(Fixed) CLOCK WATCHDOG TIMEOUT Error on Windows 10

If your Windows 10 computer screen turns blue and displays a sad smiley face together with a long message, it means that you stumbled upon a BSOD error that must be fixed.

The worst part about it is that blue screen messages make your machine inoperable. On top of that, any unsaved projects you’ve been working on until that point will be lost.


CLOCK WATCHDOG TIMEOUT is a BSOD error caused by the processor’s failed attempts to perform interruptions. It means that the CPU isn’t properly responding to commands.

There might be a problem with how the CPU cores and threads interact with each other. For example, if your system supports multiple CPU threads, the BSOD error could indicate that one thread fails to send requests to another one.

Stop code CLOCK WATCHDOG TIMEOUT is typically accompanied by the following error codes: 0x00000101, 0x27FD1D7E, 0x372CD352, 0x94DAFD0F, or 0xCA4FBB49.


How to fix CLOCK WATCHDOG TIMEOUT on Windows 10

You might be tempted to perform a factory reset on your Windows 10 PC. But it should be your last resort. Before doing that, try the next solutions:

1. Clean boot Windows 10

If you don’t get a chance to take too many steps on your operating system because Windows 10 quickly shows the CLOCK WATCHDOG TIMEOUT error after launch, try a clean system boot.

It instructs your OS to start only essential services, drivers, and processes, turning off everything else. This gives you a chance to create a safe environment for BSOD troubleshooting.

However, if you need more advanced information for memory diagnostics, try using MemTest86. You can boot it from a USB flash drive to check your RAM sticks and remove or replace the ones with errors.

3. Disable overclocking

Overclocking means to improve the performance of your computer by increasing the clock rate of your CPU, RAM, or GPU. It’s a technique often used to enhance the gaming experience.

However, if it’s not done properly, it could cause serious problems on your machine, including the CLOCK WATCHDOG TIMEOUT error. For instance, you need additional cooling power to prevent your PC from going haywire.

How to deactivate overclocking in BIOS:

  1. Restart your PC and hit the key or key combination shown on the screen to enter BIOS mode
  2. Locate the Advanced settings
  3. Disable Overclocking
  4. Save the current configuration and exit BIOS
  5. Reboot your PC and check for BSOD errors

However, if you have installed a third-party overclocking utility, make sure to turn it off, reset BIOS settings to default, and remove the program from your computer to prevent any further problems.

4. Get the latest Windows updates

If there are any pending Windows updates, you should download and install them in order to take advantage of the newest features, improvements, hotfixes, and security features. You could even get rid of the CLOCK WATCHDOG TIMEOUT stop code this way.

5. Check your drivers

The system drivers tell your devices how to interact with each other and the operating system. So, if you have missing or outdated drivers, it could be the reason why you keep getting BSOD error codes on your computer like CLOCK WATCHDOG TIMEOUT.

You can easily fix this by reinstalling the device drivers. Or, if they’re obsolete, you should update them to the latest version.

How to easily reinstall compatible drivers:

  1. Right-click the Start button and select Device ManagerWindows 10 shows how to access Device Manager from the Start right-click menu

Unfortunately, Microsoft usually fails to find driver updates on the web although newer versions are actually available. To overcome this problem, you can visit the official website of your device manufacturer to download and install drivers.

On the other hand, if you don’t want to risk getting an incompatible driver for your computer that may cause further damage, then you should opt for a driver updating application.

It scans your computer for all drivers, finds newer versions on the Internet, and makes sure to download drivers compatible with your operating system and hardware. And it’s all performed automatically.

However, if the application in question has added or edited your system registry settings, it might not be enough to remove it with the Windows built-in uninstaller.

In that case, we advise using a programs removal tool. It automatically deletes the remnant files and restores the registry settings to default.

7. Roll back Windows 10

A better solution than uninstalling faulty programs is to roll back Windows 10 to a previous restore point. It should repair the CLOCK WATCHDOG TIMEOUT error if if was caused by software or system modifications.

10. Unplug new hardware devices

If you have recently purchased a new piece of hardware that goes into your desktop or laptop, like a USB-enabled mouse, webcam, Wi-Fi adapter, or memory card, it might have triggered hardware errors that eventually lead to CLOCK WATCHDOG TIMEOUT.

You should be able to easily fix this by unplugging all recent hardware and restarting your computer to check for improvements.

If you’re unsure, unplug everything, launch Windows to confirm that you’re not getting errors anymore, then carefully reattach one component at a time to identify the culprit.

To kick it up a notch, you could try removing all cables and cards from the computer unit. Then start plugging back everything in, making sure that the components are connected correctly but without using force.

It might also be a good idea to dust off your gear, particularly the cooler. Faulty USB ports could be another reason for BSOD errors, so you should try connecting your USB-enabled devices to different ports.

11. Check your PC for malware

Some viruses are powerful enough to disable critical processes and services, resulting in BSOD errors such as CLOCK WATCHDOG TIMEOUT. The only solution here is to perform a scan on your computer and get rid of any pests.
