PC Not Booting? Here's Why and How to Fix It

Imagine that you're all excited to start the day. But Your PC doesn't start when you press the power button. Why is the PC not starting? Even if you have turned on your computer, it isn't booting up for some reason. It's so annoying! Your PC may not boot despite being turned on for several reasons. This article will clarify why your computer may not start and how to fix it so you can resume your day.

Why is my PC on but not booting?

Your PC suddenly won't boot up properly, and you have no idea why. Don't panic! There are a few common reasons why your PC might be on but not actually booting.

1. Hardware issue

The most likely culprit is a hardware problem with your PC. Maybe your hard drive, memory modules, or power supply have gone bad. These components are essential for your PC to start up properly. Try reseating the connections to your hard drive, memory sticks, and power supply to ensure everything is plugged in firmly. If that doesn't work, you may need to have the hardware tested or replaced.

2. The boot order is incorrect.

Maybe your PC is booting from the wrong device. Check your BIOS to make sure your primary hard disk boots first. If your PC boots from the network or an unplugged USB stick, it won't find the operating system.

3. The operating system is corrupted.

There could be a software issue preventing your operating system from loading. Run diagnostics on your hard drive to check for and fix errors. You may need to reinstall or reset your OS to factory settings to repair the software. Make sure you back up your important files first before resetting!

4. Overheating

If your PC was running really hot before shutting down, overheating components could be preventing it from booting. Give your PC time to cool, then try booting again. Check all fans are working properly and clear any dust buildup. You may need additional cooling solutions like new thermal paste or more powerful fans.

How do I fix the pc not booting error?

So your PC is powered on but not actually booting up into Windows or your operating system. Frustrating, right? Don't worry; there are some tips to get your computer back up and run it.

1. Check your hardware connections.

Check the plugs first. Make sure your display, keyboard, and mouse are correctly connected. If they are wireless devices, check that their batteries aren't dead. Also, check that all internal cables, like SATA cables, are securely connected inside your computer. Sometimes, shipping or moving your PC can knock a cable loose.

2. Try a hard reset.

If everything looks ok with the connections, try performing a hard reset. A hard reset, or cold booting, cuts all power to your PC components so they can restart from scratch. Hard reset by holding the power button for 10-15 seconds till your PC goes off. Now, Restart your PC by pressing the power button again. Resetting your PC should restore normal booting.

3. Check for hardware issues.

If a hard reset doesn't work, you may have a hardware issue preventing your PC from booting. The most common causes are problems with your memory (RAM) sticks or storage drives (HDD or SSD). You may need to test or replace these components to get your PC operational again. It's best to contact a tech support professional to understand the problem and repair or replace any faulty hardware.

4. Repair or refresh Windows

As a last resort, you may need to repair or reinstall Windows to fix a software issue preventing the boot. You can run startup repair from a Windows installation disc or USB drive to repair Windows boot files. Or you may need to refresh or reset Windows, which will reinstall the operating system while preserving your files and settings. These options will require access to a Windows installation drive.

Final Words

It is necessary for you to be able to figure out the cause of your computer's failure to start and perform some troubleshooting on it. If nothing else works, Contact a skilled computer professional to make sure it works right.
