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.
Google Chrome 94 is here and it has introduced a controversial idle detection API. For those people that do not know what idle detection API is, well basically Chrome can be asked by a website to report when a user of the site has a site open and is idle on the device. The issue that people have with this is that this particular feature can be used to report when the user is not using a computer at all.
Good thing is that website or web application will prompt you to allow it to use this feature like when a site/application wants to use your microphone or web camera. Developers are on board with this feature since it can provide them with more telemetric data on how users are interacting with their website/application but there are some that are strongly voicing against this.
Tantek Çelik, Mozilla Standards Lead, commented on GitHub, saying:
As it is currently specified, I consider the Idle Detection API too tempting of an opportunity for surveillance capitalism motivated websites to invade an aspect of the user’s physical privacy, keep long-term records of physical user behaviors, discerning daily rhythms (e.g. lunchtime), and using that for proactive psychological manipulation (e.g. hunger, emotion, choice)…Thus I propose labeling this API harmful and encourage further incubation, perhaps reconsidering simpler, less-invasive alternative approaches to solve the motivating use-cases.
Others who have spoken against this feature are people from the WebKit development team inside Apple. Ryosuke Niwa, an Apple software engineer who works on WebKit said:
That doesn’t seem like a strong enough use case for this API. For starters, there is no guarantee that the user won’t immediately come back to the device. Also, who is such a service supposed to know what another device user might be using at any given point? We’re definitely not going to let a website know all the devices a given user might be using at any given point. That’s a very serious breach of the said user’s privacy. It seems to me that such a suppression/distribution mechanism is best left for the underlying operating systems/web browsers to handle.
Of course, technology itself as always can be used for good or for bad and time will tell if this feature has brought good stuff or it has paved another brick in surveillance and privacy manipulation. As said for now option will prompt for agreement and let's hope that it will be used for good causes from this day into the future.
The error 0x0000001 also known as APC_INDEX_MISMATCH is one of the fatal errors that users encounter upon starting their computers. This error appears when there is a sequence mismatch in the driver or system file when it is disabling or re-enabling Asynchronous procedure calls. The mismatch happens maybe because of a virus or malware attack, not shutting down your computer properly and incomplete installation of the system files.
There are many ways to fix this error. The easiest way is to download a repair utility program. The use of these programs perfectly fits those that are not so technical. All you have to do is download the program and install it on your computer. As soon as it is installed, the program will now scan and diagnose your computer for any errors. After it identifies the errors, it will then repair your PC through either manual or automatic tools.
To those who are techie and enjoy the manual resolution, you may take advantage of Microsoft’s analyze debug extension which tells you the cause of the error. After determining the cause then you can now start fixing the error.
Check if Hardware is functioning properly. If the cause is due to a hardware malfunction, you will have to make sure that all the pieces you are using are working. All the wires should be attached to their respective ports. Not only that, but you also must make sure that before installing the hardware, it is compatible with the Windows version that is installed into your computer.
Use Compatible software. If the problem was caused by software or a driver, you can uninstall and reinstall it. Always make it a rule that whenever you install a program or new software to your computer, make sure it is compatible with your operating system and never skip a step during the installation process. You also have to see to it that the program you are installing does not contain any viruses, malware, or spyware that can be harmful to your computer.
Update your Drivers Regularly. In most cases though, the cause of the APC_INDEX_MISMATCH error are outdated device drivers. To resolve this, you will have to go to your Control Panel then look for Device Manager. As soon as you are in the Device Manager window, you can now see the different devices running on your computer. You right-click on each device and check the Properties. In the Properties window, click on the Driver Tab and look for the date when it was last updated. You can then go to the manufacturer’s website and compare the dates.
For a new Windows operating system, you no longer have to go to the manufacturer's website though. All you have to do is click on Update Driver and it will automatically search for updates online.
Use a Genuine Operating System. There are also cases where the 0x0000001 error won’t allow you to access your computer. In this case, we have to suspect that the problem could be in your Operating system. To resolve this, you can reinstall your Operating System or update your current operating system. Only use a genuine licensed Windows Operating System because this will not only protect you from Malware and Viruses but it allows you to get all the recent update available from Microsoft. Update your Windows 10 regularly by going to Settings > Windows Update > Check for Updates. You may also turn on the Automatic Update by going to the Advanced options is found on the Windows Update Page.
You can always get help online but it really helps to know the basics and determining the root cause of the error.
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.
Driver state power failure error can be linked to three things happening in your computer. Incorrect power settings, driver issues, or incompatible hardware. Sadly when this error happens you only receive a blue screen of death with this message:
Sadly receiving this blue screen does not really explain which of the three cases is the correct one and causing the unwanted issue.
That being said, this article will not offer you a direct solution this time, it will be more like a guide on what to check and to do in order to remove this error, reason for this is the nature of the error itself.
If your computer is booting properly and you can enter Windows without issues the first thing you can try is going into power options and set it to high performance, if you are on a laptop set high performance both ways, when plugged and when on battery. Power performance settings can reflect on some hardware and can cause mayhem. After setting reboot the computer and see if the error repeats itself.
If the error persists go to the device manager and see if there is hardware that has any kind of warning beside it. If there is, update the driver or remove the driver of the device to see if this fixes the issue.
If all of the previous two things fail there is another thing you could try. Turn off your computer and disconnect all hardware except the most basic one. Now, this may take a long period of time but boot your computer and then repeat this process but each time add a new piece of hardware to eliminate and find which one is causing the issue. When found try to see if it is repairable through driver updates or get a new device.
A lot of users have experienced various issues either in installing a Feature or a Windows Update. One of these errors is the one with the error code 0x80d02002. If you are one of the users who is facing this problem right now, then the working solutions given in this post will surely help.
The Windows Update error code 0x80d02002 indicates that Windows 10 fails to upgrade or install as there is some issue with the files that have been downloaded and Windows encounters an error in installing them. Thus, the best thing you can do in such a case is to start the installation from scratch but before you do that, here are some suggestions that might help.
Option 1 – Try to rename the SoftwareDistribution folder
The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.
Open the WinX Menu.
From there, open Command Prompt as admin.
Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauservnet stop bitsrename c:windowsSoftwareDistribution SoftwareDistribution.bak
After entering these commands, it will stop the Windows Update Service, the Background Intelligent Transfer Service, and rename the SoftwareDistribution folder.
Next, got to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauservnet start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.
Option 2 – Try to reset the Catroot2 folder
You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues including the Windows Update error code 0x80d02002. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process. So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.
Option 3 – Try running the DISM tool to fix the broken Windows Update client
The Windows update/upgrade error 0x80d02002 might be caused by some issues in the Windows Update client so you need to run the DISM tool to repair it. Note that you have to use another computer or another Windows from a shared network to fix it.
Option 4 – Try to run the Windows Update Troubleshooter
Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80d02002. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.
Option 5 – Try to run Microsoft’s troubleshooter online
You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.
USB Kill, a USB device is able to fry and damage your computer, mobile phone, router, etc. This device is quite dangerous and can kill electronics the moment it is inserted into an available port. By now people should know that they should not put unknown USB sticks into their devices because of potential virus and malware threats but this raises using unknown sticks to a whole new level.
Kill kits are not really new to the market, they have existed before but lately, technology really progressed and the latest USB sticks are really good, their success rate is around 95% which is pretty high and should not be taken lightly.
The second thing that you really should not play with strange USB sticks is that they dropped in price really hard, although top Kill kits will still go as high as around 300 USD, there are really cheap ones lurking in Ali Express that are just 6 USD!!! that makes them affordable devices for the mass market.
The device is made to take energy and current from the port it is plugged in, multiply it and release its charge back into the device, successfully frying some components immediately. Some more professional Kill sticks can even fry devices even when the device itself is not powered and can be even started remotely.
The point of this article is to make you aware that you should not in any kind of circumstances use and plug-in USB sticks into your devices that you do not know where they come from, especially from the mail!!
Recently, a number of users reported that their Google Chrome browsers keep on opening new tabs no matter what they do. This issue could be due to lots of reasons but the main ones are corrupt installation, background applications, adware, dubious browser extensions, malware, and so on.

Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.
Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.
So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.
SONY PLAYSTATION VR
If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.
While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.
VALVE Index
Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.
The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.
However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.
META QUEST 2
Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.
Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.
Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.
Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.
Every computer has to have a graphic card, it is one of the essential components in order for the computer to work. If you have a second-hand computer, got one as a gift, or similar, there is a high chance that you do not really know which components are inside. Luckily finding out which graphic card you have inside is quite easy.
Right-click the taskbar and select Task Manager
Click the Performance tab at the top of the window, if you don’t see the tabs, click “More Info.” Select “GPU 0” in the sidebar. The GPU’s manufacturer and model names are displayed at the top right corner of the window.
You’ll also see other information, such as the amount of dedicated memory on your GPU, in this window. Windows 10’s Task Manager displays your GPU usage here, and you can also view GPU usage by application.
If your system has multiple GPUs, you’ll also see “GPU 1” and so on here. Each represents a different physical GPU.
The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list. On the other hand, while setting up several styles for the folder and file icons, some Windows 10 users have experienced some unusual issues where there is the Black background showing up behind folder icons. They tried refreshing the File Explorer a couple of times but it didn’t help in fixing the problem and the black squares are still visible on some folder icons.
The black squares behind the folder icons might look disturbing though it’s not really a big problem and is merely a graphical glitch that does not cause any damage or whatsoever to the content of the folder and files. The most likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches. In addition, graphical glitches like this one could also occur if you are using out outdated graphics drivers. To fix this problem, you need to follow the options laid out below.
Option 1 – Try using the Disk Cleanup to remove Thumbnail files
The Disk Cleanup tool is one of the options you can try to fix the black squares behind the folder icons. Through this tool, you can delete all the Thumbnail files on your disk. To use it, refer to these steps:
Open the Search bar and type “disk cleanup” in the field.
After opening Disk Cleanup from the search results, then from the drop-down menu select the C: drive to clean up and click OK.
Wait for the scanning process to complete. Once it’s done, select the files you want to delete.
Ensure that you select the box labeled “Thumbnails” under the Files to Delete section then click on OK.
After that, a confirmation box will appear, just click on Delete files to delete the files permanently.
Restart your PC.
Option 2 – Try resetting the Thumbnail cache
You have the option to manually delete the Thumbnail Cache to resolve the black square background behind the folder icons issue. Follow the steps given below to reset the Thumbnail cache.
Open the File Explorer.
Next, navigate to the View tab and select the option with Hidden items to display all the hidden folders and files.
Next, go to this path: C:Users<username>AppDataLocal
In the given path, make sure that you put your actual username in the username field. Then look for a file named “IconCache.db”. Right-click on this file and click on Delete.
After that, go to this path: C:Users<username>AppDataLocalMicrosoftWindowsExplorer
From there, select all the files and delete them.
Note: If a prompt appears saying, “The files are in use and cannot be deleted”, simply select the “Do this for all current items” option and then click on Try Again. If you get an error message, click on Cancel to close the window and restart your computer.
Option 3 – Try updating or reinstalling the Graphics driver
Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
