Nobody likes computer bugs. They are problematic, and some might be so complex that it’s better to leave them for professional technicians to fix. The good news is that there are some small but very common bugs that may occur regularly that you can deal with on your own.

Many of these bugs only require simple solutions. Learning to recognize these issues to fix them can save you plenty of money, time, and effort. Here are 10 of the most common computer bugs and how to address them.


1. Computer doesn’t boot

One of the most common reasons why a computer fails to boot is a power supply error. The basic solution is to check if your system is firmly and properly plugged into the power source. You should also test the power source with a device that you know works to confirm if it works.

2. Computer has slowed down

The main cause of this inconvenience is how long you have been using your computer. A device that’s more than two years old will experience this, no matter what its specifications are. 

There are three things you can do to solve this issue:

  • Scan for adware or malware.
  • Disable the start-up program.
  • Find resource-hungry apps or programs and shut them down.

3. The blue screen of death

Fixing what users call the “blue screen of death (BSOD),” also known as a stop error or exception error, will vary. In Windows 10, when you see a blue screen, you will also see a QR code along with the error message. 

Use your smartphone to scan the QR code. That will take you to a site with an explanation of the error message in more detail. It will also give you some recommendations on how to fix it.

4. Randomly shuts off and restarts

If your Mac shuts off randomly then restarts, there may be several reasons for this. Your computer might have various issues like faulty hardware, malware, or a corrupted drive, to name a few.

Pinpointing what exactly keeps your PC in this loop can be a challenge. It usually occurs after the Windows update. Some of the things you can do to solve this issue include updating drivers, scanning for malware or viruses, checking for hardware issues, and deleting bad files from the registry.

5. Overheating

This issue usually happens when your computer case doesn’t have a cooling system that’s powerful enough. That causes the components of your device to generate too much heat while operating. 

You can prevent your computer from overheating by turning it off for a while. In addition, you should also inspect the fan to see if it works properly.

6. Slow or unstable WiFi

When this issue occurs, you might start to feel like you can’t rely on it anymore. The classic solution to fix this problem is to turn your Wi-Fi router off then on again.

There is a technique to doing this properly. You must make sure the connection is completely off before turning the router on again. That will give you a new IP address while clearing your caches.

7. Monitor goes black

A monitor that goes black after a couple of seconds is an indication that there could be an issue with the screen adjustment or color quality. A simple fix is to press your monitor’s auto-adjust button. If that doesn’t work, you may want to change the color of the display from 32-bit to 16-bit.

8. Takes too much time to boot

You can fix this problem by opening the Task Manager. Click the Startup tab at the top. You will see all of the programs and apps that load when your computer starts up. A long list of these programs and apps could be the cause of your device booting up slowly.

9. Frozen screen

The most logical thing to do when your computer screen freezes is to reboot it. Unfortunately, doing that may lead to you losing unsaved work. Frozen screens can indicate registry conflicts, insufficient RAM, spyware, missing files, or corrupt files.

To reboot your computer when its screen freezes, press the power button and hold until your device shuts down. Restart then clean up your system so that it won’t freeze again.

10. Keyboard problems

Your keyboard might not be the problem even if it’s making noise or won’t type letters properly. The reason for that is you might have enabled the filter and toggle keys in the settings.

To disable these keys:

  1. Open Control Panel then click Ease of Access.
  2. Click the Change how your keyboard works button.
  3. Untick the box next to Filter Keys and Toggle Keys to solve the issue.


Not knowing what to do when an issue occurs usually leads to frustration. The good news is that now, you know the solutions are quite simple. If you’re still struggling to fix computer bugs, call in experts, as you might have a more serious issue with it.
