When Should You Update BIOS and How Can You Update It Without USB?
BIOS, now commonly implemented as UEFI firmware, is the low-level firmware stored on a computer’s motherboard. It starts before Windows, initialises important hardware, checks devices such as the CPU, RAM, storage, and other controllers, and then passes control to the operating system.
Because BIOS firmware directly affects motherboard hardware initialisation, a BIOS update is not something that should be performed simply because a newer version exists. A working computer does not automatically need a BIOS update.
A firmware update becomes much more useful when the new version specifically addresses a hardware compatibility problem, stability issue, security vulnerability, processor support requirement, or another problem that applies to your system.
Should You Update BIOS If Your Computer Works Normally?
A Stable System Usually Does Not Need a BIOS Update.
If your desktop PC or laptop is running reliably, booting normally, recognising all hardware, and showing no important firmware-related problems, updating the BIOS is generally optional.
A newer BIOS version does not automatically mean better everyday performance. In many cases, the safest approach is to leave a stable firmware installation alone unless the manufacturer documents a meaningful reason to update it.
Before downloading anything, read the BIOS release notes for your exact motherboard or laptop model.
Look for information related to CPU compatibility, memory compatibility, system stability, security fixes, boot problems, hardware support, or other issues that match your situation.
When a BIOS Update Can Be Worthwhile.
A BIOS update can be appropriate in several situations.
One important example is a CPU upgrade. If you install a newer processor on an older motherboard, the existing BIOS may not contain the firmware support required to initialize that CPU correctly. In this situation, a BIOS update may be necessary before or after the processor replacement, depending on the motherboard and processor requirements.
Another common reason is persistent system instability. If you have already checked Windows, drivers, storage health, temperatures, RAM stability, and other common causes, a BIOS update may help when the motherboard manufacturer has released firmware specifically addressing the problem.
A firmware update can also be relevant when the manufacturer publishes a security-related fix. BIOS and UEFI security updates can address vulnerabilities in firmware components, processor initialisation, platform security features, or other low-level functions.
The important point is that the update should have a reason behind it.
Problems That Should Be Checked Before Updating BIOS.
A BIOS update should not be used as the first solution to every PC problem.
If Windows crashes, the computer becomes slow, or the system occasionally fails to boot, first determine whether the root cause is actually related to firmware.
Check Windows and Hardware Basics First.
Before updating BIOS, inspect the basics.
Check whether Windows is fully updated and whether the motherboard chipset drivers are current. Verify that the storage drive is healthy, RAM is stable, temperatures are normal, and recently installed hardware is compatible.
Also check whether the problem started after a driver update, Windows update, overclocking change, memory timing modification, or hardware replacement.
A BIOS update can sometimes solve a problem, but it can also introduce new firmware settings or compatibility changes. Good troubleshooting should identify a reasonable reason for the update.
Read the Manufacturer's BIOS Release Notes.
This is one of the most important steps.
The BIOS download page for the exact motherboard or laptop model normally includes version information and release notes. These notes can explain whether a firmware version adds CPU support, improves memory compatibility, fixes stability problems, or addresses security issues.
Do not choose a BIOS file simply because it is the newest file on the manufacturer's website. Confirm that it belongs to the exact hardware model and, when relevant, the exact revision.
How to Find Your Motherboard Model in Windows.
Before downloading BIOS firmware, you need the exact motherboard manufacturer and model.
Use Windows System Information.
Press the Windows key and search for System Information.
Open the application and locate the motherboard information, which can appear under entries such as:
BaseBoard Manufacturer
BaseBoard Product
BaseBoard Version
The manufacturer identifies the motherboard brand, while the BaseBoard Product usually provides the model name.
This method is useful because it does not require additional software.
Use CPU-Z for More Detailed Hardware Information.
CPU-Z is another practical way to identify motherboard information.
After installing and opening CPU-Z, select the Mainboard tab.
You can usually find the motherboard manufacturer, model, chipset information, and BIOS version in one place.
The BIOS section can also show the installed BIOS version and firmware date. This information is useful when comparing your current firmware with the latest version listed on the manufacturer's official support page.
Third-party identification tools should be treated as a convenience. The final BIOS download should always come from the official manufacturer support page for your exact model.
How to Find the Correct BIOS File.
Once you know the exact motherboard or laptop model, search for the official support page.
Use the Manufacturer's Official Support Page.
Search for the exact model followed by terms such as BIOS, Firmware, or Support.
For example, motherboard manufacturers may provide dedicated support pages containing BIOS downloads, drivers, manuals, and release notes.
Common motherboard brands include ASUS, Gigabyte, MSI, and ASRock, but the same principle applies to other manufacturers.
Never download motherboard firmware from an unknown mirror, random forum attachment, or unofficial file-sharing site when the manufacturer provides an official download.
Verify the Model and Hardware Revision.
Some motherboards have different hardware revisions with very similar model names.
Check the model printed on the motherboard, the product documentation, or the manufacturer's identification information.
A BIOS file intended for a different model or hardware revision can be incompatible and may cause a failed firmware update.
Download and Prepare the BIOS File.
After confirming the correct firmware version, download the BIOS package from the official manufacturer.
Extract the BIOS Package.
BIOS downloads are commonly distributed as ZIP archives.
After downloading the package, extract it to a normal folder in Windows.
Inside the extracted files, look for the actual BIOS image. The file extension varies between manufacturers and platforms. For example, one motherboard may use a file such as .CAP, while another manufacturer may use a different firmware file extension.
Do not assume that every motherboard uses the same BIOS file format.
Some manufacturers also include a BIOS renaming utility or an additional file that must be used before flashing. Follow the instructions supplied with your specific motherboard.
Can You Update BIOS Without a USB Drive?
USB-Free BIOS Updating Depends on the Motherboard.
This is a very important limitation.
Some motherboards provide firmware utilities that can access a BIOS file from an internal storage device or a supported filesystem. Others are designed around a USB-based firmware update process.
Therefore, BIOS can sometimes be updated without a USB drive, but it is not universally supported.
The internal-drive method shown in many demonstrations should only be used when the motherboard's own firmware utility can actually access the location containing the BIOS file.
Do not assume that creating a folder on the C: drive will work on every motherboard.
Prepare the Firmware on the Internal Drive.
If your motherboard's firmware utility supports reading BIOS files from an internal drive, you can place the extracted BIOS file in an easy-to-find location.
For example, you can create a folder near the root of the Windows system drive and copy the correct firmware file into it.
Keeping the file in a simple location can make it easier to find from the motherboard's firmware file browser.
However, the motherboard firmware environment may not display drives using the same letters used by Windows. A Windows C: drive may appear inside UEFI as a filesystem entry such as fs0, fs1, or another identifier.
The exact naming and navigation vary by motherboard.
How to Start the BIOS Flash Utility.
Restart the computer and enter UEFI/BIOS setup using the key specified by your manufacturer.
Depending on the system, the key may be Delete, F2, or another designated key.
Enter Advanced BIOS Mode.
Some motherboard interfaces open in a simplified or easy mode.
If necessary, switch to Advanced Mode.
The location of firmware tools differs significantly between manufacturers, so the exact menu path can change.
Common BIOS Flash Utility Names.
Manufacturers use different names for their firmware update tools.
ASUS commonly provides tools such as EZ Flash.
Gigabyte commonly uses Q-Flash.
MSI commonly provides M-FLASH.
ASRock commonly provides Instant Flash.
Other manufacturers may use different names, while some systems provide a BIOS update utility directly inside their UEFI interface.
The important part is not the name. Find the official firmware flashing utility designed for your exact motherboard.
How to Select the BIOS File Without USB.
Open the motherboard's BIOS update utility and look for available storage devices.
If the internal drive is supported, you may see filesystem entries rather than normal Windows drive letters.
Find the Correct Internal Storage Location.
Navigate through the available filesystem entries one at a time.
Locate the folder where you placed the BIOS file.
Open the folder and select the firmware image.
The motherboard utility should normally verify whether the file is compatible before flashing.
If the firmware utility reports that the file is invalid, unsupported, corrupted, or intended for another model, stop the process and verify the motherboard model and BIOS file.
Do not attempt to force an incompatible firmware file.
Protect BitLocker and Important Data Before Flashing.
BIOS updates can interact with TPM and platform security configuration.
If Windows uses BitLocker or device encryption, save the BitLocker recovery key before starting the firmware update.
The recovery key should be stored somewhere you can access even if Windows asks for it after the firmware change.
Why BitLocker Recovery Can Matter.
A BIOS or UEFI update can sometimes change firmware measurements or security-related configuration. Windows may then request the BitLocker recovery key during the next boot.
This does not necessarily mean that the BIOS update failed.
The important precaution is to make sure the recovery key is available before making firmware changes.
Depending on your Windows configuration and manufacturer's guidance, you may also be advised to temporarily suspend BitLocker protection before the update and resume it afterward.
Follow Microsoft's current BitLocker guidance and the motherboard manufacturer's instructions rather than disabling security features unnecessarily.
What Happens During a BIOS Update.
After selecting the correct firmware file, the motherboard may display the target BIOS version, model information, and other verification details.
Read the information carefully before confirming.
Once the update begins, do not interrupt the process.
Do Not Turn Off the Computer During Flashing.
This is one of the most important BIOS update rules.
Do not press the power button.
Do not disconnect the AC power.
Do not force a restart.
Do not close the laptop lid if the manufacturer warns against it.
Do not interrupt the flashing process simply because the screen becomes black.
The system may restart more than once, and the display can remain blank for a period of time while firmware is being written and hardware is reinitialised.
BIOS Updates Can Take Several Minutes.
The exact duration varies by motherboard and firmware.
During the update, you may see a progress indicator, a firmware update message, a reboot, or a temporary black screen.
Some systems also update additional firmware components during the same process.
The safest approach is to allow the motherboard to complete its own procedure unless the manufacturer specifically provides another recovery instruction.
What Is the fTPM Reset Message After a BIOS Update?
After updating the BIOS, some AMD-based systems may display a message regarding a newly detected firmware TPM or fTPM state.
This can happen because the firmware update changes the platform's TPM-related measurements or firmware environment.
Do Not Automatically Reset TPM Without Understanding the Warning.
A TPM reset can affect stored security information.
If Windows device encryption or BitLocker is enabled, the recovery key becomes especially important.
Read the exact message displayed by your system and follow the motherboard and Microsoft guidance for that configuration.
Never treat every TPM prompt as a generic confirmation that should always be accepted.
How to Confirm That the BIOS Update Worked.
Once Windows starts normally, you can verify the firmware version.
Check the BIOS Version Again.
Open CPU-Z and return to the Mainboard section.
You can compare the displayed BIOS version and firmware date with the version you installed.
You can also use Windows System Information and check the BIOS/UEFI version information reported by the operating system.
The important result is that the installed firmware should match the intended version for your motherboard.
What to Do If the BIOS Update Does Not Solve the Problem.
A BIOS update is not a universal repair for every computer issue.
If the original problem remains after updating, continue with normal troubleshooting.
Check RAM Stability.
Memory instability can cause boot failures, random crashes, application errors, and Windows instability.
Test the RAM properly and check whether aggressive memory profiles such as XMP or EXPO are contributing to the problem.
Check Storage Health.
A failing SSD or hard drive can look like a firmware problem because corrupted system files and read errors can cause boot failures and crashes.
Check the health of the storage device and investigate SMART warnings or manufacturer diagnostics when appropriate.
Check Drivers and Windows.
Update chipset, graphics, storage, network, and other relevant drivers from reliable sources.
If the issue started after a driver change, consider whether a rollback is more appropriate than another firmware modification.
Reset BIOS Settings Carefully.
A firmware update may reset settings to their defaults.
After the update, check important options such as boot order, virtualization, SATA or storage mode, memory profile settings, fan configuration, and other settings required by your system.
Do not change advanced options blindly.
Important BIOS Update Tips for Safer Results.
Before starting a BIOS update, make sure the computer has stable power.
For a desktop, avoid performing the update during an unstable power situation. A laptop should have sufficient battery charge and, where recommended, should remain connected to AC power.
Use only the BIOS file intended for the exact motherboard or laptop model.
Read the release notes before updating.
Keep your BitLocker recovery key available when encryption is enabled.
Back up important files before making major firmware changes.
Do not use BIOS firmware from unofficial sources.
Do not interrupt the flashing process.
Do not update BIOS simply because a newer date exists.
Most importantly, keep a record of your current BIOS settings if you have customised the system. A firmware update can restore default settings, which may affect boot configuration, virtualisation, memory profiles, and other options.
When a USB Drive Is Still the Better Choice.
Even when an internal-drive update is supported, a USB-based BIOS update can be simpler and more widely documented.
Some motherboard firmware utilities only recognize BIOS files from FAT32-formatted USB storage.
Certain boards also provide a dedicated BIOS Flashback function that is specifically designed to update firmware using a USB drive, sometimes even without a fully functioning CPU configuration.
Therefore, the correct method is always the one documented for the exact motherboard.
The goal should not be to avoid USB at any cost. The goal is to use the safest officially supported firmware update method available for your hardware.
Official Manufacturer Resources.
For firmware downloads and motherboard-specific instructions, use the official support page provided by the manufacturer of your device.
ASUS provides official motherboard support and BIOS download resources through its support website.
Gigabyte provides BIOS and motherboard support through its official support platform.
MSI provides motherboard BIOS downloads and firmware documentation through its official support website.
ASRock provides motherboard BIOS and Instant Flash documentation through its official support resources.
For Windows security features such as BitLocker, Microsoft Support should be treated as the authoritative source for current recovery and encryption guidance.
Note Point: Only update BIOS when there is a clear compatibility, stability, security, or hardware-related reason, and always follow the firmware instructions for your exact model.
Disclaimer: BIOS firmware updates involve a real risk of boot failure or hardware configuration problems if the wrong file or procedure is used; verify your exact model and follow the manufacturer's official instructions before proceeding.
