How to Deal With Error Code 42

If you encounter the CLOCK_WATCHDOG_TIMEOUT Blue Screen of Death error while using your Windows 10 computer then it is most likely caused by a specified processor which is not processing interrupts. This occurs when the processor is deadlocked or nonresponsive. Specifically, this kind of Stop error occurs when the processor is having a hard time with the cooperation of its threads and cores. The threads are the tasks performed by cores and some cores can have many threads at the same time. And this is where the problem begins – one thread is waiting for an adequate response from another thread or one kernel is waiting for a response from another kernel and those responses are not coming. In other words, when the processor is unable to continue the processing of tasks since its resources are occupied and are interdependent to get free, such a state is called Deadlock. The CLOCK WATCHDOG TIMEOUT bug check has a value of 0x00000101 which means that an expected clock interrupt on a secondary processor, in a multiprocessor system, was not received within the allocated interval. To troubleshoot the problem, you can check out the possible fixes provided below but before you proceed, make sure that you boot your computer into Safe Mode with Networking only.

Option 1 – Undo or disable overclocking if you have overclocked your system

• Go to the Start Menu and open Settings.
• Next, select Update and Security and go to the Recover tab.
• From there, click on Restart now in Advanced startup. This will restart your computer.
• Once you’re in the Advanced startup, go to Troubleshoot and then select the Advanced Options.
• From there, select the UEFU Firmware Settings.
• Now click on Restart. Once your computer has restarted, it will automatically open BIOS.
• From the BIOS, go to the Advanced tab and navigate to Performance and then look for Overclocking.
• Once you’ve found Overclocking, make sure that it is disabled. If it’s not, then disable it and then save the changes made by tapping the F10 key.
• Start your computer normally and check if the CLOCK_WATCHDOG_TIMEOUT 0x00000101 error is now fixed.

Option 2 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the CLOCK_WATCHDOG_TIMEOUT 0x00000101 Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 3 – Try to rollback, update or disable drivers

The next thing you can do to fix the CLOCK_WATCHDOG_TIMEOUT 0x00000101 Stop error is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 4 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like CLOCK_WATCHDOG_TIMEOUT 0x00000101. 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 5 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the CLOCK_WATCHDOG_TIMEOUT Blue Screen error.

Option 6 – Troubleshoot the BSOD error in Clean Boot State

You can also troubleshoot the Blue Screen error in a Clean Boot state. There are times when third-party applications cause BSOD errors. 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.

• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And to configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 7 – Try to update the BIOS

Updating the BIOS can help you fix the CLOCK_WATCHDOG_TIMEOUT BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

What is PyLocky ransomware? And how does it execute its attack?

PyLocky ransomware is a file-locking malware created in order to lock important files and demand ransom from victims in exchange for data recovery. This new ransomware uses the .lockymap extension in marking the files it encrypts. It starts to execute its attack by dropping the following malicious payload in the system:

Name: facture_4739149_08.26.2018.exe SHA256:8655f8599b0892d55efc13fea404b520858d01812251b1d25dcf0afb4684dce9 Size: 5.3 MB

After dropping its malicious payload, this crypto-malware connects the infected computer to a remote server where it downloads more malicious files and places them on system folders. It then applies a data gathering module used to gather data about the user and the computer. The malicious files that were downloaded earlier along with the data obtained are used for another module called stealth protection. This allows PyLocky ransomware to execute its attack without detection from any security or antivirus programs installed in the system. It also modifies some registry keys and entries in the Windows Registry such as:

• HKEY_CURRENT_USERControl PanelDesktop
• HKEY_USERS.DEFAULTControl PanelDesktop
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

Once all the modifications are carried out, PyLocky ransomware will begin encrypting its targeted files using a sophisticated encryption cipher. Following the encryption, it adds the .lockymap extension to each one of the encrypted files and releases a ransom note named “LOCKY-README.txt” which contains the following content:

“Please be advised: All your files, pictures document and data has been encrypted with Military Grade Encryption RSA ABS-256. Your information is not lost. But Encrypted. In order for you to restore your files, you have to purchase a Decrypter. Follow these steps to restore your files. 1* Download the Tor Browser. ( Just type in google “Download Tor“ 2‘ Browse to URL: http://4wcgqlckaazungm.onion/index.php 3* Purchase the Decryptor to restore your files. It is very simple. If you don’t believe that we can restore your files, then you can restore 1 file of image format for free. Be aware the time is ticking. Price will be doubled every 96 hours so use it wisely. Your unique ID : CAUTION: Please do not try to modify or delete any encrypted file as it will be hard to restore it. SUPPORT: You can contact support to help decrypt your files for you. Click on support at http://4wcgqlckaazungm.onion/index.php”

How does PyLocky ransomware spread over the web?

PyLocky ransomware spreads using malicious spam email campaigns. Creators of this threat embed an infected attachment to spam emails and send them using a spambot. Crooks may even use deceptive tactics to trick you into opening the malware-laden immediately which is something you must not do. Thus, before opening any emails, make sure that you’ve thoroughly checked them. To successfully obliterate PyLocky ransomware from your computer, refer to the removal guide laid out below.

• Step 1: Launch the Task Manager by simply tapping Ctrl + Shift + Esc keys on your keyboard.
• Step 2: Under the Task Manager, go to the Processes tab and look for the process named facture_4739149_08.26.2018.exe and any suspicious-looking process which takes up most of your CPU’s resources and is most likely related to PyLocky ransomware.
• Step 3: After that, close the Task Manager.
• Step 4: Tap Win + R, type in appwiz.cpl and click OK or tap Enter to open Control Panel’s list of installed programs.
• Step 5: Under the list of installed programs, look for PyLocky ransomware or anything similar, and then uninstall it.
• Step 6: Next, close the Control Panel and tap Win + E keys to launch File Explorer.
• Step 7: Navigate to the following locations below and look for PyLocky ransomware’s malicious components such as facture_4739149_08.26.2018.exe and LOCKY-README.txt as well as other suspicious files, then delete all of them.

%TEMP% %WINDIR%System32Tasks %APPDATA%MicrosoftWindowsTemplates %USERPROFILE%Downloads %USERPROFILE%Desktop

• Step 8: Close the File Explorer.
• Step 9: Tap Win + R to open Run and then type in Regedit in the field and tap enter to pull up Windows Registry.
• Step 10: Navigate to the following path:

HKEY_CURRENT_USERControl PanelDesktop HKEY_USERS.DEFAULTControl PanelDesktop HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

• Step 11: Delete the registry keys and sub-keys created by PyLocky ransomware.
• Step 12: Close the Registry Editor and empty the Recycle Bin.

Try to recover your encrypted files using the Shadow Volume copies Restoring your encrypted files using Windows Previous Versions feature will only be effective if PyLocky ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot. To restore the encrypted file, right-click on it and select Properties, a new window will pop up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.

If you are using your Google Chrome browser and suddenly notice a constant flickering after you’ve upgraded your Windows 10 computer, read on as this post will help you sort out the issue. A lot of users have reported this screen flickering issue in Chrome after having upgraded their devices to a recent Windows 10 build. The bizarre thing about this problem is that it only affects the Google Chrome browser and when it occurs, the Chrome browser will start to flash or flicker. According to users who experience the problem in Chrome, it seems to get worse when they try to play videos on YouTube or other streaming sites. To resolve this problem, many users tried to use Chrome in Incognito Mode, cleared the browser cache as well as cookies. They even tried resetting the browser settings and reinstall Chrome but nothing seems to work. Worry not though as there are still other options you can try to fix the problem and they’re easy ones so you’ll have no problem following them. The screen flickering problem in Chrome appears to be related to the Windows background and color settings as well as incompatible display drivers.

• After that, select the drop-down menu and select Disabled.
• Then click on the “Relaunch Now” button.

BigTech platforms Google and Facebook were hit with a series of antitrust lawsuits by the US federal government and states on charges they are operating monopolies and abusing their power. Below is the status of the cases, as well as government probes of Apple and Amazon in their current states

Two lawsuits against Facebook

In a defeat, Judge James Boasberg said the Federal Trade Commission, which had sued Facebook in December asking that Facebook be forced to sell WhatsApp and Instagram, failed to show that Facebook had monopoly power in the social-networking market, among other problems. However, the FTC could file a new complaint by July 29. He threw out a related state lawsuit entirely, saying that the attorney's general had waited too long. They are looking at their options.

Four lawsuits against Google

The US Justice Department sued Google in October, accusing the $1 trillion company of illegally using its market muscle to hobble rivals. A trial date was set for September 12, 2023. A lawsuit by 38 US states and territories accuses Google of abusing its market power to try to make its search engine as dominant inside cars, TVs, and speakers as it is in phones. This was consolidated with the federal lawsuit for purposes of discovery. Texas, backed by other states, filed a separate lawsuit against Google, accusing it of breaking antitrust law in how it runs its online advertising business. Dozens of state attorneys general sued Google on July 7, alleging that it bought off competitors and used restrictive contracts to unlawfully maintain a monopoly for its app store on Android phones.

Justice Department investigates Apple

This probe, revealed in June 2019, appears to focus on Apple's app store. Some app developers have accused Apple of introducing new products very similar to existing apps created by other developers and sold in the Apple Store, and then trying to banish the older apps from the store because they compete with Apple's new product. Apple says it seeks to have only the highest-quality apps in the app store.

Justice Department probing Facebook and Amazon

In July 2019, the Justice Department said it was expanding its Big Tech probes to include "search, social media, and some retail services online", an apparent reference to Facebook and Amazon.

Federal Trade Commission on Amazon

In its investigation of Amazon, the FTC is likely looking at the inherent conflict of interest of Amazon competing with small sellers on its marketplace platform, including allegations that it used information from sellers on its platform to decide what products it would introduce.

If you’ve been using your Windows 10 PC for a long time now, you might have come across a couple of issues – from minimal ones to critical ones like the Blue Screen of Death or BSOD stop errors. One of these BSOD errors you can encounter is the DRIVER_IRQL_NOT_LESS_OR_EQUAL Blue Screen error. This particular BSOD error is caused by iaStorA.sys, iaisp64 sys, Netwtw04.sys, nvlddmkm.sys, ndis.sys, wrUrlFlt.sys, and other driver files on Windows 10. This error indicates that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high. When you encounter this error, just like a typical BSOD error, your computer will abruptly stop and you will see a blue screen with an error message saying:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (100% complete) If you’d like to know more, you can search online later for this error: DRIVER_IRQL_NOT_LESS_OR_EQUAL (wrUrlFlt.sys)”

The iaStorA.sys file is a software component that’s related to the Intel Rapid Storage Technology by Intel. It is a software solution supported by Intel Smart Response Technology which allows the PC to communicate with the hardware as well as externally connected devices. The Intel Rapid Storage Technology enables the Peripheral Component Interconnect Express or PCIe storage support, serial ATA RAID or Redundant Array of Independent Disks 0, 1, 5, and 10 support, and the PUIS or power-up in standby is also supported. To resolve this kind of BSOD error, you have to update, roll back or fresh-install the problematic driver. Refer to the options laid out below for detailed instructions.

Option 1 – Try removing the Intel Rapid Storage Technology or IRST drivers

The first thing you can try is to fix the Wi-Fi driver or the Ethernet driver on your computer to resolve the BSOD error. Take note that this option works not only on Windows 10 but also other Windows versions.

• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, click on the “IDE ATA/ATAPI Controller” entry and expand it.
• Next, right-click on all the driver entries that are appropriately labeled, and then click on Uninstall device.
• Now restart your PC and check if the problem’s fixed or not. If not, proceed to the next given option below.

Option 2 – Try updating the Intel Rapid Storage Technology or IRST drivers

If you’ve already tried uninstalling the IRST driver but you’re still getting the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error when you use your Windows 10 PC, then this means that the drivers might be corrupted or not compatible with the operating system version that you are using right now. So to fix the problem, you have to update your drivers. To do that, follow the steps below.

• The first thing you need to do is to go to your OEM’s website.
• Once you’re already on the OEM’s website, go to the Drivers section and get the latest version for your device and then try to overwrite it.

Alternatively, you can also update the drivers via the Device Manager:

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, click on the “IDE ATA/ATAPI Controller” entry and expand it.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Option 3 – Try using the System File Checker via Command Prompt

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 DRIVER IRQL NOT LESS OR EQUAL Blue Screen error. 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.

What is Out of Memory error while copying files? As you know, both the hard drive and RAM play a major role in performing any operation on a computer since every process or task that takes place in the system requires some RAM storage as well as hard drive storage to be executed. However, there are times when you may receive the following error messages when you try to copy files from one location to another:

“Out of memory or system resources, Close some windows or programs and try again.” “There is not enough memory to complete this operation – copying files.”

These errors are caused by the Desktop Heap limitation when there is no longer enough memory to complete the operation while copying the files. If you encounter any of these errors, you will be guided in this post with the help of some potential fixes that can increase its limit and will hopefully fix this error on your Windows 10 computer. You may try to close all the open windows and programs and then try copying the file again and see if that helps. If not, then proceed to the instructions given below. But before you do that, make sure that you create a System Restore point first. This way, you can undo the changes you’ve made any time in case there are some unwanted changes you want to reverse. After you create a System Restore point, refer to the steps provided below. Step 1: Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor. Step 2: Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems Step 3: Now double click on the DWORD named Windows to modify it. Step 4: Change the values for SharedSection in the Value Data field. It should be in the format of “SharedSection=aaaa,bbbb,cccc”. Note that you have to change the value of “bbbb” and “cccc”. So in case you are using an x86 operating system, set the value of bbbb to 12288 and then set the value for cccc to 1024. On the other hand, if you are using an x64 operating system, set the bbbb value to 20480 and the cccc value to 1024. Step 5: Exit the Registry Editor and restart your computer to successfully apply the changes made. Note: The bbbb value in the SharedSection registry is the size of the desktop heap for each interactive window station while the cccc section of the SharedSection value is the size of the desktop heap for each non-interactive window station. In addition, you must keep in mind that setting the value of bbbb to more than 20480 KB is not really recommended. On the other hand, there is another tool that could help in resolving the Out of Memory error. This tool is called the Memory Diagnostic tool in windows can help resolve the Out of Memory error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select your preferred option, your computer will restart and check for memory-based issues. If it finds any issues, it will automatically fix them.

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – 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 PFN_LIST_CORRUPT. 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 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• 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.

• Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. 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.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
• Then go to the Startup tab and select Microsoft OneDrive and then click Disable.
