First, about the abnormal sound of the boot, but it will be fine after a while. This is why there is a cooling fan in the chassis. At present, the motherboard of the new machine can adjust the voltage of the cooling fan according to the use of hardware such as CUP by software in the computer. The fan speed is high when the computer is busy and low when the computer is idle. At first, due to the system startup, software loading and other factors, the computer runs at full load, so the voltage and speed of the fans reach the highest, and some fans with low quality will make noise when the lubricating oil is not fully lubricated. After the machine is started, it enters a relatively idle state. On the one hand, it reduces the rotation speed of the fan, on the other hand, it is basically fully lubricated, so the noise is small. If you turn it off and turn it on again, the abnormal sound should not be too obvious in a short time, but it will be obvious when the interval is long.

Solution: the fundamental solution is to see which fan makes abnormal noise and change it-no matter how high the speed of a high-quality fan is, there will be no big abnormal noise; Another idea is to reduce the burden of machine startup, slim down the operating system, reduce unnecessary startup items, and choose antivirus software that takes up less machine resources. In this way, your machine can be started lightly and this problem will be alleviated.

Second, about restarting the black screen today. Generally speaking, this is a memory problem. According to the landlord's description, there has been a short beep after the restart, which should be an alarm when the machine is self-checking. The alarm sounds of different CMOS chips are different. Generally speaking, the continuous short beep is mostly a memory problem. It is estimated that it is caused by poor contact of memory chip, long-term abnormal noise and excessive vibration of the building owner's machine. It is suggested that the landlord completely turn off the power supply, pull out the memory stick, and wipe the pin of the memory stick with an eraser (many people call the pin of the memory stick the golden finger, but that is actually wrong. . . ), carefully clean the memory stick with a brush, then insert the memory stick back and restart it.

The main reason should be the memory card, which does not rule out poor contact of CPU or graphics card. However, if it is the latter, the alarm sound should not be like this. So look in this direction first, hoping to help you solve the problem as soon as possible. If there is anything unclear, please continue to ask questions.
