The weather in central Siberia

It can be judged by the sound-1: If it is a "click" or "buzz" sound, it is the sound of the fan. Open the chassis and check whether the fan screws are loose and the fan runs slowly. It may be that the lubricating oil in the fan is solidified (especially when it is too cold in winter) or there is no lubricating oil added to the fan. There are also general fans, which will fail if used for a long time. You'd better exchange it for a new one. 30 yuan a 2: If the sound is "喨喨喨喨", it is normal for the hard disk to read when it is turned on for the first time, but if it is loud, it may be that the hard disk is of poor quality, and the hard disk with poor quality will be louder.

If so, the long beep is a memory problem (usually the screen turns blue or the computer won't start). Pull up the memory and insert the golden finger with the eraser. If necessary, clean the memory slot. 4.CPU alarm sounds. When the CPU temperature exceeds the maximum temperature set in the BIOS, it will alarm that the CPU temperature is too high. Mainly check the heat dissipation of the fan and chassis. Turn on the computer to check whether the CPU fan is not rotating smoothly or the wind is not strong enough. Lubricate the central processing unit. Generally, the fan will fail or slow down after being used for a long time, and it needs to be replaced. Another possibility is that the CPU alarm temperature set in the BIOS is too low. You can enter the boot and press DEL to enter the BIOS settings to find "CPU Tempeue", which is generally set at 60-70 degrees. These situations can be solved manually by yourself. I hope it helps you.
