HDMI Port not working properly in a Windows PC

Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:

• a memory location that was referenced
• IRQL at time of reference
• 0 = read, 1 = write
• code addressed which referenced memory

As mentioned earlier, if you are an end-user, there is nothing much that you can do to resolve this problem, but worry not for there are still possible solutions that could help you in fixing it. Refer to the suggestions laid out below to fix Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL error.

Option 1 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

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.

The new Windows 10 update has brought some fixes, improvements, and little things to personalize our computer more.

In order to change and personalize your START menu and/or title bars all you have to do is click on your windows icon to bring the start menu up and then click on settings. Once you are in setting windows go to personalization settings. When the personalization setting opens go-to color tab on left and scroll down until you find 2 checkboxes under "show accent color on the following surfaces:" check ones you wish to apply the effect to and you are done. Now your START menu and/or title bars are using the color scheme of your choice.

Gaming Wonderland is a Browser Extension for Google Chrome developed by Mindspark. This extension allows you to look up some popular browser games, as well as to find multiplayer games. When installed it changes your default search provider and your default home page to MyWebSearch. While browsing the internet, this extension will gather your browsing information, website visits, clicks, and other information that is later sent to Mindspark ad servers and used to better target ads.

While using this extension you will see additional unwanted ads appearing throughout your browser sessions.

Due to the nature of this application and the fact that it has been marked as a Browser Hijacker by several anti-virus scanners, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking means that a malicious code has power over and modified the settings of your internet browser, without your consent. They are made to disrupt browser functions for a variety of reasons. These are generally used to force visitors to a specific site, manipulating web traffic to generate ad revenue. It may appear harmless, but the majority of such sites are not legitimate and will present a serious risk to your online safety. As soon as the program attacks your computer or laptop, it begins to mess things up a whole that slows your system down to a crawl. In the worse case, you could be pushed to tackle serious malware threats as well.

Browser hijacking symptoms

When your web browser is hijacked, the following could happen: you find unauthorized modifications to your web browser’s home-page; new bookmarks pointing to pornographic websites have been added to your bookmarks; default web engine is changed; you are finding browser toolbars you haven’t noticed before; unstoppable flurries of popup advertisements show up on your PC screen; your browser gets slow, buggy, crashes quite often; you’re prohibited access to specific websites, including the site of an anti-malware software firm like SafeBytes.

How does a browser hijacker infect a PC

Browser hijackers might use drive-by downloads or file-sharing websites or even an e-mail attachment in order to reach a targeted computer. They could also be deployed through the installation of a web browser toolbar, add-on, or extension. A browser hijacker can also be installed as a part of freeware, shareware, demoware, and pirated programs. A good example of a notorious browser hijacker is the latest Chinese malicious software called “Fireball”, which has attacked 250 million PCs worldwide. It works as a hijacker but can be turned into a fully functioning malware downloader later on. Browser hijackers will affect the user’s browsing experience severely, keep track of the websites visited by users and steal private information, cause problems in connecting to the net, and eventually create stability issues, making applications and computers freeze.

Browser Hijacker Malware – Removal

Some kinds of browser hijackers can be removed from your computer by deleting malicious software applications or any other recently added shareware. At times, it can be a tough task to discover and get rid of the malicious component since the associated file might be running as part of the operating system process. Novice PC users should not try for the manual form of removal, since it calls for thorough computer knowledge to do fixes on the system registry and HOSTS file. Installing and running antivirus applications on the affected system will automatically erase browser hijackers and also other unwanted applications. Safebytes Anti-Malware incorporates a cutting-edge anti-malware engine that will help you prevent browser hijacker infection in the first place, and clean up any existing problems. Use a system optimizer together with your antivirus software to fix various registry problems, remove system vulnerabilities, and boost your computer's overall performance.

If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
2. An issue with system maintenance could cause the problem.
3. Malware or some other software might have created an undetectable hidden file.
4. Space could be occupied by the trashbin folder.
5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
6. Run ChkDsk
7. Clear all Junk files
8. Reduce the space occupied by the system restore points
9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:

• In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
• Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
• After that, click on the System Maintenance troubleshooter to run it.
• Once the process is completed, restart your computer.

Microsoft Edge may be about to win a lot of fans by introducing a new feature that it says could prevent one of the most annoying things about being online. A new update to the browser suggests it is looking at a way to block auto-playing videos by default when a user navigates to a website. People spotted a new entry to the Microsoft Edge Canary browser where the company tries out its in-progress updates, that suggests auto-playing videos may have had their day at last. The new addition, for Mac, Windows, and Linux systems, is called “Autoplay Limit Default Setting”, with the description suggesting that Microsoft Edge would set the media autoplay setting to "Limit" as a default - stopping videos from starting up when a user lands on a website. Currently, Edge offers two options for users to control media autoplay - "Allow" (the current default setting), where all videos on a website will play automatically with sound, and "Limit", where media won’t be autoplayed on sites that a user has previously visited. It appears that Microsoft is looking to test the feature in Canary before rolling it out to a wider user base - as blocking autoplaying videos can cause issues for some websites. The same Canary entry also hints at a future "Block" option, which would presumably stop any videos or media from playing when a user lands on a website. However, this feature, which is also listed as being available for Mac, Windows, and Linux systems, doesn't appear to be enabled as yet.

What is RTX

Nvidia GeForce RTX is a high-end professional visual computing platform created by Nvidia, primarily used for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production. Nvidia RTX enables real-time ray tracing. Historically, ray tracing had been reserved for non-real-time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows, and reflections. RTX runs on Nvidia Volta-, Turing- and Ampere-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.

Advantage in games

With incredible lighting and shadows, reflection, better smoke, and water effects, and more, RTX has managed to place awesome real-time effects on your desktop all that’s to Nvidia technology behind it. Of course, in order to harvest this kind of technology and features game itself needs to support and have RTX in it, you can not turn RTX in just any game, the game itself must have technology build in it.
