What Do I Do If My Computer Does Not Turn On?

Have you checked your power supply for issues?

Is the power cord connected properly at the back of the computer?

Have you checked the power buttons at the back of your computer?

Have you recently added any third-party hardware?

Have you tried unplugging the cables that may have stayed connected on your PC?

Does your PC create a series of beeping sounds when you try to turn it on?

Have you checked your PC’s motherboard?

Have you checked your PC memory?

Have you checked the PC hardware components for issues?

Try plugging it to a different socket as it could be that the power supply has run out or failed. It could be that the power supply is insufficient for the hardware’s needs.

If it is connected correctly, try to disconnect and reconnect both ends to ensure that the cable is not loose.

Try checking the power buttons at the back of your PC to make sure there are no additional buttons that are turned off.

If a third-party hardware is added, try to temporarily disconnect it and check that it is not causing the issue.

Try to check if there are superfluous external hard drives that are connected. Sometimes the problem is not the device but the port on your computer.

Check your PC manual to find out what the beeping problem means. You can check it on a manufacturer’s website if you don’t have it. Ask help from an expert if you don’t know how to fix it yourself.

Try to open the computer case and do a visual check on the motherboard. Look for any bulged capacitor, a crack in the circuit board, broken pins, or melted integrated circuit. Replace the damaged part of the motherboard if necessary.

Memory problems contribute to all causes of PC problems. Ensure that the memory installed in the PC is the right type for your system, properly installed, and fully seated.

Try replacing those faulty components in this order: processor and heatsink, video card, sound card, disc drive, and hard drive.

Examine the parts on your computer case. If you aren’t confident about opening it and replacing specific components that may contribute to the technical problem, try asking for a friend or, better yet, bring your PC to a repair shop.
