Computer often freezes, bluescreen or inability to normal start,samsung r20 laptop keyboard
start unable to enter the operating system, usually we through the
replacement exclusive method to find the fault of the place, and the
fault is mostly due to the main board, such as graphics hardware
equipment damage caused, of course, because the software Settings or
system encounters the threat of the virus can also cause more trouble.
To
the specific location fault is often very headache, but generally
speaking memory fault is usually the cause of this kind of problem of
maximum causes, including memory damage, not compatible or memory slot
damage etc. That is to say, in judging whether the fault by other
components before had better to eliminate the cause of memory, after
all, this is the greatest possibility. This paper will introduce
detailed memory fault samsung r23 laptop keyboard manifestation of, elimination method and cause the memory essential reason of failure.
A, memory after damage of several performance directly
Memory
after damage calculation opportunity to appear a lot of failure forms,
but if the detailed observation, but can be found that the most common
fault basically has the following kinds of forms:
1,
the machine can't normal start, and with the chassis alarm, the voice
for continuous talking short sound, this is said in BIOS memory fault or
no detection to the memory of the code. In this case, can only take
substitution method to diagnose fault or what is memory on the mainboard
memory related part of the order.
2, install Windows 2000 or XP appear bluescreen, it can direct judgment for memory fault.
3, running Windows or XP often freezes samsung r25 laptop keyboard
or appear bluescreen, pay attention to this kind of circumstance
although memory failure cause, but there are other possible, such as
power supply, heat dissipation and even virus, etc.
4,
operation memory high correlation program or software frequently
freezes, the software such as 3 d games, test procedures, Photoshop,
etc. Another screen display deformation, the system in use short a
period of time will crash of the operation of the system, large game
crash, etc, basically can be judged by the memory is caused by the
failure.
Second, the origin of memory fault judgment
Although the above problems in most cases is caused by samsung r25e laptop keyboard
memory fault, but in order to further judgment, we can use substitution
method on each side. In addition can also through some memory test
software to check the origin of fault. Once regarded as memory fault
(note here said memory fault including memory own fault also includes
some case motherboard corresponding part of the memory fault), the next
step is to do more accurately determine the fault components. We can
through the following methods to find the real cause of the fault
memory:
1, if your system only inside a memory, so
simple solution is the "memory a slot, to test the. Because the memory
slot fault especially memory slot and memory module of transfer between
the fault can also cause the same test results. If the test appeared in
the same mistake, then memory module has a problem and the possibility
of a lot samsung r26 laptop keyboard.
In order to more accurately confirm, can this memory to a piece of
running good on the mainboard to do a test. If the problem is still, can
replace the new memory bank.
2, if your system has
more memory, the next step is to find out the problem which memory. Of
course, if you have recently upgrade of memory or added a memory, then
maybe judgment is very simple, the problem may be out of memory or the
new added new add memory in the slot, the relatively good judgment some.
For general condition that the recent memory and no changes, to find
out the fault by the only test, namely to keep only a memory, will other
pulled out, running test program, and then in the same slot on other
memory bank also do the same test. If the test is only a memory failure,
so, the cause of the samsung r26s laptop keyboard
problem was found. If test each memory all appear the same mistake
report, the biggest may is the slot has a problem, of course, also
cannot rule out all the memory bank has the possibility of failure, it
will need to change a slot or changing motherboards the test.
For
multiple memory there's still another possibility, namely a single
tests are no problem, but when put all the memory on on test program is
an error, and this may have two reasons: 1, the compatibility between
memory is bad, can't work together; 2, more may be motherboard memory
slots in a has a problem, in this case can respectively by the with a
memory in the memory slot on running test, in order to find out the
existing fault memory slot.
Three, lead to memory the root cause of the failure
And within the PC compared to other accessories, samsung r29 laptop keyboard
memory structure and produce relatively simple, its but the grain
storage chip through the simple circuit together, and memory chip
(DRAMchips) before they leave the factory in general also all passes
through the strict test, therefore the failure probability relative to
less than other parts. However, any one electron device in the work and
use process for some factors are fragile, memory is no exception:
Voltage: mains voltage big fluctuations, or PC samsung r45 laptop keyboard
use inferior power, also can give memory damage, and sometimes such
damage may be immediately appear, and some case is can be long-term,
gradually reduce the memory of the electrical index. In addition,
long-term memory using pressure overclocking method also can damage the
memory.
Electrostatic: static electricity is lead to
memory module damaged the main factors. Therefore, in we installed or
unloading memory module, if there are conditions can use wrist strap,
otherwise, the contact before memory module should take a certain means
on electrostatic dispersed, such as touching the ground metal products
like samsung r463 laptop keyboard
heating pipe and so on. In addition, in the contact memory module
greatly too forcibly knead don't lead to bad memory chip or peripheral
circuit, do not think this is kidding, the author had more than once
seen users in the pull plug memory will memory module on the small
voltage touch off situation.
Working environment: if
your PC case filled with dust, or PC working environment relative
moisture, so, long-term working in this kind of environment factors, the
life of the memory module will be greatly reduced. In addition, if your
PC samsung r465 laptop keyboard
cooling bad word, memory long-term work under high temperature, no
matter the corresponding heat is by the memory module or surrounding
parts have, also can shorten its life.
Motherboard
memory slot and memory peripheral circuit: normally doesn't belong to us
today to discuss memory damaged category, however, motherboard memory
slot in the strong pull seating can also damage, and on the mainboard
circuit is samsung r467 laptop keyboard
also due to the above-mentioned factors and damage, but most of the
time this kind of circumstance symptoms and memory module damage
symptoms it is difficult to distinguish, can only take substitution
method to diagnose.
