What Is a Memory Error?

Memory failure is a common failure of computer hardware. There are several reasons why memory is not compatible with the motherboard. Inserting the memory on other motherboards can run stably and reliably for a long time; inserting other memory on the malfunctioning motherboard also runs reliably and stably, and no alarm appears. But when you put the two together, the alarm sound of "" appears. Replaceable memory or motherboard to solve.

Troubleshooting method

First, the most common fault: memory corruption, leading to memory alarm at boot

This kind of failure is often encountered by people, most of which are fine the night before. When I turn on the machine the next morning, I don't hear the usual "Beep", but "Beep, Boom, Boom ..." No image is displayed on the monitor. This kind of failure is mostly because the computer's operating environment is not good and the humidity is too high. During long-term use, the surface of the gold finger of the memory will oxidize, causing the contact resistance between the memory gold finger and the memory socket to increase, preventing current from passing. Therefore, the memory self-test error. It appears to be "beep" ringing immediately after booting, which is what we usually call "memory alarm".

The processing method is also very simple, just remove the memory, carefully wipe the gold fingers on both sides of the memory with an eraser, and then insert it back into the memory slot.

Note: When scrubbing the golden finger, do not touch the golden finger directly with your hand, because the sweat on the hand will adhere to the golden finger, and after a period of use, it will cause the golden finger to oxidize again, and the same failure will occur repeatedly.

However, there are several other reasons for this type of memory alarm:

1. Memory is not compatible with the motherboard

Inserting the memory on other motherboards can run stably and reliably for a long time; inserting other memory on the malfunctioning motherboard also runs reliably and stably, and no alarm appears. But when you put the two together, the alarm sound of "" appears. Such failures can only be solved by replacing the memory.

2. The quality of the memory socket on the motherboard is poor

It appears that the alarm sound of appears when replacing multiple brands of memory. Occasionally, one of the memories does not alarm, but it may alarm after shutting down and restarting. This kind of failure mainly occurs on low-end motherboards of two to three hundred yuan. The reason is that the price of the motherboard is low and the quality of the memory slots used is poor. It can only be replaced by replacing the motherboard.

3. A memory chip is faulty

This kind of failure is relatively serious. During the power-on self-test, the host can find that there is an error defect in the memory, and cannot pass the self-test, and issue a alarm sound to prompt the user to check the memory. For this kind of failure, insert the memory on other hosts and check whether there is the same "beep" sound. If there is, it can be determined that there is a memory problem; if not, it may be the first or every two reasons mentioned above.

4. Memory alarms caused by other faults

This type of failure is not common. It may be a motherboard failure or a CPU failure, which causes a memory alarm. It can only be solved by removing them one by one.

Second, common failure 1: memory corruption causes the system to frequently report registry errors

This kind of failure is relatively common, showing that the system can be started normally, but when entering the desktop, the system will prompt a registry read error, you need to restart the computer to fix the error, but after restarting the computer again, the same failure still occurs. For such problems, we can enter safe mode, type the "MSCONFIG" command during operation, remove the "V" in front of ScanRegistry in the "Startup" item, and then restart the computer. If the fault is removed, it means that the problem is really caused by a registry error. If the fault still exists, you can basically determine that there is a problem with the machine's memory. At this time, you need to use the replacement method and replace it with a good-performance memory module to check whether it exists. Same failure.

Sometimes, if you do not perform disk defragmentation for a long time, if you do not check for errors, it will also cause a system error and prompt a registry error. However, for this type of problem, after you disable the ScanRegistry operation, the system can run normally, but the speed will be Noticeably slower. For such problems, the best solution is to back up important information first, and then reinstall WIN98.

Third, common failure 2: memory corruption causes the system to prompt "an error occurred while decompressing the file, a file cannot be unpacked properly"

This kind of failure is common in the process of installing the system, and often quit the installation accidentally. In fact, this is often caused by the poor quality or poor stability of the memory. Most problems are solved after the memory is replaced. This kind of problem will appear the same prompt message whether you install directly from the CD-ROM or from the hard disk. Although it is similar to the problem that we cannot read a file during the installation of WIN98, WIN2K and XP, please select "Ignore, Terminate, Abandon", but most of these problems are due to the poor quality of the optical disc or the use time of the optical drive. Too long, the disk reading performance is reduced, and at the same time, the optical drive light flashes slowly, accompanied by intermittent "disk" sounds during disk reading.

If we encounter this problem in the process of repairing the computer failure, it is best to directly replace the memory test to see if the same failure still occurs. If the fault disappears, it means that there is a problem with the original memory; if the fault persists, most of it is caused by the poor quality of the optical disc or the decline of the optical drive reading disc, or the system installation file on the hard disk may be damaged.
Fourth, the memory short circuit causes the host to fail to power on

In this case, the memory is severely damaged, but the surface of the memory chip, the golden fingers and the resistive capacitance do not necessarily have obvious burning marks, and sometimes they are exactly the same as a good memory stick. However, after inserting this memory into the motherboard, the motherboard cannot be powered on. After inserting the power supply into the power plug and pressing the power switch, the host has no response, the CPU fan and the power supply fan are not working, and the power indicator is not on, exactly the same as when no power is applied.

Fault identification is also very simple, using the exclusion method and the minimum system method. If a host computer encounters this kind of failure phenomenon, the first step is to eliminate the power failure. If you have other normal power supplies in your hand, it is best to replace them directly. If not, you can remove the power supply, directly short the green and black wires with the wire, observe whether the power supply fan is working, and listen carefully with your ears for any squeaking noise inside the power supply. If there is a problem with the power supply, the quality is unstable and needs to be replaced. The second step is to remove all the sound card, modem, hard disk, optical drive, floppy drive, graphics card, memory, and CPU, leaving only the CPU fan, and then inserting the debug card (if not, you need to observe whether the CPU fan and power fan are turning), and start Power on the motherboard, observe whether the indicator light and digital tube of the DEBUG card have instructions; then insert the CPU and power on the test machine; then insert the memory and add other components step by step. If the above symptoms occur when a part arrives, it means that the part is defective and needs to be replaced or repaired. This method is also applicable to rule out that the system starts slowly and freezes.
V. Memory corruption causes the system to run erratically, blue screens often appear or the system cannot be installed normally and smoothly, and there are always irregular prompts for file reading or decompression errors.

For such problems, software problems should be ruled out first. The first step is to backup the important data of the C drive, and then use the "Format C: / u / c / s" command to forcibly and completely format the C drive, and carefully observe the formatting process. Whether there are bad sectors. Because bad sectors of the hard disk can damage system files, causing the system to run erratically and easily crash. The second step is to reinstall the operating system, and pay attention to whether there are errors such as files that cannot be opened and files not found during the installation process. If not, it basically means that there is no problem with the hardware. The system is unstable and easy to crash. It is likely that the system has been used for a long time and the disk scanning and defragmentation have not been performed regularly, resulting in excessive loss or damage to the system files, resulting in the system. Does not work properly and stably. If a blue screen appears during the installation process, you need to use the exclusion method to replace the memory and CPU. When the fault persists after replacing the CPU and memory, then the motherboard must be replaced for inspection.

Note: Some optical disk drives have very good disk reading performance. After two or three years of use, they are still "high-speed" high-speed disk reading, but at this time, due to the decrease in error correction rate, the optical disk drive reads too many erroneous data. If these data are used to play a VCD, it will not have a particularly large impact, but the data read by this type of optical drive for installing the system will most likely produce similar errors as above, and report that the file cannot be found or decompressed. Occasionally the installation is successful, and "illegal operations" often occur, and the system is very unstable. This kind of failure is more difficult to judge, it will be judged as a memory and CPU problem, and it takes a lot of repair time.
7. Memory corruption causes the system to fail to run normally after startup, and automatically shuts down when it enters the desktop

This problem also needs to be solved by the fifth category of troubleshooting methods.

Tip: Because of the problem of WIN98 system, the operating system is easily damaged. If we change the directory name of C: \ WINDOWS \ FONTS to other letters, then when you restart the system, the system will automatically shut down when it enters the desktop after the blue sky and white clouds appear. The solution is also very simple, press and hold "CRTL" to enter the DOS state during startup, and use the REN command to change the directory name to "FONTS". If the system is artificially damaged, it will cost computer maintenance staff a lot of trouble and waste a lot of time, so as a computer service staff, you should also understand some operating system startup principles and main documents.

Eight, memory corruption leads to optical drive crazy reading

I have encountered this kind of problem twice, and both have exactly the same performance. As soon as the computer is turned on, after the self-test, when the system is about to enter, the CD-ROM drive starts to rotate at a high speed. Even if you do nt put it in the disc, it still turns, which is scary. There was no error message during the self-test, but the fault disappeared after replacing the memory with the replacement method. Put the faulty memory on another machine (the motherboard is not the same), and it will alarm when it is turned on.
