As the core of the computer, the motherboard has a high probability of failure due to its circuit integration. Poor heat dissipation, capacitor breakdown, etc. will cause the entire system to be paralyzed. Most people think that as long as there is a problem with the motherboard, it can not be repaired by conventional methods. Therefore, once a computer motherboard fails, it is often a new thing.
In fact, although most components of computer motherboards are highly integrated chips, there are also resistors, capacitors, diodes, and triodes commonly used in ordinary circuits, especially some high-power tubes often pass large currents, so Due to the large heat generation and the size limitation of the computer motherboard, it is impossible to make the heat sink very large, especially some cases are small and the heat is not easy to dissipate. Therefore, these high-power tubes sometimes work at temperatures exceeding their maximum operating temperature for long-term use It is inevitable that problems will occur. Next, I will briefly introduce the main board failures and troubleshooting methods I encountered in the computer. Friends who have encountered similar failures may wish to learn from my repair experience. Maybe they can restore your computer’s power and save you Many expenses.
First, the computer fails to start, the motherboard dust is too fierce.
Failure performance: The assembled compatible machine often fails to start recently, and occasionally it can enter the system is also frequent crashes, affecting normal work and entertainment.
Fault summary: Dust is the invisible killer of the computer. The accumulated dust prevents heat dissipation, easily damages components, and can cause short circuits in wet weather. Dust also has a great impact on the mechanical parts of the computer. Therefore, it is extremely important to regularly give love to the machine.
Second, poor heat dissipation, leading to damage to the motherboard capacitor troubleshooting
Failure performance: After the assembled compatible machine continued to play the game for seven or eight hours, all of a sudden the screen became black and did not respond. After pressing the power button of the chassis again, the machine still did not move.
Fault summary: Due to the large number of motherboard manufacturers, the materials and workmanship are uneven. Many second-tier motherboards of different brands not only do not work hard, but they are not sufficient in materials. In addition, the heat dissipation environment is not good, which can easily lead to Capacitors or other components are burnt out. Therefore, when choosing a motherboard, you must choose a product from a first-tier manufacturer. In addition, even if the motherboard is made with sufficient materials, if it is used in a high temperature environment for a long time, the capacitor element will burn out over time. Everyone must pay attention to do a good job of heat dissipation to prevent accidents.
