Source error (PSU - Power Supply Unit)
The source is the electricity supply department for all components in the computer. When the source is problematic, the computer may not be able to start, or automatically turn off suddenly while it is running. Common causes are overloaded power sources, burns, or broken power lines.
Recognizable signs:
The computer will not output when the source button is turned on.
The computer automatically shuts off or reboots suddenly.
The source fan does not record or make strange noises.
hard drive (HDD/SSD) error
hard drives are a place to store important data. When the drive is faulty, data can be lost or inaccessible, the computer warms up slowly or there are error notifications related to the drive.
Recognizable signs:
The computer runs abnormally slowly or is suspended when accessing data.
A strange shout appears from the hard drive (especially the HDD).
The computer reported the error "No Boot device found" or Blue Screen.
RAM error
RAM helps the computer temporarily process data to make applications run smoothly. A RAM defect often causes the computer to run slowly, hang up, or re khoiart abnormally.
Recognizable signs:
The computer is suspended or has a blue screen when it is warmed up or running heavy software.
The computer reports a memory-related error when turned on.
The application often crashes or crashes suddenly.
Screen card error (GPU)
Screen cards determine image quality and graphics processing capability. When the GPU is faulty, the display image is distorted, crashed, or the computer is stunted while playing games and graphics software.
Recognizable signs:
The display shows streaks, blurred vision or inaccurate color.
The computer is hanging or automatically turned off when running a heavy graphics application.
Screen driver cannot be installed or is constantly broken.
Motherboard errors
The main mach is the central part that connects the components together. When the home network bus has a problem, the computer may not start or operate unstably.
Recognizable signs:
The computer did not come up with the source even though the other components were still working normally.
Connection ports such as USB, audio are not working.
The computer automatically shuts off or restarts continuously.
Faulty air conditioners and cooling systems
A grille acts as a cooling gas to the components inside the computer. A broken fan or an ineffective cooling system will cause the computer to overheat, causing hanging or a power outage.
Recognizable signs:
The fan does not rotate or rotates slowly.
The computer is abnormally hot, especially when operating for a long time.
The machine turned off automatically to protect against overheating.
