You have probably heard a lot of good things about gaming mice, how they are better feeling, better in any way possible and it is all true, everything you heard is actually true, they are superior in any way to a regular mouse but with one big disadvantage, and that would be the price. While you can find a regular mouse for pocket change, a gaming mouse is in comparison very expensive even for entry-level ones.

In this article we will explore all advantages and compare it with the regular one so you can come up with your own conclusion about do you really need one for yourself or if you are fine with regular.

Price

As stated price is one factor that does not favor gaming mice. Regular mouse for a personal computer goes around 10 or 20 USD, while entry-level in gaming one will be 40 USD and can go up to 250 USD, this large gap in price is usually determining factor why people pick up regular one. If you are on a really tight budget go for the regular one, but if you can afford a gaming one get it without second thoughts.

Software

This is where you will see the big difference between mice. Regular ones when connected are recognized and the driver is automatically installed and you can use it, same goes with gaming ones but with one big difference, you have an option to install additional manufacturers' software specially tailored for your mouse. In the application, you will be able to access some features that are specific to the mouse model that you could not set in typical Windows mouse properties. Beside more options software can also have features like setting your profiles and saving them to be recalled when you need them on the fly.

Sensitivity of mouse

The sensitivity of the mouse is measured in dots per one inch or short DPI, this is directly shown on your screen by how fast your mouse can move, higher sensitivity means your mouse will move faster across the screen and lower means it will move slower. All gaming mice come with buttons and settings that will allow you to change DPI on the fly and you can choose precise DPI settings in the software.

The regular mouse comes with DPI around 800 and goes to 1200 typically and does not have usually the option to change this while gaming mice start at 400 and can go as high as 26000 with the option to change it. Some regular mice can have only 1 option of DPI, usually very cheap ones.

Polling rates in mice

Pooling rate is the measurement of how often your mouse reports where it is positioned on the computer. The higher the pooling rate, the more responsive your mouse will be and vice versa. It is measured in hertz (Hz) and regular mice have them around 125Hz that is enough if you are using a computer for office, internet, and mail work.

If you are working in design or gaming you will need more than 125Hz polling rate, luckily gaming mice come with a minimum of 500Hz as an entry point and some hi-end models are going as far as 8000Hz. This very high pooling rate will get some extra load on your CPU but the mouse itself will be maximally responsive and will respond even to the smallest moves.

Ergonomics

Regular mice are well just mice, they are typical shape and size, gaming mice are made with ergonomics in mind. How they are made for extensive daily use of several hours per day they are constructed in a way to offer a pleasant and pain-free experience.

If you work on a computer for long periods of time consider gaming an ergonomic mouse since it will take the strain from hands and place them in a more natural position.

Macro keys

Gaming mice most of the time come with more keys compared with regular ones and good thing is that via its software you can tie certain actions to these extra keys making work or gaming more pleasant and quicker.

Components and material quality

In order to make regular mice more affordable and cheaper materials and quality of components had to suffer. Gaming mice have millions of guaranteed clicks by companies that make them before they break and regular ones usually do not guarantee a single one. This is due of course quality of materials that have been used in constructing these devices.

In the long term, if you use a gaming mouse for typical daily tasks it will outlive your regular one and on the side offer you more pleasant and responsive use along the way.

Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error.

One of the worst Blue Screen of Death errors you can encounter is the UNMOUNTABLE_BOOT_VOLUME BSOD on Windows 10. In this BSOD error, your computer won’t be able to properly boot. Meaning to say, even if you want to reinstall Windows, you won’t be able to back up your important files. Thus, it wouldn’t be really feasible to fix the system files, and besides, reinstalling Windows 10 would take a lot of time, not to mention resources. The UNMOUNTABLE BOOT VOLUME error is the kind of BSOD error that occurs if Windows is not able to access the volume that contains the boot files. Resolving this BSOD error won’t be easy but you will surely manage by following the suggestions laid out below but before you go on, make sure to create a System Restore Point.

Option 1 – Try checking the hardware

If you got the UNMOUNTABLE BOOT VOLUME BSOD error while trying to update your computer to a higher version of Windows, then you need to check if you have the compatible drivers for the disk controller as well as re-check the drive cabling and make sure that it is properly configured. And if you’re reusing either ATA-100 or ATA-66 drivers, ensure that you have an 80-connector cable and not the standard 40-connector IDE cable.

Option 2 – Try using Automatic Repair

You might also want to use Automatic Repair in fixing the BSOD error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 3 – Try fixing the Master Boot Record or MBR

The MBR or Master Boot Record is the location and is where the architecture of the operating system is installed. Thus, if either the location or the architecture has tampered with, it can cause lots of BSOD errors like the UNMOUNTABLE BOOT VOLUME error.

• Boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options.
• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

bootrec /fixboot

• After entering the command, wait until the process is completed and then restart your computer to apply the changes made successfully.

Option 4 – Run the CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you fix the UNMOUNTABLE BOOT VOLUME error. 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.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then reboot your PC.

Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working. When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below. Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:

• %userprofile%Desktopsfcdetails.txt
• Log %WinDir%LogsCBSCBS.log

Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file. Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter. Step 4: After opening Command Prompt, type and enter the command below to execute it:

takeown /f FileNameAndPath

Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:

icacls FileNameAndPath /GRANT ADMINISTRATORS:F

Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:

copy NewFileLocation FileNameAndPath

Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”

If your Windows 10 computer or laptop keeps on going to sleep randomly even when you’re using it, read on as this post will walk you through the process of resolving the problem. There are a number of users who reported about how their Windows 10 computers would automatically go into Sleep Mode. One particular user claimed that when he installed a fresh Windows 10 version he began experiencing the same problem. It turns out that the screen goes to sleep but what’s odd is that the power lights and the keyboard are still working. The computer is also warm to touch which shouldn’t be the case when it is in sleep mode. And when some users tried checking the event log, it showed them that the computer didn’t actually go into sleep mode but it shut down instead. To fix this issue, here are some possible fixes that could hopefully work.

Option 1 – Edit the Power Plan settings using Control Panel

• Click the Cortana button and type “control panel” in the field and select the appropriate result to open Control Panel.

• Now tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
• Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:

PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage Microsoft.<YOUR APP ID HERE>).InstallLocation + 'AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"

• Wait for the process to be completed and then restart your computer.

Windows comes with a built-in backup solution. However, if it failed because of an internal error, you will encounter an error message saying, “The backup application could not start due to an internal error, Server execution failed (0x80080005)”. When you get this kind of error, it means that it did not start and the process failed with a Server execution error. If you got this kind of error worries not for this post will guide you in fixing the problem in your Windows 10 computer. The Windows Backup service is an excellent feature in Windows that only works on the NTFS file system and if you want to use this make sure that you have formatted your files system to NTFS. It is performed by the Volume Shadow Copy, all you have to do is right-click on any folder and if you see the “Previous versions” option, this means that a backup process runs from time to time and can bring back old files when needed. To resolve the “The backup application could not start due to an internal error”, here are two suggestions you can check out.

Option 1 – Check if the Volume Shadow Copy service is running and restart it

The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:

• Click on Start and type “cmd” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
• Next, type the “net start sdrsvc” command and hit Enter to start the service again.

Note: You can also restart the service using the Windows Services Manager.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
• From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
• Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.

Option 2 – Try to run the Volume Shadow Copy Service in a Clean Boot State

If the first option didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run Windows Backup again.

• 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 Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to run the Volume Shadow Copy service again and see if the process goes smoothly.

Note: You might also want to delete all the files in the backup solution if you want to start fresh with the backup solution. Just go to C:/System/Volume/Information/Windows Backup and take ownership of the folder. After that, make sure to stop the Volume Shadow Copy service and then delete all the files inside it.
