May I ask the seniors, how do you distinguish the quality of the motherboard?

This kind of thing can't be said.,It's best to go to the computer more by yourself.,Look at the motherboard workmanship、Materials、BIOS settings,After a long time,You'll have your own opinions.。

Hehe, I'm not a senior, and I'm not a master, so I can't solve your problem.

What can't be used is bad, what can be used is good, it's as simple as that.

Answer: The general motherboard is not so easy to break. After we remove the motherboard, don't immediately take the multimeter to check the circuit. It should be cleaned with a brush and alcohol. Then put it on the workbench to analyze the specific cause.

When placing it on the workbench, be sure to put a foam board or book under the motherboard. This is to prevent there from having broken metal around, and then when we light up the motherboard, it will cause a short circuit and burn the motherboard.

1) First of all, let's see with the naked eye whether the capacitor is bulging and leaking. This means that the capacitor is broken, and the worse capacitor is enough.

2) Also use a multimeter to measure the chip resistance, whether the chip capacitor is damaged.

3) If it is a black screen, a blurred screen, always restarting, blue screen, such a situation is generally related to the parts on the plug-in on the motherboard, we can use the replacement method to try it with a new one, whether it is broken, and then judge whether the motherboard is faulty.

1. Observe the motherboard battery: The motherboard battery is designed to keep the CMOS data and clock running. If the battery is dead, it cannot hold CMOS data. When choosing, pay attention to whether the battery is rusty or leaking, and if not, you can consider buying a motherboard.

2. If rust leaks, it may cause the entire motherboard to be scrapped due to corrosion. In fact, if the battery is faulty, it is best to return it directly.

3. Observe the production date of the chip: The speed of the motherboard depends not only on the speed of the processor, but also on the performance of the motherboard chipset. Generally speaking, the time difference should not exceed three months, otherwise the group will affect the overall performance of the motherboard.

For example, if one of the chips has a date of 0340 (the 40th week of '03) and the other chip has a production date of 1409 (the 09th week of '14), assuming that these two chips are on the same board, then the production time difference is about 11 years, so it can be judged that the quality of this motherboard is poor and it is not suitable to buy.

4. Observe the expansion slot insertion card: the way is to carefully observe the position and shape of the shrapnel of the slot, and then pull out the board after inserting it into the slot, and observe whether the position and shape of the shrapnel in the slot are the same as the original.

5. Check its appearance and weigh its weight: it depends on the thickness of the motherboard, and the thickness of the two motherboards is appropriate. Then observe whether the number of layers of the motherboard circuit board and the wiring system are reasonable.
