When you sit down in front of your computer and it won't turn on, it can be frustrating, and you'll want to get it working again as soon as possible. If you're wondering why your computer won't turn on, the following troubleshooting tips should help you figure out what's keeping your computer from booting up.

Why won't my computer turn on?

There can be many reasons why a computer won't turn on. However, in an ideal world, there are two specific reasons why your computer might not boot up as it should.

There could be an issue with the internal power supply of your computer. You might need to repair the power supply and ensure it's providing stable input to the device. Another possibility is that there could be an issue affecting the system's ability to boot up. Lastly, the problem could be due to various reasons within the operating system or its files.

How to Fix a Computer That Won't Turn On (7 Reliable Methods)

When trying to fix a computer that won't turn on, you may need to try several different solutions before finding the one that works for you. Let's explore methods to resolve this issue.

7 Remedies:

Solution 1 - Check the Power Cable Solution 2 - Disconnect External Devices Solution 3 - Examine BIOS Settings Solution 4 - Boot in Safe Mode and Assess the Issue Solution 5 - Inspect Monitor and Hardware Connections Solution 6 - Boot from a USB and Run Antivirus Software Solution 7 - Check the Hard Drive and Salvage Data on Another Computer

Solution 1: Check the power cable

First, you should inspect the power cable for any issues. In most cases, the power cable might be damaged due to wear and tear. However, it could also be compromised due to voltage fluctuations in the power supply.

Check the power cable

If you have extra power cables lying around, try one of those to see if it solves the problem. You can also borrow a power cable from a colleague or friend. If this works, you'll know that you need to replace your power cable.

Solution 2 - Disconnect External Devices

The best way to troubleshoot this issue is by eliminating external devices one by one. First, disconnect all peripherals that are not essential for the computer to function. This includes removing all devices, then booting up the computer. Next, you can add the peripherals back one at a time.

Unplug external devices unplug external devices

Unplug almost everything that isn't essential, including printer cables, scanners, webcams, external displays, and any other devices that your computer doesn't need to run.

Solution 3 - Check the BIOS settings

Conflicts in the BIOS or UEFI settings can also prevent a computer from booting. The key you need to press to enter your computer's UEFI or BIOS settings can be found in your computer or laptop's manual.

Check the BIOS settings Check the BIOS settings

While in the UEFI settings, make sure your computer is set to boot from the primary hard drive. This is the hard drive that has the operating system installed on it. If Fast Boot is enabled, make sure it's disabled. Check for any unusual settings in the BIOS that might be preventing the computer from starting up correctly.

Solution 4: Boot your computer in Safe Mode and check for the issue

Safe Mode is one of the primary saviors when it comes to fixing issues on your computer. For instance, accessing it ensures you get unique startup options in Windows. Admittedly, getting into Safe Mode can be a bit tricky, but it's worth a shot for troubleshooting any problems you might encounter.

Start your computer in safe mode

Here are the steps to follow:

    - Hold down the Power button for 10 seconds to shut down your computer. - Consult your computer's manual for instructions on how to enter Safe Mode. - Once in Safe Mode, select the "Troubleshoot" option, then navigate through: **Advanced options** -> **Startup Settings** -> **Restart**. - After that, choose **Safe Mode with Networking**.

Check if this resolves the issue, and then disable the changes and peripherals one by one to ensure that your system is running fine.

Solution 5: Check your monitor and hardware connections (graphics card, RAM, etc.)

Check to see if your monitor is working. If your computer seems to be running but you can't see anything, the problem might be your monitor. You'll also want to verify that other components, like your graphics card and RAM, are functioning properly.

It could be that something inside your computer has become loose. If you don't mind opening up your computer, try removing and reseating each component, including the RAM, video card, motherboard cables, and CPU cooler.

Solution 6 - Boot from USB and run an antivirus

Booting from USB is one of the best ways to troubleshoot why your computer isn't starting up properly. First, make sure you have a USB drive with an operating system on it, then boot your computer from the USB drive.

Boot from USB

If you can boot your computer from a USB drive, it's a good idea to use one to run an antivirus program. This ensures that any viruses or malware are removed before you try running your computer normally again.

Solution 7 – Check the hard drive and recover data on another PC

If all else fails and you can't boot your computer, the next step is to check whether your hard drive is still functioning. If it is, you can use specialized software to recover your data, ensuring that it's accessible and transferable to a new machine.

One powerful software tool used for this purpose is the Todo PCTrans tool. If your computer's hard drive is working fine, you can use the utility to copy the data and then transfer it to another computer.
