How to fix watchdog.sys Blue Screen error in Windows?

Issue: Hi, my PC is constantly crashing with watchdog.sys BSOD. This started a few weeks ago, and the behavior repeats itself every 30-40mins. To say it is disruptive would be an understatement, so it would be nice to get a fix for these crashes.

Solved Answer

The Blue Screen of Death is a dreaded error screen that is displayed on Windows-based systems when a critical system error occurs. When the BSOD appears, it means that the system has encountered a problem that is severe enough to crash the operating system, resulting in the blue screen being displayed with an error message.

When a BSOD crash occurs, the system will automatically reboot, and the user will lose any unsaved work. It's essential to document the error message displayed on the screen as this can provide valuable information on the cause of the crash, which in this case is watchdog.sys.

Blue Screen of Death crash can occur due to several reasons, including hardware or software problems, driver issues, or faulty system components. Many users reported that they experienced random Windows crashes associated with the watchdog.sys file, which usually doesn't tell much about them or how to proceed next.

This is a Windows system file and is often related to graphics drivers on the system, such as Nvidia. In some cases, people also reported sometimes getting dxgmms2.sys error when their Windows crash, which also points to the driver issue. Thus, you might be able to solve this issue by reinstalling corrupt GPU drivers.

For some users, doing so might not help to fix the watchdog.sys Blue Screen error, in which case the issue may lie somewhere else. Thus, we provide several other solutions to fix the BSOD for good, so please follow the guide below.

How to fix watchdog.sys Blue Screen error in Windows?

Fix 1. Use an automatic PC repair tool

Windows is a highly customizable system that can meet the expectations of most people. It consists of numerous components, such as files, services, background processes, and more – all of which need to work well together. Unfortunately, some components might malfunction due to one reason or another, resulting in Blue Screen of Death crashes, which can be extremely frustrating to deal with.

Because Windows is complex, it might be difficult to determine what is causing the precise issue, especially when it comes to BSOD (even if the failing file or error code is provided). To tackle these issues quicker and more efficiently, we recommend running a scan with a PC repair tool FortectMac Washing Machine X9, which can fix errors and crashes automatically for you.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
