VirtualBox displays Black screen

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue.

There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

  • In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
  • Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
  • Click the OK button and then restart your computer.
  • Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

  • Open VirtualBox on your computer and select the virtual machine.
  • Next, click on the Settings button and go to the Display section.
  • After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
  • Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.

3 Methods To Fix Qtcore4.dll Error

Qtcore4.dll Error - What is it?

Qtcore4.dll is a dynamic link library file that helps Microsoft Windows in loading several key components of the system. The Qtcore4.dll error occurs when the Qtcore4.dll file cannot be loaded to run the application supported by this .dll file. The Qcore4.dll missing error message may occur while booting your system or launching a certain program. It is a blue screen of death error type. The Qtcore4.dll error code is often displayed as:

BLUE SCREEN ERROR - QtCore4.dll Not Found

Filei386QtCore4.dll could not be loaded. The error code is 7. Setup cannot continue. Press any key to exit.

Solution

Restoro box imageError Causes

This error code is triggered by a variety of reasons such as:
  • Windows file allocation file gets damaged
  • Your computer BIOS (Basic Input/Output System) are misconfigured
  • The Qtcore4.dll file gets corrupt
  • Registry gets damaged and corrupt
  • Non-Microsoft program not running in tandem with Windows
  • Malware attack
  • Improper hardware driver software
It is advisable to fix the Qtcore4.dll error code immediately as this error can pose serious threats to your system. Qtcore4.dll error can lead to system breakdown.

Further Information and Manual Repair

Here are some ways of fixing the Qtcore4.dll error on your system:

1. Re-install the Program Causing Qtcore4.dll error message to pop up

As dll files are shared files sometimes due to program deletion and installation .dll file settings can get misconfigured, damaged, and corrupt. In such a scenario, you can try reinstalling the program that is causing Qtcore4.dll error message to appear on the screen.

2. Reconfigure your Mis-configured BIOS

If BIOS misconfiguration is the cause of this error code on your system, then try reconfiguring your system’s misconfigured BIOS.
  • To do this boot the computer and then press the BIOS designated keys to enter the BIOS. The keys may vary from manufacture to manufacture but typically, the setup keys are F2, F10, F12, and Del.
  • Once you figure out the setup keys, press them rapidly when booting the computer.
  • After successfully hitting the setup keys, the BIOS will load and you will see the BIOS setting menu on your screen. Adjust settings. Go to SATA Operation and change RAID AHCI to RAID ATA. Save changes and then exit.

3. Scan Your PC with a Registry Cleaner and an Antivirus

However, after adjusting the BIOS if the error still pops up on your screen, then this indicates the problem is bigger than you think. It triggers either malware attack or registry corruption. If these are the underlying causes for the Qtcore4.dll error on your system then you need to scan your PC with a registry cleaner and an antivirus. Registry is the main database of your system; if this gets corrupt it is most likely to result in system failure and valuable data loss. And as for malware, the biggest concern is data security threats. Today’s advanced and lethal malware like viruses and spyware can give easy access to hackers to enter your system from a remote location, browse through your confidential and private data and manipulate it to their advantage. This has led to a surge in various types of cyber crime, data breaches, and identity theft cases over the years. To avoid all this while resolving the error code Qtcore4.dll on your PC, registry cleaning and repair and antivirus scan are needed. You can either download 2 separate tools on your system to scan your PC which by the way will take a lot of time and increase your chances of the system slow down or you can download Restoro.

Can’t connect to this network Windows issue
Internet connectivity issues like Can’t connect to this network present a complex problem with simple solutions for PC and laptop users. First, it is usually recommended that users rule out problems with the internet connection, router, and Wi-Fi settings before proceeding to troubleshoot settings on your PC/laptop. Once the rest are ruled out, we can then proceed with the following troubleshooting steps and guidelines to fix your wifi connection issue: The first step is to update your windows network adapter driver. Connectivity problems may arise if your network driver is not updated or if it is incompatible with the network adapter. To do so, you may resort to any third-party driver scanning and installing programs found online. This solution should resort if users don’t want the hassle of perusing through windows settings that users may not be familiar with. However, this solution requires a pre-existing internet connection other than wifi, so it is recommended you have a backup internet connection via ethernet. The second step is to uninstall the driver for your network adapter. This solution is to resort if there is an issue with the driver as restarting the PC after the following steps let windows reinstall the driver again:
  • Open the quick access menu on your keyboard by pressing the Windows key and X key at the same time and select “Device Manager” from the menu list.
  • From the list of devices, select “Network Adapters”
  • Usually on the top of the list is the Wireless Network Adapter
  • Right-click the Wireless Network Adapter and select the option to “Uninstall device”
  • You will be given a confirmation in a new separate window to proceed. Click “Uninstall” to proceed.
  • After completing the previous steps, try rebooting your Windows PC and reconnecting to see if it works.
A third step is to disable the 802.1 1n modes of your network adapter by following the next steps:
  • First press the Windows logo key and the X key at the same time to bring up the quick-access menu. And like the previous step, select “Device Manager”
  • From the list of devices, select “Network Adapters”
  • Right-click the Wireless Network Adapter from the drop-down menu and select properties
  • Under properties, select the “Advanced” tab then select the 802.1 1n Mode. To the right drop-down menu change the option to  “Disabled” and click “Ok”
  • After, try to re-establish the connection to see if the steps have worked.
In the event that any of the preceding did not fix your problem, it helps to take a second look at the router and network settings using the interface provided by your ISP. A simple reset to the back of your router often fixes the issue. Also, try to check if you have any other administrative capabilities over the network to determine whether your device, in particular, has been MAC filtered or if the frequency of your wireless adapter is not compatible with the broadcast frequency of your router.

Fix Out of Memory error while copying files
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.

How to Fix Windows 10 Error 0x80070426

Error Code0x80070426 - What is it?

When Windows evolved into Windows 10, the program known as Windows Security Essentials is no longer. It is now the program known as Windows Defender. When a computer is upgraded from a previous version of Windows up to Windows 10, the Windows Defender takes over and will replace the Security Essentials. In a small percentage of Windows 10 upgrades, something will go wrong and the new program will fail to replace Security Essentials. The result will be that the operating system has both of the programs installed. In this case, Windows Defender will not offer any protection and Security Essentials will not be able to defend either. This error code will also present itself when the Windows Mail App in Windows 10 fail to retrieve and sync email from the user's account.

Common symptoms include:

  • There will be an error message that says: “An error has occurred in the program initialization. If this problem does continue, contact your System Admin. Error code 0x80070426.”
  • The computer will be left completely vulnerable to spyware and viruses.
  • The Windows Mail App will not be able to retrieve mail and will not sync with the PC user's mail.
  • The user can be doing anything on their computer and the error code will show up unprompted.
  • The computer will lock up, become slow, crash, or even freeze when dealing with error code 0x80070426.
  • The programs from an older version of Windows do not replace the newer version from Windows 10.

Solution

Restoro box imageError Causes

Error code 0x80070426 will present itself when a PC user has upgraded their OS from a previous version of Windows to the new Windows 10 version. When this happens, a small portion of users will experience the disconnect between older versions of specific programs, namely the virus protection. When the previous version of the program under a different name is not completely removed and the new virus protection program is installed, the programs will cancel each other out and collectively offer no protection.

This error code may also be found when Windows 10 tries to sync the user's email with the Windows Mail App.

Further Information and Manual Repair

There are a few methods to repair this problem. It should be noted that should anyone feel that the instructions are too complicated, they should contact a Windows repair technician to ensure that the error is fixed properly.

Method One: Uninstall Microsoft Essentials

Hold down the Windows Key and press R. Type in taskmgr into the run dialogue. You should locate the Windows Defender Service (this may show up as Windefend). Right-click on it and then choose Stop.

This will stop the program, but the program will start back up automatically when the computer restarts. While this program is stopped, uninstall Essentials.

To do this: go to Control Panel, Programs, and Features, Uninstall a Program. Alternately, you may hold down the Windows Key and press R, type in appwiz.cpl, click OK, and then locate Microsoft Essentials. Uninstall it, and then restart your computer.

After this is done, go to Settings, Update, and Security. Choose Windows Defender and ensure that Real-time protection is on. Refer back to the Task Manager, Services. Make sure that Defender service is on and running.

Method Two: If the problem occurs in the Windows Mail App

When error code 0x80070426 presents itself in the form of an error with the Mail app, it may be necessary to run an SFC scan.

Right-click on the Start menu or Windows icon, and select Command prompt. The command prompt may be navigated by using shortcut keys Win and X and then select it.

How to Fix Unable to contact your DHCP Server
If your IP address expires, you will most likely experience interruptions when browsing the web. In such cases, you have to release and renew the IP address by executing the following commands:
  • ipconfig /release
  • ipconfig /renew
So if you are trying to renew the IP address of your Windows 10 computer using the commands given above but you encounter an error message instead that says, “Unable to contact your DHCP Server”, then you’ve come to the right place as this post will guide you in fixing this error. This kind of error indicates that the NIC can’t communicate with the DHCP server which is why it’s not able to release new IP addresses. It could be due to many reasons. To fix this error, you can try to roll back, update or reinstall the Network Adapter drivers. You could also run the built-in Network Adapter troubleshooter, as well as start or restart the DHCP client service.

Option 1 – Try to rollback your Network driver

If you have updated the driver software as of late and you suddenly got this error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:
  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
  • Then select each one of them and double click to open a new mini window.
  • After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
  • Now restart your computer to successfully apply the changes made.

Option 2 – Try to update the Network drivers

If rolling back to the previous version of the Network adapter drivers didn’t help, then you need to update them instead. To do so, here’s what you have to do:
  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
  • Then right-click on each one of the Network drivers and update them all.
  • Restart your PC and see if it helped in fixing the BSOD error.
Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 3 – Run the Network Adapter troubleshooter

Running the built-in Network Adapter troubleshooter can also help in fixing the “Unable to contact your DHCP Server” error. To run the Network Adapter Troubleshooter, refer to these steps:
  • Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
  • Next, scroll down and select the “Network Adapter” option from the right pane.
  • Then click on the Run Troubleshooter” button.
  • After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
  • Restart your computer.

Option 4 – Try disabling the IPv6 in the Network Center

  • Tap the Win + X key combination and click on Network Connections.
  • This will open the Settings app on a specific page. Now on the right-side panel, click on the Network and Sharing Center link.
  • After that, it will open the Control Panel and from there, click on the network that your computer is connected to and then click on Properties.
  • Next, uncheck the entry that says, “Internet Protocol Version 6 (TCP/IPv6)” in the list that populates.
  • Now click on OK and close all other windows.
  • Restart your computer and see if the error is now fixed.

Option 5 – Start or restart the DHCP client service

If the DHCP client service is either inactive or stopped, you can try to start or restart it to resolve the error. You can do this via the Services Manager.
  • Tap the Win + R keys to open the Run utility.
  • Then type “services.msc” in the field and tap Enter or click OK to open the Services Manager.
  • After that, look for the DHCP client service from the list of services displayed.
  • Once you found it, right-click on it and select the Start or Restart option.
