Solution 1 - Check the Power Cable

First, you should check the power cord for any issues. In most cases, it might be damaged due to wear and tear. However, it could also be damaged from power surges or fluctuations.

If you have extra power cords, try one of them to see if it solves the problem. You can also borrow a power cord from a colleague or friend. If that fixes the issue, then you'll know the power cord is the problem and you should replace it.

Solution 2: Disconnect external devices

The best way to address this issue is by performing a process of elimination with your peripherals. First, disconnect all devices that are not essential for the computer to function. This involves removing everything and then starting up your PC. After that, you can add your peripherals back one by one.

Unplug any external devices

Unplug any non-essential devices, including printer cables, scanners, webcams, external displays, and anything else that your computer doesn't need to function normally.

Solution 3 - Check the hard drive and recover data on another PC

If none of the above methods or fixes work 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 salvage your data, ensuring that it's recoverable and transferable to a new computer.

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.

For this purpose, the Data Rescue feature in Todo PCTrans is an excellent choice. Please note, however, that the software will only work while the hard drive is active.

Step 1: Remove the hard drive from your old computer.

• Power down the computer and unplug it. If you're working with a laptop, remove the battery as well. • Open up the case of the old computer to access the hard drive. • Use a screwdriver to open the outer casing and locate the hard drive. • Disconnect the hard drive and its cables, then pull the drive out.

Step Two: Connect the hard drive to the new computer.

Multiple connectivity options:

• USB external hard drive enclosure: Use this special case to connect your old hard drive and then plug it into the new computer via USB.
• USB hard drive adapter: This is a "cable-like" device that connects one end to the hard drive and the other end to a USB port on the new computer.
• Desktop computer: If your new computer is a desktop, you can connect the old hard drive directly as a second internal drive.

Step 3: Restore/migrate applications, files, and accounts from the old disk.

1. Download and run the Todo PCTrans tool. Choose “Data Transfer” mode, then click “Start.”

2. Look through the steps, then click “Scan.”

3. Make sure the hard drive is connected to your computer. Select the old drive you want to recover, then click “Continue.”

4. Choose the apps, files, and accounts you want to save.

5. Wait a few seconds for the data to transfer.

The PCTrans tool also enables you to meet various data management needs, including migrating data on Windows PCs, transferring programs to a new PC, and moving user accounts and settings.

Solution 4 - Check the BIOS settings

Your computer's BIOS or UEFI settings could also be conflicting and preventing it from booting. To enter your computer's UEFI or BIOS settings, look up the specific key to press in your computer or laptop's manual.

Once in the UEFI settings, make sure your computer is set to boot from the primary hard drive. This is the hard drive that stores the operating system. If Fast Boot is an option and it's enabled, disable it. Check for any unusual settings in the BIOS that might be preventing your computer from starting up properly.

Solution 5 - Start your PC 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 that you can reach unique boot options on Windows. Admittedly, getting into Safe Mode can be a bit tricky, but it's worth a shot for troubleshooting any problems you might encounter.

Here is how it could work –

- Hold down the Power button for 10 seconds to turn off your computer. - Consult your computer's manual to learn how to access Safe Mode. - Once in Safe Mode, select the "Troubleshoot" option, then navigate through: **Advanced options** > **Startup Settings** > **Restart**. - Now select **Safe Mode with Networking**.

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

Solution 6 - Boot from USB and run an antivirus

Booting from USB is one of the great options to check if your computer isn't starting up correctly. First, make sure you have a USB drive with an operating system on it, then boot your computer from the USB drive.

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

Solution 7 - Check your monitor and hardware connections (GPU, RAM, etc.)

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

It could be that something has become loose inside your computer. If you're not afraid to open up your PC, try removing and re-seating everything, including the RAM, video card, cables from the motherboard, and the CPU cooler.
