What about memory alarms?

Memory is one of the most vulnerable parts of the computer, if the chassis power supply after the chassis speaker repeatedly alarm or the computer can not pass self-test, most of the fault from memory. And in a variety of memory failures, basically is the memory of the main burning, then we tend to burn the memory left side and directly replace the memory bar.

Memory alarm fault is more common, mainly due to poor memory contact. For example, the memory strips are not standard, the memory strip is a bit thin, when the memory is inserted into the memory slot, leaving a certain gap; the gold finger of the memory strip process is poor, gold finger surface gold-plated bad, time a long, gold finger surface of the oxide layer gradually thickened, resulting in poor memory contact; The memory slot quality is inferior, The reed touches the golden finger of the memory bar and so on.

One, the memory gold finger oxidation rust caused the machine can not start

Failure performance: After opening the chassis power supply, the machine appears for a long time to the alarm, not normal access to the operating system.

Troubleshooting: There are several obvious rust spots on the golden finger of memory found in the check. With the eraser carefully wipe the rust, and the memory of the four slots carefully scrubbed, after the completion of the memory into any one slot, press the power button on the chassis, with a crisp "drip" sound, Machine under normal boot.

Summary: Because the Golden Finger gold plating process is not good or often plug in memory, resulting in the use of memory in the process because of contact with the air and oxidation rust, and gradually contact with the memory slot bad, and finally generate the boot does not start the alarm fault. In addition, because we do not pay attention to inserting the memory, the hands of direct contact with the memory of the golden finger, so that the sweat on the hands attached to the gold finger, so that the place to take more easily caused by the gold finger oxidation rust. In addition, if the hands of direct contact with the memory of the gold fingers, the body of electrostatic very likely to the memory of the particles or capacitance breakdown, leading to memory scrap, so in any case must not touch the memory of the gold fingers, to prevent accidents.

Memory insertion does not completely cause the gold finger on the memory strip to burn

Failure performance: In a chassis "cleaning" after the machine can no longer start normally, to the memory of the gold fingers with the eraser carefully wipe, and replace the memory slot for testing, but still failed.

Troubleshooting: Another memory to insert into the computer, after the boot smoothly into the operating system. Depending on how the slot was previously pulled out of the memory strip, it was determined that the memory's gold fingers were burned after it was turned on because the memory was not fully plugged into the slot.

Summary: In fact, this situation often occurs, as long as the computer repair I am afraid to have encountered similar plug-memory burning things. In general, the burning of the memory strips is mostly due to the fact that during the long period of troubleshooting, the spirit is not concentrated, in the repeated boot test process is not intended to plug the memory or the memory strips are not fully plugged into the slot, or perhaps live plug in memory, resulting in the memory of the gold fingers due to local large current discharge and burned.

Only a very small number of memory strips are in normal use, because of accidental overvoltage or power damage, resulting in memory strips and motherboard damage.

However, the memory strip back to the burn is not necessarily scrapped, most still can be used normally, this is because the memory has a number of power and ground, the reverse plug is often because of the local ground power is connected to the ground, so as long as the electricity will be the short-circuit effect of the ground burned, and other ground and chip has not been destroyed. Although there are two golden hands to guide the feet burned off, but the memory is still able to use the normal, this is the standard "see Luck."
