How to check the motherboard for performance?

Everyone is well aware that any electrical appliances, in the work of which there were failures, it is necessary to hand over to the service centers for diagnosis and repair. This is especially important when it comes to an electronic product. However, many citizens of our country believe that they can cope with the malfunction themselves, even without adequate education. The ability to reason, whether it is right or not, is left to the philosophers. Surprisingly, in some cases, such an independent "repair" allows you to restore working capacity. And as applied to computer technology, a person learns, for example, how to check the motherboard for serviceability.

The motherboard is the basis, connecting all the components together. Any damage to it can have the most unfortunate consequences, so it is so important to know how to check the motherboard for operability. Especially when it comes to used. Techniques.

Buying new components, it is important to carefully check them. While finding a malfunction at home, the component can be easily replaced, however, losing your time on a re-trip to the store is a dubious pleasure. The buyer usually does not know how to check the motherboard that has just been removed from the box. Indeed, the probability that a new board will be faulty is very small. Nevertheless, the guarantee sheet does not for nothing have a line that the goods are accepted without damage. A new fee should be carefully examined for scratches. There were precedents when, because of the unnoticed purchase of a deep scratch, the service centers refused to perform warranty repairs.

Usually on forums are interested in how to check the motherboard used. In this case, a simple inspection is indispensable. First of all, you need to inspect it for scratches, especially deep ones.

The frequent problem with old boards is the swollen capacitors. At the present time, classical electrolytic capacitors on motherboards are used less and less, giving way to long-lived solid-state analogs, but a few years ago everything was different. Capacitors look like small cylinders soldered to the board. Any bloated, and especially with traces of streaks, ensures that the board will not work for a long time, although it can be replaced in the workshop.

How to check the motherboard yet? Local darkening of light textolite indirectly indicates excessive heating in these places. Sometimes the reason lies in the heating elements, for example, field-effect transistors (mosfets), which is an acceptable mode of operation. At the same time, the presence of darkening due to heating suggests that the board was actively used, reducing its resource. The acquisition of such a motherboard is a lottery.

After the inspection, they begin a program check. The main tool is the memory test "Memtest86". It is necessary to write a disk or a flash drive with a loadable image and test the memory. So you can identify errors in both memory modules (in this case this is an optional feature) and a memory controller.

After letting the computer run for about half an hour without load with "heavy" programs, it is necessary to turn it off and check the temperature of the chipsets (the largest chips, often hidden by small radiators). The heated radiator is an excuse to refuse to buy (especially if the contact of the radiator with the microchip is good).

Having installed the Windows operating system, you need to run the "S & M" test. Both the power supply line and the board will be tested. The modern analogue of this test is OCCT. Passed without errors, the test is a good sign.

You can also start the WinRAR archiver, in which to select the "Test speed" option. There should be no mistakes.

Following these recommendations increases the chance to get a workable fee. Obviously, every buyer should know how to check the motherboard.
