Why My PC Won't Turn on All of A Sudden?

There can be several reasons why a PC can't start, but two specific reasons may prevent it from booting correctly under ideal conditions.

The internal power supply of your computer may be failing, or there may be an issue that's preventing the system from starting up, which could be due to a problem with the power supply entering the device, or an issue within the operating system or its files.

How to Fix A Computer Won't Turn On (7 Reliable Ways)

When a computer won't turn on, it can be frustrating, but often the solution lies in trying different fixes to determine which one works. To troubleshoot, one can try checking the power cord and outlet, ensuring the power button is functioning properly, and checking for loose connections. Additionally, checking the BIOS settings, running a system file check, and performing a hard reset can also be helpful. If none of these methods work, it may be necessary to seek professional assistance or consider replacing the computer.

7 Fixes:

Fix 1 – Check Your Power Cable

If the power cable has developed an issue, it's likely due to wear and tear or power supply fluctuations, which can cause damage to the cable.

If you have an extra power cable, try swapping it with the current one to see if it resolves the issue. If not, consider borrowing a power cable from someone else to confirm it's the cable causing the problem. If it is, you can replace it to fix the issue.

Fix 2 –Unplug the External Devices

To troubleshoot an issue, start by disconnecting all non-essential peripherals from the computer, then restart it. Gradually add each peripheral back in one by one, checking if the issue persists after each addition, to identify the problematic component.

To properly disassemble a computer, you would need to remove everything that is not essential, such as a printer cable, scanner, webcam, external display, and other non-essential components. This will ensure the computer functions properly.

Fix 3 - Check your Hard Drive and Rescue Data on Another PC

If the above methods fail to start your computer, and you're unable to boot, the next step is to check if your hard drive is still functioning. If it is, you can use specialized software to rescue your data, allowing you to transfer it to a new PC.

If your computer's hard drive is working fine, you can use a software tool like Qiling Disk Master to copy the data and then transfer it to another computer. This tool can be used for this purpose.

• Free Download
• Windows 11/10/8/7, 100% Secure

The Data Rescue feature on Qiling Disk Master is a useful tool that can recover data from a hard drive, but it requires the hard drive to be in an active status in order to work.

Step 1. Take out the disk from the old PC.

• Remove the power cord and battery from the device.
• Open the case to see the hard disk in the old PC.
• To disassemble the shell and locate the hard disk, you can start by using a screwdriver to remove the screws that hold the shell together. This will allow you to access the internal components, including the hard disk.
• To remove the hard disk, you need to disconnect it from the motherboard and any other cables that are connected to it, then carefully take it out of the computer case.

Step 2. Connect the hard disk to the new PC.

Multiple connection methods:

• To connect an old hard disk drive, use a special device called a USB hard disk drive Enclosure. This device allows you to connect the old disk to the enclosure, and then plug the enclosure into a new PC via USB.
• The USB hard disk drive adapter is a device that connects a hard disk to a USB port, allowing data to be transferred between the two. It serves as a bridge, enabling the hard disk to be used with a new PC that only has a USB port.
• If the new PC is a desktop, the old disk can be connected as the second disk.

Step 3. Recover/Migrate the applications, files, accounts from the old disk.

1. Download and launch Qiling Disk Master, then choose the "Data Rescue" mode and click "Start".

2. Browse the steps and click "Scan".

3. Check that your disk is connected to the PC. Select the old disk to recover and click "Continue".

4. To rescue your desired applications, files, and accounts, select them from the available options.

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

The PCTrans tool allows for various data management needs, including data migration on Windows PCs, moving programs to a new PC, and transferring user accounts and settings.

Fix 4 – Check BIOS Settings

Conflicts in BIOS or UEFI settings can also prevent a PC from starting. To resolve this, refer to your computer or laptop manual to find the specific keys that need to be pressed to access the UEFI or BIOS settings.

Once inside the UEFI settings, ensure that your primary hard drive, which has your operating system, is set to boot. If the option for Fast Boot is enabled, disable it. Additionally, check for any unusual settings in the BIOS that may be preventing your computer from starting up normally.

Fix 5 - Boot PC in Safe Mode and Check Problems

Safe mode can be a lifesaver for resolving computer issues, allowing you to access unique boot options on Windows. While it may take some effort to get into safe mode, it's a worthy attempt to resolve problems you're facing.

Here is how you would do it – 

• To shut down your computer, hold the power button for 10 seconds. This will immediately turn off your computer.
• Check your computer manual for options to enter safe mode. 
• Once you're in safe mode, select Troubleshoot, then go to Advanced Options, Startup Settings, and finally Restart.
• Now pick the options for Safe Mode with Networking.

To troubleshoot the issue, check if the problem is resolved after enabling the changes and peripherals. If it is, then you can disable the changes and peripherals to ensure that the system works fine. This will help identify if the issue is related to the changes or peripherals.

Fix 6 - Boot from USB and Run Antivirus Software

If your PC won't start properly, running it from a USB drive can be a good troubleshooting option. Ensure you have a USB drive with an operating system installed, then boot your computer from the USB drive to check if the issue is resolved.

If your computer can run with a USB drive, using it to run antivirus software is a great option. This will help remove any viruses or malware, and once that's done, you can try running your computer normally.

Fix 7 - Check your Monitor and Hardware Connection (Graphic Card, RAM...)

If your computer won't start, it's possible that the issue lies with the display rather than the computer itself. Check if your monitor is working properly, and also ensure that other components like the graphics card and RAM are functioning correctly.

If you're comfortable with opening your computer, you can try troubleshooting by checking if any components have come loose. This might involve removing and reinstalling components such as RAM, graphics card, motherboard cables, and the CPU heatsink, one by one, to see if that resolves the issue.

Closing Thoughts

7 fixes to help a computer not starting can be a huge issue, but trying these solutions can provide relief and improve your experience.

If you're experiencing issues with your hard drive, Qiling Disk Master can help you recover data and regain access to your files. It can provide an enhanced level of performance enhancement, making it a viable solution if other methods fail.

Shut Down Issue: Fix "pc randomly turns off" and "computer won't shut down"

1. "PC randomly turns off" Error

If your PC randomly turns off, there could be several reasons behind this issue. It could be due to overheating, where the computer's cooling system is unable to keep up with the heat generated by the components, causing it to shut down.

• The power supply might not be working due to a faulty power cord or an issue with the outlet. Check if the power cord is securely plugged in and if the outlet is working correctly. If the issue persists, it might be worth checking the power supply unit itself for any signs of damage or malfunction.
• Your PC is overheating. To resolve this, ensure good airflow around your computer and consider using a cooling pad or external fan to help dissipate heat.
• If you suspect a hardware issue with your PC, take it to a qualified technician for diagnosis and repair, and with some troubleshooting, you should be able to identify and fix the problem quickly.

2. "computer won't shut down" Error

To resolve the issue, first, close any running programs, then check your computer's power settings to ensure they are set to "shut down" instead of "hibernate" or "sleep". If the problem persists, try restarting your computer, and if it still won't shut down, there may be a more serious underlying issue.
