If your WIFI signal is strong but you can not connect to the internet then keep reading in order to find out why this happens and what can you do to fix it. One very important thing to know and understand is that WIFI and the internet are two different things and that they altho connected and working together are basically 2 things. WIFI is a name for a group of technologies that are using radio vawes to connect to the router in order to access the internet. The Internet itself is series of computers all connected in LAN. Think of WIFI like some invisible cable that connects your computer to the router. When we put things into perspective this way it becomes clear that we can indeed have a strong WIFI signal and that we are connected to the router but the router itself is not connected to the internet. So basically troubleshooting an internet connection is troubleshooting the router itself. The most common approach is to reset the router, turn it off, then back on, check cables, etc. But be sure that if your WIFI signal is strong and you can not access the internet it is a router issue.

What exactly is no audio device malfunction?

No audio device error is among the malfunctions that many Computer consumers run into. No sound or audio can be heard from the computer when the error occurs.

Solution

Error Causes

There are numerous elements that may be the basis of this malfunction. Corrupted or broken sound card drivers, incorrect Device Manager Options for example, or even incorrect BIOS configurations.

Further Information and Manual Repair

How could you recover the standard production of audio by your personal computer and solve this malfunction? Like a number of additional malfunctions, the method of the repair depends on its trigger. To properly solve this dilemma, you are required to run through an evaluation of the pc system so that you can pinpoint the cause. This is because there are numerous variables, which alone, or concurrently may trigger this dilemma. These measures will allow you to work out the no sound device error in your personal computer programs, identify the trigger and fix it. Follow the directions in step 1 if your computer has an onboard audio device installed in it and assess the BIOS settings. You can jump step 1 and move to step two if you utilize a separate sound card.

STEP #1 - Assess the BIOS options.

No sound device error can be caused by incorrect BIOS configurations in your Personal Computer. By fixing these settings if they are the cause of the malfunction, you can easily solve it. Make Sure you restart the pc and immediately access the BIOS options. By locating the Sound card, which is usually known as the AC97 Audio, you should subsequently open the Integrated Peripherals. As soon as you locate it, set it to Allow or Auto. Finally, you should access the On-Board Audio AC97 Control and set it to Allow or Auto as well. If it doesn't solve the situation, proceed to Step Two.

STEP #2 - Analyze the Device Manager

No sound device malfunction can be additionally caused by malfunctions with the Device Manager. To solve this issue, go to My Computer, right-click it, select properties, click on the Hardware tab, then click on Device Manager. At this windowpane, analyze the movie, audio, and game controllers. If you learn that there is a cross on any of the sub things, right-click it subsequently and set it to Enable. The sound card driver may have not been correctly installed or may be damaged if there is Exclamatory Mark or Question Mark on the device manager menu. This does not mean that the sound card driver is ok. It may have malfunctioned even though you do not locate anything unusual. This is because the Device Manager doesn't always recognize errors in audio hardware. After this, you can proceed to step 3.

STEP #3 - Upgrade or reinstall the Sound Card Driver.

About 80% of "no sound system discovered/installed" malfunctions come from broken and/ or out-of-date card drivers. The sound card will not be detected by the Windows Operating System, when the audio card driver is corrupted, damaged, or out-of-date and therefore no sound will be produced by your computer. If this is the cause of the no sound device malfunction, you should reinstall the Audio Card Driver on your computer. Still, you can utilize driver upgrade applications on the web that will help you upgrade out-of-date drivers.

There are instances when there are multiple accounts which is the result when there are a lot of users who use the computer. Some may use it more often, while others may seldom use it. Having multiple accounts can be quite confusing and inconvenient especially if it takes a lot of space. Thus, in this post, you will be guided on how you can delete a User Account on your Windows 10 computer, as well as how you can create a backup of the existing profile data and files. All the data of user accounts can be found at C:/Users, where its folder name will be exactly the same as the name of the user. You can check the exact user’s name by simply using the “net user” command either via Command Prompt or Windows PowerShell. Once you delete a user account, its folder, along with its files, will also be deleted. You can also create a backup for user files and the best way to do that is by copying the folder to other partitions or to an external drive. Here are two methods you can check out to delete a user account in Windows 10 – you can do it via Windows Account settings or via the command line. For more details, follow each one of the options provided below.

Option 1 – Delete the user account using Windows Account settings

• First, go to Settings > Accounts > Family & other users.
• Next, select the account you want to delete and click on the Remove button. This will open a confirmation window along with a warning message and two buttons that say, “Delete account & data” and “Cancel”.
• Click on the Delete account & data button to delete the user account.

Note: Once you remove a user account, it will also remove all its corresponding data such as items like Documents, Photos, Music, Desktop, and other related folders. Thus, if you have not created a backup, then you won’t be able to recover those files.

Option 2 – Delete the user account using the command line

If you want to delete several user accounts, then doing it via Command Prompt or Windows PowerShell is a lot quicker. To get started, follow these steps:

• In the Start Search, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• Next, type the “net user” command and hit Enter to execute it. This will show you the exact usernames on the computer.
• After that, type the “net user <username> /delete” command and hit Enter to execute it. This will delete the account and all of its data without any warning. You have to replace “<username>” with the name of the user account.

If you are trying to save a file in a PDF format on your Windows 10 computer but then the PDF text content in an Adobe file suddenly disappears, then read on. This post will give you more insight into this issue. This kind of issue is rare and mostly occurs in forms that you can fill upon. In such a case, the text you enter in the form vanishes right after you click the Save button. One of the benefits of working with PDF files is that it has the ability to compress high-quality files to relatively small file sizes. This is really useful especially when you are saving hard drive space and you’re working with limited storage resources. However, these files can contain layered content if they are created from layered documents using applications like Adobe InDesign. Consequently, a single page of the PDF file can contain different layers with different content. So if you try to save or print a PDF file that contains layered content, the elements will disappear from the PDF. To resolve this issue, you can try to merge or flatten the file since it will help keep the changes in the PDF file. On the other hand, you can no longer make any alterations or form data once you flatten the file. Another thing to keep in mind is that merging or flattening the file can’t be undone so you might want to save another copy of the file before you proceed.

Option 1 – Print to PDF

• First, you have to open the desired PDF file and tap the Ctrl + P keys to open the Print dialog box.
• After that, select the “Microsoft Print to PDF” option as the printer.
• Once the action is confirmed, it will regenerate another version of the PDF file with the default settings and merge all the existing layers into a single layer.
• On the other hand, you can also click on the “File” menu of the PDF file and select Print.
• From there, click on the Print button and select “PostScript (*.ps)” as the “Save as” type to save a PostScript copy of the original PDF file.
• Once you’re done, double click on the .ps file to open the file in the Adobe Distiller which will flatten the file automatically and convert it to a PDF file with only one visible layer.

Option 2 – Save the PDF file as an Optimized PDF file

If you are using the Acrobat Reader Pro version such as the Acrobat Pro, Foxit, and so on, you can try to flatten the layers by saving the PDF file as an Optimized PDF file. Refer to these steps to do so:

• Select File > Save as > Optimized PDF.
• Next, select the Transparency checkbox from the Settings window that opens.
• Then click on the Save button to apply and save the changes made. After that, the PDF text content should not disappear when you try to save a file on your Windows 10 computer.

Error Code 0xC004C020 (Code 0xC004C020) – What is it?

Error code 0xC004C020 (Code 0xC004C020) is an error that occurs when you attempt to activate a copy of Windows 7 with a key, but the key has already been activated multiple times. When receiving this error code, it means that you are trying to exceed the number of times that the Windows 7 key is allowed to be activated. Common symptoms include:

• Attempting to install Windows 7 with a key and a dialog box with the code 0xC004C020 is displayed.
• The computer is unable to install Windows 7 with the key.
• Certain features will refrain from working until the correct key has been entered.

Solution

Error Causes

Error Code 0xC004C020 occurs when you are not able to install Windows 7 using a previously purchased key code that has been installed numerous times previously on the same computer.

• You are not able to use your previously used key to install Windows 7.
• You have used the Windows 7 key the maximum number of times allowed.

Error code 0xC004C020 simply means that the Windows 7 code that you are trying to use to install Windows 7 has already been used the maximum number of times allowed, even when installing it on the same computer that it was previously used on. This would indicate that the key is what is known as a volume key- meaning that there is a cap on the number of uses.

Further Information and Manual Repair

Many people encounter this problem when they are doing software development or testing and need to reinstall Windows 7. Some people might also encounter this error code when installing Windows 7 with a key that was used too many times previously. It should be noted that there are several ways to fix this problem, but if nothing is working, you should contact a computer repair technician.

Method One

Activate by phone- the long method.

1. Click the start button, right-click Computer, click Properties, and then click Activate Windows.  This will open Windows Activation.
2. Click on “Show me other ways to activate”.
3. Find and enter the Windows 7 key, then click Next.
4. Click on “Use the automated phone system”. If you are prompted for an administrator password or a confirmation, confirm or type the password now.
5. Select the location nearest to you and then click the Next button.
6. There will be a list of available phone numbers, choose one and call it. There will be an automated system that will guide the activation process.
7. Enter the installation ID when prompted, it will be listed on your computer screen.
8. The phone system will give you a confirmation ID, write this down.
9. Type this confirmation ID into the space that is provided by step 3. This will be in the activation dialogue. Then, click NEXT and follow the instruction.
10. If this is not successful, stay on the line and be transferred to a customer service representative that will assist you.

Method Two

Activate by phone- this is a much simpler method.

1. Click on Start, type: slui.exe 4 into the Search box
2. Press Enter on the keyboard.
3. Pick your country.
4. Choose the Phone Activation option; stay on hold to speak with a customer service representative.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Blackouts are one of the most annoying things that can happen in the modern age. We have all learned to depend on electricity, maybe too much, so having a backup plan in these unpleasant situations is necessary. Here are some good gadgets for these kinds of situations.

Power Bank

The fully charged power bank is a great item that could fill up your phone or tablet. If it is a larger power bank it could fill them up all the way to the top several times and having charged phone or tablet can help greatly with some fun during dark times. The power bank can also be used to fill up other gadgets on this list so if the power outage is expected to last longer perhaps it would be wiser not to waste it on phone/tablet games.

Portable Generator

If the power bank is too short-lived for your needs, a portable generator is always a good option since it can provide power for longer time periods. The solar generator is what we recommend because it is much cheaper to produce electricity but it is limited if a power surge comes at night, one on gasoline is more stable and practical but it costs more to produce electricity.

Portable Solar Charger

One more electric-producing device on the list, this one however is aimed at charging your phone, tablet, or laptop by harvesting Sun's energy and turning it into valuable electricity for your devices. Fully silent and easy to operate this is a great tool for power outrage. It will not be able to produce electricity for smaller house appliances but for basic phone/tablet/laptop needs it will suffice.

Panic light

Self-sustained with its own battery, panic lights are great assets for lightning when power is not present. They can turn automatically when the circuit detects that power is missing but can be also manually switched on or off. There are many versions of panic lights ranging from the light they produce to how long can they work so picking the right one will depend entirely on your home size and needs.

USB Headlamp

If you lack panic lights USB headlamp is a great choice to light your way and it works even better than a flashlight, although a flashlight is also a great tool, a headlight will provide you with free arms to do various things that you would not be able to by holding a flashlight. Modern headlights come with LED lights so they provide a good amount of light with small power consumption and they can be recharged in a power bank, solar charger, or generator.

LED lantern

LED Lantern is a gadget sitting somewhere between a headlight and a panic light, it offers around the same light amount as a panic light but you can carry it around with you. Of course, it will drain its battery faster than a panic light and it will still need to carry around but it can offer some good options when you need it, like taking it with you to the toilet.

Electric Lighter

An electric lighter is also one of the things that you will need, it can ignite candles, paper, stoves, etc. Its battery is usually enough for extensive use and there are small chances that it will need to be recharged. Having matches is also smart, just in case.

Solar Oven

Great gadget when outbreaks last long or when you get hungry. Not all households have gas ovens so a Solar oven is a great tool to keep you full of food. Granted it will not be on par in speed and quality with a regular oven but when it is the only option it will suffice.

Finally, some good news for Blizzard entertainment after tons of bad stuff happening around it regarding lawsuits and people layoffs. Diablo 2 has become the most-watched game on Twitch after its official release and sold copies are on a satisfactory level. For people not familiar with recent events, the state of California has sued Blizzard for various things including discrimination and offensive behavior. Later Blizzard executives were caught shredding some evidence and things just started to go to worse from there. After much drama, many people believed that this is the end for Blizzard entertainment and that they would not be able to recover from this since the community has sided with California and Blizzard has received a large punch as many subscribed WOW players have left the game. Things are not so grim as they were looking as their Diablo 2 remake has made moderate success despite being released in these troubling times and there are rumors of Overwatch 2 planned release date as of the first quarter of 2022.

Error Code 0xc004c008 - What is it?

This specific Windows 8.1 or Windows 10 error code has to do with the number of times you can use your license number to install windows programs on computers. All windows activation codes are licensed to be used one time for a device, to control piracy, but what happens when your PC crashes, or you have to change a hard drive component and are forced to re-install Windows Operating System. Luckily, there is an easy fix for this issue.

Solution

Error Causes

Basically, when you need to re-install the Windows operating system that you have previously bought and installed on another computer an error code will be displayed with a message telling you that the activation server determined that the specific key could not be used for activation. This occurs because the key has already been used on that computer, or a different one, to install operating systems. There are a few easy fixes for this issue, and most of them should be easily completed on your own.

Further Information and Manual Repair

There aren’t many explanatory ways to repair Error Code 0xc004c008. Below are two methods to go about addressing this issue.

Methods 1:

1. The first step is to open the “Run” Window. You can do this in two ways. First, press the “Window” key and press the “R” key simultaneously. This will open the “Run” menu. Or you can start the “run” window by going to the Start menu and selecting Run.
2. In the Run window type “SLUI 4” and click enter.
3. A Phone Activation window will open up, after which you'll need to select a few options.
4. First chose the country in which you registered the product for the first time.
5. Choose your country and a phone number will be displayed specific to your choice. You will now need to call the number provided.
6. After you’ve dialed you will be prompted to write your “Installation ID”. Type your “Installation ID” on the phone.
7. After that step, you will be asked how many copies of Windows have been installed using this license. Choose “1”, should anything else be chosen but “1”, this will not work.
8. After the process is completed, you will be given a confirmation ID and should be able to proceed as normal with installation. You will have a workable product key again.
9. Install whatever copy of the Windows Operating System you are attempting to with the new product key.

Method 2:

If the first method did not work, the only other option is to call Microsoft and walk through the process with a technician. To do this, dial “1-800-936-5700”. Explain the error that you received and the steps in the update process during which it was displayed. The technician will be able to walk through the steps from getting a new product key to finishing the installation.
