How to Fix a Desktop PC That Won’t Boot

When disaster strikes and your desktop PC won't boot, it can be a stressful moment. Your precious files, contacts, applications, everything at the mercy of a machine that refuses to cooperate. Fortunately, it doesn't have to be a doomsday scenario.

Before panicking, remember that computer issues occur for a variety of reasons, and many can be simple to solve. This article provides a step-by-step guide on how to fix a desktop PC that won't boot.

Verify Your Power Source

First, you should verify that your desktop PC has a sufficient power supply. Ensure that the power cable is properly connected to the computer and the power outlet. Test the power outlet using another device, like a mobile phone charger, to ensure it's working correctly.

Check the Monitor

Sometimes, the problem isn't with the computer, but with the monitor. Ensure your monitor is properly connected to your PC and powered. Remember to check if the correct input source is selected on your monitor.

Disconnect Non-Essential Hardware

Often, a connected device can cause your computer to hang during the booting process. Disconnect all non-essential hardware like external hard disks, printers, game controllers, and other USB devices, then try booting again. If your computer starts fine, you can now reconnect the hardware one device at a time to determine the problematic device.

Try Booting in Safe Mode

Booting in safe mode is an effective way to troubleshoot your system. Safe mode starts the system with only basic files and drivers necessary to run Windows, which can help you determine if a specific software, driver, or setting is causing the problem.

Hard Drive Check

If the problem persists, there might be an issue with your hard drive. It's advisable to check the hard drive for errors. To do this, you must boot your PC from a bootable disc or USB drive, then use Windows tools such as CHKDSK to analyze and repair any found errors.

Bios Settings Check

A misconfigured bios setting can interfere with the booting process. You can enter BIOS (Basic Input/Output System) and confirm that your hard drive is set to boot first. Ensure you haven't modified any other settings mistakenly.

Reinstall the Operating System

If none of the previous steps work, there might be an issue with the operating system. You may need to consider reinstalling the operating system. Remember, this step will delete everything on your system drive, so try to back up your files if possible.

Seek Professional Help

Sometimes, the problem could be more serious, like a faulty power supply, motherboard, or processor. In such cases, it might be best to seek professional help. Always remember to back up your data regularly to prevent losing your essential files.

This guide provides straightforward steps to try when your desktop PC won't boot, intending to turn a potentially distressing situation into a manageable one. Here's hoping your PC boots up again perfectly!
