computer will not boot up

Your computer will not boot up happens when you press the power button of your computer but it brings no light. We will look at this problem in two ways, the first way is Hardware and the second way is Software. The problem must be from either of the two, there is no other one.


Hardware is the physical component that a computer system requires to function. It is the collection of all parts that can be physically touched in a computer such as the Central Processing Unit (CPU), Mouse, Monitor, Keyboard, these are the hardware, especially for the layman, but for those with basic computer knowledge or advanced, other hardware components are; motherboard, Random access memory (RAM), Graphics card, Cmos battery, Power Jack and others.

The hardware problems of a computer that doesn’t boot up can be resolved in the following ways:



Have you tried to make use of your computer and when you ON it the way you normally do, it does not boot up? It is annoying but you don’t need to panic. Here are the quick handy solutions to the problem.

How do you know that it is a power issue? It is when you press the power button but nothing is showing up on the screen, no sound, the fan is not rolling, computer temperature does not change. Obviously, the problem comes from the power.

Now that we know where the problem comes from then the issue should be traced to the components powering the computer, like the power cable or power Jack.

Power cord

A power cord is a primary cord that provides power to the computer. The first thing you should do if your computer does not boot up is to check its powering cable. Use another cable to power your computer or use your computer suspected cable in another computer. If another cable is on your computer then you need to get another cable but if your computer cable does not work on another computer and/or another cable does not work on your computer then try the next troubleshooting.

Power jack

Power jack

A power jack is a metal box in a computer that is attached to the motherboard and which provides power to your computer. It is a port where a power cable is plugged into a desktop computer or where a charger or adapter is plugged into a laptop.

What are the signs your computer power jack is not good?

  • When Computer power glimmers on and off

  • When your laptop is working only when your battery is charged not when you plugged in a charger

  • Need to plug in a charging cable in the socket before your computer works

  • The laptop battery does not charge when the charger is plugged

  • Desktop does not power when plugged

  • Produce sparks when inserting the cord into the Desktop power jack or adapter into the laptop power jack.

  • Desktop or Laptop shuts down suddenly while in use

How to fix the Computer power jack problem

If the power jack is removable that has a pin, detach it from the motherboard and reattached it, but if the pin has slacked and could not attach firmly to the motherboard, you can attach it with gum.

If the first step does not work, replace the entire power jack

If the power jack is not removable, solder the power jack if it has been removed from the motherboard

If it does not work then change the entire power jack

Light with beeps (sound)

The number of beeps a computer made indicates different problems it has. Some Computers make one been, two beeps, three beeps, and so on

Three beeps

Three beeps that repeat after a pause that happens when you switch on your computer indicate a problem with the Computer memory(RAM).

How can you solve memory errors?


The first action to take is to reduce the number of RAMs on the computer, that is if you just increased the number of RAM. Once the number of RAM is reduced, then restart the computer and wait for some minutes to see if the computer will boot up or not. If it does, return the RAM you just removed to see if you can increase the number or should leave it like that.

If you reduced the number of storage (RAM) or it is only one RAM on your Computer then you need to replace it with another one. If you do that, restart your computer and wait for some minutes, your Computer should boot up.

Note: There are another three beeps that play and then stop as the computer starts successfully, this type of beeps means that the BIOS was restored. It is different from the beeps mentioned above.

Processor error


There are different ways you can detect if the problem is from the Computer processor, One of the signs is Five beeps that repeat after a pause that happens when you switch on your computer, this indicates a problem with the Computer Processor.

This can be resolved by reseating the CPU, dusting up your CPU, or it can be solved by removing the Processor if it is removable (like those in Desktops), reinserting it, then restarting your computer

CMOS error


CMOS (Complementary metal-oxide-semiconductor) is the battery that powered the memory chip in a computer system, it stores startup information. This battery is not commonly preventing a Computer from booting up but we need to check it since it stores essential system information like basic hardware settings.

One of the ways to detect CMOS battery error is ten short beeps, ten beeps repeat after a pause that happens when you switch on your computer indicates a problem with the Computer’s CMOS battery. mean that there has been a CMOS problem. This beep code is usually caused by a hardware failure.

How to solve CMOS battery error?

Find the battery on the motherboard of your computer it is silver-colored coined-shape, remove it from the motherboard, clean it and reseat it then restart your computer and wait for some minutes.

If your computer does not boot up, remove the battery and replace it with the new one, the battery does not cost.



The motherboard is a printed circuit board and foundation of a computer that is the biggest board in a computer chassis.

A motherboard is one of the most essential parts of a computer system. It holds together many of the crucial components of a computer

The motherboard serves as a single platform to connect all of the parts of a computer. It connects the CPU, memory, hard drives, optical drives

Check your Hard drive

A computer hard drive is a device that stores the operating system, programs, and data files on a Computer. Hard drive sometimes causes why your computer not boot up. There are many signs it gives to know that the issue is from your Computer Hard-drive, But the most common sign is when your Computer flickers ON and OFF.

How to solve the Computer Hard-drive problem?

Remove the Hard-drive of your computer and reseat it, restart your computer and wait for some minutes for it to boot up. If your computer did not boot up, change the Hard-drive connector. But if the options do not work then you need to change your Hard-drive.

Before you assume that your Hard-drive has crashed, do Hard-drive testing on your computer.

The last option to solve your computer will not boot up through Hardware is to Remove and reseat all the components in your CPU or Laptop.

Remove all the components (i.e RAMs, CMOS battery, Processor if it is removable, Cards, and other removable components in your Desktop CPU or Laptop.

Dust the CPU casing, motherboard, and the components you removed (dust the components gently as to avoid damage)

Reseat all the components, restart your computer and wait for some minutes.


Software is a collection of instructions that tell a computer how to work. This is in contrast to hardware, from which the system is built and performs the work.

There are many ways to solve computer does not boot up problems through software. It might be the software that was not installed properly, when a particular driver corrupts, Operating systems, drivers, or programs update that failed when the system did not shut down properly, corrupt the Operating system, BIOS settings, and some others.

Operating systems, drivers, or programs update that failed

It happens sometimes when you are updating some programs, drivers, or even an Operating system, due to abrupt power or network failure, the update stops. When it happens like that it prevents windows from booting up.

There are different ways to solve the problem, but the simplest one is to back up your files and change your Operating system. If you repair the OS or may not take long before it gets corrupt again.If you tried all the suggested solutions but none of the works for your computer that does not boot, then you are advised to go and get a new computer.
