My computer was loud when it turned on

If the hard drive is so loud, then the machine will not be able to start. It should be the sound of the CPU fan. This sound is loud when the machine is cold, and when the CPU works, the temperature comes up, the lubrication will be better, and the sound will return to normal.

This problem is that the lubrication of the CPU fan is not good, you can remove the fan, lift the label in the middle of the fan, the bearing will be exposed, just add a drop of oil. If you don't have engine oil, you can use thin oils such as watch oil and transformer oil.

This is a process similar to warm-up. It's the fan inside that rings. The fan runs by default. This is because there is no data coming out of the sensor yet. Let the system discern who did it how

My previous machine was the same, generally the sound of the fan, the power fan has been used for a long time, the lubricating oil is dry, it is recommended to go to some lubricating oil or change to a new fan.

There may also be a CPU fan, the CPU fan is running at full speed when it is turned on, and the system returns to normal after the desktop is displayed, and the motherboard adjusts the fan speed according to the CPU temperature, so it comes down.

If the hard disk has a loud sound, it is a bad sector, pick up the hard disk and test it.

It's normal that the hard disk is ringing, and there are many things to start when you boot up, and the hard disk is very busy, so it will ring!

You don't know how to use a Dell machine, it's the sound of a fan turning when you first wake up. Is there a few seconds when it doesn't ring? That's what the Dell machine looks like

Hard disk? Generally, it is the case power supply and the fan that I wonder if I will get it wrong.

Why don't you test the hard drive?

The problem does not matter what I also have the sound of the hard drive.

When the computer starts up, check the memory first, and then wipe it back and plug it in tightly. If it can't be solved, there is a problem with other hardware, give you the most complete information, and read and judge it carefully according to the specific situation: if you look at these carefully and carefully and do not help you, send them directly for inspection.

Detailed explanation of the motherboard alarm sound.

1. "Didi...""Continuous, short tones are generally common when there is a problem with the power supply of the main unit.

2.The sound of the ambulance "Woo la Woo La" was accompanied by the sound of the starter non-stop.

This situation is the system alarm sound of CPU overheating, mostly because of dusting inside the host, cleaning the CPU cooler or because the CPU fan is replaced with a new one, because the installation is not in place.

3."Tick...."Tick....", a continuous interval of long tones. The sound of memory alarm is generally due to loose memory, poor contact between the gold finger of the memory and the memory slot, oxidation of the gold finger of the memory, and failure of a chip in the memory.

4."Tick...., Didi" is a long and two short continuous chirps.

This is a graphics card alarm, usually the graphics card is loose, the graphics card is damaged, or the power supply part of the graphics card of the motherboard is faulty.

5.There is no movement after two long tones of "beep", and after a while, you will hear the sound of "squeak" reading floppy drive.

If there is an image display, it will indicate that the system will boot from the floppy drive and is reading the floppy disk. If there is no floppy disk in the floppy drive, the system will prompt that no system cannot be started, and the system is suspended.

6.Press "CAPS" under the win system

lock" and "num

lock" and "scroll

lock", the PC speaker of the host has a key-like sound of "Di".

7.A short "tick" sound, under normal circumstances, this is the prompt sound that the system self-test has passed and the system has started normally.
