    How Do I Fix CMOS Date And Time Not Set?

    The CMOS checksum, or checksums, on your computer’s CMOS battery is what keeps your PC clock on even when the device is turned off. The battery is a 3-volt CR2032 button cell, usually found on scientific calculators, and is surprisingly inexpensive. A bad checksum could be the cause of the Date Time Not Set error on your computer, and there are several solutions to resolve this issue.

    In the first instance, you may need to replace the battery, which is usually located on your motherboard. The new battery should have no problem determining the correct date and time. However, if this does not work, you may need to charge the battery or replace the CMOS. Changing the battery should fix your issue. Once you’ve done this, you should be able to load your operating system again.

    If your PC still has an outdated BIOS, you can reset the CMOS date and time by rebooting the system. After you’ve done this, you’ll need to login with administrator privileges and use the advanced startup menu. If the advanced startup menu does not load, you should select the’restore default’ option. The advanced startup menu will attempt to fix any errors in the BIOS.

    What Happens If BIOS Time Wrong?

    The BIOS, or basic hardware system, controls the display of time on your computer. If the time is not displayed correctly, you may be experiencing a variety of problems, including a malfunctioning battery. Your motherboard’s CMOS battery may be the culprit, but you can repair it by going into the BIOS and pressing one of the following buttons: F1, F10, or Del. The BIOS repair key depends on your computer’s manufacturer.

    First, you need to check the BIOS settings. Some computers have issues with internal clocks. They drift from the correct time. This may be problematic for networks and Active Directory environments. Furthermore, a PC with a wrong time may have a problem using kerberos authentication. The most common fix for this issue is to update the BIOS. This may cause strange errors and serious problems if not handled properly.

    Lastly, you can manually change the BIOS time. Most motherboards have options to set wake-up times, but if this feature is disabled, you may experience issues using your local network or installing your OS. Sometimes, a BIOS time is wrong because of a virus or other infection. To fix it, you need to go into your BIOS settings and enter your credentials. If this does not work, try Googleing “What Happens If BIOS Time Wrong?,” then your computer should automatically reboot with a system-level clock.

    How Do I Sync My BIOS Time?

    You may have heard that a computer’s BIOS date and time is terribly inaccurate, but how do you fix it? It is crucial that you set the time correctly, as an inaccurate time can interfere with your internet browsing and network connectivity. Some motherboards even allow you to set wake-up times. Here are a few ways to fix the time and date. Follow these steps to keep your computer operating at its optimal time:

    If you’ve tried setting the time in the BIOS without success, you may need to go into the BIOS menu and change it manually. In Windows, you can access the BIOS settings by pressing Shift and a function key. The keys used vary depending on the manufacturer of your computer. The user manual will give you more details about the BIOS settings on your PC. Using this method will update the time on your PC’s BIOS, even if Windows is trying to synchronize the time with time servers.

    In case you have a bad CMOS battery, you might have problems setting the date and time on your PC. This problem can be resolved easily. First, you need to open the BIOS setup menu. Then, navigate to the Time and Date settings. Then, press F10 or Del to return to the previous screen. If you’re unable to use the mouse, use the arrow keys to navigate to the “System” menu.

    How Do I Reset My CMOS Clock?

    To know how to reset CMOS clock in bios, you should first learn what this is and what it does. CMOS, which stands for Complementary Metal-Oxide Semiconductor, is a chip that stores all the BIOS settings for your computer. This is one of the easiest, non-invasive methods of resetting your computer. Before you can reset CMOS clock, you must power off your computer and then press the appropriate BIOS key to restart the BIOS. If the CMOS battery is disconnected, you can remove it as well, but that will erase any saved settings in the CMOS memory.

    If you’re not able to find the jumper, then you can try another method. Most motherboards come with a 3-pin connector, which you can find by referring to the manual or by using a screwdriver. You’ll need a small screwdriver to connect the two jumpers. To clear the CMOS clock, locate the pins on the motherboard that are labeled JBAT1 and JBAT2.

    How Do I Fix CMOS Settings Wrong?

    If you suspect that the CMOS settings are wrong, there are a few steps you can take to resolve the problem. First, check your battery. If it’s charged, you can reconnect it. If not, you should replace it. If you haven’t done so yet, see your motherboard’s manual for more information. In some cases, the CMOS settings are wrong because the motherboard’s BIOS is outdated.

    Another common reason for CMOS checksum error messages is a conflict between the CMOS and BIOS. The CMOS isn’t able to load the old configurations correctly, which can result in this error message. This error message will usually go away if the CMOS battery is replaced. However, if it is not replaced, you can try rebooting the device using the default settings.

    You may also get the “CMOS checksum” error when your computer starts up. If it occurs after the PC has booted, it is an indication that the CMOS checksum is wrong. During the next boot, the system will restart and the error should go away. But if it doesn’t, this message will pop up every time you turn it on. To fix it, you need to restart the computer and reset the time and date.

    How Do You Reset the BIOS?

    If you’ve lost the BIOS date and time setting on your PC, you can reset it easily. You can find these instructions near the CMOS battery, or on the small plastic pin cover that covers the BIOS. Depending on the manufacturer, these instructions may vary slightly. If you’re unsure of how to reset your BIOS, HP provides support for many of their products. Once you’ve located the BIOS reset instructions, follow them carefully.

    Depending on your BIOS menu, look for an option labeled “Setup Defaults.” This option might be near the bottom of the screen or near the Save & Exit option. If you can’t find this option, click the “Factory Defaults” button and select the CMOS battery. If this doesn’t work, you can try replacing the CMOS battery.

    If you can’t access the BIOS menu, you can use your computer’s Clock app to reset your PC’s time. The Clock app lets you change the date and time. To hide the home time zone clock, simply turn off the automatic setting for your time zone. The Clock app lets you set the time in your home country without having to go through the BIOS. Alternatively, you can set the clock to show your local time, which is handy when traveling.

    What is Good BIOS Time?

    BIOS time refers to the amount of time it takes to boot the computer from the power on button to the display of Windows. The time is calculated based on the CMOS battery, which is installed inside the motherboard. An inaccurate BIOS time can cause problems with local networks and OS installation. Some motherboards let you program the time for a wake-up, which is another key feature to check. In either case, you need to make sure you know what is Good BIOS time before you start troubleshooting.

    The Last BIOS time is an indicator of how long it takes your PC to boot, but it is not an actual clock. This number represents the time that the BIOS or UEFI firmware took to load your system. It is the time between pressing the power button and Windows loading. Ideally, you want your Last BIOS time to be under 10 seconds. If your computer’s BIOS time is longer than this, try disabling post-check.

    Problem:

    You turn on your computer and get this error:

    Time of day clock stopped

    You can’t even get into the BIOS to set the time.  It just sits at this message forever.  My machine is an XPS M1330 but others have reported the same problem with other models.

    Solution:

    This article was helpful.

    1. Remove the battery.
    2. Remove the CMOS battery (coin battery inside the laptop).
    3. Remove the AC power adapter.
    4. Hold down the power button for 20 seconds to drain the system of all power.

    In my case, I continued holding down the power button while I inserted the AC power adapter and the system booted to diagnostics mode and began working again.  I then replaced the other batteries and the machine works again…for now.  Time will tell if this is a permanent fix.

The CMOS isn’t able to load the old configurations correctly, which can result in this error message. This error message will usually go away if the CMOS battery is replaced. However, if it is not replaced, you can try rebooting the device using the default settings.

    You may also get the “CMOS checksum” error when your computer starts up. If it occurs after the PC has booted, it is an indication that the CMOS checksum is wrong. During the next boot, the system will restart and the error should go away. But if it doesn’t, this message will pop up every time you turn it on. To fix it, you need to restart the computer and reset the time and date.

    How Do You Reset the BIOS?

    If you’ve lost the BIOS date and time setting bios time error your PC, you can reset it easily. You can find these instructions near the CMOS battery, or on the small plastic pin cover that covers the BIOS. Depending on the manufacturer, these instructions may vary slightly. If you’re unsure of how to reset your BIOS, HP provides support for many of their products. Once you’ve located the BIOS reset instructions, follow them carefully.

    Depending on your BIOS menu, look for an option labeled “Setup Defaults.” This option might be near the bottom of the screen or near the Save & Exit option. If you can’t find this option, click the “Factory Defaults” button and select the CMOS battery. If this doesn’t work, you can try replacing the CMOS battery.

    If you can’t access the BIOS menu, you can use your computer’s Clock app to reset your PC’s time. The Clock app lets you change the date and time. To hide the home time zone clock, simply turn off the automatic setting for your time zone. The Clock app lets you set the time in your home country without having to go through the BIOS. Alternatively, you can set the clock to show your local time, which is handy when traveling.

    What is Good BIOS Time?

    BIOS time refers to the amount of time it takes to boot the computer from the power on button to the display of Windows. The time is calculated based on the CMOS battery, which is installed inside the motherboard. An inaccurate BIOS time can cause problems with local networks and OS installation. Some motherboards let you program the time for a wake-up, which is another key feature to check. In either case, you need to make sure you know what is Good BIOS time before you start troubleshooting.

    The Last BIOS time is an indicator of how long it takes your PC to boot, but it is not an actual clock. This number represents the time that the BIOS or UEFI firmware took to load your bios time error. It is the time between pressing the power button and Windows loading. Ideally, you want your Last BIOS time to be under 10 seconds. If your computer’s BIOS time is longer than this, try disabling post-check.

    Computer time and date get reset or losing time

    Updated: 06/30/2020 by Computer Hope

    A computer losing time or having the date and time reset is a symptom of an issue relating to the computer hardware or software. There are multiple causes for date and time loss or resetting issues. The most common causes are detailed below. Review each possible reason for help with how to fix the problem.

    Computer CMOS battery failing or bad

    CMOS batteryIf the date reset to the BIOS manufacturer date, bios time error, epoch, or a default date (1970, 1980, or 1990), bios time error, the CMOS battery is failing or is already bad.

    Before replacing the battery, set the date and time to the correct values in CMOS setup and save and exit the setup. If the values are lost again, set the values again, but leave your computer on for 2-3 days without turning it off. In some cases, bios time error, this helps enable the CMOS battery to retain its settings for longer.

    If this does not resolve your issue, replace your CMOS battery.

    Note

    Older bios time error may not have a BIOS that is compatible with any year 2000 dates. If your computer was manufactured before 1995, we recommend you contact the manufacturer to determine if the motherboard's BIOS is Y2K compatible.

    Issue with APM

    APM, or Advanced Power Management, can cause issues with the computer keeping time. Verify this is not the issue by entering CMOS setup and disabling APM or Power Management.

    If this does resolve your issue, consult with the motherboard manufacturer or computer manufacturer for a possible BIOS update.

    Third-party utility or program

    Third-party programs or screen savers can cause the time to stop or decrease significantly. If you are running Windows, bios time error, close and disable all screen savers, and End Task all TSRs to ensure your lost time is not being caused by these programs.

    If this resolves your issue, bios time error, reboot the computer and determine what TSR or screen saver was causing this issue by disabling one TSR at a time. You can also leave the bios time error saver disabled to eliminate that as causing the problem. Once the culprit is found, see if the program has any available updates to resolve your issue.

    Virus infection

    Some computer viruses can infect a computer and cause the date and time in the operating system to be incorrect or reset to a wrong time zone. A virus can conflict with operating system files that manage the date and time or cause operating system files to become corrupted.

    We recommend you run a virus scan to see if your computer is infected. If any viruses are found, remove the viruses from your computer to eliminate the infection. Change the date, time, and time zone back to the correct settings, then restart the computer.

    If the date and time are incorrect again after restarting the computer, there may be corrupt operating system files causing the issue. Determine when the problem started to occur, then restore the operating system to a previous date before the problem occurred the first time.

    Corrupt operating system files

    It is possible for operating system files to become corrupted, causing the date and time to be incorrect. Corrupt files can occur due to a virus infection, as mentioned above, or for other reasons. The best bios time error to fix corrupt operating system files is to restore the operating system to a previous date before the problem occurred the first time. The restore process replaces the corrupt files with good files and hopefully fix the date and time issue.

    Windows 95, Windows 98, or Windows ME user

    When changing the year in Windows 9x or Windows ME, the time stops until the Apply button is pressed.

    When changing the month or date in Windows 9x or Windows ME, the time may decrease by 5-10 seconds.

    Answer
    motherboard battery died i would think. then at some point you lost power so the bios clock reset. reboot the computer into your bios (delete seems to be a popular key for that these days, but it can be f2 or f12 or f10. it depends on your board) and change the bios clock settings directshow error opening file/stream bet the date is off also)  then shut it off, pull the plug, count to 15 and repeat. if the bios clock is wrong again then your battery is dead. if it's correct you have a different problem.

    CMOS Checksum Bad – Date Time Not Set

    cmos checksum bad - date time not set error

    When you boot your PC and get a CMOS Checksum Bad – Bios time error Time Not Set error, do not panic. It simply means that the CMOS battery on your motherboard is failing or is drained. The good news is that fixing this problem is quite easy – just replace the CMOS battery.

    CMOS Checksum Bad – Date Time Not Set error is a common problem that can occur on any computer. If you are seeing this error, don’t worry – we can help! In this guide, we will walk you through the steps to fix CMOS Checksum Bios time error – Date Time Not Set error. We will also discuss bios time error of the causes of this error and how to prevent it from happening in the future. Let’s get started!

    What is CMOS

    CMOS is short for Complementary Metal-Oxide-Semiconductor and it keeps your PC’s clock running while it is turned off so it can remember your current settings when you turn it on again. A typical CMOS battery is a 3-volt CR2032 button battery that is mostly used on scientific calculators. It can last for years (5 years or longer) and is fairly cheap.

    Common causes of CMOS Checksum Bad – Date Time Not Set error

    The CMOS Checksum Bad – Date Time Not Set error can be caused by a variety bios time error things, including:

    – A bad CMOS battery

    – Incorrect CMOS settings

    – A faulty motherboard

    Fortunately, there are a few things you mysql error 2006 do to fix CMOS Checksum Bad – Date Time Not Set error. We will go over each of these methods in the bios time error below.

    Methods to fix CMOS Checksum Bad – Date Time Not Set error

    One way to fix CMOS Checksum Bad – Date Time Not Set error is to replace the CMOS battery. The CMOS battery is stop c00002la unknown hard error for keeping the CMOS settings stored in memory, and if it fails, the settings may become corrupt. You can usually find the CMOS battery on the motherboard, and it is usually a small, round, silver-colored battery. Once you have found the CMOS battery, simply remove it and replace it with a new one.

    Another way to fix CMOS Checksum Bad – Date Time Not Set error is to reset the CMOS settings. You can do this by removing the CMOS battery for a few minutes and then replacing it. This will cause the CMOS settings to be reset to their default values. Once the CMOS settings have been reset, you can then enter your new settings and save them.

    When you get the CMOS Checksum Bad – Date Time Not Set error, you will get two choices – you can run SETUP (BIOS) and bios time error the correct date and time there, or you can continue to boot with default values and set the right date and time there.

    Theoretically, your PC will still to power-on if you do not replace this battery but you will continue to get this error. That means you will have to go through those extra steps on BIOS every time you system error 1396 has occurred off your machine and then boot up which can be annoying.

    It is recommended to set the correct date and time in BIOS than to do it after you enter your system though. The bat error 551 if any of your software is set to auto-update, bios time error, it can look ugly when you do not correct your system date and time quickly enough. Imagine your anti-virus saying that it is out-of-date because you last updated in 1990 – and the only way you can get rid of that is to wait until your anti-virus sends out another update while your PC system date and time are current.

    The good news is that replacing the CMOS bios time error is quite simple. Make sure all power is off on your machine and unplug all cables on your CPU case (make sure you remember where all of them go for when you plug them back in). Open the case and you will see the battery on the motherboard, bios time error. Carefully take it out and replace it with a new one. Now, it is just a matter of putting the cover and cables back.

    But if you could not be bothered with replacing the CMOS battery or want to hold it off for a little while, it may still boot normally without the CMOS error if you keep your machine plugged in your wall outlet (or if it is on a power-strip and you keep the power-strip turned on). In a way, that keeps the CMOS clock running even if the PC is bios time error again, if you will be out for weeks or months, it is not practical to keep your PC plugged in for that duration. It is best to replace the CMOS battery as soon as you get the chance. If you do, you can forget about it for maybe another 5-10 years again which by then, you may want to upgrade your machine anyway.

    Replacing the CMOS battery is a whole lot better than worrying about keeping your PC plugged in or having to reset the date and time on BIOS every single time you get the CMOS Checksum Bad – Date Time Not Set error. Besides, a CR2032 battery lasts a really long time so you will probably only have to replace it once and not think about it again.

    If neither of these methods work, you may need to replace your motherboard. A faulty motherboard can cause a variety of problems, including CMOS Checksum Bad – Date Time Not Set error. If you think your motherboard may be the problem, we recommend taking it to a qualified technician for further diagnosis.

    Preventive measures for CMOS Checksum Bad – Date Time Not Set Error

    Now that we’ve gone over how to fix CMOS Checksum Bios time error – Date Time Not Set error, let’s talk about how to prevent it from happening in the first place. One of the best ways to do this is to keep your CMOS settings backed up. That way, if something does bios time error wrong, you can simply restore your CMOS settings from a backup and avoid having to troubleshoot the problem.

    Another way to prevent CMOS Checksum Bad – Date Time Not Set error is to regularly check your CMOS battery. As we mentioned earlier, the CMOS battery is responsible for keeping the CMOS settings stored in memory, and if it fails, the settings may become corrupt. To avoid this, we recommend checking the CMOS battery every few months to make sure it is still working properly.

    We hope this guide has been helpful in troubleshooting CMOS Checksum Bad – Date Time Not Set error. If you have any further questions, please feel free to reach out to us in bios time error comments section below. Thanks for reading!

    When you turn your Toshiba computer on, you see an error message like: **** Bad RTC battery **** **** Bad Checksum (CMOS) **** Check system, then press [F1] key The Real Time Clock (RTC) battery provides power for the internal clock/calendar and for maintaining system configuration settings.

    This error can occur when a machine has been left turned-off for an extended period of time (approximately one to four months), and it is the result of a depleted RTC battery. Other symptoms include not being able to execute Windows Update properly, errors/problems executing application software (like Norton Antivirus), and the appearance of the Windows XP "Desktop Clean Wizard".


    1. Set BIOS defaults
      1. Press the [F1] key as instructed in the error message: **** Bad RTC battery **** **** Bad Checksum (CMOS) **** Check system, bios time error, then press [F1] key
      2. In the BIOS setup screen press the [Home] key to restore the default values, then press the [End] key to save and exit, then the [Y] key to confirm and restart the system.
    2. Set the correct date and time in Windows
      As Windows starts-up, you may see an error message about an "Invalid System Time", bios time error. Samsung scx4300 error cpsfunc ahead and click "OK" to clear the error dialog.

      Open the Windows Control Panel and open the "Date and Time" control by double-clicking its icon. Set the correct date and time, then click OK to save.

    3. Charge the Real Time Clock (RTC) battery
      To charge the RTC battery, connect the AC adapter and turn the computer on (both the DC IN and Power LEDs must be green). Leave the machine on for approximately 24 hours to ensure a full charge in the RTC battery. Please note that the RTC battery does not charge while the PC is turned off, regardless of whether the AC adapter is connected or not. bios time error

    Other Information:
    If, on subsequent reboots, the error persists, it's quite likely that you actually do have a bad RTC battery. If that's the case, you should contact a Toshiba Authorized Service Provider to have the system serviced.

    Windows XP Desktop Cleanup Wizard
    The first time you reboot Windows XP after resetting the system clock, Windows XP may try to run the "Desktop Cleanup Wizard". Simply Cancel the "Desktop Cleanup Wizard" at the first dialog.

    If you do manage to clean your shortcuts from the desktop and want to recover them, you will find them in a folder called "Unused Desktop Shortcuts". You can recover them as follows:

    1. Double-click to open the "Unused Desktop Shortcuts" folder
    2. Click to expand the "Edit" menu, and click "Select All"
    3. Drag the selected items back to your desktop
    4. Close the "Unused Desktop Shortcuts" folder. You can delete this folder if it is empty.

    Note:

    If, on subsequent reboots, the "Bad RTC Battery" error persists, it's quite likely that you actually do have a bad RTC battery. If that's the case, you should contact a Toshiba Authorized Service Provider to have the system serviced (the battery is not user replaceable).

    Is Your Windows 10 or 11 Time Wrong? Here's How to Fix the Windows Clock

    If the time on your Windows 10 or Windows 11 computer is always wrong or keeps changing, the cause could be anything from a dying battery to a faulty setting. We'll show you why your computer clock is off and how you can make it right again.

    Let's walk through the most common reasons why your computer clock is wrong, whether it's off by a few minutes or keeps resetting.

    1. A Dead CMOS Battery

    This is a likely culprit of PC clock issues, especially if your computer is fairly old.

    The CMOS battery sits on your computer's motherboard and provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip. This chip stores information about the system configuration, including the date and time. The CMOS battery makes sure the chip can store this data, even while your computer is turned off and not hooked up to power.

    If this battery goes bad, the chip starts losing information. One of the symptoms is that your Windows computer no longer maintains its time and date properly. Every time you restart your PC, you'll find bios time error the clock defaults to an inaccurate date and time, such as January 1 at midnight.

    Thankfully, replacing the CMOS battery is pretty easy. You just have to turn off your computer, ground yourself to protect against static electricity, open the case, and check which type of battery is in your motherboard. Then after you buy a replacement (they're cheap), open up your PC again and replace the CMOS battery.

    See our bios time error to CMOS motherboard batteries for more information. It's easy to swap them on desktop computers, but might be more difficult with a laptop, depending on your model.

    2. An Incorrect Time Zone Setting

    When your computer clock is off by exactly one or more hours, Windows may simply be set to the wrong time zone. Even if you fix the time manually, Windows can reset itself to the wrong time zone once you reboot. If the minutes are correct but the hour is wrong, a misconfigured time zone is probably the issue you're dealing with.

    To fix your time zone in Windows 10, right-click the system clock in your System Tray at the bottom-right corner of the screen and select Adjust date/time. You can also go to Settings > Time & Language > Date & time. On Windows 11, these options look slightly different lg error code red green green green are accessible in the same way.

    In the Time zone box, check whether the information is correct. If not, select the correct time zone from the dropdown menu. You may need to disable the Set time zone automatically slider if the dropdown box is grayed out.

    For convenience, you should enable both Adjust for daylight saving time automatically and Set time automatically so you don't have to worry about updating them manually. Finally, while here, you can click Sync now to make sure Windows pulls the correct time from the time server.

    3. Windows Time Is Out of Sync

    If your CMOS battery is still good and your computer clock is only off by seconds bios time error minutes over long periods of time, bios time error, then you could be dealing with poor time synchronization settings. You should first confirm that your computer is syncing its clock with a valid time server.

    To do this on Windows 10, head to Settings > Time & Language > Region, then choose Additional date, time & regional settings from the right side. This will take you to the older Control Panel interface. Under the Date and Time tab, bios time error, click Set the time and date, which opens another window.

    On Windows 11, select Additional clocks on the same Date & time Settings page mentioned above to get to this menu.

    Once you're there on either version of Windows, switch to the Internet Time tab, click Change Settings, and you can change the Server if needed.

    Pick an option from the dropdown menu or enter a server of your choosing. Your system will use this to bios time error the clock to keep it from drifting slowly over time; choose Update now to force a sync. Make sure you have Synchronize with an Internet time server checked.

    Now, to make sure Windows is actually synchronizing partition magic error 117 time regularly, press the Windows key to open the Start menu search, type services, and open that utility.

    In the Services window, find Windows Time in the Name column, right-click it, and select Properties.

    In the Windows Time Properties window, set Startup type to Automatic, bios time error. Then click Start to make sure the service is running, followed by OK to save your changes. This should force Windows to regularly check in with the time server so your PC's clock is accurate.

    4. Adjust the Clock in Your BIOS/UEFI

    In most cases, an incorrect PC clock is an issue with Windows. But if nothing above has fixed your problem, there's a chance that the clock on your motherboard's BIOS or Bios time error is wrong, which can confuse the OS. Since this is the system time on your motherboard, it's deeper than the clock your OS uses.

    The exact location of this option can differ depending on your machine, so there's no one place to locate the system time. See how to enter the UEFI or BIOS on your computer; once inside, bios time error, look for a Time or Clock entry, where you can check for an inaccurate time and fix it if needed. If you can't find it, check your motherboard's manual or Google the name of your computer plus "BIOS clock setting" to find the right location.

    Once this system-level clock is correct, run through the above steps in Windows again and they should stick.

    5, bios time error. An Incorrect Computer Clock Could Be Malware

    While unlikely, this is the least pleasant scenario because malware is often difficult to remove.

    If nothing above worked to fix your PC's clock, perhaps malware hijacked your computer and is messing with its time. To fix it, you need to gather a few malware removal tools. First, make sure your antivirus program is up to date with the latest virus definitions. Then, get a good on-demand secondary malware scanner, like Malwarebytes.

    Once you have all these tools downloaded, updated, and installed, boot bios time error Safe Mode and run bios time error. It's important to start in Bios time error Mode, bios time error, because the malware won't launch at startup and be active when you choose this boot mode. This means it's less likely to escape detection and removal.

    If you're running Windows 10 or 11 and some basic scans don't fix the issue, it's a good idea to reset or refresh your system so you're sure to eliminate the malware.

    To protect yourself from future infections, keep both your system and installed software up-to-date, and follow basic advice to avoid picking up viruses.

    Your Windows Computer Clock Is Back on Time

    Having the wrong computer time can seem like a minor issue, but since a lot relies on the clock, strange errors can occur when it's wrong. After this fix, you'll know to pay attention to the small details of your computer. Simple oddities can be a sign of serious trouble ahead.

    For example, if your CMOS battery dies, your computer will forget everything when it reboots, so it has to recognize its hardware components every time it boots. That's just as annoying as a virus playing tricks on you, bios time error, or a bad time zone setting that messes up everything from the clock to your email client's timestamps. Be vigilant and act immediately when you see something out of place.

    If you're really into your PC's clock, why not customize it to improve its look?
