What Is Memory Corruption?

Memory failure is a common failure of computer hardware, mainly for the following reasons: 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. Replaceable memory or motherboard to solve. 2. The quality of the memory slot 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 type of failure mainly occurs on low-end motherboards, because the memory sockets on the motherboard are of poor quality and can only be replaced by replacing the motherboard. 3. A memory chip is faulty. This kind of failure is relatively serious. The host can find an error defect in the memory during the power-on self-test, and cannot pass the self-test to issue a "beep" alarm. 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 concluded that there is a memory problem; if not, it may be the first or second reason above.

Computer memory failure

1. Poor memory quality causes Windows installation error

Symptom: a new one

The fault manifested as a few long alarm sounds after turning on the machine, and no display on the screen. I opened the case and found a lot of dust near the CPU and memory. I think it must be the cause of these dusts. The author skillfully dusted the computer with a small brush and a skin tiger, unplugged the memory, cleaned the dust from the memory surface and memory slots, and wiped the memory gold fingers. Install the memory and restart. ^[2]

After turning on the machine, the machine started normally. I thought the problem was solved so easily, I took a sigh of relief and was ready to check other computers. But at this time, the machine actually restarted with a bang. I am very puzzled, what is going on? Looking at the startup screen of the Windows 98 system displayed by the computer, and observing the scroll bar under the startup screen, about two minutes later, the computer stayed in the startup screen state. Pressing the NumLock indicator did not respond, and the machine actually crashed again. . I think, is there a problem with the system files? Then, I habitually cold-started the computer, started the computer and held down the Ctrl key, and selected "safe mode" in the boot menu, and the system entered the safe mode normally. I think the system can enter safe mode, then there should be no problems with the hardware, most likely it is a problem with the system files. ^[2]

RAM

Take out the Ghost disc for this machine from the CD package, start the computer, quickly format all the hard disk partitions, and use Ghost to recover the C drive again. The cloning process went smoothly, and it only took more than three minutes to complete the cloning. The system booted from the hard disk. I thought it would surely enter the system this time. What is going on? There has never been a crash immediately after cloning. This clone disk is tailor-made for this batch of computers, and no system error can occur. ^[2]

There is really no way, I tried to restart and hold down the Ctrl key, select and enter "safe mode" again. I just picked up the mouse and moved it, but the display suddenly became blank, and many colored horizontal lines were dragged wherever the mouse went. When I saw this situation, I presumed that it was probably because I did nt clean the dust just now. Take the graphics card down for cleaning, so that the graphics card starts to "tangle". So, I turned off the computer, opened the case again, removed the graphics card, carefully cleaned the AGP slot with a small brush, cleaned the graphics card and gold fingers, reinstalled and turned it on. ^[2]

The machine started again with a humming sound, but I still dare not relax and see if I can enter the Windows system normally this time. Sure enough, the worry happened again: the computer showed the Windows 98 startup screen not long after it crashed again. This time, I had to reconsider the cause of the failure. It stands to reason that the machine can pass the self-test and enter the safe mode of the system. There should be no major problems with the hardware, and the software is a new system that has just been cloned. Why can't it still enter the system normally? At this moment, the author suddenly thought: the display Huaping only occurs after entering the Windows system, then the possibility of damage to the graphics card should be small, and in this case, the memory and the motherboard are the biggest "suspicious elements". This machine can't even access the Windows operating system, which is enough to indicate that the memory or the motherboard may be damaged. ^[2]

So, starting with replacing the memory, the author unplugged the machine's memory and removed a 128MB memory of the same model from another machine for replacement. Unexpectedly, the machine successfully entered the system and ran a few commonly used There are no problems with the teaching software. It turned out that the entire failure was actually the fault of that memory. ^[2]

This failure can be judged as a failure of a memory chip on the memory module, which can't enter the Windows system normally and cause the display to be garbled. If repairs are required, be sure to detect the failed memory chip before replacing it. ^[2]
