Anonymous users2024-01-24Types of common computer failures and their causes.
Generally speaking, computer failures include hardware damage and software program errors, the former is a hard failure, and the latter is a soft failure. Hard faults can be divided into three categories: device faults, mechanical faults, and man-made faults. Device failures are mainly caused by components, connectors, and printed boards; Mechanical failures are mainly errors in external devices, such as keyboard keys malfunctioning; Man-made failures are mainly caused by the machine not meeting the requirements of the operating environment conditions or improper operation.
The failure of the component itself, such as capacitor expansion, bursting, blackened resistor, serious heating of the manifold, etc., may also be caused by too much load, insufficient power supply or CPU overclocking, in addition to its own quality problems. In general, if the computer that has just been installed fails, it may be a hardware failure or a software failure, but the possibility of hardware failure is relatively high. Sometimes, the failure of the newly installed computer is often caused by poor contact, such as various plug-in cards, memory, CPU, etc. and poor contact with the motherboard, or poor contact with power cables, data cables, audio cables, etc.
