[Know yt] No response to computer startup from three aspects

Yulin MufengXiaobian suddenly remembered that he had handled such a situation before, and there was no response after the computer started up. In fact, there are also several possibilities for such problems:

I. The first thing to check is whether the power cord is plugged in and whether there is a problem with the contact. This is a commonplace. I may not be able to explain this kind of mental retardation.

2. the power supply is broken. This is a common fault and it is easy to think about it. If the power supply is broken, press the power key and the system will not respond at all. Of course, it is better to solve the problem, more than 80 yuan to change power.

3. This isChinese CabbageDifficult to judge, because few people think about it and it is not easy to find it. Open the chassis, carefully observe the motherboard, and check the capacitor,Download topicSome may have been bulging. Yes, the capacitive drum kit will also generate a situation where the host does not respond by pressing the power key, because the motherboard is the hub connecting all devices, so that is not a point, the capacitance of the Main Board is bulging, and the main board is working, so that the power supply will not provide power, so no response.
