Chkdsk Error - How to fix It In Seconds

If you are a gamer, you might have encountered either the CID HANDLE CREATION or VIDEO TDR ERROR errors with an error code of 0x00000016 as you play a game. These kinds of Stop errors have something to do with the Graphics card driver. It could be that your Graphics card driver needs to be updated or it may be corrupted. Whichever the case is, you can try fixing this error using the given solutions below but before you proceed, make sure to create a System Restore Point first so that you can easily roll back to the previous state of your computer in case something does not go as expected.

Option 1 – Try checking if your graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the graphics card is enabled or not. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• After opening the Device Manager, look for your graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.
• Next, right-click on the graphics card once more and click on the Update Driver Software option and then click on the “Search automatically for updated driver software” option.

Option 2 – Reinstall the Graphics card drivers

• Tap Win + R to open Run then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the Display adapters and uninstall each one of the graphics card drivers by right-clicking on them and selecting the Uninstall device option.
• After uninstalling the graphics card drivers, close the Device Manager and tap Win + R to open Run once again.
• After that, type “appwiz.cpl” in the field and hit Enter to open Programs & Features in the Control Panel.
• Next, look for any program that’s related to your GPU manufacturers like Nvidia, AMD, or Intel. Right-click on any GPU-related entry and click on Uninstall to uninstall them and then follow the next on-screen instructions that appear afterward.
• Now restart your computer.
• Once your computer has restarted, go to the GPU manufacturer’s website and download the latest driver version for your graphics card model and then install it.
• Restart your computer once again. That should fix the problem.

Option 3 – Try reinstalling the game

If updating and reinstalling your Graphics card driver didn’t help, then you can try to reinstall the game where you’re getting the CID HANDLE CREATION or VIDEO TDR ERRORS.

Option 4 – Uninstall the programs you installed recently

Chances are, some programs that you just installed might be the one that’s causing the BSOD error. Thus, you need to uninstall the program to resolve the problem.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it. In addition, you might also want to check the hardware components of your computer that might not support the operating system itself. You can disconnect all the external devices like USB drives, scanners, printers, etc., and then reboot your PC. After that, add the devices again one after the other and check if the BSOD error is now fixed or not.

Option 5 – Try disabling your monitor’s Sleep functionality

There are times when the Sleep functionality of your monitor can also cause BSOD errors like CID HANDLE CREATION or VIDEO TDR errors. There are also times when the graphics card is running in the background and the display goes to sleep and then it’s turned back on but you encounter this kind of Blue Screen error. This is why you can try to disable your computer monitor’s Sleep mode.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like CID HANDLE CREATION or VIDEO TDR errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 7 – Try to run the Chkdsk utility

Running the CHKDSK utility might also help you resolve the CID HANDLE CREATION or VIDEO TDR errors. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

In trying to upgrade your Windows 10 computer, you might have come across the error 0x800F0923.

Microsoft's anniversary update has come with many new features and improvements. One of these features is that Microsoft's Cortana can now be installed on your Android phone and as long as you are logged in to your Microsoft account on different devices, she can pass information between devices. You can not see battery life on your desktop PC, notifications, etc. There are some prerequisites in order to get this going, first is to have a Windows version 1607 or newer. The second is to have the last Android version

Installing Cortana on Android

1. Download and install the Cortana app from the Google Play store.
2. Open the app and accept the license terms.
3. Enter the credentials for the Microsoft account you use to sign in to your PC.
4. After a few seconds, Cortana will open.
5. Click the settings button and select Sync Notifications.
6. By default, missed calls, incoming messages, and low battery notifications will be turned on. You can turn this on\off from here. The only option off by default is for App notifications.

7. If you enable “App notification sync,” you will need to give Cortana permissions to read and control notifications on your phone.
8. You can then select exactly which applications will be synched to your PC.
9. Once done you can exit out of Cortana.

Configuring Cortana on PC

1. Click the Windows button and type Cortana. Click the icon for Cortana and Search Settings.
2. Scroll through the settings list and look for Send notifications between devices
3. Click the switch to turn it on.
4. Sign in to the same Microsoft account you used in the previous section

Recently, several Windows 10 users have reported an issue with the Windows folder sizes in their PCs. If you are one of these affected users, read on as this post will walk you through fixing this issue. For instance, if you have a folder with 100 GB worth of data and when checking its size using its properties, you see the wrong size instead of 100GB. The size displayed will most likely be a random number which can either be bigger or smaller than the real size of the folder. This incorrect folder size issue does not happen to any specific drive or certain kinds of folders as any folder can be affected by this incorrect folder size issue. When you try to rename the affected folder, the size will change but its size still remains to be incorrect. The root cause of this particular issue is in Windows 10 itself. It is a known bug that came along with one of the latest Windows Updates which prevents the File Explorer to accurately read the metadata of a certain folder or file and leads to displaying incorrect and unexpected file sizes and the reason why you might also notice that your drive is also not correct. Since this is brought upon by one of the recent or latest Windows Updates the good thing is that Microsoft will most likely release a fix on its next upcoming updates but until then, you will be left with no choice but to deal with an incorrect folder or file size. To remedy that, here are some suggestions you can try that might fix the problem.

Option 1 – Try using the System File Checker

The System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be causing the incorrect folder or file size in Windows 10. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 2 – Try resetting Windows 10

To fix the folder and file size issue, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files. That way, you won’t have to deal with inaccurate folders or file sizes as you browse and use your files.

Option 3 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.

If your Windows PC encounters an error, it will display a Blue Screen of Death or BSOD error which usually comes up for a fraction of second and creates some logs or Dumps Files as what other user prefers to call it and then boots your PC suddenly. This process usually takes place quickly that most users find it hard to get the error code and won’t probably be able to check what really went wrong with their PCs. This is where the dump files come in. They are stored internally in your computer and can only be accessed by an administrator. They are classified into 4 main types and in Windows 10 they are either:

1. Complete Memory Dump
2. Kernel Memory Dump
3. Small Memory Dump (256 KB)
4. Active Memory Dumps

Dump Files are useful as they could help you in resolving the problem and so you need to configure your Windows 10 PC to create them but first, you need to make a system restore point. This is essential as you are about to modify some system files as well as critical Windows 10 settings. There are two ways you can create Dump files – first is by modifying the settings in the Startup and Recovery and lastly is via the WMIC command line. Refer to the instructions prepared below to be guided on how you can create Dump files after any BSOD error using these options.

Option 1 – via Startup and Recovery

• Type in “control panel” in the Cortana Search box and then click on Control Panel from the search results to open it.
• After opening Control Panel, you need to make sure that you view the contents by their Category then click on the header link which is labeled “System and Security” or you could also right-click on the This PC icon and then click on Properties.
• Next, select the Advanced system settings from the left panel. Once you do, a new and small window will pop up.
• Under the newly opened window, look for the section called Startup and Recovery and then click on the Settings button.
• And from the System Failure section, you can choose any option from the drop-down for Write debugging information such as:
  • None – this means that there is no dump file created by Windows
  • Small Memory Dump – this means that Windows will create a Minidump file on BSOD
  • Complete Memory Dump – this means that Windows will create a Complete Memory Dump file on BSOD
  • Automatic Memory Dump – this means that Windows will create an Automatic Memory Dump file on BSOD
  • Active Memory Dump – this means that Windows will create an Active Memory Dump file on BSOD

Note: The complete dump needs a page file that is allowed to be the size of the physical memory installed in your PC with a dedicated 1 MB of space for just the page header.

• Now once you have selected the most suitable option for you, just click on OK/Apply and then exit.
• Restart your PC to successfully apply the changes made.

Option 2 – via the WMIC command line

• The first thing you need to do to create Dump files via the WMIC command line is to tap the Win + X keys combination or simply right-click on the Start button and then select the Command Prompt (Admin) option. You could also type in “cmd” in the Cortana search box and then right-click on Command Prompt from the results and select Run as administrator.
• After that, type in any of the commands given below depending on your preferences so that your Windows 10 PC will be configured to create Dump Files:
  • No dump file: wmic RECOVEROS set DebugInfoType = 0
  • Small Memory Dump: wmic RECOVEROS set DebugInfoType = 3
  • Kernel Memory Dump: wmic RECOVEROS set DebugInfoType = 2
  • Complete Memory Dump: wmic RECOVEROS set DebugInfoType = 1
  • Automatic Memory Dump: wmic RECOVEROS set DebugInfoType = 7
  • Active Memory Dump: wmic RECOVEROS set DebugInfoType = 1

Note: A complete dump has to have a Page file which is allowed to be the size of the physical memory installed on your PC accompanied by a 1 MB space for just the page header.

• Now type in “exit” in the Command Prompt to exit it.
• Restart your PC to apply the changes made successfully.

Windows has a built-in Backup and Restore system so if the Windows Backup or Restore fails and you receive any of the errors 0x80070001, 0x81000037, 0x80070003, worry not for this post will guide you in fixing the problem.
