Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

There are cases when you want to undo some changes you’ve made to your computer and to do that you have to perform the System Restore task. However, if you encounter an error that states “To use System Restore you must specify which Windows installation to restore”, when doing so, read on as this post will help you fix the problem. This kind of error in System Restore could be due to corrupted files in the system. There are also situations where you are not able to boot up once you encounter this error which could be a big problem. On the other hand, this error might have something to do with corrupted BCD files. Whatever the cause is, here are some potential fixes you have to try.

Option 1 – Try to run System File Checker offline

Like pointed out, since the error might be due to corrupted system files, you can try to run System File Checker offline. How? Refer to these steps:

• You need to go to the Advanced Startup Options and from there select Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the commands given below and tap Enter right after you type each one of them.
  • Cd /
  • Dir

• If you can see the “Users” folder, that is your system’s drive. However, if you can’t see it, you can just change the drive-by assigning “D” as its alphabet volume.
• Then execute this command where “C” is the system drive: sfc /scannow /offbootdir=C: /offwindir=C:Windows
• Now repeat the given steps sequentially.

Option 2 – Try to run DISM tool

You can also run the DISM tool to repair the potentially corrupted system image. First, you have to check the health of the system like checking the integrity of the system files and Windows services. To run DISM, follow the given steps below sequentially.

• Open Command Prompt from the Advanced Startup options.
• After that, execute this command where “C:” is the system volume: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:C:WindowsWinSxS
• If you encounter an error after executing the given command, insert the Windows USB or DVD and then execute this next command where “E:” is the USB or DVD drive: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:esd:E:SourcesInstall.esd:1 /limitaccess
• In some cases, “install.esd” would be “install.wim” and in such case, you have to modify and execute this command: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:wim:E:SourcesInstall.wim /limitaccess

Option 3 – Try to repair corrupted BCD

As mentioned, the error could also be due to corruption in BCD, and to fix it, you can use Bootrec.exe – a built-in command-line tool used to troubleshot issues related to boot up and Windows Startup. Before you run this tool, make sure that you have inserted a bootable USB or DVD into your computer. Once you have that covered, follow these steps:

• You need to go to the Advanced Startup Options.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, enter each one of the following commands and in the sequence that they are given to rebuild BCD files and repair MBR files:
  • Bootrec /Fixmbr
  • Bootrec /FixBoot
• After you execute the commands given above, you should see a confirmation message that says, “The operation completed successfully”.
• Now type the “Bootrec /RebuildBCD” command to rebuild BCD.
• Finally, close Command Prompt and then restart your computer to successfully apply the changes made.

Option 4 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 5 – Try to use the Windows Recovery Environment

If the four options given above didn’t help fix the problem, you could try running Windows Repair and a Windows bootable USB or DVD.

• First, insert the bootable USB or DVD and boot into it, and select the “Repair your computer” option.
• Next, once you see the manufacturer logo on your computer, tap the key to enter into Windows Recovery Environment.
• After that, change the Boot sequence to DVD drive under the UEFI Firmware settings and restart your computer.
• Once your computer has restarted, select the boot order and make changes accordingly as displayed in the BIOS.

Option 6 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “exe /OFFLINE:C:Windows” and hit Enter to execute the command which will start the System Restore process.

Note: You need to replace “C” with the drive where Windows Installation is located.

OEM Partition, also known as System Reserved Partition, is placed by the OEM to help users recover their computers or bring back the original state of the computer when it was bought. If you’ve observed that a part of your hard drive says “Healthy (OEM partition)” in the Disk Management and it occupies space in GBs, then this means that it’s normal and there’s nothing to worry about except that part of the storage space is not available and even when you right-click on it, the only thing it displays is the Help menu. Thus, in this guide, you will be guided on how you can merge as well as delete an OEM partition in your Windows 10 computer. Since the Disk Management tool in Windows won’t let you merge or delete the OEM partition, you can just use the built-in command-line tool known as Diskpart. Note that you have to be extra careful when you run the commands as it could mess your computer up and before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once you have that covered, follow the instructions below. Step 1: Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and tap Enter to open the Command Prompt. Step 2: Next, execute this command to launch the Diskpart tool: diskpart Step 3: Execute this second command to view the list of the disks in your computer: list disk Step 4: Now select the disk you want to manage by executing this command: select disk x Note: In the command above, replace “x” with the letter of your disk. Step 5: After that, execute this command to display all the volumes or partitions: list partition Step 6: Now execute this command to select the partition you want to delete: select partition x Note: You have to replace “x” with the partition you want to delete. Step 7: Once done, execute this command to delete the selected partition: delete partition override Step 8: Afterwards, execute this command to merge the OEM partition with the adjoining value: Extend Note: if you only want to merge part of the partition, you need to use this command “extend [size=<size>]”. For instance, you want to extend its size by 5GB, then you need to type “Extend size=5000”. The size you set is the size you select from the OEM partition. This will extend the selected volume by size in MB or megabytes.

If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue. In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state. Step 1: Find out what’s keeping your computer from going to sleep. To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep. To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:

“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”

Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.

Powercfg -requestsoverride Driver "Legacy Kernel Caller" System

Step 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.

powercfg –devicequery wake_armed

After you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings

• Click on the Windows key and type “control panel” in the field and select the related search result.
• Next, select the Security and Maintenance option and click on the Power Options.
• After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
• Now click on the Change advanced power settings button and a new window will appear.
• Then look for the “Sleep” option and expand it. Make sure that the “Allow hybrid sleep” option is on.
• Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.

If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.

• First, go to the C:/Windows/System32/GroupPolicy/Machine location.
• And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
• Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
• After opening PowerShell, type this command: gpupdate /force
• The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.

• First, tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:

• Once you’ve executed the commands given above, restart your computer.

During Windows 10 installation, you will see all the beautiful user interfaces, however, what’s more, important are the drivers, your processor, and free storage disk in order for the installation to be successfully completed. So if you are getting the CompareExchange128 error during the installation of Windows 10, this means that the CPU lacks a very important instruction known as “CMPXCHG16B”. Thus, if you don’t have CMPXCHG16B, then it will result in the CompareExchange128 error when you install Windows 10. In fact, CMPXCHG16B, PrefetchW as well as LAHF/SAHF is a criterion for you to be able to use Windows 10 64-bit version when upgrading from an earlier version of Windows. So what exactly is the CMPXCHG16B instruction? The CMPXCHG16B instruction is the one that performs an atomic compare-and-exchange on 16-byte values. This instruction can also be referred to as “CompareExchange128”. The atomic compare-and-exchange means that the CPU compares the contents of a memory location with a given value. So if the values are the same, it modifies the contents of that memory location to a new given value. Note that this kind of issue only happens to the 64-bit Windows 10 version and the only way to resolve it is by getting an update on the hardware level from the OEM. On the other hand, if nothing really works, it’s maybe time for you to get a new CPU but before you resort to that, in the meantime, you can try following the options given below to fix the CompareExchange128 error during the installation of Windows 10.

Option 1 – Try to update the BIOS and Chipset Drivers

One of the best things you can do to fix the CompareExchange128 error is by updating the BIOS and chipset drivers which is why you need to check if your OEM has an update available for your computer’s BIOS as well as the related chipset drivers. But before that, you need to first check the BIOS version. To do so, follow these steps:

• Type “msinfo32” in the search bar and hit Enter to open the System Information Tools.
• After opening the System Information Tools, check the BIOS version.
• Then take note of that BIOS version. You also need to use the BIOS utility that came with your computer and use it for the upgrade. Note that it is different for every computer and if you don’t have it, you can just go to the OEM website and see if there is an option to download it there.

Option 2 – Try to downgrade to the 32-bit Windows 10 version

If option 1 didn’t work as the BIOS update is not available, you can also try downgrading to the 32-bit version of Windows 10. Keep in mind that this will bring restrictions on the amount of RAM installed and other places but that won’t be a problem as you can still switch.

Option 3 – Try buying a new hardware

If none of the first two options didn’t work for some reason then maybe it’s time for you to purchase new hardware especially if your computer is way too old. In such cases, it’s better to buy new hardware or better yet, a new computer that can keep up for the next couple of years.
