Common errors that usually occur

The most common reason for a PC not booting up or starting it that a hardware accessory or the hard drive itself does not work. It is the common cause and several users might not be aware of that. The hard drive is the area where all the files are stored and are contained. There is no need to panic because all the files are safe, but not accessible at the moment.

You will want to disconnect the power and storage devices from your computer system. Usually you will not think of doing it because you will be so frustrated with yourself that you might keep pressing the power button with immense force several times. Well, that is not going to help your cause.

Once you have finished disconnecting the power, it ensures that you are performing the procedure safely, with no power discharge. The first step would be to clear the CMOS. You will want to then clear the BIOS memory which is present on your motherboard. What happens here is that, it resets the BIOS settings.

The settings become factory default levels. That is very essential for ensuring that the computer system does not lock up. Fixing it, with misconfigured BIOS is not a wise thing to do. In some cases, clearing the BIOS memory enables the PC to start working. In that case, you can go ahead and start using your system.

Reseat the cable plugs and internal components

You will then have to test the power supply. Sometimes the power supply can cause startup issues, which takes many people by surprise. When there is a problem with the power supply, then you will want to replace it. Sometimes the power supply does not work like it is supposed to or does not provide enough power, this is why replacing it is a good idea.

You will then want to reseat everything back. This helps in reestablishing the card, cable, and other connections inside your computer. The CPU and motherboard of any PC should be firmly attached. In some cases, loose connections do cause minor issues which can then affect the performance of the PC.

You will need to reseat the memory modules, reset all internal data and power cables, and reseat any expansion cards. You should also reattach your keyboard and mouse. In many cases the mouse and keyboard never causes the PC to hang. You might also want to check the video card and CPU, memory used is compatible with your motherboard.

Check for electrical short circuits

Start your PC with essential hardware only. The purpose here is to remove as much hardware as possible while still maintaining your computer’s ability to power on. As you reattach all the hardware components on your PC, you will eventually find out the part that is causing the problem.

As you reattach all the parts one by one and if the PC is causing problems, then you can easily identify that part and then get them replaced immediately. You can also consider stocking spare computer parts. They are not expensive and can be stored in safely, just in case.

Some patience is required to fix a PC not booting up. When you are not able to get it right the first few times don’t give in or become annoyed with yourself.
