The motherboard in a computer serves as the connection point for the other component parts of the machine. This opens the way for more complex circuits to be implemented without the need for complicated wiring diagrams. With the aid of a basic multi-meter it is not just able to detect general electronic problems, but also troubleshoot and test PC motherboards.
How can I Test DC Voltages?
Step 1
Verify that you have the 20 pin ATX connector is connected and the computer is powered up. Set the multimeter to 20 Volts directly current. Check the back side of the connector using the probe of the black multimeter and contact pins17,15 or 16 by using search in black search (GND pins).
Step 2
Check the following pins using the probe in red (searching for the explanations in the parentheses) For example, Pin 14 (green, PS On) should be between 3 and 5 volts as well as pin 9 (purple, VSSB) should be at 5 voltages (anything less than that indicates a power supply problem). When you turn off your computer and turn it off, your PS On value should be at 0. Other readings indicate the switch being damaged.
Step 3.
Make sure you check The pin 8 (grey, Power OK) by using the red probe. Make sure it's more than 2.5 V. This means that the computer will be able to begin. When you press reset you should see the Power OK reading should decrease to zero and then rise another time.
Motherboard and PSU Tests for Open/Short Circuits
Step 1.
After a couple of minutes then turn off the computer and allow the remaining charge to drain. Set the multimeter at its lowest level of Ohm (about 200) and then turn it off by rubbing the leads of the probe to each other. Zero readings should appear identical as when connecting the probes' probes to the pure metal of the chassis of your computer.
Step 2
The removal of the ATX connector from the memory board must be done with care. Verify the A/C ground pin using the red PSU lead as well as the white wires that are on the connector. The pins should read zero.
Step 3.
Examine the wires with coloured pins value in the connector D/C employing the red probe while making sure to keep your black lead in the frame. In the case of all wires with coloured wiring is concerned, these wires must also be reading at least 50. Make sure to keep the white lead in the frame, and make use of the probe in red to verify for the value of wires with coloured pins in the connector D/C. The wires that are coloured should have the reading 50 or higher.
Step 4
Get rid of the motherboard connector to the CPU. Use this ATX 20-pin chart to connect to PINs connected to the board's connector. Make sure to keep the black lead to the skeleton, and make use of the red data for testing the GND pins of the motherboard connector on pins 17, 3 5, 7, 13 15 and 16. The pins should return to zero when you read. A different perusing indicates the possibility of a defective connector.
The motherboard is an often forgotten component when developing a pc gaming computer and also does not obtain the exact same attention as the graphics card or CPU.
It's just as essential, though, since it links whatever with each other and also controls the efficiency.Pc gaming motherboards are a little various from regular motherboards.
They include extra functions like overclocking capacities, additional USB ports, headers for additional fans and lights, and also ports and also slots for graphics cards.
A pc gaming motherboard develops a steady environment for all the other components to beam and is crucial to any gaming rig.There are lots of video gaming motherboards on the marketplace, and also it can be hard to make a decision which is ideal for you.
They have considerable cost variances, and also they can additionally support various processor brands as well as fit in various case sizes.
We've made a listing of budget PC pc gaming motherboards that support Intel and AMD CPU chipsets.
