The computer is long and short, but it can work normally, and occasionally the screen is stuck

1 long and 1 short: RAM or motherboard error, you can check whether the memory gold finger is oxidized It is recommended to use an eraser, or check whether the capacitor of the motherboard is bulging.

One long and one short is a problem with the memory and motherboard.

Since it can work.

It is estimated that it is loose, you open the case and plug it in again.

It's most likely that your computer's hard drive is making a sizzling sound. Generally, when this noise occurs during operation, the computer will get stuck. Or you can also check the power supply or hard disk bad sectors.

Master Lu hard disk bad circuit inspection test, your range is indeed too wide. My notebook has been used for three years, and it will suddenly have a lot of noise, and then it will be fine after a while, but the computer can still be used, and the mechanical hard disk died directly last month, and it is impossible to store files. Let's take a look.

The only things that make noise in the computer are fans, optical drives, and mechanical hard disks, and it seems that your configuration does not have mechanical hard disks and optical drives.

The only thing that can make a sound is the fan, and it is possible that the fan has rubbed against a certain cable, making a sound and causing the data transmission to be unstable.

The inductance on the motherboard is relatively small, and there is generally no electromagnetic sound.

Just by squeaking, it's impossible to determine which hardware is making the sound.

This sound can be high-frequency noise from the inductor (in severe cases, whine), or it can be noise or resonance caused by unbalanced or worn fan bearings.

If it is an inductive sound, it is generally the power supply of the processor of the motherboard and the power supply module of the graphics card, where the current is very likely to produce this kind of noise.

If the fan is unbalanced or worn, resonant, etc., there may be a case fan, processor cooling fan, power supply fan, or installation problems.

Did you solve it? I also have this problem with my computer, which is frequent several times a day.

Some of the clicks on the vertical limbs of the laptop are normal sounds, but in some cases they are not normal

There will be sounds in the use of the notebook, mainly the motor rotation sound of the cooling fan, the sound of the axial fan blades twisting the air vibration, the sound of the air flow of the exhaust outlet, and the self-test of the optical drive when starting, these are the normal operation sounds of this book. The impeller shaft of the axial fan is misgraded, and the impeller is edged and emitted a card sound, and the sound duration is when the fault is light, which is manifested as a random dynamic sound, and if the casing of the fan is vibrate, the sound will change the rhythm. If the disc drive is faulty, it will be louder, but it will be louder, and there will be other noises at the same time.

Disks that may be damaged due to illegal shutdown, crash, or other reasons should be repaired (one for each disk or only C).

Built-in disk repair method:

The specific steps are as follows: select the drive letter C in my computer, right-click the mouse to select the properties, select "Tools Start Checking" in the pop-up drive properties window, and select "Automatically repair file system errors" and "Scan and recover bad sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing it according to the above method, a box will pop up, the point is, repair after automatic shutdown, and win78 select the Disk Check button according to the plan).

If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it).

Win78 can run the most basic is 4G memory,XP is 2G memory,It's easy to double,If you don't use this number,It is recommended to add memory (this is the number of practice,Not the number of theory)。

This book makes a "kaka" sound, some of which are normal sounds, but in some cases they are abnormal. The analysis is as follows:

1. There will be sound when the notebook is in use (except for the fanless ultra-low power consumption notebook that has just been launched). Mainly, the motor rotation sound of the cooling fan; The sound of axial fan blades twisting and air vibration; the sound of air flow from the exhaust vents; There is also a self-test when this book starts, making a few "card card" sounds; Sometimes the HDD will also have two delivery sounds. These are the sounds that come out of normal operation when this book is working.

2. After understanding what normal sounds are in the operation of this book, if you find that there are other sounds in this book, it is illegal, which is a sign of some kind of failure. For example, the "Kaka" sound in the question, first of all, you must judge the approximate sound production location, the duration of the sound (what is the rule), and whether there is any abnormal performance on the screen in order to judge the positioning.

3. Through careful observation, analysis of various phenomena found, combined with the structure of the book, the fault location can be basically judged. For example, the "Kaka" sound in this question does not have a detailed description of the fault performance, but based on the professional knowledge described above, the reference location of the fault can be basically deduced.

4. If there are no other abnormalities in the book, it can still work normally. The reason is that the impeller shaft of the axial fan is misaligned, and the impeller is edged and makes a "Kaka" sound. When the fault is mild, the sound duration is manifested as random dynamic sound.

If you knock on the casing of the fan, the sound will change the rhythm. In severe cases, the sound of "Kaka" is long, and it is useless to knock on the shell.

5. In this book, the other parts that can be rotated are only hard disks and optical drives. The optical drive will only be noisy if it is faulty, but it will be loud, and there will be other noises at the same time. If the hard disk emits this sound for a long time, the life is about to stop, and the hardware monitoring function of the system has already alarmed, and the screen displays the monitoring report results.

The fan is faulty, or the sound card is faulty.
