Nobody likes computer bugs. They are problematic, and some of them might be so complex that it’s better to leave them to professional technicians. The good news is that there are some small but very common bugs that may occur regularly but which 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 for this is a failure in power supply. The basic solution is to check if your computer 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 there is enough power.

2. Computer has slowed down

The main cause of this inconvenience is how long you have used your computer. For instance, a computer 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” error (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 a smartphone to scan the QR code. This 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, and a corrupted drive, to name a few. 

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

5. Overheating

This issue usually happens when your computer case doesn’t have a cooling system that’s powerful enough. This 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 WiFi router off, then on again. 

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

7. Monitor goes black

Your monitor going black after a couple of seconds of display 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 this doesn’t work, you may want to change the color of the display from 32bit to 16bit.

8. Takes too much time to boot

You can fix this problem by opening the Task Manager. Click on the Start-up 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 this 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 it has a frozen screen, press the power button and hold it until your device shuts off. 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 it won’t type letters properly. The reason for this is that you might have enabled the filter and toggle keys in the settings. 

To disable these keys:

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

Conclusion

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