Power Supply Issues

One frequent culprit why your computer won’t turn on is power supply issues. Ensure that the power cord is securely plugged into the computer and the power outlet.

Verify that the power outlet is functioning by trying another device. If necessary, test the power supply using a power supply tester or by replacing it with a known working one.

Loose Connections

Loose connections can also prevent the computer from powering on. Open the computer case and check for any loose cables connected to the motherboard, hard drive, or other components. Disconnect and reconnect these cables firmly to establish a proper connection.

These cables are delicate, so be careful. Calling a Computer repair service can help test for loose connections while also making sure your cables are safe.


Overheating can be another factor. Check if the computer’s fans are running and clear them of any dust or obstructions. Use compressed air to clean the fans and heat sinks. Additionally, consider reapplying thermal paste on the CPU if it has dried out.

Hardware Failure

Hardware failure may also cause the computer to not turn on. Remove any recently added hardware components and attempt to power on the computer. To identify a faulty component, try testing each hardware component by removing them one at a time and checking if the computer powers on. If a faulty component is identified, consider replacing it.

Software Issues

Software issues can cause a dead computer. Perform a hard reset by holding down the power button for 10-15 seconds to discharge any residual power and then try turning on the computer again.

If you recently installed new software or updates, attempt to start the computer in Safe Mode to diagnose any conflicts. Utilize system restore options or bootable media to revert to a previously stable state of the operating system if necessary.

Faulty Motherboard

Another reason for a broken computer could also be a faulty motherboard. To test the motherboard, remove all unnecessary components and cables, leaving only the essentials such as the CPU, RAM, and power supply connected. If the motherboard is suspected to be faulty and still under warranty, reach out to the manufacturer for further assistance.
