【 Weak current College 】 memory fault analysis

First, the most common fault: memory corruption, causing the alarm power on memory

This fault we most frequently encountered, is also good for the night before, the next morning a boot, hear not the usual "clicking" sound, but "di, di, di ..." going on, the monitor does not display the image. This failure is most of the time because the computer being used is not good, humidity, in a long time, the memory surface oxidation of Goldfinger, causing memory Goldfinger and memory slot, contact resistance increase, thereby impeding current through memory post error. Represents a post on the "tick tick" going on, we commonly referred to as "memory alarm".

Processing method is also very simple, that is, remove the memory, use the eraser to memory both gold finger carefully scrubbed clean, then plug it back into the memory slot.

Note: when the scrub Goldfinger, must not come into direct contact with the hands, because gold finger hand sweat will stuck in Goldfinger, in use for some time will again result in Goldfinger oxidation, repeated the same failure.

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

1, memory and motherboard compatibility is not good

The memory in another motherboard, long-running stable and reliable; the other memory fault motherboard also run reliable and stable, no warning appears. But put the two together, it appears the "Ding Ding" alarm sound. Such failures could only replace the memory to solve.

2, motherboard, memory slot and poor quality

To replace the multiple brand memory are "filled with the sounds of" alarm sound, occasionally there is a memory is not alarming, but may shutdown reboot will alarm. Such failures occurred mainly in three hundred dollars of low-grade motherboard, motherboard price low, the use of poor quality memory slot, you can only replace the motherboard.

3, a memory chip failure

Such failures are relatively serious, when you post to the host to find memory errors, not to post, send "di di" alarm sound, prompt the user to check the memory. This failure to put the memory on a different host, check for the same "di" beep "sound". If so, you can determine whether a problem is memory; if not, they may belong to the above item 1 or 2.

4, other failures caused by memory alerts

Such failure is not common, it is possible that your motherboard or CPU failure, caused memory alarm, can only be used as a process of replacing them one by one.
Second, the common fault 1: memory corruption causes the system often reported registry errors

Such a failure of the more common, behave as normal boot system, but to get to the desktop, the system will prompt the registry read errors, you need to restart the computer to fix the error, but after you start the computer again, still the same failure. For this type of problem, we can enter safe mode, running type "MSCONFIG" command "start" in front of "ScanRegistry V" to remove, and then restart the computer. If the troubleshooting, illustrates the problem really is caused by a registry error; if the fault persists, basically you can conclude that the machines memory problems, need to use the Replace method to replace performance good memory test for the existence of the same fault.

Sometimes, a long time without disk defragmentation, no error checking, you can also generate system errors and tips registry errors, but for this type of problem in prohibit running "ScanRegistry", the system can function properly, but the speed will slow down significantly. For this type of problem, the solution is the best way is to back up your important data, and then reinstall WIN98.

III. common breakdown 2: memory corruption causes the prompt for installing the system "error when extracting files to correct unlocking a file"

Such failures are common in the installation system, it will often unexpected quit the installation. In practice this is often because the memory of bad quality or poor stability, most of the questions in the troubleshooting change memory. This type of problem either directly from CD or install from a hard disk will appear the same. Although a bit similar to we install WIN98, WIN2K and XP process encountered does not read a file, select the "ignore", termination, give up, but that kind of problem are mostly because of the poor quality of the disc or drive time too long, reading disk performance, and also has an optical drive lights flash, and slowly along with the continuous reading of the liquidation of "give".

If we in the maintenance of computer failures encountered this problem, it is best to directly replace the memory test to see if it still appears the same failure. Such as fault disappears, there is a problem with the original memory; if the fault persists, mostly because of the poor quality of the CD or DVD drive to read disc drop caused by, or on your hard disk to install the system files are corrupted.

Fourth, the memory causing the host to short circuit power

This memory corruption more serious, but the memory chip surface, Goldfinger, RC is not necessarily evident traces of burning, and sometimes and a good memory note. However will this memory plugged into the motherboard, motherboard will not power up. When the power supply into an electrical plug, press the power switch, the host without any response, the CPU fan and power supply fan is not working, the power led is not lit, and no power is the same.

Fault discriminant is also very simple, using a process of elimination and minimum system method. If you encounter a host is the symptom of this class, the first step is to exclude the power failure, if you have other normal power supply, direct replacement. If not, you can remove the power supply, with conductor short-circuit the green line and the black line, the observation of the power supply fan is working with the ears listen carefully to the internal power supply for squeaky noise. If you have a problem with the power supply, the described quality, to be replaced.The second step is the sound card, Modem, hard drives, optical drives, floppy drives, video cards, memory, and CPU are all removed, leaving only the CPU fan, then insert DEBUG card (if not, the need to observe the CPU fan and power supply fan is running) on the system board power to observe the LEDs and DEBUG card digital tube are there instructions; and then insert the CPU, power-on-computer; then insert memory, step by step adding other parts. If a part is the symptom, it shows that there is a problem with the part, you need to replace or repair. This method for troubleshooting system starts slow, panic, and so also applies.

Fifth, the memory corruption causes system instability, often a blue screen or does not successfully installed the system, no law of prompt file to read or extract the errors

For this type of problem, you first should exclude software problems. The first step, first on the c drive to backup important data, and then use the "FormatC:/u/c/s" command on the c drive to force a completely formatted, and carefully observe the formatting process, whether to format the hard drive smoothly, for bad road. Because hard disk bad road makes the system file is corrupted, causing system instability, easy panic. The second step, reinstall the operating system, and observing during the installation process if the file cannot be opened, the file is not found, error. If not, you're essentially describes the hardware, system instability, easy panic, is most likely that the system of prolonged use, there is no regular disk scanning and defragmentation, causing excessive system file is missing or damaged, which causes the system to fail in stable employment. If in a blue screen during the installation, you need to use a process of elimination, to replace the memory and CPU. To replace the CPU and memory, the fault persists after that inspection must replace the motherboard.

Description: some CD-ROM read disk performance is very good, in the use of two or three years, or "whining" speed reading, but at this point because the correction rate of decline, the optical drive into the error data. These data if it is used to play VCD, it will not produce special effects, but this type of optical drive is read into the data used for the installation system will most probably appear above similar error report file is not found or extract error, even if sometimes the installation was successful, and often appear "illegal operation", the system is very unstable. Such fault harder to judge, will be judging for memory and CPU, but many repair time delay

Sixth, the memory corruption causes the system startup is not working, fast access to desktop to automatically shut down when

This issue also needs a fifth class failure of elimination to resolve it.

Tip: because WIN98 system itself, the operating system is vulnerable. If we put the C:/WINDOWS/FONTS directory name changed to other letters, when you restart the system, the system will appear blue sky and white clouds, fast access to desktop to automatically shut down. The solution is simple, start down the "CRTL" to a DOS condition, use the REN command to set the directory name to "FONTS". If you are man-made destruction system, that will make your computer maintenance staff a lot of trouble, wasting a lot of time, as the computer's service personnel should be aware of some of the operating system's startup principles and key files.

7. memory corruption cause the drive to read mad

Such problems I met two times, are exactly the same. As soon as you power on, self-test, fast access to the system, the CD-ROM drive to begin the "whining" high-speed rotation. Even if you don't put in the disc it and go, very scary. In the post process nor is there any error messages, but use the Replace method to replace the memory fault disappears. The fault memory on another machine (not the motherboard), power-on patterning "di" of the police.
