What Happens When Your PC reboots Randomly

A computer shutting down or restarting can be caused by a variety of factors. The three most common are a faulty power supply, a bad motherboard, or a laptop that overheats.

Remember, If it’s merely shutting off, it’s most likely due to overheating.

Your power supply may run out at any time. All of your hardware components are powered by the electrical supply. It can simply switch off if things aren’t going smoothly. Replacing them is quite cheap.

The worst-case scenario, which is sadly the most prevalent, is motherboard failure. Random shutdowns, restarts, and Windows problems may result as a result of this. At home, there is no practical method to inspect the motherboard. It is the most difficult element to repair when it breaks. Unfortunately, everything else is tied to it.

Incompatible or outdated drivers might sometimes be the source of the problem. This is especially if it began after a recent update or upgrade. The most common reason of unexpected restarts is your graphics card driver. As a result, remove the graphics card driver and allow Windows to obtain the most compatible drivers.

Is Your Device Not Turning On?

No matter how many times you push the power button to switch on your computer, no light appears and your monitor remains dark. This can be quite the conundrum for users, and confusing to say the least.

Here are a couple ways you may be able to remedy the situation:

First, double-check your power cable.

Check that it is correctly inserted and that there is power in the electrical socket where it is plugged in. Whether that works, you should grab a multimeter and check the power switch to see if it works as well. Remove all RAM and disconnect any devices linked to your PC.

If it still does not function and your power switch and power cord are both fine, test the power supply.

Clean it up

Clean the circuit board. Pay careful attention to the area surrounding the CPU, for any potential shorts, burn marks, and so on. Use a soft brush to dust off any kind of debris seen. If you find any burns on the motherboard, it needs to be replaced.

This is Why Your Computer Slows Over time

Everything seemed to run smooth and quickly when you first received your computer. However, it appears to be slowing down with time.

Why is this the case?

There are several variables to consider, the most important of which being that consumer hardware degrades with time. Parts wear out, heat damage occurs, and so forth.

Examine your motherboard for blown caps, dust, and other debris. Sometimes a simple cleaning may make a huge difference. If your caps are blown, it’s time for a new motherboard.

It could possibly be low on memory, too many programs opened, or even malware. Nobody chooses to have viruses on their computer. Unfortunately, this occurs frequently. Malware may significantly reduce computer performance.

Virus and threat protection may be found in the Windows Security section of the Settings app. This checks your computer and notifies you if any action is required.

Software and hard disk corruption are two factors that might cause your computer to slow down over time. Another major reason is a lack of RAM and simply running out of hard drive space. When you don’t have enough RAM, your hard drive tries to compensate for the shortage of memory.

Why is your MacBook’s Fans Running?

If you have a MacBook, you will want to read up on this.

Fun Fact: A MacBook Pro fan should always be available. It should not, however, be too loud or operate at a high pace all of the time. If it is at maximum RPM (typically about 6000 on a Macbook Pro), this suggests that there is software on your Mac that is straining the CPU or GPU.

Here are a few ways you can remedy this situation:

-Reboot your MacBook. If the fan is always spinning at full power, try restarting it.

-Remove Flash in your browser. Flash is currently disabled by default in Firefox. Flashcontrol is a Chrome extension that allows you to deactivate Flash instances (it still allows you to view Flash on a per-site basis as needed). This is one of the most common sources of CPU/GPU stress, and it will undoubtedly boost the fan speed because Flash is so demanding on hardware.

-Clear your browser history, and if you have multiple tabs open, close them.

Launch Activity Monitor to check which programs are consuming the most CPU power. You can also check which applications are consuming the most energy. Certain apps tend to cause the fans to speed up since the temperature of your CPU/GPU rises when you use them.

The Shake Feature on Windows OS

This handy feature is called Aero Shake.

If your display is cluttered with windows, remove the clutter by grasping the top of the window you want and “shaking” it on the screen to collapse all the others. You may use Aero Shake to reduce other windows on your PC by shaking the one you want to fixate on. Here’s how to turn it on, since by default, Aero Shake is turned off:

  1. Open Settings, and click on System.
  2. Click on Multitasking on the left.
  3. Turn On or Off Title bar window shake for what you want.

Just FYI: When you use Aero Shake to reduce all unnecessary windows, you lose access to the other windows. They will reappear on your screen after you utilize Aero Shake to bring them back into view. Want to bring them back? Shake it again, and the windows will return.

How to Control Background Apps

In Windows 10, certain apps have the ability to run in the background so you don’t have to worry about them. This feature was put into place by Microsoft to allow notifications and app updates to users. However, there’s a large downside: battery consumption and possible data drainage. Thankfully, there is a way to control your background apps, if you prefer.

Here’s how to get there:
  1. Go to Settings
  2. Click on Privacy
  3. Scroll down and click on Background apps

From here you can choose to turn on or off your option to allowing apps run in the background. Or, you can choose which apps you would rather not run in the background. This works well for those who need certain apps continuing to function.

Internet Explorer Being Used by Hackers

Microsoft has notified users that cybercriminals are taking advantage of a previously unknown zero-day vulnerability.

This is happening in Windows 10 as well as various Windows Server versions. The exploit might allow unscrupulous people to take control of PCs via compromised websites or malicious Office documents.

“Microsoft is investigating reports of a remote code execution vulnerability in MSHTML that affects Microsoft Windows. Microsoft is aware of targeted attacks that attempt to exploit this vulnerability by using specially-crafted Microsoft Office documents.

An attacker could craft a malicious ActiveX control to be used by a Microsoft Office document that hosts the browser rendering engine. The attacker would then have to convince the user to open the malicious document. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Microsoft Defender Antivirus and Microsoft Defender for Endpoint both provide detection and protections for the known vulnerability. Customers should keep antimalware products up to date. Customers who utilize automatic updates do not need to take additional action. Enterprise customers who manage updates should select the detection build 1.349.22.0 or newer and deploy it across their environments. Microsoft Defender for Endpoint alerts will be displayed as: “Suspicious Cpl File Execution”.

Upon completion of this investigation, Microsoft will take the appropriate action to help protect our customers. This may include providing a security update through our monthly release process or providing an out-of-cycle security update, depending on customer needs.”

Any fixes available?

How to Geek states on their website, “We could see an official fix for the exploit on September 14, 2021, when Microsoft is set to do its next “Patch Tuesday” update. In the meantime, you’ll need to be careful and disable the installation of ActiveX controls in Internet Explorer.”

How to Use Dictate on a Mac

Dictation, Apple’s fully featured accessibility tool, is simple to use. It also does a good job of interpreting your voice. And not everyone enjoys typing. Fortunately, Apple’s software allows you to say what you want to type instead of typing it.

“Do you want to enable dictation?”

To quickly enable Dictation on your Mac, head over to your System Preferences. Next, click Keyboard. Once there, click on the Dictation tab. You will be able to turn it on and select your language and a shortcut.

After you’ve enabled Dictation, begin speaking what you want to put in to see it appear on your screen. This also implies that you must dictate punctuation. Apple recommends dictating in small intervals of 40 seconds or less. You can talk far more quickly than your Mac can receive.

To stop dictating you can either click your shortcut button, click done under the microphone, or simply click return.

While your Mac is analyzing your dictated words, they show underlined. After you have finished dictating, the reformat themselves, as well as any words that your Mac has queried.

Things you need to know about Dictation

Dictation connects with Apple servers in order to transform your speech to text. As a result, it is never totally private. Dictation files can be saved and reviewed by Apple. They do this to enhance dictation, but you can turn it off in Security & Privacy of System Settings.

To utilize Dictation on a MacBook, you must have an active Internet connection. Apple uses linguistic data to analyze your speech on its servers. You will be unable to utilize Dictation if you do not have an internet connection.

Hope this helps make work or school a bit easier!

Will Windows 11 Be Better Overall?

While the major focus has been shown to be the overhaul of the taskbar, along with upgrading icons and adding functionality, there is more to Windows 11 than meets the eye.

According to preliminary testing, performance increases from Windows 11 might range between 2% and 11% on computers using hybrid CPUs such as Intel’s Lakefield chip. This is compared to Windows 10.

Long story short, it’s not projected to be substantially quicker than the current operating system. However, it is intended to provide a somewhat better overall experience.

According to Microsoft, there are several tweaks under the hood that help make Windows 11 a better performing operating system. There are some pretty substantial changes to the way it system handles apps and processes. Windows 11 will favor the programs in the foreground, making sure they’re allotted enough resources.

Source: How To Geek

Microsoft also stated that sleep mode will be terminated relatively instantly on computers equipped with 8th-generation CPUs and newer. This performance enhancement will allow computers to wake up from sleep mode quicker.

Microsoft will finally deliver Windows 11 to supported PCs on October 5th, after its announcement late in June this year. If you plan to grab this revamped update, check your computer. The next OS will only be supported if it has the appropriate compatible hardware.

Let’s Discuss Open Source

What is it good for?

Plain and simply, let’s put it this way: Because its design is publicly accessible, open source refers to anything that anyone may alter and share.

It is software that has the source code available for anyone to view, alter, and improve. Anyone who wishes to edit or enhance the code has complete access to the source code. Any changes, however, should be made available to other people as well.

While some users prefer open source software because they have more authority over it, this could also cause major issues.

According to TechRadar, last week, the Jenkins project learned that one of their outdated Confluence servers had been compromised. This was by the newly publicized remote code execution (RCE) vulnerability.

Jenkins is a well-known open source program that aids in the automation of some aspects of software development.

Recently a proof-of-concept exploit code for the Confluence vulnerability, tracked as CVE-2021-26084, became public, and it didn’t take long for threat actors to begin scanning and exploiting vulnerable instances of the popular collaboration platform, for nefarious purposes like installing cryptominers.

Synopsys, a technology business responsible for the open source security management system, Black Duck stated that 84% of codebases contain an open source vulnerability.

Just remember, open sourced software can become vulnerable if you are not controlling it.
