Why isn’t my computer turning on? Here’s How to Repair It

There’s no need to fear if you’ve just discovered a dead PC. It may happen for a variety of causes, including power outages, device malfunctions, or software faults. As a result, it is typical to be unsure of where to begin or what the issue is.

Although it may seem that there is nothing you can do to repair your computer, there are some options to consider before spending a lot of money replacing it. The following are some probable reasons and solutions.

1. Try Different Cables

While this is exceedingly rare, it is wise to investigate and rule it out first. Examine your power cord; it may have gone loose or been detached, in which case you must reconnect it. Occasionally, the issue is the cord itself.

It could be a good idea to replace out the power cable if you have one. You may reboot your computer using the new power cord.

2. Decode the Beeps

When you attempt to turn on the computer, you may hear a sequence of beeps coming from the motherboard. While a single beep shows that everything is well, a lengthy and continuous series may indicate that the power supply has a serious defect.

There is no standard set of error codes for troubleshooting. Your computer may produce error codes in the form of a succession of short and lengthy beeps that sound similar to Morse code. To discover out what these noises represent, see the computer’s user handbook.

You can get this information on the manufacturer’s website if you don’t have the computer’s handbook. If your computer doesn’t beep at all, consider placing a digital monitor or an inexpensive speaker on the motherboard’s header to check for faults.

3. Try a Different Power Source

If your computer does not boot up at all—no lights flashing, no error messages blaring, and no fans spinning—it most likely has a power problem.

You might try disconnecting the power source and plugging it into a known-working wall socket. If you’re using a laptop, make sure the charger is connected in and the power switch is turned on.

4. Check if Your Power Button Is the Problem

If your computer does not start but the motherboard light or fans are on, you may have a problem with your power button. To troubleshoot, turn on the motherboard onboard button.

However, since motherboards differ, not all of them feature an inbuilt power button. If you can’t find it, you can browse through the motherboard handbook.

If your motherboard lacks an internal power button, you may kickstart your computer by touching a screwdriver to the power switch header pins. This is a good temporary fix to test whether the issue is with your power button or the casing. If your computer is making noises but you’re not seeing anything on the screen, it might be the display. To begin, ensure that your display is connected to both the computer and the power source.

5. Check Your Display

You should also double-check that the monitor’s power cable isn’t broken. If another power cord does not cure the problem and you have a spare monitor or TV to connect, try plugging it in. If your computer now boots up, it seems that your display has to be replaced.

When troubleshooting a problem, it is preferable to remove all factors that might be causing the problem. Concentrate on the most probable source. If you’ve gotten this far and the issue still continues, unplug everything and reboot the computer using just the keyboard and mouse.

6. Unplug USB Devices You Don’t Need

In a pinch, troubleshoot without even a keyboard and mouse to confirm that none of the USB devices are creating a conflict. Ports are sometimes the source of problems. As a result, ensuring that the ports remain empty throughout the startup process might be beneficial.

Overheating might cause a computer to shut down. If there is a lot of dust on the vents or fans, it might cause overheating and cause your system to shut down.

7. Reduce the Heat

Waiting for your computer to cool down is the greatest troubleshooting option in this circumstance. Third-party applications may also be used to control and monitor your fan speeds and cooling system. Alternatively, you may utilize an external hardware cooler. Above the CPU, your PC should have vacant compartments for external cooling.

Check the reset switch if you’ve connected your computer to an uninterruptible power supply (UPS) or surge protector.

8. Check the Surge Protector

Most surge protectors include a built-in reset button that must be pressed after a power surge or blackout.

This does not normally result in boot failure, although it may happen on rare circumstances. If you’ve tried everything else, it’s always worth altering it to see if it makes a difference.
