With a PC, we don't repair parts because they are too complex, we replace them. Everything starts by identifying which one is defect.
Test the power supply
Test the motherboard
Test another part
Simply by observing the symptoms, one can deduce a lot.
If no light turn on on the computer when you press the button, that means it is not powered .. So that is the power supply.
If the light comes on but absolutely nothing appears on the screen, it is a fundamental part (CPU, motherboard, graphics card, memory, etc).
If the computer starts but suddenly freezes or crashes without displaying error, it is overheating .. So it is a part that heats a lot (processor, motherboard, sometime graphics card or memory).
If the computer is terribly slow and can even make little metallic sounds, that is usually the hard drive, the only mechanical part that wears with time.
If the computer encounters completely random and diverse errors, it is often the memory that has small damaged areas that record the wrong information.
If the computer doesn't boot anymore
In this case, the diagnosis is more primitive. Only take a computer in good condition and install parts suspected to be defective in it in order to test them individually.
Hardware or software
While testing the parts is often the best starting point, sometimes the problem is software. In these cases, it is best to reproduce and study the symptoms and then ask Google to find a solution (see fixing bugs
). Ultimately, reinstalling the operating system
is a painful solution, but effective and universal with this type of problem. Scanning and removing virus
also often fix many problems.
Computer parts are toxic to the environment and are not suitable for traditional recycling, a recycler of this type of equipment is certainly not far from home, do a search on Google Maps!
