Computer crashes are one of the most annoying things that can happen to users. It often loses your data and work, you must spend extra time if you were in the middle of something and can even break Windows itself. Before we move to the article I just want to say that technically there are no random crashes, there is always a reason why the system hangs up, why you received blue screen, annoying restarts out of nowhere and many more PC crashes. In this article, we will explore many possible reasons why something may occur and offer you straight forward solution on how to escape the situation and prevent it from happening again. Without further delay, let's begin:

1. Check switch connectors and power outlets

   Yes, sometimes the most basic approach provides the best results, check to see if your power outlet is stable and providing you with constant voltage, if not, maybe you want to invest in a UPS system so you do not face random shutdowns and restarts during work, also while you are at it, check to see if that reset and power switch are connected properly and that they are not dirty or loose.

2. Clean your PC and check connectors

   Dirt can cause many issues with computers, from overheating to shutdowns to blue screens and memory dumps, check to see if your computer is clean enough and that all connectors are connected tight into their respective sockets.

3. Check the temperature of your CPU

   CPU overheating can cause so-called random freezes and blue screens, the computer might shut down or restart also without any visible reason. Check to see if your fan on the CPU is working properly and change the thermal paste if needed.

4. Check the health of your hard drive

   If your hard drive is beginning to go down the path of dying out, many issues can come from this condition. There are many tools on the internet and in Windows itself to check if your hard drive is working properly.

5. Run antivirus and firewall

   Random lock-ups or similar issues can also occur if by any chance you have some malware on your system, run protection software, and keep it updated to make sure the issue does not come from the computer being infected with malicious applications.

6. Keep system clean

   Have a habit to clean regularly system files and registries, keep removing unnecessary files from your computer and regularly update your Windows and applications along with drivers.

7. Run memory test

   Bad RAM bank can cause many issues during the work, check it out to be sure the problem is not RAM itself.

8. Do not run applications that are too demanding for your system

   Some applications require stronger hardware, and some require the latest hardware, if your computer is a little outdated, running a demanding application can cause issues like freezing, restarts, etc.

9. Remove applications you do not use

   This does not seem like anything important but if you are not using a specific application just remove it from the system, why? Sometimes an application has some ties to certain services and if it is outdated can cause issues for newer ones.

10. Stop installing everything you find on the internet

    Yes, that extension for chrome looks cool, yes, that fancy new player seems sick but if it is from an unverified source and from the unknown publisher without any reviews maybe you are better off with it. You can never tell what you might be placing into your system from the internet.

And that's it, 10 reasons and solutions on what to do on random computer freezes, crashes, etc.

Error 0x80070780 is a particularly nasty error since it means we can not access files on our hard drive. This might be an important file from work or anything similar and it can be frustrating when we can access it. In this article, we will address solutions to this error so you can continue with your activities where you have left off. Follow the guide step by step in the given order to minimize file damage and find the solution quickly.

1. Run File and Folder built-in troubleshooter

   The simple and clean solution, try first by running Windows built-in tools. Leave troubleshooter to scan and attempt repairs and try to access a file after that.

2. Run disk checker

   Maybe the file is corrupted or slightly damaged but repairable, run a built-in Windows disk checker and let it scan and repair any error found. Try accessing your file after the scan.

3. Try copying file

   If the file is under a bad sector or cluster on a disk drive that could be a reason why you can not access it, try copying the file to another location and then opening it, if the operation fails, boot Windows in safe mode and try to copy or move file then. If you are successful with copying files in safe mode, reboot your computer and try to open the file.

4. Reinstall the driver for the hard drive

   Like when the driver for USB is not working and you can not access files same can happen on your hard drive. Go to the device manager and reinstall the driver for your hard drive.

If you are in the process of booting up your computer but suddenly encountered an error saying, “The Boot Configuration Data for your PC is missing or contains errors” with an error code of 0xc0000454, read on as this post will help you resolve the problem. The error code 0xc0000454 occurs when you boot your computer and when the Windows Boot Manager encounters an issue with the Boot Configuration Data or BCD. The error code 0xc0000454 (STATUS_INSUFFICIENT_NVRAM_RESOURCES) signifies that there are no sufficient NVRAM or Non-Volatile Random Access Memory resources to complete the API. NVRAM is a component of the system based on the software that stores the Boot Configuration Data in an operating system. Usually, a simple restart can resolve the problem. However, if you’ve already done that and it’s of no use, then there are other potential fixes you can check out to troubleshoot the problem. To resolve the error code 0xc0000454, here are some potential fixes that should help:

Option 1 – 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 2 – 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.

• After that, click on Repair your computer located on 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 3 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 4 – Try to reset the BIOS

If updating the BIOS didn’t help in fixing the error, you can try to reset the BIOS instead.

• Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
• Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
• Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
• Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Booting the Windows computer system includes loading it from the various boot devices such as drivers, network as well as USB drives when the computer is turned on. The instant the startup sequence is done loading the operating system the system hardware will be ready to perform some complex operations – in this process, the Boot Log in Windows 10 is a record that maintains the list of success or failure of many pieces of Windows 10 system during the booting process. In other words, the Boot Log is the one that keeps a record of all that has happened while loading from the computer storage system to the memory during the boot process. It is available for several devices like network, hardware devices, and the operating system which assist in detecting issues during the boot process and other issues with regards to troubleshooting. Through Boot Log, you’ll know which drivers were unloaded and loaded from the start of the system during the boot process. You have the option to either disable or enable this feature on your Windows 10 PC. Named as “ntbtlog.txt”, the log file lists all the successfully loaded processes and the unsuccessful ones during the boot process. It is saved to the drive C:Windowsntbtlog.txt. As mentioned, you can enable or disable this feature in two ways – the first one is by using the System Configuration or MSConfig while the second one is using the Command Prompt. In this post, we’ll show you how you can enable or disable Boot Log in Windows 10 either way.

Option 1 – Enable or Disable Boot Log using System Configuration

Enable Boot Log:

• Tap the Win + R keys to open the Run dialog box.
• Then type in “msconfig” and click OK to open System Configuration.
• After that, go to the boot tab and check the checkbox labeled “Boot Log” under the Boot options so that you can enable the Boot Log feature.
• Then click on OK to save the changes made.
• Next, click on the Restart button in the prompt window to get started with the Boot Log process.
• After restarting your PC, go to C:Windowsntbtlog.txt to open the boot log.

Note: As pointed out earlier, the log file contains a list of all the successfully loaded drivers and also the list of drivers that failed to load during the boot process and every time you restart the system, the boot log file will keep on updating and will eventually increase the list of entries. For you to locate the drivers and make your troubleshooting a lot easier, I advised disabling the boot log after troubleshooting. To disable the boot log using System Configuration, refer to the steps below. Disable Boot Log:

• Tap the Win + R keys to open the Run dialog box.
• Then type in “msconfig” and click OK to open System Configuration.
• After that, go to the boot tab and unmark or uncheck the checkbox labeled “Boot Log” under the Boot options so that you can disable the Boot Log feature.
• Then click on OK to save the changes made.

Option 2 – Enable or Disable Boot Log using Command Prompt

Enable Boot Log:

• Go to the Start Menu and then type in “command prompt” in the search bar.
• After that, right-click on the Command Prompt option and select the “Run as administrator” option.
• After opening Command Prompt, type in “bcdedit” and tap Enter.

Note: You have to find the Identifier of the current operating system first to enable the Boot log. You can find it under the Windows Boot Loader section in the “Description” field and in this case, it’s Windows 10. You can also find the operating system identifier under the Windows Boot Loader section next to the field name identifier.

• To check if the boot log entry is disabled or enabled, go check the “Bootlog” field under the Windows Boot Loader. And if it turns out that the “bootlog” entry is enabled, the entry will be “Yes”. Otherwise, the entry will be “No”.
• Next, type in the following command with the operating system identifier to enable the boot log.

bcdedit /set {identifier} bootlog Yes

Note: In the command given above, make sure that you replace the given system identifier with your computer’s system identifier. For instance: In this example, the identifier was replaced with the actual operating system identifier as current.

bcdedit /set {current} bootlog Yes

• Afterward, restart the system to start the Boot log process.
• After the restart, go to C:Windowsntbtlog.txt to open the boot log.

Note: Every time you restart your computer, the boot log file will keep on updating which will increase the size of the log eventually. So if you want seamless and easier troubleshooting, it is advised to disable the Boot log after you troubleshoot. To disable it using the Command Prompt, here’s what you have to do. Disable Boot Log:

• Go to the Start Menu and then type in “command prompt” in the search bar.
• After that, right-click on the Command Prompt option and select the “Run as administrator” option.
• Once the Command Prompt is opened, type in the following command and then tap Enter to disable the boot log feature.

bcdedit/ set {identifier} bootlog No

Note: In the command given above, you need to replace the given system identifier with your computer’s system identifier. For instance: In this example, the {identifier} was replaced with the actual operating system identifier as {current}.

bcdedit /set {current} bootlog No

• Now close the Command Prompt.
