backup ( Backup_ BIOS) While the main flash memory is operational and contains firmware, even damaged, the board remains operational.
Problems starting the board with Dual_BIOS are possible in the following cases:
- The main chip is missing or out of order.
- The microcode in the main chip is completely erased.
- Damaged contents of both chips.
Some Gigabyte mothers can boot from the backup flash memory and use it as the main one. Another group of boards from this manufacturer uses the allocated area on the hard disk as a backup BIOS medium. This is a less reliable option, but also better than nothing.
Restoring the Gigabyte BIOS from backup is usually performed automatically, but if this does not happen, try turning off the computer from the wall outlet, wait a bit, and turn it on again.
MSI and others
Most Micro-Star motherboards use firmware recovery technology, very similar to ASUS’s, using a flash drive, floppy disk, or CD. Copy the BIOS to a blank medium, connect it to a PC, press the power button for 4 seconds, hold down the combination on the keyboard leftCtrl +Home (or Alt +Ctrl +Home) and, without releasing the keys, turn on the computer. The start of the firmware process can be judged by the flashing of the flash drive or drive indicator.
BIOS on the MSI board. On the right is the JSPI1 port for firmware on the programmer On motherboards MSI and some other brands that are more than 8-10 years old, BIOS flashing is done from a floppy disk. The instructions for AWARD and AMI BIOS are slightly different.
To restore the AMI BIOS, do the following:
- Rename the BIOS file downloaded from the motherboard manufacturer's website to AMIBOOT.ROM.
- Transfer it to the root of a blank diskette. Insert the floppy disk into the drive of the turned off PC.
- Press left keyboard Ctrl + Home and turn on the computer.
To restore AWARD BIOS:
- Place the flasher and BIOS files on the floppy disk (usually downloaded in the same archive).
- Create a text document on the floppy disk, which indicates the name of the BIOS file with the extension bin. Rename the document to autoexec.bat.
- Further actions are similar to those given above.
By the way, some manufacturers of motherboards upload BIOS on their sites only in exe format - in “one bottle” with a flasher program for updating from under Windows. Sometimes such a file can be unpacked as an archive, but it is often not clear to users which of its contents is firmware. There is no universal solution for such tasks. In order not to aggravate the problem, it is better to consult in the relevant forums or in the technical support of the manufacturer.
On some boards, before restoring the BIOS, you also need to remove the real-time clock (RTC) battery from the socket or rearrange (remove) the CMOS cleaning jumper. It is important to find out these points before starting the procedure.
Features BIOS recovery on laptops
On laptops, as on Gigabyte boards, the BIOS is also often stored in two flash memory chips. But this is not Dual and it does not have backups. Both chips contain different parts of the firmware, or in one is the main BIOS, and in the other is the multicontroller program. So that the device does not turn on, it is enough to damage the microcode in at least one of them.
The recovery method for a flown BIOS’a on laptops is about the same as on desktops. The firmware file downloaded from the manufacturer’s website and the flasher program (the latter is not always necessary) are placed on a clean USB flash drive formatted in FAT32 / 16, connected to a de-energized device (just turning off the laptop is sometimes not enough, you need to disconnect the power supply and remove the battery), insert the charged the battery in place, turn on the device and hold down the key combination. On different laptops, various keyboard shortcuts are used for this, for example:
- Ctrl (left only or both) + Home
- Windows + B (this and other letters are in the Latin layout)
- Windows + F
- Windows + M
- Windows + Esc
- Fn + b
- Fn + f
- Fn + m
- Fn + Esc.
The main work is to unpack and rename the BIOS files. Here, again, there is no single rule. In most cases, it is necessary to get the firmware from exe-shnikov, but! Many manufacturers include BIOS’s for different revisions of one platform or a series of platforms in the program, and choosing from them the only file you need can be very difficult. In order not to be mistaken, read the instructions for the firmware of your model and platform revision on the relevant forums. And feel free to ask questions.
I intentionally do not provide in the article instructions for restoring BIOS’s by flashing on the programmer with or without flashing, shorting of various contacts, hot swapping of removable flash memory, etc., since all these methods are unsafe and require certain knowledge. However, among the readers, there are probably those who did something similar on their PC and got good results. It will be great if you describe your actions in detail in the comments to the article. Negative experiences are also welcomed so that other readers can avoid mistakes thanks to you. In the comments, be sure to include the model name and revision of your motherboard, as well as the BIOS version with which you worked.The BIOS is the Basic Input / Output System, the heart of the computer, without which the normal operation of other components and software is impossible. When you turn on the computer, the BIOS starts first and only after turning it on starts loading the operating system.
Theoretically, since Windows boots after BIOS, reinstalling the operating system or adding another OS should not affect the normal operation of the BIOS. However, it is not uncommon for an attempt to install a second operating system to cause the BIOS to fail to load.
In this case, we can assume that the BIOS settings were lost and restoring the default settings can solve the problem. To reset, you need to carry out the following operations.
- Disconnect the PC and monitor from the mains.
- Open the system unit and remove the battery from the motherboard.
- Wait a few minutes.
- Replace the system battery.
- Connect power to computer and monitor.
After restarting, the BIOS will start to boot “like the first time”. If after this the problem disappears, it is recommended to format the bootable hard disk and reinstall the operating system. Preferably the one that previously worked without problems. It is possible that the added operating system turned out to be damaged in the distribution.
Connection Disorders
It is very likely that the BIOS does not load due to interruptions in the power supply networks or data loops. To check this option, you first need to listen - does the cooler rotate on the motherboard. The BIOS is part of the processor and therefore poor cooling of the motherboard leads to malfunctions.
Perhaps the contact groups of the fan have gone, so it does not work. After that, carefully inspect all cable and loop connections. Check if dust has accumulated on the motherboard or in the contacts. Dust is an excellent conductor of electric current, and even creates electrostatic fields, to which electronics are very sensitive.
- Clean the machine from dust with a vacuum cleaner and brush.
- Separate the contactors sequentially and clean the terminals of dirt and oxidation. You can use school rubber to strip contacts.
- Check that all connectors are securely fastened. It is likely that the contacts parted from vibration, and therefore the equipment stopped working properly.
After prevention, you can try restarting the computer. Again, the screen is black and the BIOS does not load? Then we can assume that one of the internal modules is faulty. Including the motherboard itself could fail or it needs to be reflashed.
You can download a new flashing for the motherboard on the official website of the manufacturer. Updating the firmware is a difficult and rather risky task. Therefore, if you don’t know exactly what and how to do it, it’s better not to risk it, otherwise you can kill the whole computer in a place with hard drives. Contact a service center better.
Bad computer blocks
None of the above helped? Then the probability of malfunctioning iron increases and you can start checking the blocks.
Disconnect and remove from the device everything that is not necessary to start the computer. Leave only the motherboard, power supply and one of the RAM slots. The computer will not work in this condition, but it is possible to check the health of the motherboard itself.
A common reason for not being able to start a computer is the insufficient power supply. For example - you replaced the motherboard with a more advanced one, which requires more electricity. At the same time, the power supply remained old. Or so - additional hard drives or some other functional components were installed in the system unit. Energy consumption can grow quite strongly. Installing a more powerful power supply will solve the problem. If the question, of course, is the lack of energy.
Often, loading the BIOS is prevented by a malfunction in the video card. If possible, you must check the video card by replacing it with another similar one. Or install the video card in another computer. Here you need to look at hardware compatibility. Otherwise, you will not find the problem, but you can create new malfunctions.
If the minimum configuration - the motherboard, power supply, RAM socket - the system has worked and the BIOS is loaded, then the problem is in one of the removed modules. After installing and connecting the next unit, try turning on the computer again and see what happens. As soon as the BIOS stops restarting, you can assume that you have found a faulty block. Now it remains only to find a similar one and replace it.
In reality, it often turns out to be much more complicated. For example, a computer sometimes boots up and works quite normally, and then, for no apparent reason, starts to fail. The problem can be both violations in the software, and component malfunctions.
Such periods of normal operation, alternating with the inability to boot the BIOS, are characteristic of three types of problems.
- The presence of microcracks on the motherboard. Because of this, the contact periodically disappears.
- The electrolytic capacitors on the motherboard or in the power supply have dried. This malfunction mainly relates to old, long-in-use system units. Sometimes faulty capacitors can be detected by the characteristic bloating of the housing.
Poor contact in connected wires. As already mentioned - the presence of dust, oxidation of contacts, insufficiently strong clamp. If the contactors have fixing screws, they must be tightened to the end. There is a reverse situation - too tightly clamped screw-clamps lead to deformation of the connectors and the violation of the contact in the connection.
BIOS is the firmware responsible for bootstrap Windows. It checks the performance of components and add-ons. The correct loading of the computer and its normal operation (hardware components) depend on it.
It is recorded on the motherboard, and not on the hard drive, like the OS. In new devices, BIOS is replaced by UEFI, which performs the same functions, but is improved. Both programs sometimes need updating.
BIOS can be updated in several ways
DO I NEED TO UPDATE BIOS?
Manufacturers release a laptop update regularly. It is downloaded on the official website of the company that produced the laptop. It is more difficult for owners of PCs to own assembly. To find files for updating, they will have to build on the data from the motherboard chip. Any update is also written to the chip, replacing the old version.
Correctly updating bios is not difficult, but only materials designed for a particular model of PC or board should be used. Each motherboard has a strictly defined kind of firmware, and installing the wrong version of it can lead to disruption of the computer or its complete inoperability.
BIOS is a thin program, and therefore it is better to update it only in extreme cases. On a normally functioning PC, you do not need to update it. This is due to several factors:
- It is difficult to flash bios on an asus motherboard or any other, the process requires some skills, the process goes through DOS;
- Improvements will not be noticeable, since the differences between the versions are minimal and narrowly specialized;
- Possible malfunctions and malfunctions, as the old version was tested more thoroughly than the new one;
- During the work, the electricity should not be turned off, otherwise the device will stop loading.
But sometimes BIOS needs to be updated. If you regularly encounter one or another error in the work, go to the device manufacturer’s website and check if such an error has been fixed in the new firmware version. More often on the websites of manufacturers there is such a list. If this problem is really resolved in the new version, it makes sense to update bios on the laptop.
Another significant reason to flash BIOS is the installation of new equipment. If you purchased a new processor that appeared after the release of your motherboard, then it will not be supported by your BIOS. Manufacturers add support for new types of processors in the new firmware versions, and therefore you will have to download such a file and flash the firmware.
Update BIOS in a pinch. But even then, before upgrading, study the characteristics of the new version and find out if the problems are solved in it. Based on this, conclude whether to update bios.
Find out the current version by holding Win + R on the keyboard. In the window that opens, see msinfo32 for 32-bit operating systems. Click the Run button. A window opens listing the hardware and OS characteristics of the device. Among them, find the necessary.
Sometimes a notification appears that the mode is obsolete bios. This means that the BIOS operating mode is outdated, it still works in real, not protected mode. The firmware may not help to solve the problem, but it is not serious and it is not necessary to fix it.
UPDATE METHODS
The update method depends on the manufacturer of the computer, the model of the motherboard, etc. Most often, each manufacturer has its own flashing instructions. You can get acquainted with it on the official website of the company.
On all modern motherboards or you can update bios on your computer using any of the following methods. But it is better to choose the latter, since it guarantees a minimum number of errors.
UPDATE ALGORITHM
Update bios asus or any other modern laptop, you can use any of the three methods described. They have their own nuances, but when carrying out the process using utilities, they are still not complicated.
FROM DOS
A difficult option with great risks. To update bios on a windows 7 computer, do the following:
- Find out the model of your motherboard;
- On the manufacturer’s official website, download the necessary firmware version;
- There are sometimes several. In this case, choose the one that is intended for installation in DOS mode;
- Create a bootable USB flash drive with BIOS, DOS and an additional utility (it is downloaded on the manufacturer’s website or is included in the archive with the firmware);
- Install the USB flash drive and restart the computer;
- Specify the media on which the bios firmware of the motherboard;
- After flashing, restart the PC.
More precisely, there is no instruction, since it varies for different PCs and boards. Find detailed instructions on the manufacturer’s website. But using this method is not recommended.
FROM WINDOWS
Flashing bios on a laptop in this way is easy. Errors rarely occur. A popular method.
- Download the firmware utility. It is its own for every manufacturer. Program for updating bios asus - Asus Update, MSI - Live Update, etc .;
- Install the program;
- Run;
- Find the online search function for new firmware. In different programs, she is in different groups of teams;
- From the list of firmware select the necessary;
- Activate download;
- After downloading, run the flashing and follow the instructions of the program.
The firmware of bios asus, MSI, and others in this way is also safe because the program itself selects the appropriate firmware version. In addition, an intuitive interface will help to perform firmware even for an advanced user.
FROM BIOS
It is possible to reflash bios on the laptop from the firmware using the preinstalled utilities. This is a difficult method, as it differs depending on the model of the motherboard chip, manufacturer, etc. To update bios on the gigabyte motherboard, run the preinstalled @BIOS utility, other manufacturers will have different programs. Such programs are similar to the utilities used in the previous method, but are not so convenient. They also work with them - find the necessary file on the network and launch it.
More often, the method is used in case of computer breakdowns when it is impossible to enter the OS, because PC does not boot.
Many users do not know the answers to the question. They don’t know how to update BIOS. Do not think that updating this program is supernaturally difficult. Believe me, everyone can figure it out.
The abbreviation of this system in translation into Russian sounds like a basic input-output system.
Why do we need BIOS?
- During computer startup, BIOS checks for standard equipment and its viability. If any of this equipment burns out, a special beep will sound.
- The program launches a boot program that directly loads the Operating System.
- It provides the interaction of the OS with various peripheral equipment.
- Gives the user the ability to customize PC hardware components.
Do I need to update BIOS and why?
Updating this program is a deeper process than regular computer programs. This implies a short change algorithm. Basically, this is the correction of the malfunction of any rare components of the system or the addition of support for the latest processor models.
In that case, if the computer works without problems, it is better not to have business with this program. And it’s not worth updating it. You will not see the differences between the previous and the new version, and even vice versa, the update can generate unexpected problems for your PC. Most often, they arise when in the previous version more thoughtful testing was carried out than in the new one.
The update should only run for your motherboard model. If you try to update the BIOS designed for a different model, this can bring you a number of unpleasant difficulties and problems.
But there are times when updates are needed, and sometimes urgently:
- The motherboard requires the installation of a new processor, the provision of which is able to give an updated version. It is necessary to update the program in this case.
- You need to connect a hard drive of a size that is not supported by the old version of the program.
- It is required to activate additional functions of the chipset (a set of microcircuits that are designed for mutual operation in order to provide a set of various functions) that are not involved in the original version.
- It is necessary to replace the outdated OS on the computer.
- In the event that you plan to overclock your computer.
- The system functions slowly or incorrectly due to errors in the BIOS code.
- The version you have installed is broken, which is why the system does not work partially or fully.
What does the BIOS update give?
Updating the BIOS of the motherboard, as you already understood, is done mainly so that new processors and new memory that come out very often are supported by the motherboard installed on your computer. Because of this, updating the program is sometimes simply necessary.
Is it worth updating the program unnecessarily? Is it possible to update it constantly without thinking about the consequences? Programming professionals advise against this.
How to see the current current version of your system program?
- The fastest way to find out the current version is to use command line on your computer.
- Enter: Wmic bios get smbiosbiosversion. A window will open in which you will see the current version.
After you find out the information necessary for you, you should go to the website of the manufacturer of the motherboard, which is installed on your computer.
There are five most popular manufacturers:
How to update BIOS on a laptop?
Special programs for updating BIOS
Top 3 programs:
- Asus - Asus Update,
- MSI - Live Update,
- @BIOS.
General instructions for the programs:
Let's consider the option of updating BIOS from a flash drive:
How to make a boot disk for updating BIOS?
The method of updating from a floppy disk is considered one of the most reliable in terms of security.
After all these manipulations, you need to restart your computer and boot from a floppy disk. Make sure that the drive in the BIOS is installed as the first boot device. During the reboot, open the BIOS setup menu by pressing the special open keys. We select - Advanced BIOS Features, Boot Sequence, which are sometimes called Advanced, Advanced BIOS Features.
How to update BIOS without battery?
For updating purposes, often requires a charge of at least 10%. If this condition is not met, then the message "Power Check Error" will pop up before you, preventing the program from updating.
In order to still update it, you need to find out one key. What needs to be done for this?
Windows does not boot after updating BIOS
It happens that after the update, Windows stops loading. In this case, you need to start the BIOS of the computer. Find the parameters of SATA devices and try to change the operating mode. If the settings have an IDE, you need to activate AHCI (or vice versa). After that, save the new settings and restart the computer. 
And remember that you do not need to enter this system unnecessarily, as this can harm your computer! If you still do not understand some subtleties or cannot figure it out, contact a specialist!
Have a great day!
