Issue: How to Fix CLOCK_WATCHDOG_TIMEOUT BSOD on Windows 10?

Today my system crashed for two times and showed a BSOD CLOCK_WATCHDOG_TIMEOUT. I check the system regularly and optimize it, so up till now, it was working flawlessly. It has been running Windows 10 for more than a year. I haven’t changed any important settings in the past few days, except that I installed the creator’s update last week. Please help.

Solved Answer


CLOCK_WATCHDOG_TIMEOUT is a Windows Blue Screen of Death (BSOD). In comparison to pop-up errors, BSOD errors appear less commonly, but they are much more serious due to the fact that they freeze up the system and initiate forced restarts. Consequently, PC users may experience a significant damage as they may lose some files or information that they were currently working on. Antivirus software, virus infections, and driver failures are listed among the most common BSOD causes. However, the CLOCK_WATCHDOG_TIMEOUT Blue Screen may also be triggered some BIOS settings, outdated SSD firmware or some hardware issues. Therefore, if you want to fix CLOCK_WATCHDOG_TIMEOUT bug, refer to the instructions listed below and try them one by one.

To repair damaged system, you have to purchase the licensed version of Reimage Reimage.

Method 1. Check the system with a professional anti-virus

Install a professional anti-malware and run a scan with it. Our recommendation would be Reimage. Of course, you can also use the software that is already running on your OS, but make sure to update it. If the anti-virus did not detect any threats, then we would recommend you to disable anti-virus software temporarily and disable Windows Firewall. For this purpose, open the Task Manager and terminate antivirus’ process out there. Then find its icon on the taskbar, right-click it, and select Disable. Once done, turn off Windows Firewall:

  1. Click Windows key + X and select Control Panel.
  2. Locate Windows Firewall and click it.
  3. Press Turn Windows Firewall On or Off option.
  4. If required, enter your administrator password and press OK.
  5. Then set Windows Firewall off on both private and public network.
  6. Click OK to save the changes and close everything.
  7. Now you should check if these steps helped to fix CLOCK_WATCHDOG_TIMEOUT. If not, move on to the next fix.

Method 2. Update driver software

If the culprit of CLOCK_WATCHDOG_TIMEOUT blue screen is related to drivers, the installation of the driver update should be the right solution. To check that, you should:

  1. Right-click Windows key and select Device Manager.
  2. Check all devices and look for the ones marked with a yellow exclamation mark.
  3. If there are some malfunctioning drivers, update all of them. For this purpose, right-click on the driver and select Update Driver Software.

Unfortunately, but automatic driver updates via Device Manager often fails. Therefore, we would highly recommend you to install a Driver Update software and let it install the latest drivers.

Method 3. Run available BIOS updates

If the CLOCK_WATCHDOG_TIMEOUT error is triggered by incorrect BIOS settings, we would strongly recommend you to install all available BIOS updates.

  1. Click Win key + R, type msinfo32, and hit Enter.
  2. Select System Summary and find your BIOS version. Make sure that you remember the type of your BIOS. At best, write down its name somewhere.
  3. After that, navigate to the official website of your PC’s/laptop’s motherboard manufacturer and check if there is a newer version of the type of your BIOS available. If it is, download it and run its .exe file.
  4. Finally, restart your PC.

There are some additional CLOCK_WATCHDOG_TIMEOUT fixes spreading around on the Internet. However, most of them are related to the modification of BIOS settings. However, we would not recommend modifying BIOS manually unless you are a professional IT. Otherwise, you may cause some serious damage to the system and end up with a system crash.
If none of the solutions provided here did help, we would recommend you to reinstall Windows OS using a bootable Windows 10 installation media.
