Computers aren’t perfect; they are vulnerable to many things and can screw up by themselves very quickly. However, the major problem that can cause havoc is a user error. Ignorance could lead to wrecking your system and knowing these potential hazards can save your system and can save you a lot of money.

I will list 4 tragic computer accidents with disastrous consequences that you can prevent. But please note that these are not the only accidents, there are many accidents out there waiting to happen. These are just the major one that has bigger consequences. Following these advice will save your computer and your pocket as well, so without any further ado, let’s take a look at the accidents you can easily prevent.

1. Leaving your computer dirty

Let’s start of with the most common problem; don’t leave your computer dirty. Dust causes your components to overheat which can damage your components. Keeping the fans and PC components clean is a good practice and very important. Use a hair dryer or a compressor to clean your computer and clean it every 3 – 4 months.


The second most important thing is to clean your CPU fan and heat sink. To do this, remove your case cover and carefully remove the CPU fan and heat sink. Use alcohol to remove the thermal paste from the CPU and clean the fan and heat sink thoroughly. Remove any dust from your case using the hair dryer or compressor, then carefully put everything back together.

2. Dropping your hard drive

Hard Drive

The most important component in the computer is the hard drive. It’s the most sensitive piece of equipment since it holds your sensitive data, pictures, videos and so on. However, unlike Solid State Drives which have no moving parts, hard drives are mechanical devices that have a head which can read and write data very fast. This head floats on a platter that is coated with non-electrostatic lubricant, which protects it from minor collisions.

However, you will lose your essential data if this platter gets damaged. You should also never open your hard drive for any reason, since hard drivers are made in air filtered rooms.


As such, you need to be very careful with hard drivers, especially external hard drivers that you constantly move. Make sure you place your external hard drive on a solid surface to avoid vibrations and movement. Avoid carrying your laptop from one place to another when it’s turned on, as any sudden jerk can damage the fast spinning hard drive.


Backing up your data is important since the chances are slim if you dropped your hard drive. The best practice would be to back up your most important data to two hard drivers to avoid any data loss.

3. Using registry cleaners/boosters

As I mentioned in my previous article, using registry cleaners and memory boosters are basically useless. They can actually cause more harm than good. They claim to speed up or clean your system, but they have the potential to cause harm more than the good.

The registry is a very important program for the system, and using registry cleaners could wipe out important registry entrees which can render your programs or the operating system useless. Thus, understanding the importance of the registry is very important and you should never play with it.


The best program to use to clean up your system is Ccleaner. It’s the most widely used cleaning program in the world. However, it’s always a good practice to know the limits before you proceed with cleaning.

4. Downloading unsafe apps

Virus Alert

Windows is the most widely used OS in the world; hence why it’s the most vulnerable. Hackers or malware writers spend time looking for vulnerabilities in the OS, because they know they will most likely get a hit and then take advantages.

One of the most dangerous types of malware is a keylogger. A keylogger is basically a program that runs in the background and can record every single keystroke entered and sends it to whoever is disturbing it. This gives the disturber a record of everything you typed, from Facebook passwords to your banking details. The damage can be devastating, and the worst part is you might not know it’s being happening, until your data is being sold or someone is using your identity and stealing money from your accounts.


The best prevention from such malware is to download apps from trusted websites such as cnet.com or filehippo.com. You also need a good antivirus such as Malwarebytes and a secure browser such as Mozilla or Chrome. You might also want to consider monitoring your system for any suspicious activity on your computer.

– How to prevent an accident

All of the above points are accidents waiting to happen. Thus, knowing how to prevent them is crucial. Keep in mind that a computer is like a baby, if you don’t look after it, then it won’t look after itself. Always clean it from any dust, keep it up to date, scan it using antivirus products regularly and never download anything from websites that you are not familiar with.
