Kernel_Data_Inpage_Error - What is it?

Kernel_Data_Inpage_Error is a BSOD (blue screen of death) error. Also, know as a 0x0000007A Stop error. This bug check indicates that the requested page of kernel data from the paging file failed to be read into memory. In simple words, this means that Windows has trouble reading from the memory. This can apply to both kinds of memory: stored memory on your hard drive and also the dynamic memory in your RAM. The Kernel_Data_Inpage_Error turns your computer screen all blue, stops the program being executed, and sometimes even leads to abrupt system shut down.

Error Causes

Kernel_Data_Inpage_Error may occur due to numerous reasons. The exact cause of this error can easily be found by going through the code displayed in the parameter of 0x00000007A. Let’s take a look at Kernel_Data_Inpage_Error parameter codes and the underlying causes of its occurrence:

• 0xC0000009A- This parameter code triggers missing nonpaged pool resources
• 0xC0000009C- This represents the installed hard disk drive has bad sectors.
• 0xC0000000E- This indicates a hardware failure or an incorrect drive configuration

Further Information and Manual Repair

No matter what the cause for Kernel_Data_Inpage_Error may be, it is advisable to fix it immediately as blue screen of death error codes are considered to be critical PC errors that can cause serious damages and even result in valuable data loss. Here are a couple of ways to repair this issue on your system:

1. Call the ‘Chkdsk’ (check disk) command on your system.

Windows XP, Vista, and 7 users can call this command, by pressing Windows Key +F and type in ‘chkdsk’ and run. However, you can’t run it while actively using Windows but you can always schedule it to start automatically the next time your computer turns on. Wrap up what you need and then reboot. Chkdsk disk checking process can take a long time, especially on large and slow hard drives. To run this command on Windows 8, open Windows search by pressing Windows Key+ F and then type ‘cmd’. Then right-click on the command prompt and choose the option ‘Run as Administrator’. To continue with the disk checking process, here you will be prompted to provide your administrator authentication. Once you insert the administrator authentication, type the command ‘Chkdsk C:/f/r/x” where the letter ‘C’ indicates the drive you want to examine and repair. Run it to scan for Kernel_Data_Inpage_Errors on your system. Chkdsk command will detect and repair errors on the hard drive and then automatically reboot.

Limitations to this Solution:

‘Chkdsk’ is a value-adding inbuilt disk checking tool in PC new Window versions; nonetheless, this command has certain limitations. It is time-consuming. You may have to wait for a long time for it to scan your system. Also when disk check is running, you will have to stop all other activities on your system. Furthermore, Chkdsk does not scan and fix all registry errors and other PC-related errors. So, you can’t be 100% sure that it will resolve all the Kernel_Data_Inpage_Errors on your PC.

Manually cleaning your PC registry may be the worst or best thing you ever decide to do. Registry keys that lie around on your computer, unused, can cause your computer to lag. This can end up in your computer not being able to load the easiest of programs and being slow at loading anything, let alone something that would take up a decent amount of memory. If your computer has slowed to almost an absolute stop, it is most probably the registry’s fault and the only option then is to clean it. You can get programs to do this for you, but they can be riddled with inaccuracies and viruses that could harm your computer even more. This is why some people choose to manually edit their computer. However, this is not without its flaws.

Registry Keys

Registry keys tend to have really long names. These names will be full of numbers and hyphens and will most likely give you no indication of what they do. Even some computer experts find it hard to understand what every computer’s registry keys do. This can make it very hard to see which ones are causing the problem; and if you don’t know what’s causing the problem, then there is no way you will be able to fix it. Some registry keys will be completely menial in what they do but some could be vital to even allow Windows to work on your computer.

Manual Registry Repair

Registry keys can also cause huge problems if you manually delete the wrong one. A lot of registry cleaners have the option to revive a key that they have deleted on you, which means that fixing an error that they made would be easy enough to do. However, when you manually delete registry keys, it will be an awful lot harder to get them back to work again afterward. This can cause your computer many problems and if you delete even one wrong key it is possible your computer will not even start. With the horrid naming system they have as well, it makes it very hard to determine what is important and what is not, which means it is all too likely that you will delete something important. However, those are the risks you have to take when you are cleaning out your registry. A registry cleaner has the same likelihood of messing with your computer and deleting something wrong that you have, so it is the same either way however a registry cleaner will do it with less hassle. But, some people say that if you do it yourself, it’s more likely to be right; that is why they prefer to do it manually and that is alright.

Conclusion

So, if you are manually deleting your registry keys that are unused, you’ll have to use a program that comes with Windows known as ‘regedit.exe’ which is incredibly difficult to use but may just be worth the hassle in the end. So, you don’t really need to put up with a slow computer, but be careful when messing with your registry manually!

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.

• 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.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.
