What it Means When Your Computer Freezes

If your computer freezes, it could be a software or a hardware problem.

When devices are frozen, it means the windows on the screen have stopped responding. Everything has become at a stand-still. This can be quite frustrating to users, especially when working remotely or finishing up daily online schooling.

The easiest remedy comes as simply restarting your computer. Sometimes, that may not help. Here are a few reasons why your PC freezes up:

Software Issues

Updating any and all software is crucial to keeping your PC running smoothly. If your operating system is out-of-date, this could cause frozen windows. Make certain all applications are legitimate. Any malware can also hinder its performance.

Your Windows OS, or any other operating system you have installed, may be corrupted. If that’s the case, uninstall them, and re-install. We wrote a blog post recently about an unsupported Windows 11 OS that could spell disaster if downloaded and installed.

“With their exciting news, rumors have spread to allow users to download the unfinished, not-yet-announced Windows 11. The build leaked overseas, and Microsoft has expressed to users not to do so. On top of that, hackers have been busy taking advantage of this opportunity.”

Hardware Issues

Defective hardware can create malfunctions to the performance. Overheating can potentially disturb the quality of a PC. Fans are designed to keep them cool. All devices require ease of airflow to keep the fans running properly.

Also, any recent installations of components need to be considered a likely culprit. Try removing them to see if that’s the issue.

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.

Unsupported Windows 11 Could Spell Trouble

Microsoft recommends you not download Windows 11 early

If you plan on updating your operating system to Windows 11 this fall, you will want to check your computer. The reasoning behind this is the upcoming OS will only be supported if it has the correct supported hardware.


  • Unsupported devices have 52% more kernel mode crashes (Blue Screen of Death errors). On the other hand, compatible devices provide a 99.8% crash-free experience.
  • On unsupported devices, app hangs are 17% more likely. For first-party apps, Microsoft observed 43% more crashes. -Source: Microsoft

If your computer does not have the right hardware, it will have limited support, or won’t be supported at all. Microsoft maintains its stance on Windows 11 requirements. They stated clearly that only supported devices will receive the new operating system. An unsupported operating system could, unfortunately, increase the risk of BSOD (black screen of death) or other technical errors.

If you ignore Microsoft’s advice and run the officially unsupported operating system on your device, you may not receive any quality updates via Windows Update. Microsoft officials have said that they couldn’t guarantee these devices would get monthly updates like cumulative or optional updates.

Ventilating Your Computer

Computers require ventilation and fans to ensure its hardware’s longevity. Overheated components can cause the PC to crash and fail. This could result in loss of data and personal information.

Dust Buildup

Over time, dust builds in computer cases and even laptops. This causes obstructing fans and restricting air movement. Unfortunately, trapping heat and preventing your PC from adequately cooling itself could cause even bigger problems. Clean your computer’s casing on a regular basis.

Now, if dust isn’t clogging it but it’s still overheating, the fan may not be working properly. It may need replaced, or it might have just come unplugged.

Another tip to remember is to keep the room clutter-free and cool. Make sure nothing is blocking the vents or fans. A warm environment could spell disaster for your computer. Humidity often becomes a culprit of PC issues.

Prolonged exposure to high humidity corrodes the components inside your computer, similar to the way damp air on a rainy day rusts metal left outdoors. When the computer’s metal and electronic pieces corrode, they can lose their conductivity, resulting in short circuits or complete computer failure. Computers should be kept in areas where the humidity level is around 45-50%. Keep them away from humidifiers and damp areas like bathrooms to prevent corrosion.

Temperature Changes

Like the inside, it’s best not to leave your device out in the sun. Doing so can also ruin the battery. Sources say to keep the temperature within 70-80 degrees. Apple says their devices include an automatic regulation, shown below:

iPhones come with a temperature sensor, so if the device overheats it sends a notification to the user. It immediately pauses any phone activity until the temperature drops.

Why Should You Back Up Your Computer?

Unfortunately, files become lost or corrupted due to malware or hardware crashes. It’s times like these that you have to be extra careful.

Backing up your computer is the solution to these issues. Microsoft Support shares on their blog how to back up and restore your computer. They also state the importance of backing up on a separate hard drive.

“Do not back up files to the same hard disk that Windows is installed on. For example, do not back up files to a recovery partition. Always store media used for backups (external hard disks, DVDs, or CDs) in a secure place to prevent unauthorized people from having access to your files; a fireproof location separate from your computer is recommended. You might also consider encrypting the data on your backup.”

Windows Support

Don’t wait until the worst happens on your computer. Keep your privacy safe and secure.

Slow Computer Could Be Because of Browsers

Browsing the internet has become one of the fastest way to gather information for personal and work use. It can, unfortunately cause problems to your computers performance.

That’s because browsing utilizes CPU and memory resources at multiple levels. Any kind of program being used can have an affect.

According to Mashable, “A single web page with video may use 20-30% of your CPU. A few of those, or any one more than 50%, will clearly affect performance. If the memory used by all of your browser processes combined exceeds one-half of your computer’s memory, your browser is likely affecting performance, too.”

Some browsers, such as Chrome, offer up handy tools in their Settings, sharing details about processes and possible culprits. Extensions added to your browser could also cause problems, and may have to be removed and added back on again.

MacOS Update Hiccups with Crashes

If your Macbook has updated to Catalina OS 10.15.4 and you’ve experienced crashes, you’re not alone.

Yesterday, many users blew up Twitter about their issues. Since the update release, many Macbooks have crashed after being woken up from sleep mode. Although they have reached out to users on Twitter, Apple Support has yet to respond to this bug in an announcement.

One Twitter user stated, “Brand new 64gb macbook Pro and same issue. Nothing installed vanilla just got, instantly crashing. One thing open was Safari on BBC homepage. Left 15 mins came back crashed. Continously since. Installed stuff same. Reformat same. Big problems unusable.”

However, after scanning through Twitter feed, one user said that they were able to disable automatic graphics switching.

It’s completely unclear if that will work for every Macbook user who is currently experiencing issues. But it may seem like it’s worth a try.

Is Your Computer One of the Million Susceptible to Malware?

Yes, you heard that right.

Last month, Microsoft warned users that their computers may be unprotected. While they released fixes back on the 14th of May for a ‘Remote Code Execution vulnerability‘, Microsoft explains that it’s ‘wormable‘ and could cause a handful of issues to your computer.

Simon Pope, the Director of Incident Response, Microsoft Security Response Center (MSRC) includes, “It’s been only two weeks since the fix was released and there has been no sign of a worm yet. This does not mean that we’re out of the woods. If we look at the events leading up to the start of the WannaCry attacks, they serve to inform the risks of not applying fixes for this vulnerability in a timely manner. “

Their fix to this vulnerability: simply update your system as soon as possible.

Better to be safe than sorry.

Windows 10 Update Won’t Restore

Word of Caution to Windows OS Users:

Updated on May 17th, Windows Support posted on their forum, explaining that, “you cannot restore the system to a restore point after you install a Windows 10 update.” This occurs when you install Windows 10 on your computer and turn on System Protection, then adding a R1 point to reinstate the system. A Stop error (0xc000021a) then shows up on your monitor. And restarting your computer only does nothing to fix the issue.

Windows claims that this is a known issue, including the following information on how to recover:

“During the system restore process, Windows temporarily stages the restoration of files that are in use. It then saves the information in the registry. When the computer restarts, it completes the staged operation.

In this situation, Windows restores the catalog files and stages the driver .sys files to be restored when the computer restarts. However, when the computer restarts, Windows loads the existing drivers before it restores the later versions of the drivers. Because the driver versions do not match the versions of the restored catalog files, the restart process stops.”

It’s possible to force a shutdown of the computer (this might have to be done a couple of times) and then enter the WinRE if a glitch occurs.

How do you do this? Windows can help:

In the Windows Recovery Environment (or WinRE), follow these steps:

  1. Select Troubleshoot Advanced options More recovery options > Startup settings, and then select Restart now.
  2. In the list of startup settings, select Disable driver signature enforcement.

    Note You may have to use the F7 key to select this setting.
  3. Allow the startup process to continue. As Windows restarts, the system restore process should resume and finish.

These steps restore the computer to its “R1” state.

Steer Clear of this Issue by doing this:

  1. Select Start > Settings > Update & Security > Recovery.
  2. Under Advanced options, select Restart now.
  3. After WinRE starts, select Troubleshoot Advanced options System restore.
  4. Enter your recovery key as it is shown on the screen, and then follow the instructions in the System Restore wizard.
