It is well known that any electrical appliances, in which there were faults, you must take the service center for diagnosis and repair.This is particularly important when it comes to electronic products.However, many of our citizens believe that they can and do cope with failure, even without proper education.The ability to reason, whether it is right or not, leave the philosophers.Surprisingly, in some cases, this independent "repair" allows you to recover.And with respect to computer technology, one learns, for example, how to check motherboard repair.
motherboard is the basis for connecting all the components together.Any damage it could have the most dire consequences, so it is important to know how to check on the performance of the motherboard.Especially when it comes to adart.
buying new components, it is important to carefully check them.While discovering the problem at home, the component can be easily replaced, however, lose its time to re-visit the store - a dubious pleasure.The buyer typically does not know how to check the motherboard, which is only removed from the box.Indeed, the likelihood that the new board would be faulty, it is very small.Yet, in the warranty card is not in vain there is a line that the goods received no damage.The new board must be very carefully inspect for scratches.There were precedents when due unnoticed when buying deep scratches service centers refused to perform warranty repairs.
Usually on the forums asking how to check motherboard usedIn this case, a simple inspection is necessary.First of all, you need to inspect it for scratches, especially deep.
common problem of old boards are swollen capacitors.Currently, classical electrolytic capacitors on motherboards used less, replaced by long-life solid-state counterparts, but a few years ago it was different.The capacitors look like small cylinders soldered to the board.Any swollen, especially with traces of water stains, it ensures that the board has been operating for a long time, although it can be replaced in the workshop.
How to check the motherboard yet?Local darkening light PCB indirect evidence of excessive heat in these places.Sometimes, the reason lies in the heating elements, such as field-effect transistors (mosfetah), which is a valid mode of operation.At the same time, the presence of darkening due to heating suggests that the board is actively used, reducing their useful life.The acquisition of this motherboard - the lottery.
After inspection proceed to the verification program.The main tool - a memory test «Memtest86».It is necessary to burn a CD or flash drive to download images and test memory.Since errors can be detected as a memory (in this case, it is optional), and a memory controller.
Dove computer to work for half an hour with no load "heavy" programs, you need to turn it off and check the temperature of the chipset (the largest chips, often hidden in small radiators).Molten heat sink - a reason to refuse purchase (especially if the contact is a good radiator with a chip).
install the operating system Windows, you must run the test «S & amp; M».Will be tested as the line power supply and motherboard.The modern analogue of this test - OCCT.Passed the test without errors is a good sign.
You can also run the archiver WinRAR, which select the "Benchmark".Errors should not be.
Following these guidelines increases the chance to get a workable fee.It is obvious that every buyer should know how to check the motherboard.
