What parts of the motherboard are prone to damage?

Generally, the motherboard is broken in the capacitor and the general chip, and the motherboard may not be able to be used for how long it can be repaired, no one can say for sure, and thousands of motherboards may also have problems, or they may be bought this year and discontinued next year.

The most common damaged part of an old motherboard is the electrolytic capacitor on the motherboard, especially near the CPU, which will often burst the pulp. High temperature is the main cause of capacitor pulp, high temperature causes the electrolyte inside the capacitor to boil, the pressure rises, when the pressure exceeds the pressure of the aluminum shell of the electrolytic capacitor, and finally exceeds the bearing limit of the vent and bursts. In this case, the capacitor can only be replaced.

Today's motherboards use solid-state capacitors, which has avoided this problem. Solid-state capacitors can still operate in high-temperature environments, maintaining a wide range of electrical properties. Its capacitance changes by no more than 15% over the full temperature range, which is significantly better than liquid electrolytic capacitors.

1. The most vulnerable thing is the capacitor, but the motherboard of about 800 yuan is already in the mid-range, and it should be used with solid-state capacitors, which is very strong!

2. The second thing that is easy to break is the integrated circuit chip, in fact, this kind of thing is very difficult to break under normal use. I am afraid of the influence of external factors such as voltage instability, 3, some interface equipment is also easy to damage due to frequent plugging and unplugging, but this kind of problem is easy to repair!

Basically, the general failure of the motherboard, you can change the corresponding parts, but the problem of motherboard burning caused by water ingress short circuit and other problems is big, because it is difficult to repair the problem in one place!

The motherboard of 800 yuan is already very luxurious for home machines, if no problems are found during the warranty period, plus regular dusting, no special circumstances occur, there should be no problem with three or five years!

I don't understand what motherboard you are asking, the vulnerable parts of different motherboards are different, if it is a computer motherboard, it is the cup power supply circuit and bridge that are easy to be damaged, followed by the memory slot and power supply circuit. If it is a power supply motherboard, it is the main power supply circuit and auxiliary power supply part that are easy to be damaged, followed by the voltage regulator circuit.

Vulnerable components on the motherboard. The main thing is capacitance. This is mainly due to the presence of heat-generating chips on it. If the heat dissipation is poor. Thermal breakdown can occur. Burst. Variant. Others are generally under normal circumstances. No damage will be caused.

Generally, the capacitors near the north and south bridges of the motherboard are the most likely to be damaged.

The main reasons are as follows;

Reasons for the movement of components: The chips and other components on the motherboard are of poor quality, resulting in aging and damage to the motherboard, resulting in the failure of the motherboard.

Human reasons: When using the computer, hot-swap hardware at will or touch various connectors with metal objects indiscriminately, resulting in motherboard failure.

Dust and static electricity causes: The motherboard malfunctions due to poor contact of the motherboard, short and rough leased circuits, or burning the chips on the motherboard due to dust or static electricity. Causes of poor exposure:

Due to rust, oxidation, weakened elasticity, pin desoldering, breakage, etc., various chips, sockets, and interfaces in the motherboard are not in good contact, resulting in motherboard failure.

Extended material: Solutions

Step 1: First of all, check whether the external wiring of the computer is connected, and plug in each cable again to see if the fault is eliminated.

Step 2: If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.

Step 3: If not, then clean the dust off the motherboard and check if the computer is in good condition.

Step 4: If the fault persists, unplug the reset cable on the motherboard and connect it with other switches and indicator lights, and then use the change cone short-circuit switch to see if it can turn on.

Step 5: If you can't turn on the computer, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on.

Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

Step 6: If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, motherboard, etc. Then, use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal, and replace the damaged equipment if there is a damaged device.

There is no such statement, as long as the computer temperature is not very high, the motherboard is not easy to damage.

The motherboard is a rectangular circuit.

It belongs to the board, on which the main circuit system of the computer is installed, generally there are BIOS chips, IO control chips, key and panel control switch interfaces, indicator plugs, expansion slots, DC power supply connectors of the motherboard and plug-in cards, etc.

The motherboard has an open architecture. Most motherboards have 6-15 expansion slots for PC peripherals to plug in control cards (adapters). By replacing these plug-in cards, the corresponding subsystems of the microcomputer can be partially upgraded, so that manufacturers and users have greater flexibility in configuring models.

Look at the brand, the IT industry.

There is a line, a second line, and a third line inside the bai. zhi。Division, the first line of **.

DAOs are probably 100+ higher than the second-tier version. The third line basically does not have the right to watch. The quality of the first line is undoubted, basically not bad, and it is good to repair the after-sales points if it is broken (there are few bad ones, and they are used for a long time, and the brands are:

ASUS, Gigabyte best others do not say), the second line ** cheap, but the bad rate is much larger than the first line, after-sales basically find a place to buy (the time used is longer than the first line, the brands are: Yingtai, Weconex...

It is recommended to go to ASUS Gigabyte, the same model is probably 100+ higher than the second line, you can't save money but worry, you must know that time is money.

In general, the possibility of accidents on a new motherboard is very small, but sometimes it is easy to have capacitor breakdown or slurry when it is used for too long.

It won't break with normal use.

Unless the voltage is unstable.

Or static electricity. The reason, and then the reason is that you spoof, generally there will be no problem with a few years.

There will be no problem with proper use. However, the voltage is unstable, the machine is turned on for a long time, and the dust is not cleaned and it is easy to cause damage.

A lot of cases, hehe.

Such as the irresistible, thunder split! Or sudden fluctuations in voltage.

Moisture or ash often conducts electricity, causing a back.

Short circuit, A: Or due to computer overclocking (external frequency), the frequency of all computer equipment will be increased, causing problems in the north and south bridges to burn the motherboard, etc.

It doesn't break under normal circumstances. Correct overclocking is no problem, it is recommended to buy an all-solid-state computer or a motherboard with double copper capacitors, they will have a longer lifespan!

The computer motherboard, as the name suggests, the core of the computer, anything, as long as it is well protected, will not be so simple.

The return is bad. A, hehe, it's not like the voltage downstairs said or something, of course, lightning strikes, think you can't do it with your own computer. As long as the circuit chip is well protected, the motherboard will generally not be broken, unless it is too inferior motherboard.

Generally, clean up the garbage regularly, don't let the wet tide short circuit, not to mention the voltage, you will also understand. Hehe, since you have a computer, take good care of it. Accompany you through the boring every day, hope to adopt.

If the temperature is too high, the motherboard has the function of self-protection, unless it is flooded or something hits.

The main ones are overheating, current surges (caused by lightning strikes or voltage instability), aging components, and poisoning.
