It’s awful when you press the power button on your computer and it doesn’t turn on at all, maybe it powers up but shuts right down. There are many reasons why your computer isn’t turning on and the problem range from simple and easy to fix, to much more complicated. Modern computers are complex machines, so it might not be clear where the problem has originated but troubleshooting can help you figure out what the problem is. Here are some troubleshooting steps you should know.

Check Your Power Supply

When you start your computer and nothing lights up, and the fans don’t start, then there are generally two possibilities. Either the computer’s power supply has failed or there’s no electricity entering your computer.

If your PC is a laptop, a faulty battery could be responsible for the lack of power. So, you need to first charge the battery and check again. If that does not work, either the battery is faulty or try a different charger.

If your PC is a desktop computer, try checking your PC’s power cable by swapping for another one and by plugging it into different sockets. If these don’t work, it may be that your power supply is faulty. You can also try replacing your PC’s CMOS battery. This battery stores your BIOS setting on your motherboard.

Check Your Monitor

If it sounds like your PC has power because its power light comes on but you don’t see anything on the screen, there are a couple of possible faults.

If you have a laptop PC, it can be that your laptop is in sleep mode. To check that, press the power button for 5 short seconds and then press it again to shut it down completely and restart from the cold.

If you have desktop PC, it could be that your external monitor could be faulty. To check this, try connecting and reconnecting the power cable connection to the monitor to make sure that it’s properly connected to your computer. If this doesn’t help, try plugging your computer into another monitor or even a TV and see if it works. That way you’ll be able to determine whether your monitor is dead and you need to buy a new one.

Unplug Unnecessary External Hardware

If your desktop PC still doesn’t start, unplug external hardware attached to your computer—controller, external hard drives, and USD headsets. In some cases, it may not even be the device at fault, but the port on your computer.

Before starting your computer, disconnect everything—except keyboard, mouse, and display. Try rebooting your desktop PC again. If it successfully reboots, shut it down and repeat with another peripheral. Keep repeating the process until it fails to start, then you know you have detected the problem.

Reseat the Internal Components

Sometimes, the internal hardware of your desktop PC can come loose inside due to being transported. The internal components of your desktop include your RAM, graphics card, and motherboard cables. Remove these hardware’s completely, then clean them and plug them back in, ensuring they are placed in all their respective sockets. You can always ask your friends or seek professional help for help in this matter.
