The computer gets too hot that it shuts down.
Dust Trapped in the Computer’s Heat Sink
If your computer is placed in an unsuitable location, dust will start to accumulate in it. This will cause your computer’s fans to get clogged and it will prevent the computer from cooling itself off. Make sure your computer’s heat sink is cleaned and stored in a proper location.
Check if air is moving out of the computer by putting your hands over the air vents. If you cannot feel any air ventilating, or your computer fans are making unusual noises then the fans need to be replaced. You can follow our guide on how to replace the fans.
Screen Malfunctioning/Screen flashes
The screen flashes when using it or the screen won’t turn on.
Screen Fails to Turn On
To make sure, the power supply isn’t the issue, connect the computer to a different power supply. If it still doesn’t turn on then you have to replace the power supply.
When a computer screen starts to show distorted images, or if an image on the computer screen stays on the screen for a long period of time then it is a sign that you need to replace your computer screen.

Computer Won’t Connect to WiFi
Your computer fails to connect to the internet.
Connected to Ethernet
Your computer may be connected to Ethernet instead of wireless internet (WiFi). Under your computer “Control Panel” tab, go to “Manage Wireless Networks”. Then remove all wireless connections by right clicking and clicking “Remove Network” from the dropdown menu. After doing this, close all windows and reboot your computer. Turn it back on, then scan for the “Wi-fi Networks” and click on “Connect” on your desired network, though it may ask for its password.
WiFi Modem is Off/Not Responding
Make sure your Wifi modem is turned on, as well as your laptop is turned on and accessible to WiFi. In your computer settings, you should have a “switch” to turn WiFi off and on. If this doesn’t work, reset your Wifi modem.
Short Battery Life
Your computer battery is constantly dying.
Older laptop batteries can tend to overheat while charging. It is recommended to purchase a new charger and replace it.
Damage to Laptop

The computer doesn’t let me access my files.
Constantly shutting down your computer without using the proper shut down procedure can cause data corruption. It is important to let the computer shut down/restart by itself.
If your computer suddenly changes in speed, unusual error messages pop up, and your computer applications aren’t functioning correctly or disappearing then you have a virus. Viruses are an external cause of data corruption. It is important to have an antivirus software on your computer.
Faulty Hard Drive
If your files are constantly disappearing/moving or if your computer frequently crashes when booting up then you have a faulty hard drive and it needs to be replaced. Follow our guide on how to replace your computer’s hard drive.
