Computer hardware fault handling sequence

When the computer fails, first determine whether the computer failure is a software failure, if not a software failure to check hardware failure. Computer hardware failures are processed in the following order.

1. Judge The Fault

Before the repair failure, start with as much detail as possible about what happens before and after the failure (including which software is running before the failure, what devices are being used, and what prompts or exceptions have occurred after the failure); Observe the ambient conditions around the computer (including location, power supply, connection, other equipment, temperature and humidity, etc.); Observe the environment inside the computer (including dust, the connection, the color of the components, the shape of the hardware, the status of the indicator, etc., to observe the hardware configuration of the computer, including what kind of hardware is installed, the use of resources, the driver version of the hardware, etc. finally, through preliminary judgment, to find out the cause of the failure.

2. Positioning failure

After preliminary judgment of the cause of computer malfunction, the following according to their own knowledge, experience to locate the fault location and parts, can be the failure of the parts to replace the normal parts to detect (for their own do not know or do not understand, we must first consult with experienced people, to seek help).

3. Maintenance failure

Repair failure, to carefully check the failure of the specific fault parts type, is the chip damage or incompatible, in accordance with the specific circumstances, repair or replacement of damaged accessories, troubleshooting.
