Computers are indispensable learning and working tools in every family. However, after a long period of use, it is very easy to encounter problems. Accordingly, housewives can apply some standards to be able to preliminarily check the computer at home.
Check power source, connection system
If the computer does not start, the reason may be from the power source. It is necessary to carefully check the plug and charger cable to see if they are loose or broken.
With desktop computers, checking the power button at the back of the body and screen connection ports should be the first thing to pay attention to. Many cases where computers do not display images are simply due to loose signal cables.
Identify screen errors, audio signals
If the computer is still running but the screen is dark, try connecting to a separate screen or TV via HDMI port. If the screen displays normally, the error is in the computer's panel.
In case the machine emits continuous beep sounds when starting, this is a warning signal of hardware error from the motherboard, due to loose RAM or graphics card error.
Eliminating peripheral devices that cause conflict
When the computer is freeze-off or unable to access the operating system, disconnect all mouse, detachable keyboard, USB, or external hard drives. A broken peripheral can freeze the entire system.
Restart your computer to determine if the error is due to software or hardware. This is a simple but quite effective operation to rule out external causes.
Temperature evaluation, battery condition
Computers often break down due to the habit of placing the computer on a mattress to work because the cooling system is sealed. If the computer is out of power or running slowly, it is necessary to check the temperature of the case.
Too high a temperature will activate a self-disconnecting mechanism to protect components. At the same time, it is necessary to observe whether the battery is bulging or not to prevent the risk of fire and explosion, ensuring safety for users.
