Building your own custom PC system can be one of the greatest things you can do to your budget. Instead of going for a rebuild, we will go into detail about why building your own PC is a much better option. Also, note that if you do not possess enough technical knowledge about a topic there are plenty of stores that will offer you advice on components and after all, you can always get help from a friend.
So without further diversion from the topic, let us explore all the benefits of building a custom computer.
Building a custom PC is cheaper
At the first look, this statement does not feel right since when you look at the prebuilt systems you get a feeling that it is much cheaper than do it yourself variant and although CPU and GPU seem like a great deal I beg you to look under the hood on other components. Usually to lower price compromise would be made on other crucial components like SD or power supply, a PC case, or motherboard so even if you have a good CPU and GPU that will not matter much since other components would not be able to catch up with them. After all, prebuild computers will need to pay people who are building them and there is no way that will be cheaper if you just plain went and bought the same components yourself and install them.
When you are in control in choosing each component there is not only being cheaper online, it is flexibility with building itself. You choose which components you want to be stronger and which to be normal. Also, you can choose the exact model of the given component leaving you more in control and open to future upgrades.
More flexibility
Also, it may sound irrelevant but when building your own custom PC you can also choose which company you would like to purchase for each model, yes considering the CPU it is AMD or Intel but when you are buying a case, SSD, GPU, and other components choosing the right company for your needs is also the thing that should not be overlooked.
You can customize it the way you want
Not really a quality argument but with a custom PC build, you can choose would you like that RGB component or not, you choose do you like white or black fans, and many more things. You really can place a personal stamp on the computer making it indeed a personal computer.
You choose OS and applications
When you buy an already prebuilt PC, usually it comes with some sort of OS on it, sometimes it is freedos, Linux and sometimes it is Windows Home. When you get your hands dirty you can place whichever system you want on it and install applications that you use and know and some preinstalled typical apps.
Windows has a built-in Backup and Restore system so if the Windows Backup or Restore fails and you receive any of the errors 0x80070001, 0x81000037, 0x80070003, worry not for this post will guide you in fixing the problem. You might not be able to browse to the folders and files that you want to restore in the File Restore Wizard.
The cause of the error could vary depending on what error code you receive:
0x80070001 – If you got this particular error code when trying to back up a specific library or when you accept the default settings in Windows Backup and Restore.
0x81000037 – If you got this kind of error code when you try to read from the shadow copy on one of the volumes being backed up.
0x80070003 – If you got this error code when trying to restore the folders or files in a library by using the Windows Backup and Restore.
On the other hand, you cannot use the Browse for files or the Browse for folders functionality.
Note that the Windows Backup or Restore failed, Errors 0x80070001, 0x81000037, 0x80070003 Error code 0x80070001, 0x81000037 occurs during backup while Error code 0x80070003 and “Browse for Files” issue occurs when you try to restore files. Whichever error codes you got, here are some possible fixes that might help.
Option 1 – Fix Windows Backup error codes 0x80070001, 0x81000037
The reason for the Windows Backup error codes 0x80070001, 0x81000037, as mentioned above, is when there is a volume that uses a FAT file system (0x80070001) and when a volume contains compressed files (0x81000037). To fix these errors, you need to remove the “reparse point” also known as SYMBOLIC LINK, and select the absolute path of this location in the Windows Backup configuration user interface. Refer to these steps to remove the reparse point.
Tap the Win + R keys to open the Run dialog box.
Then type “cmd” in the field and hit Enter to open Command Prompt.
Next, type the following command and hit Enter:
DIR /AL /S
After you enter the command, it will display the JUNCTION list.
Now to delete the mounted volume reparse point, you have to locate the reparse point you found and right-click on the reparse point icon, and click on Properties.
Confirm that the folder Type is Mounted Volume in the General tab and then delete this folder.
Option 2 – Fix the Windows Restore Error 0x81000037
When you try to restore a deleted backed-up directory, it fails and the Error code 0x81000037 pops up. You can also encounter this error when you select to restore the files to their original subfolders check box in the File Restore Wizard and you try to restore folders or files to an alternative location, then you will encounter error code 0x81000037 which will be displayed in an error message as shown below:
To fix this error, you need to re-create the missing directory using the following steps:
Take note of the path for which the error occurs.
Then create the corresponding folder.
Now perform the restore operation again.
And since you might have subfolders in the deleted folder, click to clear the “Restore the files to their original subfolders” checkbox when you run the File Restore Wizard.
Option 3 – Cannot use the Browse for files or the Browse for folders functionality
There is no proper fix for this particular error but if you remember the name of the files, you can just search for them. Click on the Search button when using the File Restore functionality and then type the name of the file and when that file appears, select and click on it to restore it.
Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever.
Luckily we can easily change which application Windows uses for which file type.
Click on ⊞ WINDOWS to open the start menu and choose settings.On the settings screen, choose Apps.
When the Apps screen opens on the left click on Default apps.
On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.
Long working hours on a laptop can have some issues with laptop heating and thus slowing down. Today we will take a look at how can you prevent it from heating and keep it in a normal temperature range so it lasts longer and works better.
Close unnecessary programs or browser tabs
Usually, the main reason for high laptop temperature is the heavy and constant workload. Of course, the solution is very simple, turn off unnecessary browser tabs or applications running in the background, and less power will be needed for operation thus directly reducing workload and temperature.
Place it on a hard flat surface
Laptops generally have vents on the side and even under them, these vents, of course, are made so hot air is disposed of through them but if they are covered that will create issues. Placing computers on textiles, pillows, and legs can obstruct their venting holes and increase heat also since they are materials that are not taking heat away.
Your best practice should be placing the laptop onto a hard flat surface so air can flow freely and if you need to keep it in your lap there are lap desks made for this purpose.
Clean the laptop
With some good cleaning, the laptop can stop overheating, and generally, it will be cooler. Vents that has for ventilation can get clogged over large periods of time due to dust which is always present. Compressed air can be a quick easy solution to open the vents and redust it. Other methods include a compressor, vacuum, or brush in order to quickly remove any dust clogs. Taking it into service for complete redusting and paste change is also a great option.
Place it on the dedicated pad
There is some disagreement about using dedicated cooling pads for laptops, some say they are not effective at all, and some swear by them but from my experience good paired laptop and pad can indeed help with cooling it down. Usually, cooling pads will come with fans that will take away heat from the laptop itself reducing its overall heat.
Change your Windows power plan
If your laptop is constantly hot but you are not doing much with him check Windows power settings. There is a good chance it is set to run on a high-performance plan and if this is the case switch it back to a balanced power setting. Power plan like high performance will drain more power and more power will mean more heating. Of course, this will affect performance as well but for regular work that excludes some power gaming, video, and picture manipulations and other demanding tasks this power plan will work just fine.
Take control of the fans inside your laptop
Internal cooling is important and sometimes fans are not running to their full capacity so increasing their speed or changing their plan of work can cool down the computer nicely. Some laptops have fans controlling application already on them, especially gaming laptops but most of them do not. If your laptop does not have it, go to your laptop brand website and see if such an application exists for your model, if it does, download and install it but if there is no such application try general free ones like SpeedFan or Argus Monitor.
Reduce voltage of CPU and GPU
How more power means more heat, reducing the power that CPU and/or GPU take can be reduced inside BIOS by lowering voltage of these 2 components. First, go to BIOS and write down the voltage that is currently assigned to your CPU and/or GPU so you can bring it back if ever needed, also take note that reducing voltage and thus power will not affect negatively your components but increasing it thus overclocking can and will so be careful when bringing voltage back not to overdo it. You can always also reset your BIOS settings to bring them back to factory settings.
Do not use the laptop when charging it
When the laptop is placed on the charger in order to be charged and used at the same time, more power is drawn to it, and since the battery is taking electric charge instead of providing it more heat will be generated now since two different sources will be generating it, the battery itself and computer. When you really can not wait for the laptop to be charged, use it, but turn it off and wait to be fully charged if you can.

There are several kinds of errors you could encounter when you are running Windows 10 on a virtual machine. The Windows OS knows the difference between booting up in a standalone computer or in a virtual machine. This is why some specific drivers and system capabilities are used while emulating the Windows OS on software and during this phase, there are times when the System Preparation may throw up an error that says, “A fatal error occurred while trying to sysprep the machine”.
This kind of error arises due to a race condition wherein the Sysprep command tries to stop the Microsoft Distributed Transaction Coordinator or MSDTC service and the VMware tool tries to start the MSDTC service. You may also see the following messages logged in the Setuperr.log file:
[0x0f0082] SYSPRP LaunchDll:Failure occurred while executing ‘C:Windowssystem32msdtcprx.dll,SysPrepDtcCleanup’, returned error code -2146434815[gle=0x000000b7]
To fix the 0x0f0082, 0x0f0070, 0x0f00a8 Sysprep errors, you can check out two potential fixes. First, you have to check the status of the MSDTC service and the second one is to check the settings in the Windows Registry. Note that these fixes are proven to be effective on many users and apply to several versions of Windows, including Windows 10.

Hello and welcome to our Increasing Virtual Memory tutorial. Before trying to raise the quantity of virtual memory in your pc system, it's important to get a comprehension of its goal and use.
This leads to the constant use of high-performing tasks in addition to keeping multitasking capability.
The downside to this process is the fact that relatively, the HDD accesses information slower than a RAM module.
Taking into consideration its use in a computer program and how virtual memory works, there isn't any amount of virtual memory allocation.
The quantity of virtual memory to be defined for a unique computer program would be determined by the kinds of programs that are started and the quantity of multitasking done. The Microsoft Windows operating system yet does supply a recommended baseline memory based on the number of RAM installed and storage space of the HDD.
Virtual memory allocation really indicates the upsurge in how big the paging file is. This file provides the pc program with all the essential instructions on the best way to act once all the installed RAM has been allotted to the running applications. In both Microsoft Windows XP (all variants) and Windows Vista environments, the method to control the paging file size is basically the same. To increase the quantity of virtual memory:
Click on the Start menu and choose the "Control Panel" alternative. When the Control Panel window is started, choose the "Operation and Maintenance" class.
Click on the "System" choice to create the Device Properties Window.
Click the "Advanced" tab and choose the "Settings" button under Operation. In the Operation alternative window, select the "Change" button under the Virtual Memory class.
Choose the hard disk where the Windows operating system is now installed. That can be the same place where in fact the paging file will be saved.
Test on the checkbox for the "Custom Size" to enable you to determine the number of virtual memory you need to use for your device.
Click the "OK" button thrice to shut all of the windows. Click the Start button and restart your machine to enable the upsurge in the number of virtual memory to be finished.
In establishing the number of virtual memory, you'll have to place a maximum value along with an initial. It is suggested that both values be equivalent in order to achieve the finest performance on your pc system.
