How to check your motherboard for performance

Computer motherboard is a link of all its components. Usually users highlight the video card and the processor as the most important components, but without a reliable motherboard, they will not work either simply burn. Checking the motherboard takes place in three stages: visual inspection of the component, connection of the power supply, the power on and the local sequential disconnection of the components. According to statistics, more than 90% of all breakdowns of the motherboard lie on the user’s shoulders, as it almost does not break down by itself. Remember, you may have broken tea to the system unit, playing in too high graphics settings either one of your details recently burned. Inspect your motherboard, according to the instructions below.

This stage is the most important: you can identify malfunctions in the motherboard even before installation in the system unit, especially if it is a motherboard purchased from hand. Do not forget that the installation of a faulty component can lead to breakage of all other elements of the system unit.

Diagnostics of HDD and SSD disk.

Disc diagnostics make in two directions check the SMART system of a hard or solid-state disk and check the disk directly to be broken or slow sectors in order to check the Smart HDD and SSD, we will use the Crystal Disk Info program. You can download it from our site in the Download section.

Now let’s go directly in the diagnostics of the disks, after downloading the program, we start the file of the desired bitency and look at the main window if you see the blue-color signature icon well or in English good means with your smart disk, everything is in order and further diagnostics can not be carried out.

check, computer, motherboard

If you see a yellow or red icon with inscriptions carefully, bad, it means that your disk have any problems. You can learn about the exact problem below in the list of the main diagnostic elements SMART. Everywhere where will be yellow and red icons opposite the inscription, it will say that your disk suffered in this part.

If you have already exhausted the disk resource, then it is not worth repairing it. If you have found several broken sectors, the possibility of repair still has. On the repair of broken sectors, I will tell further. If there is a lot of broken sectors on the disk, more than 10 or many very slow sectors then restore such a disk. After some time, he will still fall further, it will need to constantly restore / repair.

Disk software repair.

Under repair, I mean the removal of broken and slow sectors on the disk. This instruction is suitable for HDD discs, that is, only hard drive. For SSD, this operation will not help anything, but only worsen the state of the solid-state disk.

Repair will help some more extend life hard to your disk. To restore broken sectors, we will use the HDD Regenerator program. Download and run this program, wait until the program will collect data about your disks after the data will be collected. You will see the window in which you will need to click on the inscription. Click Here to Bad sectors on Demaget Drive Surfase Directly Under Windows XP, Vista, 7, 8 and 10. Click on the inscription you need to quickly in OS 8 and 10, so the window quickly disappears, in 7 everything is fine. Next click No. Then in the list choose your disk. Press Start Process button. A window will appear as a command line in which you will need to press 2, ENTER, 1, ENTER.

After the operations proceeded, the system will begin to scan the system for the presence of broken sectors and moving them on non-readable disk partitions. In fact, broken sectors do not disappear but in the future they do not interfere with the operation of the system and you can continue to use the disk further. The process of checking and restoring a disk may take a long time depends on the volume of your disk. After completing the program, press the 5 and ENTER button. If you have any errors during testing and correction of broken sectors, it means that your disk is not possible. If you have been found more than 10 bands. broken sectors, then restores such a disc does not make sense, there will be constantly problems with it.

The main signs of the failure of the disks is:

  • Slow operation of opening files and programs.
  • Dusty reboot of a computer.
  • Large load on the processor.
  • Departures to Blue Screen.
  • Monteneer hangs.
  • There may be other problems but telling everything is not possible.

We will further check the RAM (RAM)

Check motherboard battery

First thing after cleaning, then not to forget, I check the battery charge on the motherboard, and at the same time I discard BIOS. In order to pull it out, you need to press a flat screwdriver on the latch in the direction indicated in the photo and it will pop up.

After that, it is necessary to measure its voltage by a multimeter, optimal if it is within 2.5-3 B. Initial battery voltage 3 in.

If the battery voltage is below 2.5 V, then it is desirable to change it. Voltage 2 V is critically low and PC is already starting to collect, which is manifested in resetting BIOS settings and stops at the beginning of the PC load with a proposal to press F1 or some other key to continue download.

If you do not have a multimeter, you can take a battery with you to the store and ask you to check or just buy a battery in advance for replacement, it is standard and completely inexpensive.

The explicit sign of the Sex Battery is the constantly moving date and time on the computer.

The battery needs to be changed in a timely manner, but if you don’t have no replacement at hand, simply do not disconnect the system unit from the power until you change the battery. In this case, the settings should not fly, but problems may still occur, so do not tighten.

Battery Check Good Time for BIOS Full Reset. At the same time, not only the BIOS settings are reset, which can be done through the Setup menu, but also the so-called energy-dependent CMOS memory, in which the parameters of all devices (processor, memory, video card, and t.D.).

CMOS errors are often the causes of the following problems:

I remind that before resetting the BIOS, the system unit must be disconnected from the outlet, otherwise the CMOS will be filled with BP and nothing will happen.

To reset BIOS for 10 seconds, close the contacts or other metal items in the battery connector, this is usually enough to discharge capacitors and complete CMOS cleaning.

A sign that the reset happened will be a confused date and time to be installed in the BIOS with the nearest computer loading.

Use multimeter when diagnosing PC

Initially, I will immediately make a reservation. The article is not for the pro, but for beginners of master-computer, and for those who independently want to find the causes of malfunction in computer equipment, but at the same time not possess wide knowledge in the field of electricians, electronics. Information exclusively for amateur experiments.

One of the items of the list of measures produced in the prevention of system blocks of PC and laptops is visual and tactile diagnostics (on the subject of swollen capacitors and highly heating computer elements). In this article, the reader offers several simple ways of instrumental diagnostics using an electronic multimeter.

Theory: Multimeter, Device, Safety.

Multimeter. Universal Multipurpose Device for the production of various measurements and measure the current values ​​in electrical circuits. This device in its classic design allows you to measure: voltage in electrical circuits and nutrition elements, current strength, conductor resistance, diagnose various radio elements (transistors, resistors, capacitors, diodes). professional models allow measurement of capacitors, measuring the temperature of various surfaces, generate electrical impulses.

Next, the article will be discussed about the simplest multimeter of the M-83 type (DT-832), which can be purchased at any economic store, Radiorenka or in the tool stores (sometimes in construction). This is the most popular type of multimeters, since it has the most necessary features, easy to use and inexpensive.

M-83 multimeter (DT-832) is a compact () electronic device, measuring about 12×6 cm with two senses (measuring contacts).

To turn on the device, it is enough to rotate the switch located in the center of the device to one of the positions separated by the sector on the sectors (see the desired one):

  • DCV. voltage measurement in DC circuit
  • DCA. current measurement in DC circuit
  • ACV. voltage measurement in alternating current circuit
  • Ω. measuring resistance
  • Volume and Diode Sign. Sound “Circuit” Chain
  • OFF. Turning off the multimeter

To connect probe, there are three sockets:

  • COM is always used only for connecting black probe (black dipstick is minus, land); It is fundamentally no meaning to connect to COM, however, to avoid confusion during measurements, electricians in practice agreed: “Black. always minus, for him a COM-nest”
  • VΩma. for red probe when measuring DC readings
  • 10ADC. to measure voltage in the AC network of high-voltage lines (red)
  • The digital multimeter is an electronic device that runs from the battery (Croon type 9V 9V 9V). Before use, make sure that the battery does not discharge; To do this, move the switch to any position and pay attention to the clarity and saturation of the display; The device with the “Sex” battery can not be used
  • Never turn on the device and do not measure with wet hands or standing on the wet surface with barefoot legs
  • Before using the Multimeter, inspect it, determine the appearance of its condition and integrity of the case, display, switch, probe conductors, if the device has significant mechanical damage, insulation disorder, contact breaks and other disadvantages. it is impossible to use it
  • The device is not intended to measure readings in networks and voltage circuits Over 500V
  • Make measurements touching contacts only by the arrivals of the multimeter, avoid touches of conductors with your fingers or other bare parts of the body; When measurements in the 220V network, contacts can cause injury or lead to death

PC diagnostics using multimeter

I offer three simple, available and absolutely safe methods for checking individual nodes and computer elements:

The most elementary method for checking the integrity of the conductors. “Svetonka”. Using a multimeter, you can check, for example, a system unit power cable, VGA- and LPT cables. This can be done in two ways: using the multimeter display and using the sound indicator built into the device (“Food”).

  • Connect the black probe into the COM nest, red. in the jack VΩma
  • Set the instrument switch to position Ω = 200
  • Connect any of the probe to any of the cable contacts
  • Touch the second probe symmetrically located contact on the other end of the cable
  • In the presence of contact at the ends of the conductor (in the absence of a break), the instrument’s readings change chaotically change on the display. it means everything is in order, the conductor is not damaged
  • Connect the black probe into the COM nest, red. in the jack VΩma
  • Set the device switch to the sound icon position (diode)
  • Connect any of the probe to any of the cable contacts
  • Touch the second probe symmetrically located contact on the other end of the cable
  • In the presence of contact at the ends of the conductor (in the absence of a break), the beep will sound. it means everything is in order, the conductor is not damaged

Measurement of voltage by a multimeter on individual PC elements can help determine the source of a malfunction. To do this, you need to connect the black probe into the COM socket, red. in the VΩma socket, set the switch to the DCV = 20 position. For measurement it is necessary to attach a black dipstice to minus the source, red to the plus. If you confuse plus and minus, then this is not critical. just on the display the value will be displayed with the “minus” sign. Examples of using:

How to check computer motherboard for performance

So, the question arose: “How to check the motherboard?”In order to check the working capacity of the motherboard, it is necessary to have an obviously serviceable power supply and processor first. The processor fails is extremely rare, but the power supply is better to temporarily connect 100% working. 1) First of all, the motherboard check should be started with inspection and search for visible defects (cracks, Nagar). Visually check all the capacitors on the motherboard for breach. The exploded and swollen capacitors often cause the inoperability of the motherboard. If you find the swollen capacitors, then the motherboard needs to be replaced. It will not work for steadily.

2) Reset CMOS settings. Bios Settings Dzhamper is usually located near the battery on the motherboard and is marked with CLR_CMOS or CCMOS. This is a jumper, on which 3 contacts. 1 and 2 Contacts are closed as usual.

To reset to factory settings, you need to close 2 and 3 contacts for 20 seconds, and then return the jumper to its original position. 3) Disconnect the power supply from the network. Disconnect all loops from the motherboard (except for power) and devices (hard disk, drive and t.D.), remove all the boards from the slots (video card and t.D.), remove the RAM. In the motherboard, only the processor connected to the processor and speaker fan (internal speaker) must remain installed in the motherboard. Turn on the power supply to the network. Run a computer by closing the corresponding front panel connectors on the motherboard (PWR). The speaker must begin to issue a soundless memory volunteer. On different patterns of the motherboard it can be different. Usually it is a continuous squeak. If the speaker makes a signal, then not everything is lost and the motherboard is most likely good. If there is no sound, the motherboard is defective and it must be replaced. 4) Disconnect the power supply from the network. Install the serviceable memory module in the first slot. Turn on the power supply to the network and start the computer as in.2. The speaker must begin to issue a video card error audio signal (here is described here to check the motherboard without a built-in video adapter). This is usually one long signal and three short. If this happens, then the motherboard in 98% of cases is operational. If no sound, try replacing the RAM module or install it in another slot and follow.3 first. Do not forget to disconnect the power supply before pulling out or insert memory module or extension board (video card and T.D.) 5) Install the video card. If there is an additional power connector on it, do not forget to connect it. Connect the monitor and run the computer. The speaker must publish one short beep, and on the screen appears the screensaver BIOS.

If this does not happen, then the video card is most likely faulty.

If 1-4 items are successful, the motherboard is most likely good and that computer does not turn on the other device. For example, video card or hard disk.

How to check computer motherboard for performance

This is a small article on the rapid diagnosis of motherboard for performance without seizure it from the system of the system block of the computer. You will learn how to check the motherboard for the most frequent mistakes, without applying to special efforts. You can read more about the repair of the motherboard in the article “How to repair the motherboard” (show the hint / Open article fully).

The diagnosis of motherboard is advisable to produce with such symptoms as:

So, to access the motherboard, you need to remove the cover cover of the system block of the computer (show the hint / open an article completely).

Then visually inspect the motherboard for the presence of swollen capacitors and if any, then proceed to repair (show the hint / open an article completely)

Swollen capacitors on the motherboard

If there are no swollen capacitors going on. Pull out all the stakes of memory from the motherboard, moving to the slot latch side (link to the article how to disassemble the computer) and start the computer by clicking on the power button. A beep should be opened, indicating the absence of memory modules (show the hint / open an article completely).

If there is a beep, then with more probability you can talk about the working motherboard.

Note: Signal may not be in the absence of dynamics on the motherboard. To diagnose, it is necessary to connect it to it. Dynamics connection diagram to motherboard is shown below

On this simple diagnosis of motherboard for performance is over. If you have questions about how to check the motherboard, ask them on our forum or write in the Комментарии и мнения владельцев.

Diagnostics of computer motherboard

Our site already has a material about checking the health fee. It is quite common, so in today’s article we want to stay in more detail on the diagnosis of possible problems of payment.

We carry out the diagnostics of the motherboard

The need to check the board appears in suspected fault, and the main of them are listed in the relevant article, so we will not consider them, focus only on the test methodology.

All of the following procedures must be performed only after disassembling the system unit. In some methods, it will be necessary to connect the board to electricity, so we remind you of the importance of safety safety. Diagnosis of the motherboard includes a power supply survey, connectors and connectors, as well as inspection for defects and checking BIOS settings.

Stage 1: Nutrition

When diagnosing motherboards, it is important to distinguish the concepts of “inclusion” and “Run”. The motherboard is included in the case when nutrition is normally served on it. It starts the same when the built-in speaker gives a signal, and an image appears on the connected monitor. Therefore, the first thing to check is whether electricity on the motherboard goes. Determine it is quite simple.

    Disconnect all peripheral devices and cards from the system circuit, leaving only a processor, a processor cooler and a power supply that must be operational.

If the board connected to the power supply does not submit signs of life, most likely, the problem is somewhere in the power chain. The first thing you need to check. Connectors of BP. Inspect the connectors, are there any traces of damage, oxidation or contamination. Then go to condensers and a BIOS backup battery. If there is defects (bloating or oxidation) item must be replaced.

In some cases, inclusion seems to be happening, but after a couple of seconds, the power supply stops. This means that the motherboard is shortly closed on the system unit body. The reason for such a KZ is that the fastening screws are too much pressed the board to the body or between the screw, the case and the circuit there are no cardboard or rubber insulating gaskets.

In some cases, the source of the problem may be faulty POWER and RESET buttons. Details of the problem and methods to combat it are covered in the article below.

Stage 2: Run

Making sure that the fee is given normally, it should be checked if it starts.

  • Make sure that only the processor, cooler and power supply unit are connected to it.
  • Connect the board to the power supply and turn it on. At this stage, the fee will signal the absence of other necessary components (RAM and video card). Such behavior can be considered the norm in such a situation.
  • The signals of the fee of the absence of components or problems with them are called post-codes, they are supplied via speaker or special control diodes. However, some manufacturers in the “motherboards” of the budget segment are saved, removing both diodes and speakers. For such cases, there are special post-cards that we talked about the article on the main problems of motherboards.

Problems that may occur at the start stage include failures with a processor or physical problem of the southern or northern bridges of the board. Check them very simple.

  • Disconnect the board and remove the cooler from the processor.
  • Turn on the board and bring your hand to the processor. If a few minutes have passed, and the processor does not generate heat. it is either failed or connected incorrectly.
  • In the same way, check bridges. They are on the board two: the northern (the largest chip, often covered with a radiator) and the southern (smaller chip, usually without additional cooling). The approximate location of the bridges is shown in the image below. the north is indicated by the number 1, the southern. digit 2.Here the situation is exactly the opposite of the processor: strong heating of these items speaks of a malfunction. As a rule, the bridge is not subject to replacement, and you have to change the entire fee.

If there are no problems with the start of the board, proceed to the next stage of verification.

Stage 3: Connectors and Peripherals

As practice shows, the most common cause of problems is failed hardware. The method of determining the culprit problem is quite simple.

  • Connect peripheral devices to the board in this order (not forgetting to disconnect and turn on the board. the connection “on the hot” can output both components!):
  • RAM;
  • Video card;
  • Sound card;
  • External network card;
  • HDD;
  • Drives of magnetic and optical disks;
  • External peripherals (mouse, keyboard).

If you use a post card, then you first connect it to a free PCI connector.

In addition to directly connected hardware components, the problem can create problems with the corresponding connections on the motherboard. They need to be examined, and, in case of problems, or replace independently, or contact the service center.

At this stage, problems with the BIOS settings are manifested. for example, an incorrect loading medium or a system cannot determine it. In this case, the post map and manifests its utility. according to the information displayed on it, you can understand which setting causes failure. Any problems with the BIOS parameters are easiest to fix by dropping the settings.

On this diagnosis of motherboard can be considered complete.

Finally, we want to remind you of the importance of timely system maintenance of the motherboard and its components. by spending the regular cleaning of the computer from dust and examining its elements, you significantly reduce the risk of problems.

Check without processor

Without collecting a computer, you can check the system board system and integrated CMOS. To do this, it is enough to connect to the component. If the LED is burning, then the electric current is fed normally. Alas, but the LED is not on all motherboard.

Check backup power, which provides CR 2032 batteries, can be used by multimeter. The supplied voltage should be about 3 V. If it does not match the norm, the battery should be replaced. this may be the cause of glitches in the work.

With further diagnostics, it is necessary to connect all other components alternately and check the speaker reaction. Naturally, it connects first.

Checking CPU performance

This test is recommended to do to test performance. for example, after it is changed after the component is overclocking. Before such a test, make sure that the “stone” does not heat above 70 degrees. For performance test in test utilities AIDA64 or SANDRA, special benchmarks are provided.

You can make it using the same AIDA64. After starting the program in the main menu, select the “Service” tab and find the “System Stability Test”. In the window that appears, install the Stress CPU tick. If you want to check how the CPU will show in a bundle with other components, put the check mark opposite their names.

Next, click the Start button. Depending on the performance of the device for checking, it will be necessary for 15-30 minutes. In the process, follow the graphs, especially for temperature indicators. If it rises above 70 degrees, I recommend stopping the test.

When you decide that you checked the CPU and it works fine, press the STOP button. Match each other with heating and load graphics. The rule is as follows: A small load is not higher than 50 degrees, average. no more than 60, high. no more than 70 degrees.

It will also be useful for you to read “What is a TBW resource and how it is calculated” and “Paddling file for SSD is needed or disconnected?”. What Throttling CPU is and how this technology works, read here. I will be grateful to everyone who shares this post in any social network. Till tomorrow!
