The host plug power emits an alarm sound

The root cause of the memory alarm causing the computer to not boot is:

1). Memory corruption.

2). The memory slot of the motherboard is damaged.

3). There is a problem with the memory power supply of the motherboard or related circuit.

4. Bad contact between memory and memory slot.

The above 1,2,3 fault is a real hardware failure, we can replace the elimination method, detect the fault components, and then repair or replace the bad parts can be resolved. For the 4th case, we encountered the most, what components are not damaged, is caused by poor contact.

Memory and motherboard Bad contact reasons are:

1). Memory Slot Distortion

This fault is not very common, generally seen in the motherboard visible changes, memory slots are damaged, cracks and other phenomena, when we put the memory into the memory slot will be part of the bad situation, when the host power-on self-test can not pass, there will be a continuous short "tick" sound, which is often said "memory alarm." For motherboard deformation, memory slot deformation of the phenomenon we can be plugged in after the memory through the use of nylon cable fastening, and then supplemented by the method of glue to solve such problems.

However, in the process of unplugging memory, we must pay attention to the direction of memory, while the memory and memory slots are designed to stay in place, there are still a lot of newbies that plug in the memory, causing the memory strips and the memory slots to fuse individually, and then only use the damaged memory slots. For pin-fused memory strips, we can examine them carefully, if only 77 and 85 ground-end fused, or perhaps other memory of the grounding end, even if the gold fingers burned off, such a memory is due to the grounding in the back of the power supply is a short circuit, only to create a spark burned the memory of the gold fingers and memory slot pin , and the memory chip has not been any damage, so we just plug it in the normal memory slot can be used normally.

Sometimes we also have to pay attention to whether there are other foreign objects in memory plug, because if there are other foreign bodies in the memory slot, when the memory can not be inserted into the end, the memory can not be installed in place, of course, will appear on the alarm phenomenon. When we have many times to plug the memory can not solve the problem, it is best to carefully check the memory slot is distorted, whether there is a pin deformation or damage, shedding, slot in the presence of foreign bodies, and so on, it is very helpful to our troubleshooting.

2). Memory Gold Finger oxidation

This situation is most likely to occur, generally seen in the use of half a year or more machines. When the weather is humid or the weather temperature changes, it will appear yesterday machine work is good, can be turned on the next morning that is found not normal boot, monitor black screen, only listen to the machine "tick beep" straight ring.

If only once in a while is not a surprise, just open the chassis and plug the memory bar. However, if this failure occurs once a month or one weeks or half a month, it is necessary to consider is not part of the memory and motherboard compatibility problems, that is, the following 3rd type of problem.

Methods of prevention:

(1). Adopt the Fastening method of the 1th kind of problem to solve;

(2). Then install and overhaul, must not hand directly contact memory slot of the golden finger, because the sweat on our hands will stick to the memory of the gold fingers, if the memory of the gold fingers poor workmanship or no gold plating process, then the memory in the use of the process is very easy to appear gold finger oxidation, A long time will lead to the memory of the memory slot bad contact, the last boot memory alarm. For the memory of the oxidation caused by the power-on alarm, we can not simply reseat the memory, we must carefully use the rubber to the memory of the gold fingers carefully wipe, rub it shiny, and then plug back on it.

(3). There is even if we do not often use the computer, but also every one weeks to do at least boot once, let the machine run one or two hours, using the heat generated by the machine itself to drive the internal moisture away from the machine to maintain a good running state.

3). Memory and motherboard compatibility is not good

This problem is the most difficult to deal with, it is difficult to determine, the fault occurs more frequently, but the test of memory and motherboard are often not found problems, dealing with very troublesome. In the actual work, I encountered the most is the Tepo motherboard and the Mao Si Memory, the two together with the use of a frequent boot memory alarm phenomenon, the plug in memory after the failure disappeared, but not one months will certainly reappear. To completely resolve, only replace other brand memory.
