Motherboards come in different sizes. It is important to note that some motherboards may not be fit for your computer case, the system unit. To solve this, make sure to look at the motherboard specifications, specifically, the form factor.
Form Factor: Refers to the size, shape, and physical specifications of a hardware component.
4 Primary Motherboard Form Factors
Sample image of BIOS
Beep codes given by the motherboard
BIOS: The firmware responsible for your system boot up
UEFI: Alternative for BIOS, uses only info needed to launch the OS boot process
CPU: Commonly known as the brain as the computer, responsible for process input, storing data, and output results
When building a new computer, some people may find that their computer is unable to turn on. Before jumping ships and buying new computer parts or perhaps a new computer, you may want to try updating your BIOS.
If you have attempted to turn on your computer and are met with a black screen, this may be a sign given by the motherboard that it is having trouble communicating with your CPU. This happens when you have a new CPU paired with an older motherboard. Fortunately, most motherboards come with a feature called BIOS Flashback which allows you to update the BIOS without needing a CPU, GPU, or memory installed.
Computer POST and beep codes
The computer POST (power-on self test) checks the compatibility of the hardware components before fully booting up. One or two beeps are given when a computer passes the POST and will continue to boot. If a computer fails the POST, the computers may give a beep code.
Common causes of POST failures
BIOS ROM
CPU
Motherboard
RAM
Video card
PC Boot Process: Power to CPU → Loads UEFI/BIOS → Runs POST → Identifies System Devices → etc…
Motherboard issues
Black screen: a black screen before login or continuous system reboots indicates a fatal system error. This was also known as a blue screen of death in previous Windows versions
Distended capacitors: Capacitors on the motherboard may swell or leak fluid when they become overstressed. If they fail, the motherboard will fail.
Overheating: Computer’s internal components generate heat that does not dissipate, the computer’s functions and hardware may be damaged
Sample Error Codes:
201: Memory error
301: Keyboard error
Power Issue Behaviors: Unexpected shutdown, continuous reboot, unable to power
Boot Error Indicators: audible beeps, numeric codes, error messages
Causes of Overheating: inadequate airflow/circulation, poorly installed fans, failing fans, dust buildup, environmental issues
You can use temperature monitoring tools on your computer to troubleshoot this
Smoke or Burning Smell: short circuit, improperly seated connector
Sample image of memory error
Memory Troubleshooting
Memory damage can be caused by: power spikes, improper handling, and electrostatic discharge
Symptoms: system lockup, blank screen on boot, failure to boot, blue screen errors
Error Causes: software or hardware related errors
Add image of blue screen memory error
Can resolve the issue by removing a memory module one at a time until it works
Tools that can be used when removing a module are static wristbands, antistatic bags, and a static mat
Processor Troubleshooting
To prevent electrostatic discharge, work on a static mat or ground yourself with a wrist strap
Overclocking may cause instability, excess heat, and hardware failures
Installation issues may be an issue
Symptoms: smoking, no display
Overheating prevention: Use a CPU cooler, monitor the temperature, ensure all fans are working properly, have proper air circulation
