Totally Unfunction Motherboard

To second hand computer always be followed by several risk as : In this case we see that computer age is unpredicted . It is often happened the computer was run properly when we bought it , but soon after several of operation the computer has been totally stacked .This is a possibility we will face when we face a second hand computer .

That is the reason we say that it is so hard to predict that our new second hand computer will long live under our hand. The center of the problem is that the second hand mother board some time use several low quality spare parts. So the damage possibility of the second hand tools is so high compared to the qualified one. On the other hand there is another possibility that the second hand computer live time is depended on the user or owner. There are several factors influenced the damages :

1.The power is activated but there is no "On" sign.
2.The power is activated but and power supply is the only can be run
3.The power is activated but there is no beeps sound
4.The power is activated but there is a flash signal

Solution:

First try to clean dust from the interior cashing especially in motherboard part You can cleand the dust by air spraying or soft brush or hair dryer but the treatment must not be followed by heating or you can clean them by alcohol tape head cleaner. Finally try to dry them properly

If the problem is still existed as the result of the cleaning process, or the computer is still unable to make beep sound!.now try to clear your motherboard’s CMOS . If the computer soon produces beep sound as soon as after you took the clean processing, it means there is a running possibility

Of your computer . Some thing you must do is you have to uncover how many beeps sound can be produces by the computer , and try to compare with your computer guidance book.. and you can find the problem of beeps sound signal. In every new motherboard always be provided by jumper for CMOS clearing. If you are successfully can return your old computer by replacing or reversing the battery for 180 degrees do it and let it cool as about 30 seconds.

If all the treatment above does not turn give any solution to your computer problem you can change your Power supply. But if you don’t have any reserve power supply you would better to try the following ways before you decide to buy a new Power supply.
Before you try to remove your motherboard , or if you don’t know the proper position to install the following connector as : speaker , power, reset, HDD – led and everything in your motherboard, it is better you remember the position at first.

For connector installing you can see the tip of the connector , usually we can find three angle symbol., three angle mark is match to (+) symbol in motherboard connector.In several particularly motherboard commonly the written connector face outward of the motherboard.

Put your mother board on the table , then remove the processor and memory also, then turn it on. But you have to ensure that Power Suply and speaker chasing have been installed properly in order to recognize the “on” sign resulted by the beep sound appeared by the motherboard.

Wether the motherboard resulted beeps slund?
If it is so, that is the good signal , because it means that the “on” signal we you are trying to find is appeared. Compare to the mother board guidance book, then you will find the proble. You have to do some actions in order to avoid beeps sound.and the computer can be run as usual.

IF all of the treatment above still find the bottle neck , there is a possibility that your motherboard is damage.

By studying the last case mentioned above as simultaneously blinking power led , and it is not followed by the other "on" signal ,seemly the system is in standby mode. You can try by weak the mother board up by pushing power supply button as long as 45 seconds.

When the treatments above are failed to return your computer, there is a possibility your computer is in damage condition or totally unfuctioned. Usually the cylinder component near the connector is damage.
