Computer crashes are one of the most annoying things that can happen to users. It often loses your data and work, you must spend extra time if you were in the middle of something and can even break Windows itself. Before we move to the article I just want to say that technically there are no random crashes, there is always a reason why the system hangs up, why you received blue screen, annoying restarts out of nowhere and many more PC crashes. In this article, we will explore many possible reasons why something may occur and offer you straight forward solution on how to escape the situation and prevent it from happening again. Without further delay, let's begin:

1. Check switch connectors and power outlets

   Yes, sometimes the most basic approach provides the best results, check to see if your power outlet is stable and providing you with constant voltage, if not, maybe you want to invest in a UPS system so you do not face random shutdowns and restarts during work, also while you are at it, check to see if that reset and power switch are connected properly and that they are not dirty or loose.

2. Clean your PC and check connectors

   Dirt can cause many issues with computers, from overheating to shutdowns to blue screens and memory dumps, check to see if your computer is clean enough and that all connectors are connected tight into their respective sockets.

3. Check the temperature of your CPU

   CPU overheating can cause so-called random freezes and blue screens, the computer might shut down or restart also without any visible reason. Check to see if your fan on the CPU is working properly and change the thermal paste if needed.

4. Check the health of your hard drive

   If your hard drive is beginning to go down the path of dying out, many issues can come from this condition. There are many tools on the internet and in Windows itself to check if your hard drive is working properly.

5. Run antivirus and firewall

   Random lock-ups or similar issues can also occur if by any chance you have some malware on your system, run protection software, and keep it updated to make sure the issue does not come from the computer being infected with malicious applications.

6. Keep system clean

   Have a habit to clean regularly system files and registries, keep removing unnecessary files from your computer and regularly update your Windows and applications along with drivers.

7. Run memory test

   Bad RAM bank can cause many issues during the work, check it out to be sure the problem is not RAM itself.

8. Do not run applications that are too demanding for your system

   Some applications require stronger hardware, and some require the latest hardware, if your computer is a little outdated, running a demanding application can cause issues like freezing, restarts, etc.

9. Remove applications you do not use

   This does not seem like anything important but if you are not using a specific application just remove it from the system, why? Sometimes an application has some ties to certain services and if it is outdated can cause issues for newer ones.

10. Stop installing everything you find on the internet

    Yes, that extension for chrome looks cool, yes, that fancy new player seems sick but if it is from an unverified source and from the unknown publisher without any reviews maybe you are better off with it. You can never tell what you might be placing into your system from the internet.

And that's it, 10 reasons and solutions on what to do on random computer freezes, crashes, etc.

As you know, Microsoft Edge is the default web browser in Windows 10 operating system. It is a built-in browser that replaced the ancient Internet Explorer for its performance and features. Aside from being the default web browser, it is also set as a default PDF viewer in Windows 10. So if you open a PDF file, it will be automatically opened in the Edge browser even if you have installed a PDF reader on your computer. However, some users recently reported getting an error that says, “Couldn’t open PDF in Edge, Something’s keeping this PDF from the opening” when they tried to open a PDF file or view an internet link that has a downloadable PDF file in the Edge browser.

When Microsoft held Windows 11 presentation it took special time to present the upcoming new Windows 11 store as kind of a big deal. It was openly stated that with new Windows we will get a new store with a different attitude and new look.

New Microsoft store

Microsoft has stated that both customer and developer feedback over time has contributed to their redesign and rethinking of the store itself. They want to be sure that policies for developers are more straightforward and clear so more developers will decide to bring their product to Windows. As for customers, they want more safety and more security so they feel protected when making a purchase. The new store will come in Windows 11 but also in Windows 10 as well via update.

Stories and collections

Introducing the new store will be curated stories. Microsoft believes that stores should be focused on user experience so stories from customers themselves will play a big role here. They are rich editorial content to keep you informed about the best apps and inspire you to achieve more with your device. This approach to information is aimed at bringing unknown applications to users via presenting them in a professional manner. Android apps in the store As stated in Windows 11 unveiling and presentation, Android apps will work inside Windows 11. Microsoft has teamed up with Amazon to bring you Android apps directly inside Windows via the new Microsoft store.

Pop up store from within a browser

When you are surfing on a certain webpage and want to save and install the application from there, a new pop-up store window will show allowing you to install the app directly. Microsoft has not said will this feature work outside their Edge browser so we will have to wait and see about that.

Support for multiple types of applications

Since now developers were tied to certain formats if they wanted to publish their application in any kind of environment. Microsoft wants to bridge this. Windows developers can publish any kind of app, regardless of app framework and packaging technology – such as Win32, .NET, UWP, Xamarin, Electron, React Native, Java, and even Progressive Web Apps. For Progressive Web Apps Microsoft has made open-source tool PWABuilder 3.

Flexibility and choice of commerce platform

Starting July 28, app developers will also have an option to bring their own or a third-party commerce platform in their apps, and if they do so they don’t need to pay Microsoft any fee. They can keep 100% of their revenue.

If you have been using Windows for quite some time now then you’re probably aware of the BIOS or UEFI password. This password lock is the one that ensures you enter the set password even before your Windows PC boots up. However, there’s just one downside with the BIOS or UEFI password – there is no recovery option, unlike your Microsoft account. Worry not though for this post will guide you on how you can set or recover a BIOS or UEFI password on your Windows computer. The BIOS or UEFI passwords are stored at the hardware level which means that unless the OEM wants or has configured a way to recover the password, it is pretty much impossible to reset it. There are times when they are so strict that the only way to get through it by contacting customer care. Note that any Windows computer with this lock can’t be unlocked by trying to reinstall Windows. In this post, you’re going to have to remove the CMOS battery temporarily, clear unknown BIOS/UEFI passwords using the bios-PW website as well as call customer care. For more details, refer to the options provided below.

Option 1 – Remove the CMOS battery temporarily

In case you didn’t know, every motherboard comes with a CMOS battery which helps the computer system to keep the clock ticking and in making sure that the BIOS settings are not lost when the computer is powered down. Every time a computer is turned on, the CMOS battery ensures that the information is available for the computer to boot up. So when you remove the CMOS battery temporarily, say about 30 seconds or a minute, the settings will be lost. There are some motherboards that are built-in ways that when you remove the battery for long, it will reset everything including the password for the BIOS or UEFI.

Option 2 – Clear the unknown BIOS or UEFI passwords using a bios-PW website

If the first option didn’t work, you can try using this BIOS Password website at http://bios-pw.org/ to clear the password.

• When prompted by the BIOS, enter the wrong password a couple of times as doing so will lock you out of the system.
• After that, you will see a new number or code on the screen which will include a message about System Disabled [XXXXX] Service TAG [YYYYY].
• Next, open the BIOS Password website and enter the XXXXX code in it and make sure to tap the Shift + Enter keys or just enter.
• Now it will open multiple unlock keys which you can use to clear out the BIOS or UEFI lock on your Windows PC.

Option 3 – Call the customer care

If the second option still didn’t work, you have to call customer care and follow their suggestions for they will walk you through fixing the problem using the service tag or might suggest that you visit a service center to make things easier for you. Note: You also have the option to set a BIOS or UEFI password. Although it isn’t recommended, you still can do it if you really want to. Remember that the BIOS or UEFI interface varies from OEM to OEM so you must find something related to either PASSWORD or SECURITY. You will have the following similar options:

• Supervisor password – it’s the same as the master password that can change important system settings.
• User password – with this password, any user can change minor settings.
• Master password – you can use this password for a hard drive or as a general password.

There are several OEMs that offer micro-control where you have to enter the BIOS password. For instance, you’ll have the option to skip for a normal restart, or when you select a boot device while you might have to enter the password for unattended reboots or when your PC is powered on, etc. And if you are here to remove the password, you need to find a remove password option in the same section. You will be prompted to enter the set password once and if it’s correct, it will remove the BIOS password. After that, you have to save and exit the BIOS then restart your computer and check if the settings are properly applied.
