Tech support concept. But the motherboard might still be functional. The first to thing to do is perform a brief visual inspection on the system itself. Are all components seated properly? If the system turns on, are all the fans spinning? If the motherboard has a visual LED indicator, what color is it usually green means everything is OK? If there is any doubt, try re-seating components as necessary and try starting the system again.
Some modern motherboards will even have LEDs for individual components. The second thing to do is confirm whether the motherboard produces error or beep codes when trying to start the system up with key components missing e. This assumes, of course, that the system still turns on. For example, if you remove the RAM and start the computer, does it respond with error beeps?
Do note that some modern motherboards no longer support beep codes please consult the manual of your motherboard to make sure yours does. For more details on different motherboard beep error codes and what they mean, please consult these resources here. Power supplies can appear to still be functioning, as the power supply fan may still run, as well as the CPU fan and any lights that you might have on your computer.
The silver CMOS battery inside a motherboard. In a shipment of motherboards, it's unusual to find even 1 DOA. In a shipment of cheap motherboards, it's not uncommon to find half or more DOA, and many of the remainder failing soon after they're installed.
In a working system, it's very uncommon for a high-quality motherboard to fail other than from lightning damage see Computer Power Supplies and Protection or other severe abuse. In particular, it's nearly unheard of for a motherboard to fail while it is running, as opposed to when you start the system. A dead system is more often caused by a dead power supply than a dead motherboard, so the first step to troubleshoot an apparently dead motherboard is to swap in a known-good power supply.
If the system remains completely dead with a known-good power supply, it's likely that the motherboard is defective and must be replaced.
It's not uncommon for a motherboard to fail partially. For example, an ATA interface or the embedded video, audio, or LAN may stop working, while the rest of the motherboard functions appear to work normally. It's possible to work around such partial failures; for example, by disabling the failed function in BIOS Setup and installing an expansion card to replace the failed embedded function.
We recommend against this practice, however, because a partial motherboard failure is often soon followed by a complete failure. If the processor is the brain of your computer, the motherboard is the heart—it's the place where the different parts of a computer connect and talk to each other.
So if your motherboard has a problem, it's a bigger issue than just replacing one part. Usually, motherboards are sturdy enough to take the ravages of daily use. But there are some things you can do to make sure it keeps running right. Protecting the motherboard from damage is paramount to protecting every other component. Avoid some of these common mistakes that damage a motherboard, and you'll save yourself from headaches.
This problem is more prevalent in desktop computers but also yet rarely occurs in laptops. Whether you like to build your own PC or buy one assembled from somewhere, there are chances of a short circuit if it hasn't been assembled properly. The motherboard conducts electricity and passes it to other components, so it can't come into contact with any metal, like the case itself or a badly fitted component.
Loose CPU coolers often cause irreparable damage to motherboards. Also, check for loose cables, a common PC maintenance mistake. In the course of assembling your PC, you need to fit the motherboard properly in the case. The motherboard has a few screws that you use to attach it to the case.
Make sure you use every screw and that it is tight. A single loose screw can fry a whole motherboard—it does happen! In short, the inside of your computer should be neat and organized. If the motherboard ends up getting into contact with an unintended object, it can cause a short circuit. The motherboard is where your computer's power supply unit PSU is connected. This sudden change of voltage can cause damage to the delicate circuits in a motherboard.
Connecting your computer to a power outlet that has frequent fluctuations in electrical output may also cause damage to your motherboard. Though at times immediate damage may not be visible, it may harm the motherboard over time.
To protect your motherboard from electrical spikes, use a high-quality surge protector that can neutralize the effects. Surge Suppressors should be replaced every five to ten years depending on the brand and model you install. It is also important that you register the warranty to cover your electronics in the event of damage. In the event that damage does occur you can fail back on the registration of your surge suppressor and make a warranty claim.
Dust, Pet Hair and Debris. Dust, pet hair and foreign debris can be a sure motherboard killer. When these things collect in your machine, they start blocking the air circulation that keeps the machine cool. It is like harmful fat that blocks your arteries that cause a heart attack. Most computers cool themselves down by intaking cool air from around the computer and exhausting the hot air out.
If fans are unable to move air the inside of your device is going to cook your components like hot dogs on the grill during 4th of July. If you have a Desktop PC it is advised to have it installed on top of your desk rather than on the floor. If your desk has a cabinet built in for the computer to be installed make sure it is well ventilated.
