PC doesn’t shut down completely? 7 solutions to fix it


Are you having trouble shutting down your PC properly? It can be frustrating when your computer doesn’t seem to want to cooperate. Here are 7 solutions to help you fix the problem.

1. Software issues

Solution: Try reinstalling/updating Windows.

When you shut down your computer, you may notice that it doesn’t completely power off. This is because of a software issue that causes the computer to enter a low-power state instead of shutting down completely. In most cases, this isn’t a cause for concern and can be fixed by simply restarting your computer. However, if the problem persists, it may be indicative of a more serious issue.

If your computer doesn’t power off completely, it can’t properly cool itself down, which can lead to overheating and hardware damage. As such, it’s important to take action if you notice this problem. You can try restarting your computer or running a system scan to see if any software issues need to be fixed. If the problem persists, you should contact a repair professional for help.

2. Hardware issue

Solution: Try switching the RAM slots.

When you press the power button to turn off your computer, you expect it to shut down completely. However, sometimes the computer doesn’t seem to power down all the way. This can be due to a hardware issue, such as a faulty power supply, overheated component or RAM.

Try checking for any obvious hardware issues. If everything looks fine, then try restarting your computer to see if that solves the problem. If the problem persists, contact a qualified technician for further assistance.

3. Virus/Malware infection

Solution: Install Malwarebytes and run a full system scan.

If your computer isn’t shutting down properly, it could be due to a virus or other type of infection. When your computer is infected, malicious software runs in the background, which can prevent your operating system from shutting down correctly. In some cases, the infection may even cause your computer to restart on its own.

If you suspect that your computer is infected, it’s important to run a malware scan as soon as possible. This will help to remove any malicious software that is running on your system. If you don’t have anti-malware software installed, you can download and install a free program such as Malwarebytes. Once you’ve scanned and removed any infections, your computer should shut down properly.

4. Windows corruption

Solution: Reinstall Windows.

If your computer doesn’t shut down completely, it may be due to Windows corruption. This can happen if you have installed a new program or driver that is incompatible with Windows. It can also happen if you have a virus or malware infection. To fix Windows corruption, you will need to run the System File Checker tool.

This tool will scan your system for corrupt files and replace them with fresh copies. To run the System File Checker tool, you will need to open the Command Prompt as an administrator. Then, type the “sfc /scannow” command and press Enter. The scan may take a few minutes to complete. Once it is finished, reboot your computer and see if the issue is resolved.

5. Driver issues

Solution: Update Drivers

Drivers are the software that allows your computer to communicate with the hardware components attached to it. When a driver isn’t working properly, it can cause all sorts of problems, including preventing your computer from shutting down properly. If you’re not sure which driver is causing the problem, you can use several tools out there to scan your system and identify the culprit.

Once you’ve found the problematic driver, you can either update it or uninstall it and see if that fixes the problem. In most cases, updating or removing the driver will solve the issue and allow your computer to shut down properly. However, if the problem persists, you may need to contact your computer’s manufacturer for further assistance.

6. BIOS issues

Solution: Update BIOS

Another reason your computer doesn’t fully shut down is because of your BIOS.

The BIOS is a type of software that is built into your computer’s motherboard. Its job is to start up your computer when you push the power button. It also controls other basic functions, like how your mouse and keyboard work. The BIOS stays on even when you turn off your computer because it needs to be ready in case you decide to turn it back on again.

If your BIOS is having issues, it can cause your computer to not shut down all the way. You might see an error message on your screen, or your computer might restart itself instead of shutting down. If this happens, you should check for any updates for your BIOS and install them if necessary. You can usually find these updates on your computer manufacturer’s website.

7. Fast Startup issue

Solution: Disable startup

Fast Startup works by saving a snapshot of your system state before shutdown so that it can be restored more quickly when you turn your computer back on. This can help reduce startup times, but it also means that your computer isn’t completely powered down when you shut it off. If you’re not comfortable with this, you can disable Fast Startup by opening the Power Options menu and selecting “Turn on fast startup (recommended)” under Shutdown settings. However, keep in mind that this will increase your startup time, so it’s only an option if you’re willing to trade a little bit of convenience for a little bit of extra security.
