Memory slot is damaged. Repair method

There are many manufacturers of memory in the market, and the price is relatively cheap. After a memory failure, we usually choose to replace the new memory module. In fact, in some cases, it is not a problem in the memory itself, but because the quality of the motherboard is not too hard or we often plug and unplug the memory module, causing the memory slot to be deformed and the machine can not start, frequently crash, etc., then The author simply summarizes the memory failures encountered in the computer. Some friends who have encountered the following faults may wish to try them according to the author's method, and may bring you unexpected surprises. Today I will teach you some memory slot damage troubleshooting methods, I hope to help your computer. Step /Method 1, the computer often blue screen of death, the original is the memory slot troubles: a 2000 assembly compatible machine, the specific configuration is as follows: Intel Celeron 1.1GHz processor (370 pins), Kingston 256M DDR266 memory , MSI 815PE motherboard, colorful MX400 graphics card, Seagate 40GB hard drive, Samsung DVD-ROM drive, use has not had any problems. Recently, the author found that after using this computer for a period of time, the machine often has a blue screen and a crash, which causes the computer to not work properly. After the crash, press the power switch again and sometimes it can't start normally. The machine alarms that there is a problem with the memory. After the memory is re-plugged, the machine can start normally, but after a period of use, there will still be a blue screen or a crash, about two hours or so. . The error message on the blue screen screen is “Vxd, Vmm (01) file error & rdquo;. Fault analysis and processing: According to the error message when the blue screen is displayed, it is known that some kind of virtual file in the memory is wrong. In addition, the alarm prompt of the alarm when it cannot be started can accurately judge the memory. At the beginning, the author determined that it may be that the contact was bad, and it was often solved by plugging and unplugging. This is not the way to solve the problem. So the author took the memory stick out of the machine, carefully wiped the gold finger of the memory stick with the plasticine, and carefully checked the small components on the memory, and found that there was not much problem. The fault was not solved after reinserting the machine. ,The problem is still. So the author took a normal use of the memory stick from another machine and inserted it into the faulty machine for testing. After a period of time, the machine crashed and the fault was not solved. It seems that it is not a problem with the memory stick. So carefully check the memory slot on the motherboard, found that the slot into the memory module is a bit deformed, it seems that the problem appears here. So I inserted the memory stick into another slot (because I used to plug the memory into the DIMM1 position, I didn't consider the slot when I solved the problem), I rebooted and played for more than two hours. After the game, the machine works fine and the problem is solved. Second, after upgrading the memory, the computer can not start normally. Symptom: A brand machine with Intel Celeron 1.7GHz, the memory capacity is 256MB DDR333, and the work has been relatively stable. Recently, this machine has been upgraded, and a 256M DDR333 memory of the same model has been installed. After booting, it will encounter a black screen. At this time, the power indicator of the monitor is on, the machine cannot pass the self-test, and the chassis speaker will alarm for a long time, prompting the memory. Unable to pass the self-test. Fault analysis and processing: the chassis speaker prompts the performance, the root cause of the fault is on the inner strip. Because it is a fault after installing a memory stick, the problem should be on the newly added 256MB memory, so the installed 256MB of memory is unplugged (the memory is found to be hot), and then booted, but the fault remains. Is there a problem with the graphics card or the CPU? When using the exclusion method, replace the graphics card and the CPU separately and eliminate them one by one. The problem remains. After removing the CPU, hard disk, memory, and graphics card one by one, it seems that there is a problem with the motherboard. I found a motherboard that can support the Intel Celeron processor for testing. Everything is normal and the computer goes smoothly. Then there is a problem with that part of the motherboard? According to the machine's prompt, the possibility of memory failure is relatively large, is there a problem with the memory slot on the motherboard? So the focus is on the memory slot of the motherboard. on. Through careful and careful inspection, it was found that the 8th and 9th feet in the memory slot were touched together and shorted. Use a small tweezers to gently separate the 8th and 9th feet that touched each other, and then carefully install the memory and other components. After starting the test, I finally saw the long-lost blue sky and white clouds, and troubleshooting. Third, the insertion is not complete, causing the machine to fail to start properly. As the summer approaches, the author has performed a “cleanup” on the computer to clean up the dust inside the chassis and install a new cooling fan. After the end of the cleaning, the author couldn't wait to turn on the computer and check the results of his labor, but he was in trouble. After pressing the power button on the chassis, the machine cannot be started normally. The short alarm sound of the chassis speaker indicates that there is a problem with the memory of the machine. Fault analysis and processing: The two 256M DDR400 memory used by the author's love machine, because the 865PE motherboard supports dual channels, the two channels are built to improve the overall performance of the system. The brand of memory is Kingston. It is reasonable to say that the stability is quite good. I have not used this computer for more than a year. Open the chassis and carefully check the two memories. At this time, I found that the memory is inserted into the DIMM1 and DIMM2 positions because the memory slot of the motherboard is in the position of DIMM1 and DIMM3 or DIMM2 or DIMM4. So this time I didn't work in the dual channel mode, but I can't open it. So I will insert the internal access of the DIMM2 into the slot of the DIMM3, but when I pull out the memory and find that the memory stick is not fully inserted into the memory slot, will it be a fault caused by incomplete insertion? So I am the author The memory will be removed, re-inserted, and carefully checked to make sure that it has been correctly inserted into the memory slot, and then boot test, with a clear "drip" sound, the machine smoothly enters the system, fault exclude. Precautions should be noted that from the above three faults, the memory slot is deformed and damaged. If the memory is not installed, it may cause various abnormal phenomena. Therefore, once we have determined that there is a problem with the memory, we must start from all aspects. , carefully check the source of the fault. Check the slot, replace the memory and other careful tests. Finally, find out the root cause of the problem according to the fault performance, and carefully summarize and solve it. After encountering the problem again, we have the experience and can quickly check and eliminate the memory. Various failures.
