Why computer won’t turn on? The reasons

For you to enjoy your computer again, you will first have to understand what is wrong. To do this, here are some reasons your PC may not work:

Lack of connection: One of the main reasons the PC does not boot is because some cables that make up your system are not well connected, either internally or to the current. There are many times. Some wires or plugs of your home do not work correctly and prevent the connection from reaching your computer.

Screen problems: There can be two main problems related to the screen. The first is that the brightness levels are so low that you cannot see the screen well. The second problem is that the screen is not correctly connected to the rest of the equipment.

Voltage problems: Sometimes the problem may be a power failure, something that will be clear when you try to turn on the PC.

Why computer won’t turn on? The solutions

Sometimes, although it may not seem so, these problems can be solved with simple procedures. So you can fix your PC quickly, here are some tips you should keep in mind before calling a specialist.

The first step is to verify that everything is well connected. This is the first thing you should do if your PC does not respond since it is possible that some power does not reach the power or that it is not properly fitted in the slot of your PC. Another trick that should never be missing in this process is to disconnect everything, wait a while and restart the computer. In the event that an electrical problem has occurred, letting the PC rest for a few seconds may be the definitive solution.

If you have already gone through these steps and still your PC does not boot, take a look at the following possible solutions:

  1. Remove any USB and memory card
  2. Start the PC in safe mode
  3. Remove recently installed programs
  4. Examine the Hardware and identify problems

Remove any USB or memory card from your PC

Once you have verified that the connection to the power does not generate problems, make sure that there are no memory cards or USB connected. Check, also, that there are no DVD drives in the respective compartment, as that could also prevent the computer from starting correctly.

When the problem is because of these reasons, the phrase “Operating System not found” usually appears on the screen. That means that the BIOS, the primary input and output system, is not preparing for a normal startup but is trying to configure itself for the startup from one unit that is connected to the PC, which causes it not to work.

Start your PC in safe mode

If you have tried to start your computer traditionally and it does not start, you may have to start it in safe mode, by pressing the F8 key while the PC tries to boot. The option to turn on in safe mode will be displayed.

Press the accept option to be able to undo the changes that have had to do with the equipment failure.

Remove recently installed programs

One reason your PC may not work or not start properly is because of the latest installed programs. Not only is it possible that the programs have filled your computer’s memory too much, but maybe some of those programs are damaging your computer. In these cases, having a good antivirus is essential, as it will prepare your PC to combat attacks of damaged programs.

To solve the fault, we recommend that once you have entered safe mode, eliminate the heaviest programs that you do not use or those that may be damaged.

Examine the Hardware well

In case you have changed the hardware of the equipment recently, investigate if this may be the problem in question. To begin, make sure that the hardware is compatible with your computer and that it does not bring with it certain defects that prevent the correct startup of the PC.

In most cases, these types of problems are solved because it is enough to check through the BIOS if the computer processor is well connected with the hardware input and output devices (screen, keyboard, hard disk, etc.) In case the connection is incorrect, it is surely necessary to change the hardware.

If this process is very complicated, we recommend that you do not touch the system much and that you wait for an expert. Otherwise, you could damage the PC more.
