Fixing the No Audio Output Device is Installed

A lot of Windows users, use a second GPU for their computer systems, especially gamers above the dedicated graphics card. The operating system is set such that the dedicated high-end graphics card is set to default but there are times when the system does not recognize or detect the second graphics card. Even though every computer system comes with an integrated graphics card, for the most part, it is insufficient for graphics-intensive games and software which is why if you have an extra dedicated graphics card and your computer does not seem to detect or recognize it, then this post is for you. It could be that the dedicated graphics card has failed or it could also be an issue with the drivers and so on. Follow the suggested options below to resolve the problem.

Option 1 – Update your Graphics drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 2 – Update the BIOS

Take note that you have to be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 3 – Try changing the GPU settings

• Right-click on any empty space on your Desktop and select Graphics Properties. Note that the Graphics Properties screen depends on the graphics drivers installed on your computer and are system-specific as they may be different for other systems but they aren’t hard to find.
• After that, make sure that the dedicated Graphics card is selected as Default under the Select Display drop-down.
• If the Graphics card isn’t set as Default, set it and click Apply and Exit.

Option 4 – Try disabling the driver for the integrated Graphics card

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, expand the list of Display Adapters and then right-click and select Disable device for the Integrated Graphics card. However, if the dedicated Graphics card fails, the display won’t work so you need to restart the system and enable it.

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

Option 3 – Bypass the Certificate Revocation Check

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

• In the search box of your browser, type “internet options” and open it once it appears.
• After that, go to the Advanced tab and navigate to the Security subheading.
• Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
• Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

About Browser Hijackers

Browser hijacking is a type of unwanted software, commonly a browser add-on or extension, which then causes modifications in the web browser’s settings. Browser hijackers can do more than simply modifying home pages. It redirects you to the sponsored sites and inserts advertisements on the internet browser that helps its creator generate earnings. A lot of people think that these types of sites are legitimate and harmless but that is not true. Nearly all browser hijackers pose an existent threat to your online safety and it is vital to classify them under privacy dangers. In a much worst case, your web browser could be hijacked to download malicious software that will do a lot of damage to your computer.

Indications of browser hijack

There are many symptoms that point to a browser hijacking: you see unauthorized modifications to your web browser’s homepage; you get re-directed to sites you never intended to visit; default web engine is modified; you’re getting browser toolbars you haven’t noticed before; your internet browser will display constant pop-up windows; your web browser starts running slowly or presents frequent errors; You can’t access certain websites, particularly anti-virus websites.

How they get into your computer or laptop

Browser hijackers infect computers via malicious email attachments, downloaded infected computer files, or by visiting infected sites. Many web browser hijackings originate from add-on software, i.e., browser helper objects (BHO), toolbars, or extensions added to web browsers to give them extra features. Browser hijackers sneak to your computer along with free software application downloads that you unknowingly install alongside the original. An example of some well-known browser hijacker includes Conduit, Anyprotect, Babylon, SweetPage, DefaultTab, RocketTab, and Delta Search, but the names are regularly changing.

Removal

Certain browser hijacking could be quite easily stopped by finding and removing the corresponding malware application from your control panel. But, the majority of hijackers are really tenacious and require specialized applications to remove them. You should think about undertaking manual repairs only if you’re a tech-savvy individual, as potential risks are associated with fiddling with the system registry and HOSTS file. You might opt for automatic browser hijacker removal methods by simply installing and running a reliable anti-malware application. One of the top tools for correcting browser hijacker malware is SafeBytes Anti-Malware. It can help you remove any pre-existing malware in your computer and gives you real-time monitoring and protection from the latest internet threats. Together with the anti-malware tool, a system optimizer will help you in removing all linked files and modifications in the computer registry automatically.

What To Do When You Cannot Install Any Antivirus?

All malware is inherently dangerous, but certain kinds of malware do a lot more damage to your computer than others. Some malware variants modify internet browser settings by including a proxy server or change the computer’s DNS configurations. In such cases, you’ll be unable to visit some or all websites, and thus unable to download or install the required security software to clear out the computer virus. If you are reading this, you may have infected by a virus that prevents you from downloading computer security software like Safebytes Anti-Malware. Although this sort of issue will be difficult to circumvent, there are some steps you can take.

Make use of Safe Mode to resolve the problem

If the malicious software is set to load immediately when the computer starts, switching into this mode may well prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the computer is starting up or run MSCONFIG and locate the “Safe Boot” options under the “Boot” tab. Once you are in safe mode, you can try to download and install your anti-malware software program without the hindrance of malicious software. After installation, run the malware scanner to eliminate most standard infections.

Switch to some other browser

Malicious code may exploit vulnerabilities on a specific internet browser and block access to all anti-virus software websites. When you suspect that your Internet Explorer happens to be hijacked by a computer virus or otherwise compromised by hackers, the best plan of action is to switch to a different internet browser such as Google Chrome, Mozilla Firefox, or Apple Safari to download your chosen security application – Safebytes Anti-Malware.

Install and run anti-virus from your Thumb drive

Another solution is to save and run an antivirus program entirely from a USB drive. Try these simple actions to clear up your infected PC using a portable antivirus. 1) Make use of another virus-free PC to download Safebytes Anti-Malware. 2) Plug the Flash drive into the clean computer. 3) Double-click the Setup icon of the antivirus software to run the Installation Wizard. 4) Select the drive letter of the flash drive as the location when the wizard asks you where you would like to install the anti-virus. Follow the on-screen instructions to finish the installation process. 5) Remove the pen drive. You may now use this portable anti-malware on the infected computer. 6) Double click the Safebytes Anti-malware icon on the flash drive to run the program. 7) Run Full System Scan to identify and get rid of all kinds of malware.

Technical Details and Manual Removal (Advanced Users)

If you don’t want to use malware removal software and prefer to eliminate Sadooma manually, you could do so by going to the Add/Remove Programs menu in the Control Panel and removing the offending software; in cases of browser add-ons, you may uninstall it by visiting the browser’s Add-on/Extension manager. You might even want to reset your browser settings, as well as clear your web browser cache and cookies. In order to ensure the complete removal, manually examine your hard disk and registry for all the following and eliminate or reset the values as needed. However, editing the Windows registry is actually a complicated job that only advanced users and professionals should try to fix it. In addition, certain malicious programs have the capability to defend against its deletion. You are encouraged to do this procedure in Safe Mode.

You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

• First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
• Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
• After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.

Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
• From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
  • “This policy setting disables the acrylic blur effect on the logon background image.”
  • “If you enable this policy, the logon background image shows without blur.”

• Now click on OK and then check the login screen.

Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

If you are trying to run Windows Update but encountered an Error 0x80070003, read on as this post will guide you on how you can fix it. This kind of error in Windows Update can occur when you activate Windows Firewall or download from the Windows Store. This kind of error indicates that the Windows Update service or WUAUSERV is not started or that the Background Intelligent Transfer Service or BITS can’t be started. Aside from that, you can also encounter this error with the other Windows Update components. To fix the Windows Update error 0x80070003, you can try to run the built-in Windows Update troubleshooter or replace the old Configuration file named “Spupdsvc.exe”. You can also try to reset the Windows Update components or check the status of all the Windows Update-related services, as well as run a System File Checker scan.

Option 1 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error code 0x80070003. To run this troubleshooter, Refer to these steps:

• Tap the Win + I keys to open Settings.
• From there, click Update and Security and go to the Troubleshoot section.
• Next, select Windows Update and click the “Run the troubleshooter” button and wait until it’s finished, and then try to run Windows Update again.

Option 2 – Try replacing the old Configuration file named “Spupdsvc.exe”

The next thing you can do to fix the Windows Update error is to replace the Spupdsvc.exe file. This is a process file that comes under the Microsoft Update RunOnce service. So when an update becomes available for your computer, the process responsible for performing the upgrade is notified. In addition, the RunOnce entry is also added to the registry for the spupdsvc.exe and this process is executed when your computer restarts and when you log on.

• In the Start Search, type “command prompt” and from the search results, right-click on Command Prompt and select the “Run as administrator” option.
• Next, execute this command to replace the old configuration of the Spupdsvc.exe file with a new one: c m d (remove spaces on CMD) /c ren %systemroot%System32Spupdsvc.exe Spupdsvc.old
• After that, try to run Windows Updates again and check if the error is now gone.

Option 3 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• 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 wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go 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.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer.

Option 4 – Check the status of some Windows Update Services

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Windows Update – Manual (Triggered)
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Services – Automatic
  • Workstation Service – Automatic
• After that, check if the Service status of the listed services above are set to Running. If they’re not, click on the Start button to start these services and then check if the Windows Update error 0x80070003 is now fixed or not.

Option 5 – Run the System File Checker Scan

If manually resetting the Windows Update components didn’t work, you can run a System File Checker scan instead. It is a built-in command-line utility that replaces bad and corrupted system files with good system files that might be the cause why you’re getting the error when you try updating your computer. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

About Potentially Unwanted Applications

Have you ever found an unwanted program on your computer system and pondered how it got there since you are sure you didn’t purposefully download and never gave authorization to be installed? A PUA / PUP (potentially unwanted application / potentially unwanted program) is a piece of software that comes bundled with freeware/shareware and you agree to install on your computer. These are programs you definitely don’t want on your PC since it doesn’t give any beneficial service. The term PUP was first coined to outline this downloadable crapware as something other than malicious software. The reason is, most PUPs get into a PC not because they slip via the security holes, for instance, but because the users have installed them by themselves – 100 % unintentionally needless to say. PUPs might not be malware but nevertheless, they are dangerous programs for your laptop or computer. At best, these types of unwanted programs provide hardly any benefit, and at worst, they can be quite harmful to your computer.

What do PUPs do on your PC, precisely?

Most Potentially Unwanted Programs comes in the form of adware, which typically aims to exhibit lots of annoying pop-up ads, banners, coupons, and bargains on web pages you explore.

They could appear innocent but PUPs tend to be spyware. And in the large majority of the cases, end-users will not be aware that they’re installing an unwanted program. These are software programs that don’t do anything useful to you; in addition to taking up space on your hard disk drive, they will also slow down your computer, often modify settings without your permission, and the list of frustrating features goes on and on.

How can you avoid ‘crapware’

• Read the fine print so that the end-user license agreement (EULA) you’re accepting is only for the program you actually intend to download. • Always choose “Custom” or “Advanced” installation and never blindly click the Next button, which should let you uncheck any “foistware” software programs you do not want. • Have a solid anti-virus program such as Safebytes Anti-malware that can protect your computer from PUPs. As soon as you install this software, protection from malware and PUPs is already turned on. • Avoid installing a freeware application you will not use. Nowadays ‘freeware’ isn’t actually freeware – but “crapware” bundling nonsense. • Don’t download software programs from pop-ups, online advertisements, file sharing websites, as well as other unreliable sources; look out for any preset, unwanted options when downloading the program. Avoid visiting blogs and sites that support pirated programs.
