Regardless of the fact that the transition to Windows 10 from previous iterations is rather seamless, certain issues can force you to reconsider the upgrade.

Especially if the error at hand is a critical system error that results in BSoD (Blue Screen of Death).

In this case, we’ll try to focus on the watchdog.sys error in Windows 10 that seems to bother a lot of folks recently.

Firstly, watchdog.sys is there to monitor the time that threads spend executing in the display driver.

So, basically, due to one or multiple reasons, the file gets missing or corrupted and your PC will crash for sure.

Since it’s related to GPU/Display drivers, predominantly Nvidia graphics, our main concern goes to false generic drivers provided by Windows update.

So, if you’re plagued by a lot of crashes lately, make sure to check the solutions below.

1. Reinstall GPU drivers

Remember the days when you needed to meddle with GPU drivers after the system reinstallation? Well, those days are long gone after Windows 10 was introduced.

And, even though the concept of auto-installing drivers is legitimately an upgrade, users with old PC configurations occasionally run into a bunch of problems.

The watchdog.sys BSoD error occurs mostly due to the incompatibility of self-installed Nvidia drivers with certain motherboard drivers.

Basically, they just pop out the latest available driver version and don’t question the possibility that it won’t cut it for the older motherboard/GPU combo.

That will, consequently, result in slowdowns or, in the worst-case scenario like this is, it’ll cause system crashes and Blue Screen of Death.

So, the first thing we’ll need to do before we move is to check those drivers. But, this time, we’ll do it by hand and that includes stopping the automatic driver updates.
