Memory fault diagnosis and maintenance of

Computer memory is the most prone to failure of accessories one of the products, if the power is in the press box or a computer chassis alarm horn can not be repeated self, in most cases due to memory failure. While in all kinds of memory failures are basically destroyed the main memory, when we tend to lose the memory will be destroyed after a direct replacement in the side of the memory. In all kinds of memory failures are basically destroyed the main memory, when we tend to lose the memory will be destroyed after a direct replacement in the side of the memory. Because of memory compared with other cheaper parts, resulting in a lot of a friend once the machine memory problems detected, but not through any direct replacement of memory processing, resulting in great waste.
As the memory compared with other cheaper parts, resulting in a lot of friends, once detected in the machine memory problems, but not through any direct replacement of memory processing, resulting in a great waste. In fact, in many cases, failure of memory, the future we through the restoration is entirely re-use, followed by the writer's encounter with the two cases of memory failures to do something with you to explore. In fact, in many cases, failure of memory through the rehabilitation of the future we can re-use, followed by the writer's encounter with the two cases of memory failures to do something with you to explore.

Failure Performance: writer friend is a super-computer game enthusiasts, playing games is a master of computer hardware knowledge is not deep. Failure Performance: writer friend is a super-computer game enthusiasts, playing games is a master of computer hardware knowledge is not deep. Not long ago, my friend's computer had a problem: open chassis power long after the machine appears alarm, simply no regular access to the operating system. Not long ago, my friend's computer had a problem: open chassis power long after the machine appears alarm, simply can not normally enter the operating system. So he called for help to the writer. He therefore called for help to the writer. I right friends, this computer is still quite familiar with, which is assembled with a two years ago, Intel Pentium 4 2.4GB PC processor, motherboard uses a 865PE chipset Soltek group, a 256M DDR333 memory, hard drives for the Western Digital WD800BB, Colorful graphics for the R9550, plus a Samsung DVD-ROM. The author of the friend is still quite familiar with this computer, which is assembled with a two years ago, Intel Pentium 4 2.4GB processor-based computer uses a Soltek motherboard 865PE chipset, a 256M DDR333 memory, hard drives for the Western Digital WD800BB , Colorful graphics for the R9550, plus a Samsung DVD-ROM. According to a friend describing the phenomenon, the author concluded that there is a memory problem, so let friends unplug the memory slot give it a try, after a change. According to a friend describing the phenomenon, the author concluded that there is a memory problem, so let friends unplug the memory slot give it a try, after a change.

Troubleshooting: a friend in accordance with the author's method will remove the memory slot, after a change to re-insert after boot soon as crisp as the "drip" sound, problem-solving. Troubleshooting: a friend in accordance with the author's method will remove the memory slot, after a change to re-insert after boot soon as crisp as the "drip" sound, problem-solving. In respect of a few days ago, friends panic open call, said computer problems had emerged, and the previous failure of the same, but this time no matter how hard to replace the memory slots were unable to start correctly, and the motherboard only has four memory slots a month-by-trial times. In respect of the previous few days, friends, panic open call saying the computer problems had emerged, and the previous failure of the same, but this time no matter how hard to replace the memory slots are not start correctly, and only four on the motherboard memory slot has been a month-by-trial times.

So I bring a simple tool to a friend's house, open the chassis, remove the memory of this careful observation, memory PCB board in all components and there have been no signs of any burn-off. So I bring a simple tool to a friend's house, open the chassis, remove the memory of this careful observation, memory PCB board in all components and there have been no signs of any burn-off. However, this writer found during inspections that the memory of gold There are several obvious finger stain, so I brought rubber with these rust spots carefully wipe clean, and the memory of the four slots were careful to clear the whole, when completed, will the memory re-inserted into any one slot , press the POWER button on the chassis, with a loud crisp, the "drip" sound after the machine started normally. However, this writer found during inspections of memory there are several obvious cheat on the stain, so I brought rubber with these rust spots carefully wipe clean, and the memory of the four slots were careful to clear the whole, after the completion memory re - inserted into any one slot, press the POWER button on the chassis, with a loud crisp, the "drip" sound after the machine started normally.

Summary: Because the memory of the finger gold plating poor or frequently swap memory, leading to the memory in the course of oxidation due to contact with air, rust, and gradually with the memory slots being exposed, culminating in the boot does not start the alarm failures. Summary: Because the memory of the finger gold plating poor or frequently swap memory, leading to the memory in the course of oxidation due to contact with air, rust, and gradually with the memory slots being exposed, culminating in the boot does not start the alarm failures. In addition, as we do not pay attention when you insert memory by hand direct contact with the finger memory, so that the hands sweat attached to the finger, so that to take place more easily oxidized rust caused by finger. In addition, as we do not pay attention when you insert memory by hand direct contact with the finger memory, so that the hands sweat attached to the finger, so that to take place more easily oxidized rust caused by finger. In addition, if hand direct contact with the memory of the finger, the body's static electricity is very likely the memory of the particles or capacitor breakdown, leading to the memory scrap, so in any case must not be touched by hand memory, Goldfinger, to prevent accidents. In addition, if direct contact with the memory of the golden finger hand, the body's static electricity is very likely the memory of the particles or capacitor breakdown, leading to the memory scrap, so in any case must not be touched by hand memory, Goldfinger , to prevent the accidents.

2, the memory is not fully inserted lead to burning cheat on memory 2, the memory is not fully inserted lead to burning cheat on memory

Fault performance: a friend this computer through the author's maintenance, it has been no recurrence of any problems. Fault performance: a friend this computer through the author's maintenance, it has been no recurrence of any problems. With the arrival of summer and friends in one of the chassis to "clean" after the machine would no longer be able to start normally, and actually with the previous failure The very similar. With the arrival of summer, and friends in one of the chassis to "clean" after the machine can no longer be able to start normally, and failure actually very similar to the previous. So in accordance with the author as a friend to cheat on memory use rubber carefully polished, and one by one to replace the memory test, it is hilly  quinoa Qiao Mi ridiculed Long  ease their income carbazole bristle ape Radon Astatine Ju Shu? br /> So according to the author as a friend to the memory of the finger wipe carefully with a rubber, and one by one to replace the memory test, it is hilly  quinoa Qiao Mi ridiculed Long  ease their income carbazole bristle ape Radon Astatine Ju Shu?

Troubleshooting: The author's careful examination, found that failures still appear in the memory on this. Troubleshooting: The author's careful examination, found that this failure still appears in the memory. Since no method to deal with a friend repeated tests, it is not other parts are also a problem. Since no method to deal with a friend repeated tests, it is not other parts are also a problem. In order to further determine the origin of failure, the author will bring a portable memory into a friend's computer, boot into the operating system after the successful It seems the memory must be destroyed. In order to further determine the origin of failure, the author will bring a portable memory into a friend's computer, boot into the operating system, a smooth, it seems the memory must be destroyed.

So I carefully asked a friend, in the clear after the whole memory has not completely inserted into the memory slot, the author answered quite vague. So I carefully asked a friend, in the clear after the whole memory has not completely inserted into the memory slot, the author answered quite vague. So I concluded that may be because the memory is not fully inserted into the slot where the golden boot after memory fingers burned. So I concluded that may be because the memory is not fully inserted into the slot where the memory will boot burned finger.

In fact, this situation often occurs, as long as I am afraid, has done a computer repair have encountered a similar anti-insert the memory burn things. In fact, this situation often occurs, as long as I am afraid, has done a computer repair have encountered a similar anti-insert the memory burn things. Normal circumstances, the memory of the burning of most of them because we have a long fault exclusion process, lack of concentration, in the repeated start the testing process did not intend to insert anti-memory or memory is not fully inserted into the slot, but also may be charged-swappable memory, resulting in memory of the finger because of local high-current electrical discharges burned. Under normal circumstances, the memory of the burning of most of them because we have a long troubleshooting process, lack of concentration, in the repeated start the testing process did not intend to insert anti-memory or memory is not fully inserted into the slot, it may be Charged-swappable memory, resulting in memory of the finger because of local high-current discharge and were destroyed.

Only a very small number of memory used in the normal course, since the accidental over-voltage or power supply is damaged, resulting in memory and motherboard and other damage at the same time. Only a very small number of memory used in the normal course, since the accidental over-voltage or power supply is damaged, resulting in memory and motherboard and other damage at the same time.

But memory is not necessarily anti-inserted after the burning of the discarded, and the majority was able to normal use, this is because the memory of how power and ground roots, anti-inserted often is because the local ground to the power and ground are connected to pass, so long as this power-up will be the role of a short-circuit ground wire from burning, while the other ground and the chip has not been destroyed. However, the memory is not necessarily anti-inserted after the burning of the discarded, and the majority was able to normal use, this is because the memory of how power and ground roots, anti-plug, often because of local ground to the power and ground are connected to pass, so long as this power-up will be the role of a short-circuit ground wire from burning, while the other ground and the chip has not been destroyed. above left in the memory, although there are two finger pins were burned off, but the memory can still be used normally and this is the standard "luck" of the Above left in the memory, although there are two finger pins were burned off, but the memory can still be used normally and this is the standard "luck" of the
