host computer fails, which hardware is the easiest to damage?
Generally speaking, the CPU is not easy to damage, unless the voltage is too high, it may burn the CPU, but the CPU has integrated a voltage protection circuit, if the voltage is too high, it will directly power off and restart, or shut down. Keep running. Of course, some CPUs allow overclocking, but there is still a voltage range that allows overclocking. It does not increase the voltage indefinitely, but also integrates an over-voltage protection circuit. If the other hardware of the computer is broken, the CPU may not be broken, the life span is very long, and the damage rate will not be too high. The damage rate of
power supply is not very high, there is a certain range of voltage fluctuation, and the probability of damage is not very large under normal voltage and current conditions. But it is necessary to ensure that it is used frequently, instead of using it for half a year or a year, which will cause some power supplies to fail or be directly scrapped. Of course, in the case of long-term use in harsh environments, the voltage fluctuates high and low, and the current is also unstable, which may cause power failure. However, in a household environment, the power failure rate is not very high in normal use, unless a brand-name power supply is used.
The damage rate of the hard disk is not very high, but it should be divided into hard disk material. Mechanical hard disks are not easily damaged under normal use. Although solid-state hard disks have fast read and write speeds, the damage rate is very high. Over ten years.
The damage rate of the memory stick is not very high. Some brand machines directly solder the memory to the motherboard, or use sealant to glue the memory stick to the motherboard to reduce the failure of poor contact. Often the memory stick has not been used up yet, it has been updated. The same is true for other hardware, most of which have not been used up yet and have been updated. Memory sticks are not easily damaged hardware, but they are prone to poor contact. So, is the fault of the memory module poor contact due to the memory module or the motherboard?
should be regarded as the reason of the motherboard. The motherboard has become the hardware that is most likely to cause poor contact and damage. Due to the design of the metal contact piece, it may have poor contact with the gold finger of the memory module, or it may cause poor contact between the metal contact piece of the CPU base and the CPU.Poor contact of the video card or card base metal contact sheet may also occur. It is only the poor contact, but many other problems will follow, which will cause a lot of trouble for users. Poor contact can clean up the dust, wipe the golden fingers of the memory sticks, graphics cards, and network cards, and re-plug the CPU. These are minor faults. If the chip or capacitor soldered on the motherboard fails, it is a pure hardware fault. The motherboard will have a certain life span, which is already ordered at the time of design. Generally speaking, the warranty period of the motherboard is three years, and some only have one year. In other words, some motherboards, especially those of second- and third-tier brands, will lose their warranty beyond one year. Of course, there is also the fact that motherboards of first-tier brands will go down after one year. The liquid capacitors used in the old motherboards are easy to explode, and the Northbridge chip sometimes overheats and it is easy to hang up. Although most of the motherboard capacitors now use solid capacitors, which are not easy to burst, other chips are not necessarily better. Some "physiques" are weak, and problems will occur when voltage fluctuations are encountered. Of course, you can’t just buy a motherboard by looking at the brand, the motherboards of big brands will also have malfunctions. Moreover, after many motherboards fail, non-professionals cannot detect where the fault is. Some motherboards are fixed in the chassis for a long time. They have to endure the resonance of the cooling fan behind the CPU and the resonance of the fan behind the graphics card. They are also responsible for data transmission and the operation of various peripherals. If they are removed from the chassis, they will fail. . And after deformation in the chassis, failures will also occur. Some motherboards are normal in the working case, but it is abnormal when it is removed. It cannot be lighted, and it cannot work normally when installed in other cases. In fact, it has been deformed, causing some components to fail to operate normally.
It can be said that the motherboard is the most easily damaged hardware in the computer case. Of course, it is necessary to evaluate the performance of various hardware comprehensively. If you use inferior solid-state hard drives or hardware such as memory or power supplies, it is possible that these inferior hardware are damaged first, and the motherboard is strong. Under normal circumstances, the failure rate of the motherboard is very high, but as long as it is used normally, there is no harsh environment, and it is operated properly, it is not easy to damage. Unless you buy a miscellaneous motherboard, or a second-hand motherboard, or a shoddy motherboard, the reality is that not only these motherboards are easily damaged,Even new motherboards are prone to some problems, and the quality is really worrying. Perhaps, motherboard manufacturers know the obsolescence cycle of computers, they must use some weaker "physical" components, save manufacturing costs, but let consumers pay the bill, and the motherboard must be replaced in one piece, which is a bit unnatural. It might be better if motherboard manufacturers promise to replace new motherboards for free for life. However, the speed of computer update is very fast, even free replacement for life is not feasible. The old motherboard is damaged, and I want to replace it. I can’t find the corresponding model. I can only add money to buy a new motherboard. After buying a new motherboard, all other hardware must be replaced. It is better to buy a new computer directly.
It turns out that even if the motherboard manufacturers have approved the computer elimination cycle, some motherboards have frequent failure rates, or they will be scrapped after a certain number of years...
