Simple Manual to Fix Corrupted PST Files Quick

As you know, storage devices are an important part of the computer system for porting, saving, and extracting data files. And for you to differentiate between storage devices on your computer system, each one of the storage devices is labeled with a unique number referred to as Disk Signature for identification. The unique disk identifier is stored as a part of the MBR or Master Boot Record. Disk signature is used by operating systems in order to identify and set apart different data storage devices and hard disk drives in the computer for data access. These days, Disk cloning has become a regular practice in upgrading to larger hard disk drives. Drives are cloned in order to produce a similar copy to use both the original drive and cloned copy together. Moreover, lots of virtualization tools are being used to virtualize the physical hard disk drives to create virtual hard disk drives and several virtual machine clones that are created with the existing virtual hard disk drives. And since these are identical copies, chances these copies may have identical disk signatures. As a result, when you use both disks that have identical signatures at the same time you run into the Disk Signature Collision problem. This kind of problem does not often occur as the Windows system does not really allow two disks to function simultaneously when they have the same disk signature. When you encounter a Disk Collision problem in your Windows 10 computer, you may see the following error messages:

• The boot selection failed because a required device is inaccessible
• The disk is offline because it has a signature collision
• This disk is offline because it has a signature collision with another disk that is online

You can fix the disk collision problem by changing the disk signature which you can achieve using the command line utility diskpart in Windows PowerShell or Command Prompt or using Windows Disk Management utility. To fix the disk collision problem, you can make use of the command-line utility called diskpart in Windows PowerShell or Command Prompt to view and change the signature, or can make use of Master Boot record in the Windows Registry. You can also make use of Windows Disk Management Utility to change the signature. Simply follow the given options below to change the disk signature either way.

Option 1 – Change Disk Signature via Diskpart

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• After that, type the “diskpart” command and hit Enter to open Diskpart.
• Next, type the “list disk” command to display all the disks available in the system.
• Next, take note of the problematic disk number with the status Offline from the list and then type the “Select disk x” command where x is the offline disk to select the offline disk. For instance, if you type “select disk 1”, it will display the “Disk 1 is now the selected disk” message.
• Now type the “Uniqueid disk” command to display the disk signature and to change the disk’s signature and set the disk online, type the “unique disk ID= (New signature)” where (New signature) is the new ID in hexadecimal. For instance, you can set the new id as “unique disk ID= 1456ACBD”.

Note: If you have given the wrong format ID, the command prompt will display the following error:

“The specified identifier is not in the correct format. Type the identifier in the correct format: in hexadecimal form for an MBR disk or as a GUID for a GPT disk.”

• After you’re done, the disk will be online, and then restart your computer.

Option 2 – Change Disk Signature via Disk Management Utility

• Tap the Win + R keys to open the Run dialog box and then type “diskmgmt.msc” and hit Enter or click OK to open Disk Management.
• Next, right-click on the disk that is marked as Missing or Offline.
• After that, select the Online command from the drop-down menu.
• Then from the selecting option Online, Windows will generate a new disk signature.

What exactly is no audio device malfunction?

No audio device error is among the malfunctions that many Computer consumers run into. No sound or audio can be heard from the computer when the error occurs.

Solution

Error Causes

There are numerous elements that may be the basis of this malfunction. Corrupted or broken sound card drivers, incorrect Device Manager Options for example, or even incorrect BIOS configurations.

Further Information and Manual Repair

How could you recover the standard production of audio by your personal computer and solve this malfunction? Like a number of additional malfunctions, the method of the repair depends on its trigger. To properly solve this dilemma, you are required to run through an evaluation of the pc system so that you can pinpoint the cause. This is because there are numerous variables, which alone, or concurrently may trigger this dilemma. These measures will allow you to work out the no sound device error in your personal computer programs, identify the trigger and fix it. Follow the directions in step 1 if your computer has an onboard audio device installed in it and assess the BIOS settings. You can jump step 1 and move to step two if you utilize a separate sound card.

STEP #1 - Assess the BIOS options.

No sound device error can be caused by incorrect BIOS configurations in your Personal Computer. By fixing these settings if they are the cause of the malfunction, you can easily solve it. Make Sure you restart the pc and immediately access the BIOS options. By locating the Sound card, which is usually known as the AC97 Audio, you should subsequently open the Integrated Peripherals. As soon as you locate it, set it to Allow or Auto. Finally, you should access the On-Board Audio AC97 Control and set it to Allow or Auto as well. If it doesn't solve the situation, proceed to Step Two.

STEP #2 - Analyze the Device Manager

No sound device malfunction can be additionally caused by malfunctions with the Device Manager. To solve this issue, go to My Computer, right-click it, select properties, click on the Hardware tab, then click on Device Manager. At this windowpane, analyze the movie, audio, and game controllers. If you learn that there is a cross on any of the sub things, right-click it subsequently and set it to Enable. The sound card driver may have not been correctly installed or may be damaged if there is Exclamatory Mark or Question Mark on the device manager menu. This does not mean that the sound card driver is ok. It may have malfunctioned even though you do not locate anything unusual. This is because the Device Manager doesn't always recognize errors in audio hardware. After this, you can proceed to step 3.

STEP #3 - Upgrade or reinstall the Sound Card Driver.

About 80% of "no sound system discovered/installed" malfunctions come from broken and/ or out-of-date card drivers. The sound card will not be detected by the Windows Operating System, when the audio card driver is corrupted, damaged, or out-of-date and therefore no sound will be produced by your computer. If this is the cause of the no sound device malfunction, you should reinstall the Audio Card Driver on your computer. Still, you can utilize driver upgrade applications on the web that will help you upgrade out-of-date drivers.

DLL files have certain functions that help the programs in the computer run properly. One of these DLL files is the Msvcr120.dll_clr0400.dll. This particular DLL file is responsible for the extraction of the required resources during the installation of a program and is used when the program is launched or when games are launched in the C++ language. However, a number of users recently reported that they’ve encountered an error that says, “Msvcr120.dll_clr0400.dll is missing” when they tried to install an application or when they tried opening an application. This kind of error could be due to several factors. It is possible that the DLL file is corrupted or there are some programs that interfere with the DLL file. On the other hand, it is also possible that it has been infected by a virus. To resolve this error, here are some potential fixes you need to check out:

Option 1 – Run System File Checker scan

• 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.

• Reboot your computer.

Option 2 – Troubleshoot the missing Msvcr120.dll_clr0400.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 4 – Try to replace the DLL file with a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:WindowsSystem32
  • x64: This PC > C:WindowsSysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 5 – Scan your computer using Windows Defender

8: Replace the Hard Disk

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• 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.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• 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 “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

Some Windows users are encountering the 0x800705b3 error code after failing to install a pending update on Windows 10. Most commonly this particular issue is reported to occur with Integrated webcam drivers updates and Bluetooth adapter driver updates. Follow the guide below in order to fix the issue and update your Windows successfully

Running the Windows Update Troubleshooter

The majority of users that were dealing with this issue reported that the issue was fixed after they ran the Windows Update Troubleshooter and applied the recommended fix.

1. Open a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘ms-settings:troubleshoot’ and press ENTER to open up the Troubleshooting menu. Opening the Troubleshooting tab on Windows 10
2. Once you’re inside the Troubleshooting tab, move over to the right-hand section of the screen and click on Windows Update (under Get up and Running). Next, from the context menu that just appeared, click on Run the Troubleshooter.
3. Once you’re inside the Windows Update troubleshooter, wait until the initial scan is complete and see if a viable repair strategy is found.
4. If the scan has identified a strategy with the potential to fix your ongoing issue, click on Apply this fix and wait until the procedure is complete. Applying the fix Note: Depending on the type of fix that was recommended, you might need to follow an additional set of instructions before the fix will be properly imposed.
5. After you’ve done this, reboot your computer and wait for the next startup to complete.
6. Open Windows Update once again and see if the installation of this pending update is now successful.

Installing the pending Update Manually

Whether you’re experiencing this issue with an integrated webcam driver or with anything else, chances are you’ll be able to circumvent the apparition of the 0x800705b3 error by using the Microsoft Update Catalog to find, download and install the pending update manually.

1. Open your default browser and navigate to the root web page of the Microsoft Update Catalog.
2. Once you’re inside the Microsoft Update Catalog, use the search function (top-right corner of the screen) to search for the update that is failing.
3. After the search is completed and you get the list of results, look for an updated driver version that is compatible with your Windows version and CPU architecture.
4. Once you manage to identify the correct Windows Update, click on the hyperlink associated with the update that you want to install, then click the Download button and wait for the process to complete.
5. After the download is complete, use File Explorer to navigate to the location where you previously downloaded the update.
6. When you get to the correct location, right-click on the .inf file and choose Install from the context menu that just appeared. Note: If you have multiple failing updates with the same 0x800705b3, repeat the instructions above with every Windows Update that you’re having trouble installing.
7. At the end of this operation, reboot your computer and see if the problem is fixed at the next computer startup.

Enabling the Windows Installer Service

The Windows installer service is responsible for installing pending updates that get downloaded by the Windows Update component. If this service is disabled on your configuration, none of the updates waiting to get installed will get completed.

1. Press ⊞ WINDOWS + R to open up a Run dialog box. Inside the text box, type ‘services.msc’ and press ENTER to open up the Services utility.
2. Once you’re inside the Services screen, move over to the right-hand tab of the screen, scroll down through the list of services and locate the Windows Installer service. When you find it, right-click on it and choose Properties from the context menu that just appeared.
3. Once you are inside the Properties screen of the Windows Installer services, access the General tab, click on the Start button to force-start the service. Note: If you can, also change the Startup type to Automatic via the associated drop-down menu. However, depending on your administrator settings, this might not be possible.
4. Restart your computer and wait for the next startup to complete. Once your PC boots back up, attempt to reinstall the driver that was previously triggering the 0x800705b3 error and see if the issue is now fixed.

Performing a Winsock Reset

In case the 0x800705b3 error is related to some kind of network inconsistency (TCP or IP related), you might see Windows Updates failing due to bad data that forces the Windows to abort the installation of new pending updates. In this case, you should proceed by doing a complete Winsock reset procedure to fix the majority of the socket and temporary data-related issues that might cause this behavior. Several affected users have confirmed that this method was the only thing that allowed them to finally fix the Windows Update issue and install pending updates normally. Here are some step-by-step instructions that will walk you through the process of performing Winsock Reset:

1. Open up a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘cmd’, then press CTRL + SHIFT + ENTER to open up an elevated Command Prompt. Accessing an elevated CMD prompt Note: When prompted by the UAC (User Account Control) prompt, click Yes to grant admin access.
2. Inside the elevated CMD prompt, type and taste the following commands in order and press ENTER after each one to effectively reset the TCP and IP data that might be responsible for the apparition of the 0x800705b3 error code:

   nbtstat -R
   nbtstat -RR
   netsh int reset all
   netsh int ip reset
   netsh winsock reset

3. Once every command above is processed successfully, you can go ahead and close the elevated Command Prompt and reboot your computer.
4. After the next startup is complete, repeat the installation of the Windows Update that was previously failing and see if the issue is now fixed.

Performing SFC and DISM Scans

If none of the ‘superficial’ causes have worked in your case, you should start considering some type of system corruption that might affect your computer’s ability to complete pending updates that are currently waiting to be installed. In case you find yourself in this particular scenario, you should run a couple of built-in utilities capable of fixing corrupted instances that might be currently affecting the Windows Update component. Our recommendation is to start with a simple System File Checker scan. An SFC scan will cross-check every Windows File against a local archive that maintains healthy copies. In case corrupted instances are found, this utility will swap the corrupted instance with the healthy equivalent.

Performing an SFC scan

Once the SFC scan is complete, reboot your computer and wait for the next startup to complete. After your computer boots back up, initiate a DISM scan. This utility works differently in the sense that it relies on a sub-component of Windows Update to download healthy copies for the corrupted Windows files that need to be replaced. Because of this, it’s important to make sure that you have a reliable Internet connection before initiating this operation.

Doing a DISM scan

After the DISM scan is complete, reboot your computer one final time and see if the issue is fixed once the next startup is complete.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

If your browser of choice is Google Chrome then sit back and enjoy the ride as we are going through some great productivity tips for it. So without further talking let's dive right into them.

Browsing using tabs groups in Chrome

This kind of problem typically occurs when you’ve disabled the Bluetooth option. However, this option is already enabled and you still encountered the same error message saying, “Check the PIN and try connecting again”, then you need to troubleshoot the problem further. In most cases, this kind of issue can be fixed when you restart your computer and go to the Windows Settings and select the “Add Bluetooth or other devices” option and then put the keyboard into pairing mode. And when the keyboard appears in the “Add a device” dialog box, just select it. On the other hand, if your Bluetooth keyboard won’t get connected to your Windows 10 computer and you encounter an error that says, “Can’t pair Bluetooth keyboard, Check the PIN and try connecting again”, then you need to check out the options provided below but before you do so, make sure that you create a System Restore point first as some of the troubleshooting options provided involves the Windows Registry.

Option 1 – Try to use the Device Pairing Wizard

The Device Pairing Wizard is the one that allows your computer to look for any new devices and display them underneath it. All you have to do to use this wizard is to follow its instructions to connect your Bluetooth device to Windows 10. To get started, follow these steps:

• First, tap the Win + R keys to launch the Run utility and type “devicepairingwizard” in the field, and then hit Enter to run the Device Pairing Wizard.
• After that, wait for a couple of seconds until the devices appear. Once they do, select the Bluetooth device you wish to add.

• Once done, tap Enter. This should help in pairing your computer to your Bluetooth keyboard.

Option 2 – Try to use the Registry Editor

The next thing you can do to resolve the pairing issue with your Bluetooth keyboard is to use the Registry Editor by following these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_USERS/.DEFAULT/Software/Microsoft/Windows/CurrentVersion/Bluetooth/ExceptionDB
• From there, look for the folder named “Addrs” and expand it. If you see any folders or keys under it, select them and delete them. These keys represent the MAC address of your Bluetooth devices.
• Once you’re done, restart your computer and try to pair your Bluetooth keyboard once more.

Option 3 – Try running the Bluetooth Troubleshooter

As you know, Windows 10 has various troubleshooters with user-friendly interfaces where you can utilize them to fix issues in your PC. And since you’re dealing with some Bluetooth problem, you have to run the Bluetooth Troubleshooter.

• Open the Windows 10 Settings.
• Then go to Update & Security > Troubleshoot.
• You should find the option for Bluetooth on your right-hand side – click on it then click on the “Run the troubleshooter” option.
• Now follow the next screen options.

Option 4 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since you have trouble pairing your Bluetooth keyboard, you can update, rollback, or uninstall the Bluetooth drivers. How? Follow the steps below.

• Tap the Win + X keys to open the Device Manager.
• Next, look for the Bluetooth device and right-click on it.
• Select the option “Update driver”.
